Circuit/System Description

WARNING: This page is about a different car, the 2010 GMC Sierra and 2010 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The power steering control module (PSCM) monitors the 12V system voltage to make sure that the voltage stays within the proper range. Damage to components, and incorrect data input can occur when the voltage is out of range. The PSCM monitors the system voltage. If the PSCM detects a 12V system voltage outside an expected range, DTC C0800 will set.
