Hva betyr feilkoden?
The engine control module takes its vehicle configuration from the central electronic module (CEM), which keeps the number of software versions down. The code is set when the engine control module finds that a parameter sent by the CEM is incorrect. This typically happens when a control module or function has been added or removed without the configuration being updated, and a default value is then used for the faulty parameter.
Mulige årsaker
- A control module or function has been added to or removed from the vehicle without the configuration being updated
Hva du kan gjøre
- 1Consider whether a control module or function has recently been replaced, added or removed on the car; that is the most likely cause of this code
- 2Clear the code once the change has been made correctly and road test the car to see whether it returns
- 3If something has been changed on the car, have a workshop update the vehicle configuration, since this requires programming
Symptomer du kan merke1
- No noticeable symptoms for the driver
Hva feilen kan påvirke1
- A default value is used for the faulty parameter
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
