General notes on ignition system

Note:
^ The engine control module is equipped with self diagnosis.
^ 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 checked and if necessary erased.

^ Check fault memory and, if necessary, repair any faults and then erase fault memory.
