Circuit/System Description

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

The steering column has a tilt/telescoping control system that consists of an Steering Column Tilt Wheel and Telescope Control Module capable of serial data communication, a steering column power assembly with positioning motors and sensors, and a Steering Column Tilt Wheel and Telescope Switch. The Steering Column Tilt Wheel and Telescope Control Module will wake up either by the serial data or by the Steering Column Tilt Wheel and Telescope Switch.

Two position sensors are hall effect sensors and are used by the Steering Column Tilt Wheel and Telescope Control Module. The Steering Column Tilt Wheel and Telescope 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 Tilt Wheel and Telescope Control Module monitors the feedback voltage to determine the column position.

All DTCs and data from Steering Column Tilt Wheel and Telescope Control Module is communicated through the serial data and stored in the seat memory control module.
