This diagnostic trouble code indicates that a control module is receiving implausible or invalid data from the Front Lighting Control Module over the vehicle communication network. It suggests a communication breakdown or data corruption rather than a specific mechanical failure within the engine itself. This issue typically affects lighting systems and network stability.
Physical damage to the harness or corrosion at the connector prevents valid data transmission.
The module itself may be malfunctioning and sending erratic or invalid signals over the network.
Insufficient voltage supply can cause modules to reset or transmit corrupted data packets.
Damaged CAN bus wires or electromagnetic interference disrupts signal integrity between modules.
Poor grounding creates voltage drops that lead to data errors across the vehicle network.
While rare, the receiving module may have an internal processing error preventing valid data recognition.
No, this code points to data from the lighting module, and replacing the engine computer is rarely the correct repair.
Caution is advised as exterior lighting may not function correctly, creating a safety hazard at night.
Unlikely, as this indicates a persistent data invalidity that usually returns once the system cycles.
Common causes include voltage spikes, ground faults, or a failing module sending erratic signals.
