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
