Diagnostic Trouble Code (DTC) Information TCM-P081442
Condition
The Gear selector module (GSM) communicates with the Transmission control module (TCM) via an internal network, Local Interconnect Network (LIN). The Gear selector module (GSM) manages, among other things, the shift-lock function, manual shifting (+/-) and indication for the selected gear position on the gear selector's top panel.
The diagnostic trouble code is stored if the control module detects:
- Internal fault in gear selector module (GSM).
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.
NOTE:
The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
Substitute Value
- None.
Possible Source
- Internal fault in gear selector module (GSM).
Fault symptom[s]
- No manual gear shift
- Gear selector indicator does not function
