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 P0B3E, P0B43, P0B48, P0B4D, P0B52, P0B57, P0B5C, P0B61, P0B66, P0B6B, P0B70, P0B75, P0B7A, P0B7F, P0B84, P0B89, P0B8E, P0B93, P0B98, P0B9D, P0BA2 and P0BA7 are type B DTCs.
The drive motor generator battery control module commands the drive motor generator battery coolant fan to high speed.
If more than 4 of these DTCs are set 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.
