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.
