Code C0176 Buick Description

The Power Steering Control Module (PSCM) monitors the temperature of the power steering system. The Power Steering Control Module monitors amperage output and input from an internal temperature sensor to calculate an estimated system temperature. If the Power Steering Control Module detects a high system temperature event is occurring, the amount of assistance is decreased to reduce system temperature, in an effort to prevent thermal damage to the power steering components. The Diagnostic Trouble Code (DTC) will be set when the maximum amperage output exceeds a calibrated value within the limited commanded output amperage range.
