U200A88

Communication error on Display Subnet

Bus off

No communication is possible to the Secondary Information Display (SID). The SID can not receive any data on the CAN-network. The SID keep the last recevied VehicleMode

– CAN High Short Circuit to ground

– CAN High short circuit to CAN Low

– Open circuit CAN High

– Open Circuit CAN Low

– Connector damaged

– Connector disconnected

– Transciever damaged

Diagnostic Service 14. No additional action is needed.

Investigate root-cause:

– CAN-network error => Fix problem.

– CAN-cable => Fix problem. Transceiver failure => Replace ECU
