Ignition System: Description and Operation

General

NOTE:
- The battery must only be disconnected and connected with the ignition switched off. The Engine Control Module (ECM) can otherwise be damaged.
- For the electric components to work properly, a voltage of at least 12.7 V is required.
- It is possible that the control module will recognize a malfunction and store a DTC during some tests. After completing all tests and repairs, the Diagnostic Trouble Code (DTC) memory should therefore be checked and erased 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 Engine Control Module (ECM). The DTC memory must then be checked and if necessary, the control module must be adapted.
