Control units
Check with SDP3 whether any of the control units has a different chassis number and if so reprogram the control unit. Click here for "More information".Check through other fault codes to see if there is a communication error between any one of the individual control units and the coordinator. If this is the case, check the circuit for the affected control unit power supply (30) and its activation signal (15). If communication with several control units has been interrupted, check wiring and connectors for the affected CAN bus.

Diagnostic depth
The coordinator has identified deviant information from one or more of the control units connected to the CAN network.
The fault may be due to: One or more of the vehicle control units has a chassis number programmed which does not correspond to the chassis number programmed by the coordinator. The control unit concerned may be incorrectly programmed or not programmed.Short circuit or open circuit in the voltage supply circuit for one of the vehicle's control units.Short circuit or open circuit on one of the CAN buses.
