ABS Description And Operation: MAGNASTEER
WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue. 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 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. Refer to VARIABLE EFFORT STEERING SYSTEM DESCRIPTION AND OPERATION in Variable Effort Steering for more information.
