Communication fault indicating the primary vehicle controller has received corrupted or implausible data frames from Lighting Driver Control Module D, which typically manages a specific exterior lighting zone such as a matrix headlight segment or auxiliary lamp bank. The receiving module detects that the message structure is valid but the content values fall outside acceptable operational parameters, suggesting the lighting driver is malfunctioning or the data bus is compromised.
The module responsible for driving the specific lamp bank has developed internal logic corruption, memory faults, or power driver failures that cause it to transmit garbled status messages onto the network bus.
Corroded, backed-out, or moisture-intruded pins in the module's connector, along with chafed or shorted network communication lines between the driver and the gateway, corrupt the data transmission.
High resistance in power feeds or ground paths causes voltage drops during high-current lighting operation, resulting in erratic microcontroller behavior and invalid data frames.
Excessive resistance, short-to-ground, or electromagnetic interference on the LIN or CAN bus segment shared by the lighting module alters message integrity before it reaches the receiving controller.
Rarely, a failed gateway module or missing bus termination resistor corrupts message timing for multiple modules; this is unlikely if only Module D reports invalid data.
No. This code indicates invalid data received from the lighting module, not a failure of the receiving computer. PCM replacement is almost never the solution and will not resolve the root cause; focus on the lighting driver module and its wiring first.
You may drive briefly, but exterior lighting on the affected circuit may be inoperative or behave unpredictably, creating a safety hazard at night. Repairs should be prioritized before driving in low-light conditions.
It designates the fourth lighting driver in a multi-module architecture, often corresponding to a specific headlight unit, taillight assembly, or auxiliary lamp zone. Consult manufacturer documentation to map 'D' to a physical location on the vehicle.
No. The code will likely return immediately if the underlying communication fault persists. Clearing only resets the detection counter; physical repair of the module or wiring is required to permanently resolve the issue.
