Circuit Description

WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The rear steering gear motor is a 3 phase DC motor. It has 3 hall effect switches inside the motor assembly. The rear wheel steering control module monitors the hall switches for proper switch position, and will shut down the system if a invalid switch combination is detected. A DTC C0527 will set at that time.
