Diagnostic Trouble Code (DTC) Information TCM-E003

Condition

The Transmission control module (TCM) compares its configuration ID with the signal configuration the central electronic module (CEM) transmits on the CAN network.

The diagnostic trouble code (DTC) is stored if the control module detects that:

The configurations IDs do not correspond.
Communication with Central electronic module (CEM) is lost.

NOTE:

In the event of an open-circuit in both the controller area network (CAN) cables, it is not possible to communicate with the transmission control module (TCM). Therefore it will only be possible to read off the fault if it is intermittent. When the diagnostic trouble code is generated, the control module answers to the diagnostic commands, however, the normal CAN-communication does not work ("Expulsion-mode").

Substitute Value

Auxiliary program Emergency mode 1 in the transmission control module (TCM) has started.
HINT: EMERGENCY MODE IN THE EVENT OF A FAULT

Possible Source

Incorrect CAN-configuration ID (current transmission control module (TCM) is not suited to the vehicle, for example, a used control module with different software/hardware).
Open-circuit in the CAN cables between the control module and the Central Electronic Module (CEM).
