Gm Electric Power Steering system delivers steering assist

On a GM electric power steering system, if the steering wheel is turned to its maximum rotation(against the steering stop) and held there, the power steering control module (PSCM) will respond by commanding the maximum amount of currnet to the EPS motor. Jus tlike the old hydraulic systems, the electric system tries to provide assist to overcome the resistance of the steering stop. But if the steering wheel is held in this position for an extended period of time, the PSCM will go into overload protection mode to avoid system thermal damage. In this mode, the PSCM will limit the amount of current commanded to the EPS motor, which has the effect of reducing the power steering assist level.
