Code B285A Buick Description
Two position sensors are hall effect sensors and are used by the steering column position control module. The steering column position control module provides a 12 V reference voltage and a ground to both the tilt and telescoping position sensors. The sensor feedback circuit voltage varies from 0-12 V. Each sensor is part of the motor assembly. The steering column position control module monitors the feedback voltage to determine the column position.
