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:
- The control panel reported that a control lost function.
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.
