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 P0B3D, P0B42, P0B47, P0B4C, P0B51, P0B56, P0B5B, P0B60, P0B65, P0B6A, P0B6F, P0B74, P0B79, P0B7E, P0B83, P0B88, P0B8D, P0B92, P0B97, and P0B9C are type B DTCs.
The drive motor generator battery control module commands the battery vent fan to high speed.
If more than 4 of these DTCs are set, the drive motor generator battery sends a message to the hybrid powertrain control module to reduce the power use limit to 50 percent.
