Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
The Driver/Passenger door module (DDM/PDM) receives information about current vehicle configuration from the central electronic module (CEM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Vehicle configuration from central electronic module (CEM) is lost.
- Incorrect value lasts longer than 30 seconds.
The control module automatically erases DTCs when it receives a message about the vehicle configuration from the Central electronic module (CEM).
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Control module supplied with power.

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
- Open-circuit in the control area network (CAN).
- Short-circuit to ground in the communication cable.
- Short-circuit to supply voltage in the communication cable.
- Contact resistance, oxidation or poor contact in connections.
