Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
The control module left rear door/right rear door (LDM/RDM) supplies the LED indicator for lock status (locked/unlocked) in the central locking button, and supplies the driver's door/passenger door (DDM/PDM) control module with information.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Voltage on the signal cable is too low.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Control module supplied with power.
- The control module attempts to light the LED indicator.

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
- The control module stops powering the LED indicator.

Possible source
- Short-circuit to ground in the power supply cable.
- Moisture and/or oxidation in terminals.

Fault symptom[s]
