The P1E81 fault code is related to the HybridElectric Vehicle battery pack.

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 will determine when a fault condition is present and communicate it to the hybridEV powertrain control module 2. The P1E81 code specifically refers to a fault in Battery 86 Circuit.
