Code B1785 Pontiac Description

The seat adjuster motors are controlled by the Driver Seat Module (DSM) through the adjuster motor control circuits. In an inactive state both of the motor control circuits are grounded within the DSM. In an active state the DSM switches the appropriate motor control circuit to battery positive voltage. The direction of the adjuster motor rotation is determined by which of the motor control circuits is switched to battery positive voltage while the other remains grounded. During adjuster motor operation the DSM also monitors the current flow through the motor control circuits.
