Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Power Steering System Description and Operation
The Magnasteer® system is a speed-dependent power steering system. The Magnasteer® system provides power assist at varying levels depending on need.
A bi-directional magnetic rotary actuator in the steering gear adjusts the amount of torque (driver effort) necessary to turn the steering wheel.
The Magnasteer® is controlled through the ABS module and varies the torque by adjusting the current flow through the actuator.
The amount of adjustment will be directly related to the vehicle speed. The controller receives speed-related input signals from the vehicle speed sensor.
Refer to Variable Effort Steering (Magnasteer®) for more information on Magnasteer®.
