DEM-U040168: Invalid Data Received From Engine Control Module. Algorithm Based Failures. Event Information (2007-2008): Fault-Tracing: Information: Overview

There is no fault-tracing for this diagnostic fault code (DTC).

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.

For further information on this diagnostic trouble code, see Diagnostic trouble code (DTC) information.
