Hva betyr feilkoden?
The additive dosing module (ADM) cannot make contact with the engine control module (ECM). This is a general fault code that does not say which type of fault it is. It can only be read out if the fault is intermittent, because the module cannot communicate while the fault is active. The fault may lie in the data network or in the engine control module.
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 engine control module and in the central electronic module, since the fault may be linked to them
- 2Check the battery and its terminals so the voltage is stable
- 3With diagnostic equipment check the data network and the connectors between the modules
- 4Do not replace the engine or central electronic module until the data network has been investigated
- 5Clear the code only once the cause is fixed, and check that it does 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
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
