Hva betyr feilkoden?
The ECM monitors the battery voltage and checks it against the reference that the central electronic module (CEM) broadcasts on CAN. The code is set when the voltage the ECM measures is lower than the value sent over CAN. The fault may be caused by contact resistance, oxidation or a poor connection in the connections.
Mulige årsaker
- Contact resistance, oxidation or poor contact in the connections
Hva du kan gjøre
- 1Check that the fuses are intact.
- 2Check the battery and its connections, and the connections to the engine control module. Look for oxidation, play and loose connectors.
- 3If the code returns, have a workshop read out and troubleshoot the voltage with diagnostic equipment, as this requires measurement.
Symptomer du kan merke1
- No noticeable symptoms for the driver
