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.
Circuit Description
The rear wheel steering module monitors the input signal of the rear wheel position sensor and the hall sensor circuits. The rear wheel steering module tracks the signals sent by the rear wheel position sensor and the hall sensor circuits, phase A, phase B, and phase C. If any one of the hall sensor circuits are open, shorted to voltage or shorted to ground while the rear steering motor is tracking the rear wheel position sensor, an invalid motor position will occur, thus setting the DTC.
If the rear wheel position sensor signals have invalid values the rear wheel steering control module will not be able to track the position of the rear wheel position sensor, causing an invalid motor position, thus setting the DTC.
