Fault-Tracing Information

Fault-tracing

Checking the wiring and terminals
A diagnostic trouble code for CAN communication can also be generated in the Central Electronic Module (CEM). In some instances, the diagnostic trouble code is generated in other affected control modules. This diagnostic trouble code shall not be cleared until the trouble code in the central electronic module (CEM) and in other affected control modules has been remedied and cleared.
Therefore, first read the diagnostic trouble codes in the Central Electronic Module (CEM) and other affected control modules, perform fault tracing and remedy as necessary. If no diagnostic trouble codes (DTCs) are stored, fault-trace the controller area network (CAN) as follows. This diagnostic trouble code (DTC) can then be erased. Also check that the cables do not lie too close to a source of disturbance, such as cellular phones etc.
For further information on this diagnostic trouble code, see Diagnostic trouble code (DTC) information.
