Diagnostic depth
Detection
The CAN-message contains a sequence counter to ensure data consistency. The software compares the expected counter value to the counter vale contained in the message. A fault code is set if the counter values don't match for a specified amount of messages.
Possible cause
Mismatch in communication between the EBS and TMS. Possible reasons for the fault are faulty EBS software, disturbances on the CAN bus or high load on the CAN bus.
