Ignition System
- For trouble free operation of the electrical components a voltage of at least 11.5 volt is necessary.
- Check the Engine Control Module (ECM) Diagnostic Trouble Code (DTC) memory after completing the procedure. Erase all DTC entries which may have been caused by tests and repairs. If the DTC memory was erased, the readiness code must be generated again. Refer to "Guided Fault Finding" 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 ECM. The ECM may have to be adapted. Refer to "Guided Functions" in the vehicle diagnostic tester.
