OPERATION

General
Feed from the positive battery terminal (C0192) is supplied to fusible link 3 and fusible link 4 of the engine compartment fuse box (C0632) on an R wire. Fusible link 4 (C0574) provides a constant battery feed to the auxiliary relay (C0587) on an NW wire. The auxiliary relay is located in the passenger compartment fuse box.

NOTE: The auxiliary relay also controls operation of the heated seats.

Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the ignition switch is turned to the 'ignition' position, current flows across the switch (C0028) to fuse 8 of the passenger compartment fuse box (C0588) on an NW wire. Fuse 8 provides an ignition feed to the Central Control Unit (CCU) (C0593). The CCU is mounted directly onto the rear of the passenger compartment fuse box.

When the CCU receives an ignition feed from fuse 8, it energized the auxiliary relay by providing an earth path for the relay coil. The energized auxiliary relay provides a feed to fuse 12, which is also located in the passenger compartment fuse box. Fuse 12 (C0585) provides a feed to the sunroof switch (C0363) on an SR wire.

Open
When the bottom half of the sunroof switch is depressed (with the sunroof in the fully closed position), a feed is provided to the sunroof motor (C0614) from the switch (C0363) on a G wire. Current flows across the motor (C0614) and back to the switch (C0363) on an S wire. The switch (C0363) is earthed on a B wire. The motor will now power the sunroof back to the fully open position.

Close
When the top half of the sunroof switch is depressed (with the sunroof in the fully open position), a feed is provided to the sunroof motor (C0614) from the switch (C0363) on an S wire. Current flows across the motor (C0614) and back to the switch (C0363) on a G wire. The switch (C0363) is earthed on a B wire. The motor will now power the sunroof back to the fully closed position.

Tilt
When the top half of the sunroof switch is depressed (with the sunroof in the fully closed position), a feed is provided to the sunroof motor (C0614) from the switch (C0363) on an S wire. Current flows across the motor (C0614) and back to the switch (C0363) on a G wire. The switch (C0363) is earthed on a B wire. The motor will now power the sunroof to the tilt position.

When the bottom half of the switch is depressed (with the sunroof in the tilt position), a feed is provided to the sunroof motor (C0614) from the switch (C0363) on a G wire. Current flows across the motor (CO614) and back to the switch (C0363) on an S wire. The switch (C0363) is earthed on a B wire. The motor will now power the sunroof back to the fully closed position.
