Circuit/System Description
WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
Voltage is supplied to the power steering control module (PSCM) by the battery positive (B+) voltage circuit. The PSCM monitors the supplied voltage to determine if it is within a valid operating range. Damage to components, and incorrect data may occur if the voltage is out of range. The PSCM disables all outputs, and sets DTC C0895 if high or low battery voltage is detected.
