General notes on injection
t  This section specifically addresses ignition system components. Other injection and ignition system components → Chapter.
t  For smooth operation of electrical components, voltage must be at least 11.5 V.
t  In some tests, the Engine control unit -J623- may recognise and memorise a fault. For this reason, once all tests and repairs are completed, the fault memory must be consulted and, if necessary, deleted → Chapter.
t  If, after troubleshooting and component repairs or tests, the engine should start only briefly, and then immediately stop running, it may be that the immobiliser is blocking the Engine control unit -J623-. In this case, if necessary, the Engine control unit -J623- must be adjusted → Chapter.
Safety measures → Chapter.
Data for checking, Spark plugs -Q- → Chapter
