Hva betyr feilkoden?
The control module continuously receives information from several other control modules over HS-CAN. The code is set when communication with the DC/DC converter (DCDC) has stopped. The fault usually lies in the sending module or in the wiring on HS-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 read the fault codes in the DC/DC converter and remedy them first
- 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
