Hva betyr feilkoden?
The ECM has registered an internal fault in how it converts analogue signals into digital values (the A/D converter). The code is set, and engine speed and torque are limited.
Mulige årsaker
- Damaged engine control module (ECM)
Hva du kan gjøre
- 1Clear the code and test drive the car to see whether it returns
- 2For a permanent fault the engine control module is replaced, which a workshop does
Symptomer du kan merke4
- Low maximum engine speed
- Cruise control does not work at all
- Uneven idle
- Malfunction indicator lamp lit
Hva feilen kan påvirke1
- Engine speed and torque are limited to a calculated reasonable value
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
