C0545 CADILLAC Description

The power steering control module continuously monitors the digital torque sensor’s torque and index current signals. As the steering wheel is turned and torsional twist is applied to the steering shaft, the steering input and output shafts are monitored via the torque signal circuit and then processed by the power steering control module to calculate the steering torque.
