Action Taken When the DTC Sets
WARNING: This page is about a different car, the 2012 GMC Yukon, 2012 Chevrolet Tahoe, and 2012 Cadillac Escalade. 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.
- If two sensors fail, the drive motor generator battery sends a message to the hybrid powertrain control module to reduce the power use limit to 50 percent and the battery vent fan will default to run.
- If all four sensors fail, the state of charge (SOC) will be considered invalid.
