BUS OFF

0C CAN BUS OFF

Possible cause(s) of fault:
- The data transmission on the CAN bus is disrupted.

Storage condition(s):
- The CAN status is monitored continuously. Continuing CAN bus disturbances lead to the status BUS OFF. After the fault has been rectified, the latent heat accumulator becomes active again of its own accord.

Troubleshooting procedure:
- Have similar faults been entered in other control modules?
- Yes: repair CAN
- No: if the fault has been entered a number of times, the steering angle sensor must be replaced; otherwise, ignore the fault.

NOTE: After replacing the steering angle sensor, it must first be coded and then calibrated using the ABS/DSC diagnostic program.
