The automobile fault code P1BB4 is a diagnostic trouble code related to the hybrid battery pack. The code indicates a malfunction in the battery pack’s cooling system. The estimated repair time for this issue is 1.0 hour.

The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour. Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P1BB4 code refers to a fault in the HybridElectric Vehicle battery pack.

The battery pack contains 288 cells grouped in parallel and connected in-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.
