Transmission Position Sensor/Switch: Testing and Inspection






Calibration of position sensor

Note! Calibration of the integral position sensor in the transmission control module (TCM) must be carried out when the control module is replaced or has been removed from the automatic transmission.




- Ignition on
- Place the gear selector lever in neutral position (N).
Activate calibration of the position sensor in the transmission control module (TCM) by clicking on the VCT2000 symbol.

Caution! During calibration, it is important that the gear selector module (GSM), gear selector assembly and linkage are free of faults.
