This code indicates a software mismatch between the engine control module and the glow plug control module. It prevents proper communication regarding glow plug operation, typically occurring after module replacement or incomplete programming updates. The vehicle may limit engine performance until the modules are synchronized.
One or both control modules require a software update to match current calibration standards.
Internal failure within the glow plug controller prevents proper data exchange with the engine computer.
Low voltage or power loss can corrupt module memory, leading to perceived software mismatches.
Damaged communication wires can corrupt data signals, mimicking a software incompatibility.
High resistance in module grounds disrupts stable communication required for software handshake.
Internal failure of the engine computer is rare and should only be considered after all other options are exhausted.
Rarely. This usually indicates a software update is needed or the glow plug module itself requires replacement.
It is not recommended, especially in cold weather, as starting performance may be compromised.
No, the software incompatibility will return until the modules are properly synchronized or replaced.
Yes, replacing a module without programming it to the vehicle often triggers this code.
