4 Diagnosing Low Power Complaints

May 13,1998LEVN4384

Page 31

Quick Tip #2

Diagnosing Low Power Complaints4 Look for small customer installed mufflers. They can restrict exhaust

flow beyond acceptable limits.4 In rare cases it is possible that OEM installations are undersized. A

greater possibility is a failure of internal muffler parts that cause powerloss.

4 If you have low power and engine doesn’t sound right, disconnect theexhaust system from the turbo and test drive the truck. If the problemdisappears, check the muffler outlet for obstructions.

4 Fuel tanks can roll in their straps and kink a suction line. It may not bebad enough to have low fuel pressure on the shop floor but under load itmay starve for fuel. You could miss it on the Par Dyno Test becauseOEM fuel lines are not used.

4 Symptom:n Engine continues to run after the ignition key switch is turned OFF

4 Cause:n ECM ignition key switch circuit failed because of high voltage transient on

ignition key circuit

4 Repair:n BEFORE replacing the ECM call 1-800-340-0228 for further information.n When filter is available, install filter before replacing ECM. Information on filter

to follow in ECN.n Replacing ECM without installing Filter will cause repeat failure of ECM!

4 Caterpillar is working with vehicle manufacturers to get filterinstalled in OEM harness

4 Cause:n ECM output controller failed

4 Repair:n Call 1-800-340-0228 for further information. You will need to get an

authorization number for replacing the ECM.

4 Engine below serial number 7AS052934 Symptom:

n Batteries draining in a couple of days after truck sits unusedn Determined accessories/lamps left on cannot be the cause

4 Cause:n ECM does not go to “sleep” when ignition key switch turned off

4 Troubleshootingn Measure the current going into pins 52 and 53 of of the OEM connector. Do

this by pulling pins 52 and 53 out of the OEM ecm connector (J1), replace 53with a jumper wire and using the ammeter setting of your voltmeter,measure the current from the wiring harness pin 53 (that you pulled)through the ammeter into the jumper wire installed in the ecm. With thekey on, it should draw more than 500 ma. With the key off for more than 5minutes, the draw should drop significantly to around 20 ma.

n Repairn If the current remains above 500 ma, replace the ECM.

1. Turn off the engine and put key start switch in the "OFF"position.

2. Disconnect the NEGATIVE battery cable at the battery.If the machine or engine has a battery disconnectswitch, open the switch.

3. Connect the welder ground cable directly to the actualmachine member to be welded. Place this clamp asclose as possible to the weld to reduce the possibilityof welding current damage to the drive train bearings,hydraulic components, electrical components like cabground straps and other machine components.

Horton 3-Speed Fan Feature in H.D.Truck SoftwareHorton 3-speed fan three modes: Brake, Slip and Direct (full speed)

- "Slip" mode is used most of the time

- Two selected ECM output drivers operate each speed

- ECM has non-programmable conditions to determine the operation

May 13,1998LEVN4384

Page 47

The ECM uses MultiFunction Output #3 and #4 (MF#3 and MF#4) for driving the two solenoids.The set logic for the three speeds is as follows:

Both MF#3 and MF#4 On: Brake Mode or Zero SpeedMF#3 (Off), MF#4 (On): Slip ModeBoth MF#3 and MF#4 Off: Direct Mode or Full Speed

The minimum time for Direct Speed Mode is 20 seconds and the minimum time for Slip Speed Mode is 3 seconds.If the A/C pressure switch is active, the minimum direct on time does not apply.

If Fan in Retarder parameter is programmed to "Yes", the fan will operate at full speed when conditions are met.This will allow for maximum braking and the minimum on time in Direct mode does not apply.

The Service Tool will need to have Fan Type programmed to Horton 3-Speedand set Multi-function Output #3 to Fan and Multi-function Output #4 toCooling Fan. Failure to program these correctly will result in a 253-02diagnostic code. This will also result in the fan operating in the Direct(full speed) mode only.

n Insert the CD-ROM in the CD Driven Select the Start Button from the Windows Task Barn Select Run, and type in z:setup.exe, where z: is the drive letter for your CD-ROM drive, and select OK.n You will then see a welcome screen, select Next to continuen For the license screen, carefully read the license and select Yes to continue.n Select a destination folder for ET, chose Next to accept the defaultn Choose a program folder, select Continue to accept the defaultn Next, choose the type of install, you wish to do:

4 Custom allows you to select components to install4 Complete will install the entire ET package

n If you selected Custom, select the components you wish to install.n You are then asked to select the languages to installn Setup will then copy the files for the selected components and languages.n When the setup is complete, you will have the opportunity to open the readme.txt file and launch ET.

4 This completes a new installation for ET. Note that performing an upgrade to version 2.2 will offer slightly different options,but the basic theory is the same.

ET 2.2 Installation Demo

ET 2.2 Re-InstallIf you run setup again from the CD-ROM or diskettes you have made, you would see a different set ofscreens.

The install shield wizard will search for installed components. When install shield detects you haveversion 2.2 installed, you will see this screen.

You have three choices:

Add/Remove – to add or remove select componentsReinstall – To fix missing or corrupt filesAnd Remove – Which will remove all installed ET components. Note that this remove option doesnot remove the ET license.
