General Notes on Ignition System




General Notes on Ignition System
- Only the components which specifically relate to the ignition system are dealt with here. For the other components of the injection system, refer to appropriate information.
- Components marked with * are checked via the On Board Diagnostic, checking and erasing DTC memory.
- For trouble-free operation of the electrical components a voltage of at least 11.5 V is necessary.
- During some checks it is possible that the control module will recognize and store a malfunction. Therefore after completing all checks and repairs the DTC memory must be checked and if necessary erased.
- If the engine starts, runs for a short period and then stops, after troubleshooting, repairs or component tests, then the fault may lie with the immobilizer which is blocking the engine control module. The DTC memory must be checked and if necessary the control module adapted.
