Ignition System: Description and Operation

Ignition System General Information

• For trouble-free operation of the electrical components a voltage of at least 11.5 V is necessary.

• It is possible that the control module will recognize a malfunction and store a DTC during some tests. After completing all tests and repairs, DTC memory should therefore be checked and erased if necessary => [ Engine Control Module DTC Memory, Checking and Erasing ] Engine Control Module DTC Memory, Checking and Erasing.

• If the engine only starts briefly and then turns off again after troubleshooting, repairing or checking components: the anti-theft immobilizer may be blocking the engine control module. Adapt the engine control module, => Vehicle Diagnosis Tester "Guided Functions".
