The automobile fault code P1BAC has an estimated repair time of 1.0 hour. The cost of fixing this fault code varies between $75 and $150 per hour, depending on the auto repair shop. The cost may also vary based on the severity of the issue and the type of vehicle.

Other factors that may influence the cost include the location of the repair shop, the experience of the mechanic, and the availability of replacement parts.

It is important to consider all of these factors when estimating the cost of fixing the P1BAC fault code.

The P1BAC code indicates a low voltage in the HybridElectric Vehicle Battery 67 Circuit.

The battery pack contains 288 cells grouped in parallel and connected in-series. There are three battery sections, each with its own hybridEV battery interface control module. The battery energy control module monitors the voltage of the 96 battery cell groups.

The hybridEV powertrain control module 2 receives diagnostic trouble code information from the battery energy control module.

The battery energy control module detects fault conditions and communicates system status to the hybridEV powertrain control module 2.
