Steering Column Position Sensor

The tilt position sensor is used by the MSM to store column positions in memory and to return the column to the stored memory positions. The MSM provides a 5-volt reference voltage and a ground to the tilt position sensor. The sensor feedback circuit voltage varies from 0.25-4.75 volts. Each sensor is mounted to its corresponding motor cable assembly. When the motor rotates its cable, the resistance of the sensor varies. The MSM monitors the feedback voltage to determine the column position via the tilt position sensor input circuits. When an entry or exit position is saved, the MSM stores the column positions by recording each position sensor's feedback voltage. When an entry or exit position is commanded, the module moves the motor until all the position sensor feedback voltages equal the feedback voltages stored in memory.
