The P1B89 code refers to a high voltage issue in the HybridElectric Vehicle battery circuit. The battery pack contains 288 cells grouped in parallel and series.

There are three battery sections, each with a different number of cells and cell groups. 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.

All components related to the battery energy control module are serviceable.

What are the possible causes of the P1B89 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1B89 fault code.
