Circuit Description

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.
