Power Supply

Power Supply





+30

Power (+30 circuit) is supplied via fuse 23 to control module pin 22.

The control module uses this current (+30 circuit) for its memory. The engine will not start without power supplied via the +30 circuit.

+15

Power (+15 circuit) is supplied via fuse 9 to control module pin 21.

Applying current (+15 circuit) to pin 21 activates the control module. The engine will not start without current from the +15 circuit.

Current from the main relay (M91-)

With the ignition switch in the ON position, the main relay is activated by the LH control module. The main relay supplies current to the DI/APC control module on pin 35.

This function makes spark plug burn-off possible in connection with switching off the ignition.
