Power Steering Control Module

The Power Steering Control Module, mounted behind the right side of the steering column to the I/P carrier, uses the Vehicle Speed Sensor and Steering Wheel Speed Sensor input to regulate electrical current to the Fluid Flow Actuator.

The Power Steering Control Module also detects faults with the Steering Wheel Speed Sensor, the Fluid Flow Actuator, and associated circuits. Upon detecting a fault, the Power Steering Control Module disables the EVO system and the vehicle operates with maximum power assist until the driver turns the ignition to the "OFF" position. When the vehicle is restarted, the Power Steering Control Module resets and enables EVO operation until it detects another fault. The Power Steering Control Module has fault code memory and can pinpoint specific faults.
