Fault-Tracing Information

Fault-tracing

Checking communication with the gear selector module (GSM)




- Ignition on.
- Read off the position of the gear selector.
- Depress the brake pedal. Move the gear selector to the position for manual shifting and check that the status changes.
- Then move the gearshift selector toward both + and -, and check that the value has been updated in the driver information module's display window.
If the value is updated in the driver information module display, the fault is intermittent. That is to say, it occurred earlier but is not active right now.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit fault-tracing

No - Attempt New Test

Checking the components and wiring




- Ignition off.
Check connector (16 pin) for the transmission control module (TCM) and gear selector module (GSM). Check for contact resistance and oxidation.
Check the communication cable (LIN) for intermittent short circuits or open circuit.
Take readings between:
- Transmission control module (TCM) terminal #A7 and gear selector module (GSM) terminal #2.
Check for open circuit.
Take readings between:
- Transmission control module (TCM) terminal #A16 and gear selector module (GSM) terminal #1.

Hint: The gear selector module (GSM) is supplied power from the transmission control module (TCM).

Check the ground cable. Check for loose connections, contact resistance and oxidation. Check for an open-circuit.
Take readings between:
- Gear selector module (GSM) terminal #6 and the ground connection.
If no fault can be found, replace the gear selector module (GSM).
