Signal Missing

Signal missing

Information
The immobilizer function is integrated in the central electronic module (CEM).
This diagnostic trouble code (DTC) may be due to missing CAN communication. If there is a diagnostic trouble code (DTC) stored in the central electronic module (CEM) fault trace accordingly.

Note! An unprogrammed central electronic module (CEM) does not have a code for the immobilizer, which can result in this diagnostic trouble code (DTC) being stored.

If no diagnostic trouble codes (DTCs) are stored in the central electronic module (CEM), try a new central electronic module (CEM).
