Circuit Description

WARNING: This page is about a different car, the 2002 Pontiac Montana, 2002 Oldsmobile Silhouette, and 2002 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.

The seat adjuster motors are controlled by the memory seat module through the adjuster motor supply circuits. The memory seat module also monitors current flow through the adjuster motor supply circuits. In an active state the adjuster motor supply circuits are switched to power and ground within the memory seat module. The direction of the adjuster motor rotation is determined by which of the supply circuits is switched to battery positive voltage and which is grounded.
