The automobile fault code P1BEF has an estimated repair time of 1.0 hour.

The cost of diagnosis and fixing is based on the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the cost of fixing the P1BEF fault code will likely fall within this range.

It is important to note that the cost may vary depending on the severity of the issue and the specific repair shop chosen.

The P1BEF code is related to the HybridElectric Vehicle battery pack. The battery pack contains 288 cells grouped in parallel and connected in-series.

The battery energy control module monitors the voltage of the 96 battery cell groups through the hybridEV battery interface control modules. The P1BEF code indicates a high voltage circuit issue with battery cell group 89.

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

The hybridEV powertrain control module 2 is responsible for diagnostic trouble code information.
