Ignition System: Service Precautions

Ignition System

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

• It is possible that the control module will recognize a malfunction and store a Diagnostic Trouble Code (DTC) during some tests. After completing all tests and repairs, the DTC memory should therefore be checked and erased if necessary. Refer to "Guided Functions" in the vehicle diagnostic tester.

• If the engine only starts briefly and then turns off again after troubleshooting, repairs or checking of the components, it may be that the immobilizer is blocking the Engine Control Module (ECM). The ECM must then be adapted if necessary. Refer to "Guided Functions" in the vehicle diagnostic tester.
