DME/DDE (Funtional Tests)

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 module on the CAN is causing this fault entry.
- The CAN module in the control module for traction control is defective

Storage condition(s):
- The control module 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 memories of other control modules as to whether the faults entered there indicate a certain control module or the CAN.
- Check of the bus lines
- If the CAN and the other control modules are OK, the control module for traction control must be replaced.

NOTE: Renewing the control module, see Service functions
