Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
The driver/passenger door module (DDM/PDM) both sends and receives information via a standardized serial communication method - LIN (Local Interconnect Network). The Driver door module (DDM) communicates with the control panel in the driver door via LIN-communication.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Signal missing for a period longer than 350 ms.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition position II or engine running.

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 communication cable.
- 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.
