Circuit Description

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The memory seat module (MSM) receives voltage inputs from the tilt switch based on the position of the switch. The MSM then supplies battery voltage and a ground to the tilt motor control circuits depending on which direction of movement is requested.
