Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information TCM-P085A00

Condition
The transmission control moduel (TCM) and gear selector module (GSM) communicate with each other in a network via standardized serial communication - local interconnect network (LIN). The control modules transmit and receive information.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The signal from the Transmission control module (TCM) is incorrect.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition on.

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
- Manual gear shift position (+/-) function is blocked.

Possible source
- Interference on the communication lead (LIN) between the gear selector module (GSM) and the transmission control module (TCM).
- Internal fault in gear selector module (GSM).

Fault symptom[s]
- Gauges/Gear indicator does not work
- Text window and warning symbol/Yellow symbol and text message
- Automatic transmission/No manual gear shift
