The fault code P1BAA is related to the hybrid battery pack. The code indicates that the battery pack is not able to maintain the required voltage level.

The possible causes of this fault code include a faulty battery pack, a damaged battery cell, or a malfunctioning battery management system. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this issue can range from $75 to $150 per hour, depending on the auto repair shop.

The P1BAA 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 four hybridEV battery interface control modules. The P1BAA code indicates a fault condition in the HybridElectric Vehicle Battery 66 Circuit High Voltage.

The battery energy control module communicates diagnostics and system status to the hybridEV powertrain control module 2 through serial data.
