1.1 General notes on ignition system
♦ For trouble-free operation of electrical components, a voltage
of at least 11.5 V is necessary.
♦ Certain tests may lead to an event being detected by the con‐
trol unit and stored. Then after completing all checks and
repairs, read event memory and erase if necessary ⇒ vehicle
diagnostic tester “Guided functions”.
♦ If, after fault finding, repairs or component tests, the engine
starts, runs for a short period and then stops, then the fault
may be that the immobilizer is blocking the engine control unit.
In this case, the control unit must be adapted using ⇒ vehicle
diagnostic tester under “Guided functions”.
