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 Transmission Control Module (TCM) (J217) fuse 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 selector lever must be in the "P" position.

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

• Ignition switched off.

Test procedure

- Perform a preliminary check to verify the customers complaint. Refer to => [ Preliminary Check ] Preliminary Check.

Start diagnosis

- 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 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. Refer to Automatic Transmissions, Repair Group 38.

If the specified values are obtained:

Checking wiring

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

- Install the test box. Install the Adapter F/VAG1598 (VAG1598/22).

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

- Remove the Transmission Control Module (TCM) ( J217). Refer to => [ Transmission Control Module, Replacing ] Service and Repair.

- Using a multimeter, check the Solenoid Valve electrical harness connector terminals to the Transmission Control Module (TCM) (J217) electrical harness connector T52 terminals for resistance.









Specified value: 1.5 ohms Max.

If the specification was not obtained:

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

- If necessary, repair the faulty wiring connection.

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

- Replace the faulty Solenoid Valve.

- Erase the DTC memory. Refer to => [ Diagnostic Mode 04 - Erase DTC Memory ] Diagnostic Mode 04 - Erase DTC Memory.

- Perform a road test to verify repair.

If the DTC does not return:

Repair complete, Generate readiness code. Refer to => [ Readiness Code, Setting ] Readiness Code, Setting.

- End of diagnosis.

If the DTC does return and no malfunction is detected in the wiring and resistance was OK:

- Replace the Transmission Control Module (TCM) ( J217). Refer to => [ Transmission Control Module, Replacing ] Service and Repair.

- Assembly is performed in the reverse of the removal.

Final procedures

1. Check the DTC memory. Refer to => [ 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. If the DTC memory was erased, generate readiness code. Refer to => [ Readiness Code, Setting ] Readiness Code, Setting.

End of diagnosis.
