Ignition System: Description and Operation

Ignition System

• The Engine Control Module (ECM) is equipped with On Board Diagnostics (OBD).

• For the electric components to work properly, a voltage of at least 11.5 Volts is required.

• It is possible that the control module will recognize a malfunction and store a Diagnostic Trouble Code (DTC) during some tests. After completing all checks and repairs, check the DTC memory and erase the memory, if necessary.

• If the engine only starts briefly and then turns off again after troubleshooting, repair or checking of the components, it may be that the immobilizer is blocking the ECM. DTC memory must then be checked and if necessary, control module must be adapted.
