Disconnect the Transmission Input Speed (RPM) Sensor G182 electrical harness connector - 1 -.
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 wiring

If the manufacturers test box is being used, perform the following step.

Install the Adapter F/VAG1598 (68 Pin) VAG1598/22. Refer to
- for 5 SPD. AUTOMATIC TRANSMISSION 01V
- for 5 SPD. AUTOMATIC TRANSMISSION 01V FRONT AND ALL WHEEL DRIVE - INTERNAL COMPONENTS, SERVICING
- for 6 SPD. AUTOMATIC TRANSMISSION 09L ALL WHEEL DRIVE
.

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 (TCM) J217, Replacing .

Specified value: 1.5 Ω 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 is found in the wiring and the resistance was not OK:

Replace the Transmission Input Speed (RPM) Sensor G182. Refer to →
- for 5 SPD. AUTOMATIC TRANSMISSION 01V
- for 5 SPD. AUTOMATIC TRANSMISSION 01V FRONT AND ALL WHEEL DRIVE - INTERNAL COMPONENTS, SERVICING
- for 6 SPD. AUTOMATIC TRANSMISSION 09L ALL WHEEL DRIVE
.

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

Erase the DTC memory. Refer to → Diagnostic Mode 04 - Reset/Delete Diagnostic Data
Perform a road test to verify repair.

If the DTC does not return:

Repair complete, Generate readiness code. Refer to → Readiness Code Description .

End diagnosis.

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

Replace the Transmission Control Module (TCM) J217. Refer to → Transmission Control Module (TCM) J217, Replacing .

Final procedures

Check the DTC memory.
If necessary, erase the DTC memory. Refer to Diagnostic Mode 04 - Reset/Delete Diagnostic Data .
If the DTC memory was erased, generate readiness code. Refer to Readiness Code Description .
