Diagnostic Trouble Code (DTC) Information ECM-710C

Condition 

The engine control module (ECM) contains a code for the immobilizer which is unique to each car. Before the engine can be started, the immobilizer code is checked to ensure that it corresponds to both the central electronic module (CEM) and the engine control module (ECM).

The diagnostic trouble code (DTC) will be stored if the engine control module (ECM) is not programmed or if an internal fault is detected in the engine control module (ECM).

The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.

Substitute Value 

None.

Possible Source 

• The engine control module (ECM) is not programmed and has no code for the immobilizer
• Damaged engine control module (ECM).

Fault symptom[s] 

• The starter motor turns but the engine does not start.
