The engine control module (ECM) has registered an internal fault in itself. The fault is intermittent, meaning it occurred on an earlier occasion, but when the module checked again it was no longer present. The code is stored in the engine control module.
Mögliche Ursachen
- Signal fault inside the engine control module
- Defective engine control module
Was Sie tun können
