Circuit Description

Battery positive voltage is supplied to the memory seat module (MSM) from the PWR SEAT Circuit Breaker located in the rear fuse block. When commanded, this voltage is used by the MSM to power the seat motors through the motor control circuits. During memory recall functions and manual seat functions, the driven motor current is monitored through the motor control circuits by the MSM. When an overcurrent condition is detected, the MSM disables the seat motors in order to protect the internal MSM circuitry.
