MSM Power and Grounds

WARNING: This page is about a different car, the 2011 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

Battery positive voltage is supplied at all times to the MSM through two different 25 A circuit breakers located in the rear fuse block. One circuit breaker is used by the MSM to apply power to the driver seat horizontal motor, front vertical motor, rear vertical motor, recline motor, and the lumbar horizontal motor. The second circuit breaker is used by the MSM to apply power to the driver seat lumbar vertical motor, the steering wheel and column motors, and the front passenger seat lumbar vertical motor. Battery positive voltage is also supplied at all times to the MSM through a 10 A fuse located in the rear fuse block. This voltage is used to power up the MSM. Ground is provided to the MSM through two separate ground circuits that are connected to a common ground.
