ABS Description and Operation: MAGNASTEER
WARNING: This page is about a different car, the 2003 Pontiac Grand Prix. 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 EBTCM. The EBTCM receives inputs from wheel speed sensors. The EBTCM 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 EBTCM for a MAGNASTEER malfunction. A MAGNASTEER DTC C0450 will not cause the ABS or TRAC OFF indicators to go on. Refer to VARIABLE STEERING EFFORT for more information.
