Additional Notes on Ignition System



General Notes On Ignition System

- The engine control module is equipped with On Board Diagnostic (OBD).
- For trouble-free operation of electrical components, a voltage of at least 11.5 V is necessary.
- During some checks, it is possible that the control module will detect and store a fault (DTC). Therefore, after completing all tests and repairs, read the Diagnostic Trouble Code (DTC) memory and erase it if necessary.
- If the engine runs only for a short period of time after performing fault finding, repairs or component tests and then stalls, it could be that the immobilizer is blocking the engine control module. In such cases the Diagnostic Trouble Code (DTC) memory must be read and the control module adapted, if necessary.
