Circuit Description
WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
The power sliding door (PSD) latch/unlatch motor/actuator is responsible for latching and unlatching the PSD when the power sliding door control module (PSDM) has received a request to open or close the door. The latch/unlatch motor/actuator receives battery positive voltage from the PSDM via the PSD latch/unlatch motor/actuator control circuit. Ground is supplied to the motor/actuator via G301 for the left side sliding door and G302 for the right side sliding door. The PSDM monitors the voltage on the latch/unlatch motor/actuator control circuit during latching and unlatching operations in order to determine when a failure has occurred.
