Circuit Description

WARNING: This page is about a different car, the 2003 Pontiac Montana, 2003 Oldsmobile Silhouette, and 2003 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.

The rear side door actuator control module uses the power sliding door detent switch to determine when the door is latched, ajar, or open. The power sliding door detent switch is part of the sliding door rear latch assembly. The detent switch signal circuit is supplied 12 volts through a resistor within the module. When the power sliding door is open and the door switch plate plungers have made contact with the B-pillar switch plate pads, the detent switch signal circuit is pulled to ground. When the door latch makes contact with the striker and the latch moves to the ajar position, the detent switch signal circuit opens. As the door latch passes from the ajar position to the latched position the detent switch signal circuit is briefly pulled to ground.
