Code B227B Description

The steering column is the mechanical linkage between the steering wheel and the steering gear. However, the steering column housing also contains the Power Steering Control Module (PSCM), motor and steering sensor, which are used to provide the power assist. The programmable module uses inputs from the sensor to determine when and how much assist is needed. The 12-volt brushless, reversible motor uses a worm gear and a reduction gear to apply the power assist to the steering column shaft. The steering column, module, motor and sensor are serviced as an assembly.
