Ignition System

Ignition System

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

• After completing the work, check the Engine Control Module (ECM) Diagnostic Trouble Code (DTC) memory. Erase all DTC entries which may have been caused by tests and repairs. If DTC memory was erased, generate a readiness code. Refer to "Guided Function" in the vehicle diagnostic tester.

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