This diagnostic trouble code indicates a network communication error where invalid or implausible data is received from a specific door control module. It usually signifies a wiring fault in the door jamb or a malfunction within the door module itself rather than a major computer failure. Repair typically involves inspecting harness integrity and connector conditions.
Wires flex repeatedly when the door opens and closes, leading to metal fatigue and breaks.
Moisture intrusion or vibration can cause poor electrical contact at the module interface.
The electronic components within the door module itself may have failed due to age or heat.
Insufficient power supply can cause network communication errors across multiple modules.
The module firmware may contain errors that require a calibration update.
While rare, the main controller managing the network could be malfunctioning.
No, this code relates to the door module network, and replacing the PCM is rarely the solution.
Yes, but security features or convenience functions like locking may be compromised.
Wires in the door jamb flex every time the door opens, leading to eventual metal fatigue and breaks.
It may clear the code temporarily, but the underlying wiring or hardware fault will likely return.
