DSC cannot transmit/receive at the CAN
Possible cause(s) of fault:
- The CAN bus is defective (interruption, short circuit, plug-in connection)
- Another control unit on the CAN is causing this fault entry.
- The CAN module in the control unit for traction control is defective
Storage condition(s):
- The control unit for traction control continuously monitors whether transmission and reception are possible on the bus. If this is not possible several times in succession or permanently, this fault is set.
Troubleshooting procedure:
- Check of the fault code memories of other control units as to whether the faults entered there indicate a certain control unit or the CAN.
- Check of the bus lines
- If the CAN and the other control units are OK, the control unit for traction control must be replaced.
Note
- Renewing the control unit, see Service functions
