Shift Solenoid: Testing and Inspection

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.

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.

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.







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







Specified value: 1.5 Ohms Max.

If the specification 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 was found in the wiring and the resistance was not OK:
- Replace the faulty Solenoid Valve.
- Erase the 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. Monitors, Trips, Drive Cycles and Readiness Codes
- End 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.
- Assembly is performed in the reverse of the removal.

Final procedures
1. Check the DTC memory. Diagnostic Mode 03 - Read DTC Memory
2. If necessary, erase DTC memory of the Transmission Control Module (TCM) J217.
3. Generate readiness code.

End diagnosis.
