The P1BB3 fault code indicates a high voltage issue in the HybridElectric Vehicle Battery 69 Circuit.

The battery pack contains 288 cells grouped in parallel and connected in-series. The battery energy control module monitors the voltage of the 96 battery cell groups through the hybridEV battery interface control modules. The battery energy control module communicates diagnostics and system status to the hybridEV powertrain control module 2.

The hybridEV powertrain control module 2 is responsible for diagnostic trouble code information.

What are the possible causes of the P1BB3 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1BB3 fault code.
