The factors that influence the cost of diagnosing and fixing the automobile fault code P1B51 are: – The estimated repair time is 1.0 hour.

– Auto repair shops typically charge between $75 and $150 per hour.

– The complexity of the issue and the required parts can also affect the cost. – The expertise and experience of the mechanic can also impact the cost. – The location of the repair shop can also affect the cost due to varying labor rates.

The P1B51 code indicates a low voltage in the HybridElectric Vehicle battery circuit. 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 communicates diagnostics and system status to the hybridEV powertrain control module 2.

All components related to the battery energy control module are serviceable.
