13240 - Service Update. Reprogram the power steering control module. The power steering control module may disable the power steering assist feature. This is most likely to occur when the vehicle is first started and when the underhood temperature is extremely low, although in very rare instances, it may occur if the underhood temperature is extremely high. This could result in increased steering effort at low vehicle speeds, the display of a Service Power Steering DIC message, and the setting of DTC C056D. Power steering assist will return on subsequent ignition cycles if the underhood temperatures are no longer in these ranges.
