Description
If individual components of the engine management system are faulty, the "Check Engine" indicator lights up on the instrument panel (north American version only).
The ignition system uses four dual ignition coils. A spark discharge occurs at every engine revolution (i.e. twice per working cycle). Coil #1 supplies discharge voltage to cylinders 1 and 6, coil #2 to cylinders 5 and 8, coil #3 to cylinders 4 and 7, coil #4 to cylinders 2 and 3.
