Steering Wheel Rotation Sensor: Notes

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 rotation sensor uses 2 signal lines 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 rotation sensor does not indicate the position of the steering wheel relative to straight-ahead. The AdvanceTrac® system learns this position by comparing the steering wheel position with other signals and storing the position it has learned. The AdvanceTrac® system confirms this position and modifies it as necessary during every new driving cycle.
