Counter error on CAN-message Powertrain Control 5
â–¶ How to fix
Check if any Timeout or Checksum fault codes are present. If yes, follow the actions for those fault codes, otherwise replace the BCI. If that doesn't help, replace the TMS.
What you'll see
No driver-visible symptom recorded.
System reaction
No system-reaction text recorded.
Diagnostic depth
Detection
The PTC5 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 BCI and TMS. Possible reasons for the fault are a high load on the CAN bus or faulty BCI software.
