General Information

A message (ID number) is sent out on the CAN network at regular intervals from the Central electronic module (CEM). Other control modules listen for this message, typically at the following occasions:

When the control module has been without power.
After downloading the software.
Certain control modules listen for the message each time the ignition is switched off.

This diagnostic trouble code indicates that the control module has not received any identity number, or that the expected number is not correct. The diagnostic trouble code is set if the control module has not received correct identity number within a certain time interval, from and including the occurrence of any of the above. The time interval is 4.5 or 7 seconds long, depending on control module.

Corrective actions

If this type of diagnostic trouble code is stored in the control module that set the diagnostic trouble code, this indicates incorrect configuration-id in the control module. A possible cause is that a used control module has been installed in the car without loading software. Solve the problem by reloading the software in the control module.
In some cases, the DTC can also be generated due to an open-circuit or other interference on the CAN wiring between the control module and the Central electronic module (CEM). These types of faults must, however, be first detected by other DTCs. Fault trace starting from these DTCs.

Other information

Go to the software manager and program the control module with the latest software.
