General notes on ignition system
^ Only the components which specifically relate to the ignition system are covered here. For the other components of the injection and ignition system.
^ For trouble-free operation of the electrical components, a voltage of at least 11.5 V is necessary.
^ Disconnecting and connecting the battery must only be done with the ignition switched off, otherwise the engine control module could be damaged.
^ During some checks it is possible that the control module will detect and store a fault. Therefore, after completing all checks and repairs the fault memory must be interrogated and, if necessary, erased.
^ 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 immobilizer which is blocking the engine control unit. In such cases the control unit must be adapted; Refer to Adapting components and functions.
