Diagnostic Trouble Code (DTC) Information TCM-P086013
Condition
The transmission control module (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:
- No signal from the Gear selector module (GSM).
The control module's test for the diagnostic trouble code (DTC) starts in the event of:

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.
