Action Taken When the DTC Sets

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.

DTCs P0A9C, P0A9D, P0A9E, P0AC6, P0AC7, P0AC8, P0ACB, P0ACC, P0ACD, P0AE9, P0AEB, and P0AEA are Type B DTCs.
When two or more sensors fail, the drive motor generator battery control module sends a serial data message to the drive motor generator control module to reduce the power use limit to 50 percent and the drive motor battery cooling fan will default to run.
If all four sensors fail, the state of charge (SOC) will be considered invalid.
