Hva betyr feilkoden?
On the V40 this code is event controlled and is intended as information. It does not mean there is a fault in the module where it is stored. It is set when the central electronic module (CEM) has restarted too many times during engine start, which can happen when battery voltage is low.
Mulige årsaker
- Low battery voltage in the car when the engine starts
Hva du kan gjøre
- 1Start with the battery: check that it is charged, since low battery voltage at start is the cause of this code
- 2Check that the battery terminals and earth connections are tight and free from corrosion
- 3Road test the car after the battery check and see whether the symptoms have gone
- 4If the symptoms remain even with a healthy battery, have a workshop read the module codes with diagnostic equipment
Symptomer du kan merke5
- The engine does not start, or cranks without starting
- The car performs poorly and lacks power, especially when pulling away
- The car hesitates, surges or feels jerky when driving
- Cruise control cannot be engaged
- Gauges show wrong readings or do not work
Hva feilen kan påvirke1
- The functions of the central electronic module (CEM) are restricted
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
