Power Seat System Operation
There are 2 options of power seats available with this system. One option
is the base power seat and it is limited to positioning the seat vertically
and horizontal only. The other option is a full feature seat that can position
the seat vertically, horizontally and reclining the back cushion. Battery
voltage is supplied to the power seat switch from the SEAT 25A circuit breaker.
While the seat adjuster switches are in an inactive state the switch contacts
are closed to the adjuster switch ground circuit. When a seat adjuster switch
is pressed to an active state the switch contact is closed to the battery
voltage supply circuit. Each seat adjuster motor is controlled by the seat
adjuster switch through 2 motor control circuits. The seat adjuster motors
are bidirectional and the direction of adjuster motor rotation is determined
by which of the adjuster motor control circuits is switched to battery voltage
while the other remains grounded.
