Hva betyr feilkoden?
The engine control module (ECM) runs internal tests on its processor, software and memory, and the code is set when one of them registers a fault. The fault can lie in the control module itself, and it is sometimes set together with other codes. While the fault is active the throttle and cruise control are limited.
Mulige årsaker
- Defective engine control module
- The code can be set together with other codes, which should then also be read out
Hva du kan gjøre
- 1Read the other codes stored at the same time, since this code can be set together with them
- 2Clear the code and road test the car to see whether it comes back
- 3If the fault remains, have a workshop replace the control module and program the new one, since it is supplied without software
Symptomer du kan merke4
- The accelerator pedal is ignored when braking
- Cruise control cannot be engaged
- Uneven idle
- The electronic throttle system warning lamp is on
Hva feilen kan påvirke3
- The throttle follows the accelerator pedal position directly, and fuel cut-off follows the pedal position
- Engine speed is regulated by switching off the injectors one at a time, so idle may feel very uneven
- Cruise control is switched off during the driving cycle in which the fault was detected, and it is available again at the next start if the fault is no longer present
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
