Steering Wheel Rotation Sensor

The steering wheel rotation sensor measures the rate of rotation of the steering wheel by monitoring the steering wheel rotation ring as it passes through the sensor gap. The steering wheel rotation sensor uses the HS-CAN  bus to transmit information to the ABS module about whether the steering wheel is being turned left or right and how far it is being turned. The steering wheel rotation sensor is integrated into the Electronic Power Assist Steering (EPAS) column assembly and is not serviced separately. For information and diagnostics on the EPAS  system, refer to STEERING SYSTEM article.
