Hva betyr feilkoden?
The control module has recorded an internal fault in its own knock control circuit, so the fault is not in any sensor or in the wiring. It may be a single occurrence or a fault that is still present. The engine warning lamp may come on, and ignition timing is pulled back to protect the engine until the control module is repaired.
Mulige årsaker
- Damaged control module
Hva du kan gjøre
- 1Clear the fault code, drive the car briefly and see whether the code returns
- 2Check the battery condition and that the cables and ground connections are secure, since interference at start-up can cause temporary faults
- 3Have a workshop replace the control module if the fault returns or remains
Symptomer du kan merke2
- Poor performance
- Engine warning lamp lit
Hva feilen kan påvirke1
- Ignition advance is pulled back to protect the engine
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
