    What does this fault code mean?

    The gear selector control module (GSM) has registered that the signal for the gear selector lock (shift-lock) is high even though it is being driven low. This can be caused by a fault in the gear selector control module, or a short to voltage in the wire to the lock solenoid.

    Possible causes

    • Internal fault in the gear selector control module (GSM)
    • Contact resistance, corrosion or a loose connection in the connections
    • Short to voltage in the signal wire to the shift-lock solenoid

    What you can do

    1. 1Test the gear selector in position P: without the brake pedal it should not move, and with the brake pedal pressed it should move
    2. 2Check the connectors at the gear selector for looseness, corrosion and damage
    3. 3Use a multimeter to check that the wire to the shift-lock solenoid has no contact with battery positive voltage
    4. 4If the fault remains, have a workshop check the gear selector

    Symptoms you may notice3

    • Manual shifting does not work
    • The gear indicator does not work
    • Yellow warning symbol and text message in the display

    General guidance for car owners. Diagnosis on the car can point to a different cause.
