Hva betyr feilkoden?
The control module continuously receives information from several other control modules over Sensor-CAN. The code is set when communication with the inverter electric rear axle drive module (IEM) has stopped. The fault usually lies in the sending module or in the connectors and wires on Sensor-CAN.
Mulige årsaker
- The fault probably lies in the sending control module
- Contact resistance or oxidation in the connectors
- Damaged communication wiring on the CAN network
Hva du kan gjøre
- 1Read and note the fault code, clear it and road test to check whether it returns
- 2Have a workshop check the Sensor-CAN connectors and wires for damage
- 3The high voltage system should only be handled by qualified personnel, so have a workshop carry out all work on the battery and other high voltage parts
Symptomer du kan merke1
- No noticeable symptoms for the driver
