Solenoid Valves in Valve Body, Checking

Solenoid Valves in Valve Body, Checking

This procedure is used to diagnose all Solenoid Valves in the valve body.

Special tools, testers and auxiliary items required

• Multimeter

• Wiring diagram

Requirements

• The Solenoid Valve fuses OK.

• The battery voltage must be at least 12.5 Volts.

• All electrical consumers must be switched off.

• The parking brake must be engaged.

• The elector lever must be in the "P" position.

• The Ground (GND) connections to transmission must be OK.

Procedure

- Disconnect the Solenoid Valve electrical harness connector - 2 -.





- Check the electrical harness connector for damage, corrosion, loose or broken terminals.

- Repair any damage found to the electrical harness connector.

If the electrical harness connector is not OK:

- Repair the malfunction.

If the electrical harness connector is OK:

Checking resistance

- Using a multimeter, check the Solenoid Valve terminals 1 to 2 at the Solenoid Valve electrical harness connector for resistance.









If any of the specified values are not obtained:

- Replace the faulty Solenoid Valve.

If the specified values are obtained:

Checking wiring

If the manufacturers test box is being used. Perform the following step.

- Install the test box.

If the manufacturers test box is not being used. Perform the following step.

- Remove the Transmission Control Module (TCM) (J217).

- Using a multimeter, check the Solenoid Valve electrical harness connector terminals to theTransmission Control Module (TCM) (J217) electrical harness connector T52 terminals for an open circuit.









Specified value: 1.5 ohms Max.

If the specified value was not obtained:

- Check the wiring for a short circuit to each other, Battery (+), and Ground (GND).

- If necessary, repair the faulty wiring connection.

If no malfunction is found in the wiring and the resistance was not OK:

- Replace the faulty Solenoid Valve.

If no malfunction is found in the wiring and the resistance was OK:

- Replace the Transmission Control Module (TCM) (J217).

Final procedures

1. Check the DTC memory. --> [ Diagnostic Mode 03 - Read DTC Memory ] Diagnostic Mode 03 - Read DTC Memory.

2. If necessary, erase DTC memory of the Transmission Control Module (TCM) (J217). --> [ Diagnostic Mode 04 - Erase DTC Memory ] Diagnostic Mode 04 - Erase DTC Memory.

3. Generate readiness code. --> [ Readiness Code ] Monitors, Trips, Drive Cycles and Readiness Codes.
