Hva betyr feilkoden?
The additive dosing module (ADM) sits on the high-speed CAN network and has registered a serious disturbance there. It has therefore switched off its communication (bus-off) and will not restart until the power supply is cut and reconnected. In practice the fault is only readable when it is intermittent.
Mulige årsaker
- Short circuit between the CAN wires
- Open circuit in one of the CAN wires
- Internal fault in the control module
- Internal fault in another control module on the same part of the CAN network
Hva du kan gjøre
- 1Read the codes in the central electronic module (CEM) first, since it monitors the voltage on the CAN wires
- 2Check the battery and its terminals so the voltage is stable
- 3With diagnostic equipment check the CAN network for breaks and shorts
- 4Do not replace the central electronic module for a CAN fault unless fault-finding shows it is faulty
- 5Clear the codes after the repair and check that they do not return
Symptomer du kan merke1
- No clear symptoms for the driver
Hva feilen kan påvirke2
- The module switches its communication off (bus-off)
- It stays off until the power supply is cut, then tries to communicate again at the next power-up
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
