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 and ignition system, see COMPONENT LOCATIONS, OVERVIEW .
The engine control module is equipped with On Board Diagnostic (OBD).
Components marked with * are checked via the On Board Diagnostic (OBD), see DIAGNOSTIC TROUBLE CODE (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 trouble code. Therefore after completing all checks and repairs the Diagnostic Trouble Code (DTC) memory must be checked and, if necessary, erased. See DIAGNOSTIC TROUBLE CODE (DTC) MEMORY .
