Ignition System: Description and Operation

Ignition System

• The engine control module 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 DTC during some tests. Therefore after completing all checks and repairs the DTC memory must be checked and if necessary erased.

• 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 engine control module (ECM). DTC memory must then be checked and if necessary, control module must be adapted.
