B285A CADILLAC Description
The steering column has a tilt/telescoping control system that consists of an Steering Column Position Control Module capable of serial data communication, a steering column power assembly with positioning motors and sensors, and a steering column tilt and telescope switch. The steering column position control module will wake up either by the serial data or by the steering column tilt and telescope switch.
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.
