The VCI Search function will affect the access to the internet connection. The KDS Wi-Fi is put on hold when the tablet is searching for the VCI. The information below explains some of the VCI functions.

KDS – VCI II SEARCHING AND CONNECTIONS

Searching

When the KDS program is opened, the VCI II search is initiated. While the KDS is searching for the VCI II, the Wi-Fi will slow down or stop altogether until the VCI II is connected. The VCI II search can be turned off.

VCI II - OFF

The VCI II can be turned off whenever it is not needed. When in VCI II search mode, tapping the VCI soft key will turn the search function off. Once the VCI II is connected, the VCI II must be removed from the vehicle and back to search mode before it can be turned off. The KDS will allow the VCI II to be turned off in Home, Search, and Service Information pages.

Bluetooth Connection

When the VCI II is first connected, the KDS uses Bluetooth for communication. Bluetooth connects rather quickly. The tablet and VCI II should be within 3 to 6 feet and in line of sight.

Wi-Fi Direct Connection

After the VCI II is connected via Bluetooth, the VCI II will connect using Wi-Fi Direct. This can take about 30 - 45 seconds. Wi-Fi Direct is a more stable connection. Performing ECU reflashes require Wi-Fi Direct.

The screenshot below shows that while the VCI II Search function is running, the Wi-Fi usually will not work.

VCI II Tips

• Once the VCI II has been disconnected from the DLC, the KDS will start searching for the VCI II.

• Usually the KDS has to be on the Home, Search or Service Information pages before the VCI search can be turned off.

• When the VCI II is left in the vehicle and out of range from the tablet, the KDS will start to search.

- Make a habit to have the VCI in hand before turning off the search function. The VCI is small and is easily left in the vehicle.

- A lanyard can be attached to the VCI II to help keep track of the VCI II

QUESTION ANSWER

I replaced the cylinder head for another concern and now I have a code for camshaft timing that I didn’t have before?

Some Kia replacement heads may have different configurations and require a round or slotted oil control valve. Please refer to PitStop PS 201.

SC114 failed to complete in auto and manual modes. Gets to (50-80 percent) and stops?

Make sure you are doing the update in manual mode and using the part number off the PCM in the vehicle. Some technicians are using the part number from the catalog and getting the wrong PCM number. Use the correct part number and the corresponding password in manual mode and the update should complete.

How do technicians tell which connectors at the PCM is connector “A” or connector “B” for performing circuit checks?

When you pull up the wiring diagram and click on the PCM connector (either “A or “B” connector) link it will pull up the connector view showing all the pin locations. To ID the correct connector now click on "Component" and the view will show you which PCM connector is A and which one is B.

I am not sure how to test the drive motor on the Hybrid/PSEV Soul or how to use the Fluke 1507 meter, can you help?

Please refer to Tech Times Volume 17, Issue 4 page 3 for information on testing insulation resistance with the Fluke 1507 meter.

DTC P0315 - CRANKSHAFT POSITION (CKP) SENSOR VARIATION NOT LEARNED (ALL MODELS W/3.3L GDI ENGINE)

When encountering a customer complaint of engine misfire with a Malfunction Indicator Light (MIL) on in the dash on all models equipped with 3.3L GDI engine, check for the presence of DTC P0315 – Crankshaft Position Sensor (CKP) Variation Not Learned. Use the VMI to view the scope pattern of the crankshaft position sensor signal. Verify a good equal crankshaft sensor pattern is present with no dips or variation, as shown in Figure A, in the sign wave pattern. If the pattern is identical to Figure A, Use GDS/KDS to perform a crank sensor relearn procedure. If the pattern shows a dip or variation, as shown in Figure B, replace the flex plate to resolve the concern.

In this article, we will show you how to identify connector terminal sizes and the current T-Connectors that are available to check terminal pin fit, test electrical circuits, use the scope, and perform input simulation tests.

Currently Kia’s use two (2) types of electrical terminals:•0.64mm (0.025”)

- Square- Blade

•0.80mm (0.040”)- Round (Delphi PCM ONLY)- Blade

JOE’S CORNER – TERMINAL MADNESS! (Terminal Identification)

So how do you tell the difference?• Sometimes the connector “Vendor P/Name” in the ETM

will give you the information

• Other times you need to measure

• And other times you need to take an educated guess!

So how do you check pin fit? T-Connectors will take care of most of the terminals used in Kia vehicles.

The tables below show which T-Connectors match which terminals.

Pin fit plays an important role in circuit operation. So how do you check pin fit?

When you don’t know, always assume that the terminal thickness is 0.64mm.

Never insert a male terminal with a thickness of 0.80mm into any female terminal unless you have confirmed its size.

Match the width of the T-Connector with the male terminal in the opposite connector.

You can also carefully remove one of the male terminals and measure it. Then you know for sure.

Check all the female terminals. If they are all loose, you can probably guess that they are a 0.80mm type.

If only some are loose and the others are good, the loose ones need either replacement or have to be tightened.

If the terminal tension is good, visually inspect the male terminals for any corrosion and correct if necessary. Use a shot of canned air to remove any loose debris from the connector.

Don’t use shop air! It may contain oil or moisture, which will give you more problems.

Apply STABILANT 22A to all the male terminals in the connector you tested. Yes, it is expensive but it will enhance the connection by ten times (10x).

Apply the STABILANT 22A using the applicator that comes with it. You only need a very small amount on each terminal. Allow it to dry for at least five (5) minutes before reassembly.

Do not use any type of dielectric grease. It may give you more problems than you already have.

It sounds like a lot of trouble but if you take your time, perform a good inspection, and use STABILANT 22A when needed you’ll know that part of the circuit is in good shape.

In my next article, I will show you how to use an ohmmeter to check CAN lines for Opens, Shorted together, and Short to ground.

SUN VISOR LIGHTS ARE INOPERABLE OR STAY ON (2016MY SORENTO UMa)

When diagnosing a concern on some 2016MY Sorento related to inoperable, or constantly on, sun visor courtesy lights, check the condition of the Interior Lamp 10A fuse. If the fuse is blown, inspect the harness on both sun visors for the possibility of frayed wiring causing a short to ground (A) or a severed harness creating an open circuit. If either sun visor harness is visibly damaged, replace the affected sun visor to resolve the concern. Finally, replace the Interior Lamp fuse if needed, and test for proper sun visor courtesy light operation.

2016MY SORENTO (UMa) - CENTRAL GATEWAY OVERVIEW

The 2016MY Sorento (UMa) is equipped with a newly designed Controller Area Network (CAN) Communication System. This new system utilizes a “Central Gateway” which is integrated into the IPM. The redesigned IPM is now known as the Integrated Gateway Power Control Module (IGPM).

One of the benefits of this system is the ability to inspect the resistance of individual CAN systems, at a centralized connector. This connector can be found on the reverse side of the IGPM, specifically, connector I/P-H (see diagram below), and does not require major component removal to access.

NOISE FROM REAR ON HARD ACCELERATION OR WHEN TURNING (2016MY SORENTO UMa)

When diagnosing an unusual noise from the rear of a 2016MY Sorento (UMa), equipped with All Wheel Drive (AWD) and built prior to June 18th, 2015, inspect the rear propeller shaft for evidence of contact with the heat shield during hard acceleration from a stop, or while turning. If contact is found (see image below), refer to the procedure outlined in this article to resolve the concern.

Service Procedure:

1. Inspect the propeller shaft for evidence of contact with the heat shield.

2. If evidence of contact is present, remove five (5) bolts and one (1) nut securing the heat shield in place, as shown.

3. Grasp the heat shield from either side and apply inward pressure to slightly modify the shape and increase clearance.

4. Reinstall the five (5) bolts and one (1) nut to secure the heat shield to the mounting locations. NOTE: To maximize clearance, make sure to align the edge of the mounting hole on the heat shield with mounting location on the body, as shown to the right.

Please refer to PitStop PS 419

Inspection of each system can be accomplished by utilizing a “T-Connector” (Part # TCLE-020 F 0.64mm Square) in-line between the male and female pins. Terminating resistance values of the IGPM alone can be tested by removing the male pins of the “T-Connector” from the female side of I/P-H.

Refer to the “Data Link Details” section of the wiring diagram on the vehicle you are servicing, for specific pin locations.

DIAGNOSTIC TIPS

The C-CAN and P-CAN system utilize two 120 Ω resistors per system, while the D-CAN system utilizes one 60Ω resistor per system. The B-CAN and M-CAN systems contain terminating resistors that are not interconnected between their respective high and low lines; as a result, they cannot be tested.

When diagnosing intermittent concerns, leave the “T-Connector” in-line with the IGPM and I/P-H connector, and observe the readings while conducting simulation testing.

Refer to the table below for known good values.

TECH TIMES • Vol 18, No. 4•20158

A/C OVERVIEW

A/C system diagnosis can sometimes be a challenge; this article will discuss some important areas to remember when working on A/C Systems.

Principals of Operation

A compressor is used to move refrigerant (R134a) through the system. The refrigerant is pressurized by the compressor. The high pressure refrigerant is pushed through the condenser where it is cooled by ambient air passing through the condenser. This cooling helps the refrigerant to change state (condense) into a liquid. At this point, the refrigerant is high pressure and mostly liquid. In the receiver/dryer, most of the vapor is trapped and liquid moves on. As the refrigerant passes through the expansion valve, it expands into the Evaporator which is low pressure. The drop in pressure causes the refrigerant to vaporize. The evaporation requires heat which is extracted from the ambient air passing through the evaporator coils. As a low pressure vapor, the refrigerant is drawn back into the compressor to repeat the cycle.

Perform a Quick Check

Check for operation of the following:

• Fresh/Recirculate actuator and door – Feel for air at vents as the modes are changed• Temperature actuator(s) and door(s) • Mode Actuator(s) and door(s)

• Blower control – Run through the blower speed and confirm operation

• Compressor command and response – Check that the compressor is turning

Perform a Performance Test

Start engine and turn on the Air Conditioning

In front of the grill, measure and record:

• Relative humidity

• Ambient air temperature

Bring engine speed up to 2000 rpm, and allow the system to stabilize for two (2) minutes

With the engine at 2000 rpm, measure and record:

• Right center air outlet temperature (with temp gauge)

• Low side pressure

• High side pressure

Allow the engine to return to idle.

Compare your recorded values to the maximum values shown in the Universal Chart (last page) to determine if the system is cooling satisfactorily.

Current Data

On manual climate control systems there is usually no current data, so the following shows typical Engine current data, with the engine running and A/C switch on and blower on.

• If the AC request by ECU is OFF - inspect A/C switch and related circuitry.

• If only A/C ON condition is OFF - inspect the evaporator temperature sensor and related circuitry.

If the climate control module perceives a freezing evaporator, it will not request compressor operation. High side operation pressures depend on ambient temperature and humidity, but generally fall in the range of 150-250psi. If the pressure is too low (< approx. 32psi) or too high (> approx. 450psi) the PCM will not energize the compressor.

Actuation Tests

Use the Actuation tests as a way to determine if the cooling fans and compressor can operate. With Automatic climate control systems the air mix and mode position actuators can also be commanded.

Electrically Controlled Variable Compressor

The Electrically Controlled Variable Compressor has a solenoid to control the compressor output. The Climate Control Module controls the solenoid through pulse width modulation (PWM) to increase or decrease the amount of displacement of the compressor. You can test the operation and control of this solenoid by monitoring the signal with the VMI / oscilloscope. The solenoids are ground side controlled by the AC control unit. The higher percentage of negative duty, the greater the compressor output. The AC Compressor test in S/W Management on the GDS or KDS can also be used.

In Conclusion

In addition to the items mentioned above, remember that proper airflow through the condenser, correct refrigerant charge, and an engine cooling system in good working condition are also vital to ensure a properly operating air conditioning system.

ELECTRIC CONTINUOUS VARIABLE VALVE TIMING (E-CVVT) OVERVIEW

A conventional Continuous Variable Valve Timing (CVVT) system provides more efficient engine operation by changing valve timing and valve overlap depending on engine load. An Electric Continuous Variable Valve Timing (E-CVVT) system replaces the hydraulics and Oil Control Valve (OCV) solenoid used in the conventional CVVT with a DC motor. Quicker responses and larger operating angles are gained by using the electric CVVT versus hydraulics. Because E-CVVT is not dependent on oil pressure it can operate regardless of oil pressure build up. This helps to reduce exhaust gases at cold start.

On 2016MY Sorento (UMa) with 2.4L GDI and 2.0L Turbo engines; the E-CVVT is only applied to the intake camshaft, a brush equipped DC motor is inside the E-CVVT unit. A benefit of using DC motor, it allows for the operating angle to double from 45° to 90° compared to that of hydraulic CVVT. This motor only operates when cam phase angle changes are required. An E-CVVT relay, located in the PCB block (E/R Junction block), provides battery power to the PCM to control E-CVVT motor Pulse Width Modulation (PWM). The Conventional CVVT is currently used on the exhaust camshaft.

Below are some maintenance precautions:

• The E-CVVT cover must be removed and reinstalled separate from the timing cover.

• The E-CVVT cover seal, E-CVVT cover plug and E-CVVT motor plug prevent oil from seeping into the motor brush. These parts must be replaced on reassembly.

• SST p/n 09243-C1000 must be used to align centers of camshaft, E-CVVT unit and cover. The same tool is also used to install the motor plug.

• In event of failure, E-CVVT is automatically maintained in a maximum retard state by cam torque.

• When an E-CVVT unit is replaced or remounted an E-CVVT learned value erase procedure must be performed using GDS/KDS Software Management. E-CVVT performs an automatic position relearn.
