General information about the ignition system
t  The engine control unit has a self-diagnosis capability.
t  A voltage of at least 11.5 V is required for proper operation of the electrical components.
t  In some tests the control unit may detect and store an error. The event memory should therefore be interrogated and (if necessary) erased after completing the tests and any repair work that may be required.
t  If the engine starts, runs for a short period and then stops, after fault finding, repairs or component tests, then the fault may lie with the immobiliser blocking the engine control unit. The event memory must then be interrogated and, if necessary, the control unit must be adapted.
