Diagnostic Trouble Codes (DTCS)

A diagnostic trouble code (DTC) is stored if the control modules detect a fault. The Driver door module (DDM) and Passenger door module (PDM) can store up to 10 diagnostic trouble codes (DTCs) each.

If a fault disappears for any reason after the diagnostic trouble code (DTC) has been permanently stored in the control module, information about the fault remains in the control module.
