Circuit/System Description
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The power steering control module (PSCM) continuously monitors the thermal cycle counter of the steering gear. If the PSCM is replaced, the thermal cycle counter needs to be copied from the existing PSCM over to the new PSCM using the SPS EPS Setup Procedure. If there is no communication with the PSCM, replace the steering gear.
