1. Introduction

1 Introduction

DID1 is an engine control unit for common rail diesel engines with upto 8 cylinders equipped with solenoid injectors. It is also capable ofdriving unit injectors as well as some spill valve controlled injectionpumps. The injector outputs have a programmable voltage boost toshorten the current rise time as well as a programmable current limitprofile. Injectors can open multiple times per firing cycle but no twoinjectors can be open simultaneously.Notable hardware features:

8 injector outputs Software configurable boost voltage up to 100V.Software configurable peak current up to 32A and hold currentup to 21A. Controllers ordered for plug-and-play operation withMercedes Benz OM61x engines have only 6 injector outputs.

11 configurable low-side switch outputs 7 of which are PWM capable.

14 0-5V analog inputs 2 of which are dedicated for accelerator pedalinput. Of the rest, 2 have 3000Ω pull-up resistors for thermistorbias, a further 2 can be configured between 57.6kΩ and 3000Ω andthe rest have 57.6kΩ pull-ups.

5 general purpose digital inputs Not counting crank/cam sensorinputs. 4 of these are frequency capable. All are 12V tolerant butwith 5V pull-ups. Inputs 1 and 2 have software configurable pull-downresistors so they can register positive voltage input.

1. Introduction

USB 2.0 for PC communication

1.0.1 TerminologySome terminology and abbreviations found in this manual:

Analog input An input on the ECU that accepts a variable voltageranging from 0 to 5 volts and the ECU will record this voltage.

BG Calibrator The software used to communicate with and configurethe ECU.

CAN Controller Area Network. A communications interface that allowsmultiple computers to communicate by joining them all to a sharedsingle pair of wires, capable of speeds up to 1 megabit per secondbut the most common configuration being 500 kilobits per second.In CAN terminology, termination refers to the connection of a 120ohm resistor between the pair of wires. Two terminations mustbe present on a CAN network for correct operation, and theseterminations can be located inside devices on the network or bythe means of resistors connected directly. For best signal integritythe terminations should be located on each end of the network if thewiring is long.

Digital input An input on the ECU that accepts a variable voltageranging from about negative 30 volts to positive 30 volts but theECU will only register whether this voltage is below positive 1 volt(active low state 1) or above positive 2.5 volts (state 0). Voltagesin between 1.0 and 2.5 volts have an undefined state as hysteresisprevents changing states inside that range. Many of the digitalinputs can record the frequency of voltage swings or interval betweenstate changes as a means of measuring speed (vehicle speed, turbochargerspeed, fluid flow rate, etc).

ECU Electronic Control Unit. Sometimes called Engine Control Unit.

Firmware The software that is installed inside the ECU.

Hall effect sensor A sensor that utilises the so called hall effect phenomenonto sense magnetic fields. Typical application crankshaft speedsensing, camshaft position sensing or vehicle speed sensing. Mosttypically has a permanent magnet built in to the sensor allowingit to sense metal teeth on rotating wheels but variants also existthat use moving permanent magnets as their targets. These sensorshave circuitry inside them and have three terminals. One terminalconnects to ground, another to a voltage supply (5V typically)and the third is typically an open collector (low-side switching)output that activates when metal is present at the tip of the sensor.Certain sensors also exist that utilise the hall effect phenomenonto measure displacement or angle of a magnet, such as solid stateaccelerator pedal position sensors.

1. Introduction

LIN Local Interconnect Network. A low speed single wire communicationsinterface typically used for small single purpose devices like actuatorsor switches. Maximum data rate 20 kilobits per second.

Low-side switch An ECU output that provides negative voltage (ground)to the circuit when activated, conducts no current otherwise. Anydevice connected to such an output such as a relay or a solenoidmust have its other terminal connected to a positive voltage supplysuch as the vehicle’s battery.

Main relay The relay that switches on power from the vehicle’s batteryto the ECU.

MAP Intake Manifold Absolute Pressure. The air pressure in the engine’sintake manifold measured in absolute pressure units.

N/C No Connection. Means a wire or pin to which no connection shouldbe made. Care should also be taken to isolate the wire so its baremetal can not make any unintentional connections.

Power ground A pin on the ECU meant to carry large currents. Thesepins must be connected to a low impedance ground, preferablydirectly to the battery negative terminal.

Pull down A resistor that pulls the voltage of a circuit close to groundlevel by sinking a small amount of current. When no other connectionis made to the circuit the circuit will float at or close to groundlevel (0 volts).

Pull up A resistor that lifts the voltage of a circuit above ground levelby providing a small amount of current. When no other connectionis made to the circuit the circuit will float at the same voltage asthe pull up resistor connects to, otherwise the voltage will dependon the current sinking capability of the connected device.

PWM Pulse Width Modulation. Where an output is pulsed on/offrapidly and the ratio between on and off time effectively modulatesthe current flowing in the circuit as well as the force enacted by theactuator it controls.

Sensor ground A pin on the ECU meant for grounding sensors to.These pins must not be connected to any other grounds in thevehicle. If significant conductance (10 ohms or below) can be measuredfrom a sensor ground pin to the vehicle’s chassis ground when theECU is disconnected from the harness then that indicates a wiringerror.

Thermistor A type of temperature sensor that exhibits a variable resistanceas a function of temperature. To measure the resistance of thesensor the ECU must feed current through it by the means of asuitably strong pull up resistor and measure the resulting voltagewith an analog input. Since the sensor is dependant on a current

1. Introduction

supply for value measurement it is not good practice to splice sensorwiring with another controller as this will interfere with the measurementsif both controllers are feeding current to the circuit.

Thermo couple A type of temperature sensor formed by a junction ofdissimilar metals that generates a small voltage when the junction isat different temperature than the other end of the wire connectingthem. Typical use in this application is for exhaust gas temperaturemeasurement. For the most accurate operation these must be connectedby special wiring that maintains the same metal alloy from thetemperature probe all the way back to the interface device.

Variable reluctance sensor (VR sensor) A sensor with 2 terminalsconsisting of a metal core, a coil of wire and a permanent magnet.Typically used to sense crankshaft speed, vehicle speed or camshaftposition (see also hall effect sensor). Typically one wire is connectedto a sensor ground and the other connects to an ECU input. Bringinga piece of metal close to the sensor’s tip produces a voltage pulseand moving the metal piece away from the sensor’s tip producesa voltage pulse of the opposite polarity. Thus the polarisation ofthe sensor’s wiring matters and the ECU will pick up some signalregardless of the polarity but if its timing is of importance (cranktrigger) the wiring polarity must be correct for correct operation.The amplitude of the signal is a function of the speed of the objectmoving near the tip of the sensor.

2. Wiring 2.3. Wiring guidelines

2.3 Wiring guidelines2.3.1 What is required

The minimum required wiring to run an engine consists of the following.All of the described sensors and actuators should be already present ifyou have a complete car with engine but some may be missing if you justhave the engine by itself.

Crankshaft position sensor (crank trigger)Supplies the ECU with information about the engine’s rotationalspeed as well as the angle of the crankshaft. The recommendedtrigger wheel tooth count is 60 with two removed. If wheel diameteris limited, as few as 36 teeth may be used with one or two removed.Fewer than this can work but are not recommended as diesel enginesare highly sensitive to the accuracy of the injection timing and canhave high rates of crankshaft acceleration. Variable reluctance orhall effect sensors can be used. Some low output variable reluctancesensors require extra amplifier modules to be installed inside thecontroller. The crank position sensor has a dedicated input onconnector 4 pin 26.

Camshaft position sensor (cam sync)Supplies ECU with information on the phase of the cam shafts.Required during start up to match crank angle to the firing orderon a 4 stroke engine. Variable reluctance or hall effect sensors canbe used. Some low output variable reluctance sensors require extraamplifier modules to be installed inside the controller. The camposition sensor has a dedicated input on connector 4 pin 3.

Rail pressure sensorIf using a common rail engine, a rail pressure sensor is required forcontrol over fuel rail pressure as well as computing the correct pulsewidth to deliver the commanded fuel quantity. The rail pressuresensor can connect to any analog input, the default is analog input4, connector 4 pin 14.

Rail pressure control solenoidMost common rail engines utilise some kind of solenoid for computercontrol of rail pressure. In some instances more than one solenoid.These are most typically located on the high pressure fuel pump butsometimes on the fuel rail itself. In the case of proportioning valves(most common) they should be connected to the high current PWMoutputs (outputs 3 or 4). In the case of synchronised suction valvesthey would connect to outputs 9 or 10.

Fuel injectorsThis controller operates solenoid valve type injectors. These are themost common injectors found on common rail diesel engines. Todistinguish solenoid valves from the less common but still commonpiezoelectric valves, set a multimeter to mesure resistance in the

13


range closest to 0 ohms. A solenoid will read less than 10 ohmscontinuously, a piezoelectric actuator will measure open circuit (noconductivity).

Accelerator pedalNot required to start the engine but required to operate above idlespeeds. The accelerator pedal wiring must be uncompromised withno connection to other devices than the ECU and preferably notshared with other sensors. The accelerator pedal should preferablybe of dual potentiometer or solid state type with dual analog voltageoutputs. Potentiometer + idle switch as commonly found on olderdiesel cars may also be used.

Components that are not as such required for start up but recommendedfor normal operation:

Intake Manifold Absolute Pressure sensorRequired for turbocharger control as well as limiting fuel duringtransient conditions. The MAP sensor has a dedicated input whichis analog input 6 (connector 4 pin 6).

Coolant temperature sensorThe engine’s characteristics are different when cold than when it isat operating temperature so best cold start and cold idle behaviourcan not be achieved without coolant temperature data. Coolanttemperature data is also required for automated control of glowplugs and cooling fans. There is not a dedicated input for the coolanttemperature sensor but the default is analog input 2 (connector 4,pin 36).

Charge air temperature sensorThe density of the air is a function of air temperature, and whilea diesel can tolerate large variations in oxygen to fuel ratio it is agood idea to have a charge air temperature sensor to compensatefor air temperature and avoid overfuelling on a hot day with a heatsoaked intercooler.

Glow plug relayIf the engine in question has glow plugs or other means of heatassisted cold starts, the ECU can control this. Two types of controlare supported, a standard general purpose relay or a Mercedes BenzPWM glow controller as found on any electronically controlledMercedes Benz diesel engine from 1996 until about 2006, with4, 5, 6 or 8 cylinders. The same units have been found on someVolkswagens and possibly more cars that are not Mercedes Benz.PWM refers to the communications protocol these controllers useto communicate with the ECU, they do not employ pulse widthmodulation as a means of controlling glow plug temperature. Atraditional relay can be controlled by any of the programmableoutputs but a PWM glow controller should use output 11 (connector

14


3 pin 25) as that pin provides bidirectional communications allowingdiagnostics of glow plug performance.

Turbocharger controlThe DID1 ECU can control turbochargers, either with variablegeometry or wastegates. Single, dual or even triple turbochargers,parallel or compound. In most instances this is done by PWMcontrol and requires a solenoid valve to modulate the vacuum orpneumatic pressure on the actuator diaphragm. Programmableoutputs 5 through 8 are typically used to perform this function. Forelectronic VGT actuators the method of control varies. Some usePWM control while others require CAN bus communication or evenLIN bus communication. The DID1 ECU can support all of thesebut at the time of writing no LIN bus turbo actuator protocols havebeen coded.

Lift pumpThis is an area where engines vary wildly, some have a mechanicallow pressure lift pump integrated or attached to the high pressurepump. Others require an electric lift pump to feed the high pressurepump.

2.3.2 Plug and play Mercedes Benz configurationThe controller is designed to be plug and play for Mercedes Benz OM611,OM612, OM613 engines. However due to some differences between thewiring of different chassis containing these engines some modificationsto the car’s wiring may need to be done. The controller is designed to befully plug and play for a W210 E320 CDI, other cars may need modifications.In the case of the W163 ML270 CDI, W210 E220 CDI, W210 E270 CDIor other cars with OM611 or OM612 engines the following wires need tobe moved around:

3-40 N/C blue Remove wire to avoid interfering withon board diagnostics

3-28 N/C orange Remove wire to avoid interfering withon board diagnostics

2.3.3 GroundingThe controller should be connected to the battery negative terminal oranother reliable grounding point by a no less than three 1.5 mm2 (14-16AWG) wires running in parallel. Length of ground wires should be keptas short as practical. An improper ground connection will cause electricalnoise and possibly faults with controller operation.Any sensors connected to the ECU must not be grounded elsewhere thanto the ECU’s sensor ground pins unless they are isolated circuits. Underno circumstance whatsoever may the controller’s sensor ground pinsbe connected to any wiring that already has a connection to any otherground point in the vehicle at the risk of degraded sensor signal integrityand controller damage.

2.3.4 12V feedThe controller requires no less than two 1.5 mm2 (14-16 AWG) runningin parallel or a single 2.5 mm2 (12 AWG) to the battery positive terminalthrough a fuse or circuit breaker and a relay. Power is to be fed into pins7 and 8 of connector 1 and the circuit should be fused at 15-20A. Keepwiring as short as possible to limit electrical noise and voltage drop. Asecondary supply for external accessories must also be wired for correctoperation. This supply goes to pin 1 of connector 1 and should be fusedat 10A.

2.3.5 Analog sensor inputsThe analog sensor inputs have an input range from 0 to 5 volts. Underno circumstance may these inputs have voltages below 0 volts or above 5

16


volts supplied. Although the inputs are protected against damage in suchsituations the signal integrity of all analog inputs is compromised whenany of the inputs are receiving voltage outside of the design range. Forthe greatest accuracy and repeatability, sensors that output an analogvoltage should use the 5 volt reference outputs provided by the controller.

2.3.6 InjectorsIf the ECU is ordered as a plug and play unit for Mercedes Benz OM61xengnes there will be three pins providing positive voltage to the injectors.If the ECU is ordered in the 8 cylinder capable version it will have justone pin supplying positive voltage to the injectors and the other two pinsbecome negative outputs for injectors 7 and 8.For best performance the positive and negative wires for each injectorshould be twisted together all the way from the injector and the positivesupply wires for the injectors should be joined close to the ECU. It isimportant to have very low resistance in the injector wiring so the wiresshould not be made longer than they need and they should use heavygauge conductors. In any case no smaller than 1.5 mm2 (14-16 AWG) asthe resistance and inductance of these wires has an effect on the injectorsability to open quickly. An exception can be made for injectors thatrequire less than 10A peak current. Those can be wired with smallergauge wiring.

2.3.7 Switching and PWM outputsThe ECU has eleven programmable outputs and while all low speedfunctions are applicable to every output, some PWM functions havededicated outputs. This means that if those functions are used, theycan only be assigned to the specified output. The outputs are low-sideswitches meaning the negative terminal of whatever device that is tobe switched on is wired to the controller. The outputs are rated for 3Acontinuous current and 5A intermittent with the exception of output 11so anything that draws more current must be wired through a relay. Alloutputs except 3 and 4 have a 30 volt flyback voltage clamp built in butmay need an external flyback diode for high current high frequency PWMoperation.Pins 4-21 (Output 3) and 3-50 (Output 4) have flyback current diodesrestricting flyback voltage to supply voltage, making them suitable forcontinuous PWM operation of loads greater than 1A current and greaterthan 100Hz. This also makes then unsuitable for switching accessoriesthat are live when the supply to the ECU is switched off. Outputs 1 and11 have pull-up resistors so their connection to devices that have constantpower should be evaluated first, the exception to this is something likethe Mercedes Benz smart glow plug relay which does not pull the dataline high by itself even though the glow relay is powered directly off thebattery.

17


2.3.8 Glow plugsThe ECU can control any standard glow plug relay as well as Mercedessingle wire smart glow relay. The glow plugs are normally controlled byoutput 11, pin 3-25. Note that this output pin is not rated for currentgreater than about 1A so make sure the relay being used does not have acoil resistance of less than 12 ohms or use a different pin if this is not thecase.The Mercedes smart relay has a few connections. An M6 stud that connectsdirectly to the battery positive terminal. A big connector with 6 pins thatconnects to the glow plugs. The same relay fits 4, 5 or 6 cylinder engines,4 or 5 cylinder engines will just leave some pins unused.Then there is a small connector with three pins. The pin terminals arelabeled 31 for ground, DL for data link and TK which is not used. Theground wire is brown and the data link wire in the middle is usuallywhite but sometimes uses other colours.To control the Mercedes glow relay, the output used must be configuredfor PWM glow control in the Calibrator software. If using a modifiedMercedes relay or using any general purpose relay, select the Glow controlsetting for the output.Control of the Mercedes glow relay is only precise to the nearest secondor so. If heating time of less than 1 second is specified the relay may notturn on at all.The output used to control the Mercedes smart relay must have a 12Vpull-up. The ECU has built in pull ups on outputs 1 and 11.Output 11 has the ability to do bidirectional communication with theMercedes Benz glow relay, if this output is used for communicating withthe relay the ECU can detect and report the health of each individualglow plug. When a defective plug is detected the glow indicator will flashrapidly for a few seconds after glow plug preheating has ended and theCalibrator application will list glow plug errors in the controller error listfound under the Communications menu.

2.3.9 MAP sensorThe ECU expects the intake manifold absolute pressure sensor to beconnected to input 6 (connector 4 pin 6). Typically the MAP sensor willalso take 5V power from pin 4-8 and sensor ground from pin 4-7.If using a 4 bar GM style MAP sensor such as the one sold in the webshop, the table below describes its wiring:

If using a cylindrical MAP sensor such as the 5, 6 or 10 bar units sold inthe web store, the wiring is as follows. Note that pins are labeled as iflooking into the connector on the sensor itself.

MAP pin Function ECU pinA sensor ground 4/7B +5V feed 4/8C signal 4/6

2.3.10 Rail pressure sensorThe fuel rail pressure sensor does not have a dedicated input but typicalconnection is analog input 4 (pin 4-14) with 5V supply taken from pin4-13 and sensor ground at pin 4-4.

2.3.11 Temperature sensorsThe temperature sensors do not have dedicated inputs but two analoginputs are provided that have a non-configurable 3 kilo ohm pull upresistor to them. Typical usage is to wire the coolant temperature sensorto analog input 2 (pin 4-36) and charge air temperature sensor to input 3(pin 4-23) with sensor ground pins 4-27 and 4-34 used for return.Analog inputs 10 (pin 3-16) and 11 (pin 3-17) have a software controllable3 kilo ohm pull up associated with them so these can be used to connectthermistors as well.

2.3.12 Crank and cam position sensorsFor the crank and cam position sensors, both variable reluctance and halleffect type sensors are supported.The crank position sensor has a dedicated input on pin 4-26 and a sensorground on pin 4-37. If using a hall effect sensor it will need a 5V supply,this would typically come from pin 4-1 or 4-12.The cam position sensor has a dedicated input on pin 4-3 and typicallyuses sensor ground pin 4-2 and +5V supply from pin 4-12.

2.3.13 Pedal position sensorThe ECU can utilise either single potentiometer with idle switch as foundon most older electronically controlled diesels (including Mercedes OM60x)

19


as well as dual potentiometer and solid state units.It is highly recommended that the pedal wiring is of uncompromisedintegrity, with no branches to other devices, only connecting directly fromthe ECU to the accelerator pedal and not sharing these signals with anyother devices in the car. If you require an accelerator position signal foranother device such as a transmission computer, sharing the signal viaCAN bus is the preferred option but if that is not possible the DID1 ECUprovides an analog output that can be configured as a function of theaccelerator pedal position.

3. Software configuration

3 Software configuration

Refer to BG calibrator manual for introduction to the PC application.

3.1 Getting startedIt is advised to leave the injectors disconnected until correct operation ofrail pressure control, crank trigger and accelerator pedal has been verified.The default configuration has the configurable outputs all disabled toavoid conflict with different cars after firmware upgrade. It is advised tocheck for firmware updates from the web site prior to first start, see thenext section for information.Steps to perform before starting engine:

1. Check accelerator pedal operation. Verify that app variable readsless than 0.0% when the pedal is released and that it reacts tomovement of the pedal.

2. Check that rail pressure reads close to 0 when engine is stoppedon a common rail application. Applications without a rail pressuresensor (not common rail) should set the minimum rail pressure toallow starting to 0.0 bar in the Starting section of the configuration.

3. Check that temperature sensors are operating, check variablesairtemp and coolanttemp read reasonable values and performcalibration if they do not. These temperature sensors are not absolutelyessential to operation of the engine so if they read incorrectly thatmay be put aside to be solved after first start up.

4. Check that the correct number of cylinders, firing order and injectoroutput assignment is configured. Some common engines are foundin the configuration presets (found in the Tools menu at the top ofthe screen in Calibrator).

5. Configure the programmable outputs, the presets (found in theTools menu as configuration presets) are a good starting point.

6. Check that ignition switch and main relay are working, ECU powerson and off again when required. If ECU remains powered on it willbe difficult to stop the engine and this must be rectified beforeattempts are made to start the engine.

3. Software configuration 3.2. Performing firmware upgrades

7. Verify correct operation of crank trigger. Run starter with injectors(connector 5) disconnected and verify that the Calibrator softwaredisplays engine speed as well as syncstate variable having a valueof 7 after the starter has operated for a couple of seconds and that asteady but slightly varying engine speed is displayed while cranking.

8. Verify correct operation of rail pressure control. This can be doneat the same time as the previous step. Run the starter with noinjectors connected and see that the railpressure variable climbsafter starting for a while and then finally settles on a stable valuethat is not greater than the railtarget variable. If there is airin the fuel system it may take a minute of cranking before railpressure is observed and controllable. This step does not apply toapplications other than common rail engines.

9. Now is a good idea to record an event log while cranking the engineand verify that the firing order and injection timing looks correct.This is done from the logging menu at the top of the screen of theCalibrator software. The ECU must be connected and another datalog must not be in progress to enable this option.

10. If problems are observed, rectify them before continuing. Contacttechnical support for advice if anything is not clear.

11. Connect injectors and attempt to start engine.

3.2 Performing firmware upgradesWhenever new features are introduced, new firmware becomes availablefor download at https://controls.is/firmware/. See the release notesif you are unsure of whether you should update or not.To perform a firmware upgrade:

1. Download firmware package from web site

2. Unzip firmware package into a directory on your hard drive

3. Connect USB cable between ECU and PC.

4. Power on ECU, do not start engine.

5. If you do not have the configuration backed up, run BG Calibrator,read configuration from ECU and save to file. This step may beskipped if you are performing the upgrade on an ECU you haven’tmade any previous configuration changes to.

6. Run upgrade.cmd in directory where firmware files are located.

7. Wait until the upgrade application finishes, should be on the orderof 10 seconds.

8. Power ECU off.

22

https://controls.is/firmware/

3. Software configuration 3.2. Performing firmware upgrades

9. Do not power ECU back on until you are ready to upload configurationto it.

The ECU has been upgraded but now contains the default configuration.If you are proceeding with default configuration, simply open the defaultconfiguration file for the new firmware in BG calibrator and go on-line.Otherwise, if you wish to retain your previous configuration, which isgenerally recommended, perform the following steps:

1. Run the BG Calibrator software

2. Open your old configuration file

3. Select File -> Convert configuration from the menu bar.

4. Select the configuration included with the new firmware in the filedialog.

5. The configuration has now been converted to the new format, saveit and the Calibrator software will restart.

6. Review the settings and verify that they make sense, see releasenotes for information about what settings may need revisiting.

7. Go on-line and power on the ECU. Do not start engine.

8. When prompted, select to use local settings, which will then beuploaded to the ECU.

After the configuration has been sent to the ECU and Calibrator applicationbecomes responsive again, power the ECU off and then back on. Now youcan start the engine.

4. Extended features

4 Extended features

4.1 Cruise controlThe cruise control requires three switches wired multiplexed into anyanalog input through different value restistors to ground or alternativelyfrom a CAN bus source. Typically the resume/accel switch goes via22kΩ resistor to ground, the set/decel switch goes via 10kΩ resistorto ground and a cancel switch directly to ground with no added seriesresistance. For best results these switches should ground to a sensorground on the controller. For cancel input, one should at least have abrake pedal switch (or relay actuated from the brake light circuit) butmay also have others wired in parallel such as a clutch switch and/orhand operated cancel switch. For automatic transmission applications, avehicle speed input is necessary for cruise control operation. For manualtransmission applications it is recommended that the vehicle speed inputis wired for safety reasons (blocking cruise control from engaging belowa certain vehicle speed) but not strictly necessary. If a visual indicator isdesired when the cruise control is active, use one of the general purposeoutputs and set a condition to turn on when flag_cruise = 1. For smoothoperation of the cruise control, the road speed signal must be reasonablyclean. If you are seeing variations of several km/h indicated when holdinga steady speed you may be able to correct that using the VSS smoothingand pulse averaging functions.The cruise control has a number of outputs that are of interest in the realtime data feed.

4. Extended features 4.2. OBD2 communications

4.2 OBD2 communicationsIt is possible to perform OBD2 over CAN bus communications with theECU on CAN bus 1. This enables the use of accessories that can displayOBD2 data for instrumentation purposes (various OBD2 gauges, mobilephone applications and scan tools) as well as diagnostic trouble codereadout. The protocol implemented is ISO15765-4 11 bit OBD over CAN.To enable this functionality, the following configuration parameters mustbe set:

CAN bus data mode 500kbit

CAN receiving enable Enabled

OBD2 service enable Enabled

For diagnostic trouble codes, see Appendix A

4.2.1 Wiring

Figure 4.1: OBD2 female connector as seen from the end the scan toolplugs in to.

The OBD2 connector has four essential connections. Pin 6 (CAN-H) .Pin 14 (CAN-L) . Pins 4 and 5 connect to ground (any chassis groundwill do) and pin 16 connects to +12V. The standard specifies that the+12V should be taken through a fuse directly from the battery but mostOBD2 devices will also perform correctly if the 12V source is switched.For correct operation it may be necessary to have a 120 ohm terminationresistor connected across the CAN wires if there is none connected to theCAN bus already.

4.2.2 Custom OBD2 PIDsThe ECU already implements nearly every standard OBD2 PID that isapplicable to this application, but there are plenty of common sensorsfor which there is no documented standard OBD2 PID (for example, oilpressure) and also lots of examples of the ECU being used to monitorcustom sensors. To facilitate this, custom OBD2 PIDs have been provided.The custom PIDs can be used to add PIDs and they can also overrideexisting PIDs if desired. For a list of defined standard PIDs see https://en.wikipedia.org/wiki/OBD-II_PIDsIt is safe to define custom PIDs in the range of 197 up to 223 (0xC5 to0xDF in hex) without conflicting with any predefined PIDs.

25

https://en.wikipedia.org/wiki/OBD-II_PIDs

https://en.wikipedia.org/wiki/OBD-II_PIDs


In the Torque app, the OBD2 command to retrieve these values is 01succeeded by the PID in hex, so to get PID 197 for example it would be01 C5 OBD2 specifies the data is always in big-endian format meaningthe most significant byte comes first, so the following data types areprovided, but for most scenarios it is recommended to stick to either u8or u16be:

bit Single bit to indicate a status, 1 or 0. Treat the same as a u8 bytebut with only 2 possible values. Example formula in Torque app: A

u8 Single unsigned byte ranging from 0 to 255. Example formula inTorque app: A

s8 Single unsigned byte ranging from -128 to 127. Example formula inTorque app: SIGNED(A)

u16be 2 byte 16 bit unsigned integer ranging from 0 to 65535. Exampleformula in Torque app: INT16(A:B)

s16be 2 byte 16 bit signed integer ranging from -32768 to 32767. Notsimple to use in Torque app, use unsigned value and offset it usinginput/output scaling on ECU instead.

u32be 4 byte 32 bit unsigned integer ranging from 0 to 4294967295.Example formula in Torque app: INT32(A:B:C:D)

s32be 4 byte 32 bit signed integer ranging from -2147483648 to 2147483647.Not simple to use in Torque app, use unsigned value and offset itusing input/output scaling on ECU instead.

4.2.3 Transmitting data backThe ECU provides a set of remotely manipulable bits that can be usedto trigger things on or off, switching calibrations, etc. These bits canbe manipulated by Calibrator scripts using the remote procedure callremotebit or using OBD2 commands.To access the remote bits from OBD, use the AA command. The commandtakes 2 arguments. First argument is the bit number, from 00 to 07 andthe second argument is the action to perform. The possible actions are:

00 Flip bit to 0 state.

01 Flip bit to 1 state.

02 Toggle bit between states.

03 Do nothing, just return current value.

04 Flip bit to 1 momentarily and then back to 0 about half a secondlater.

26


The AA command sends a reply on channel EA with two data bytes, thefirst data byte being the bit number that was accessed and the seconddata byte being the new state of that bit. To read the status of a bitusing a custom PID in Torque, send the command AA 00 03 where 00is the bit you wish to read. The formula for the return data is simply B.To alter a bit from Torque create a push button widget that sends a rawOBD command, for example AA 00 02 to toggle bit 0 between states eachtime you push the button.Manipulating these bits from a Calibrator script can be done in a similarmanner. Example:[ "rpc", "remotebit", [ 0, 2 ] ] to toggle bit 0.

27

A. Error codes

A Error codes

The error codes are stored on three bit masks, error0, error1 and error2,as described in the previous chapter. They can be read using the Calibratorapplication (Communication -> View controller errors in on-linemode, Tools -> Decode error variables in log view mode). It is alsopossible to read the errors using an OBD2 scan tool if OBD2 connector iswired and OBD2 communications are enabled in the configuration. OBD2DTC codes take the form of P3XZZ where X is the error variable, 0 forerror0 and so on and ZZ is the bit offset in that variable, starting with 00.Note that these codes do not correspond with any auto manufacturer’scodes.

Errors that prohibit engine starting:

G. Toyota 1KD-FTV wiring (early)

G Toyota 1KD-FTV wiring (early)

This chapter covers the early Toyota 1KD-FTV engines as found in theToyota J90 chassis and others that use a Denso HP2 rail pump (dualcylinder pump featuring two suction control valves).The factory ECU uses a separate power supply (driver module) for theinjectors. This module is not used and not supported by the DID1. Whenutilising the factory wiring it is possible to splice the feedback wire forthe injector driver module to the common positive wire that goes to theinjectors and splice the signal wires from the ECU to driver module tothe injector wires when removing the connectors for the driver modulefrom the harness.The crank and cam position sensors on this engine output a low voltageso amplifier modules are required that install inside the DID1 ECU toboost those signals.Wiring of engine devices:

VSV EGR Valve (V3 and V14) This item is not supported, no connectionrequired.

Glow plug relay (Sub glow relay) In the Toyota this relay is activatedby +12V supplied from the ECU. To use this with the DID1 youmust either rewire the relay to be activated by a grounding outputor fit an intermediate relay to convert the grounding signal to a+12V signal.

Suction control valves (S35 and S36) These valves require currentlimiting. The tested configuration is to use a 4.7Ω power resistorin series with the common supply wire. This power resistor shouldhave a power rating of 10 watts minimum (25W advised) and asmall heat sink is advised. Only one resistor required for bothvalves as only one valve operates at any given time.Device pin Wire colour Function OEM
