ABS Description and Operation: Magnasteer
WARNING: This page is about a different car, the 2006 Buick LaCrosse and 2006 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
The variable effort steering system, Magnasteer, incorporates a controller into the electronic brake control module (EBCM). The EBCM receives inputs from wheel speed sensors. The EBCM processes this information and controls the amount of current to the Magnasteer actuator to vary the rate of input torque required at the steering gear. A DTC is stored in the EBCM for a Magnasteer malfunction. A Magnasteer DTC C0450 will not cause the ABS or TRAC OFF indicators to go ON.
