The fault code is P1B7C. The estimated repair time is 1.0 hour.

The cost of fixing the fault code depends on the repair time.

Most auto repair shops charge between $75 and $150 per hour. These factors are influential in determining the cost of fixing the fault code.

The P1B7C code indicates a low voltage in the HybridElectric Vehicle Battery 51 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.

The P1B7C code is a fault condition that can be determined by the battery energy control module.

What are the possible causes of the P1B7C automobile fault code?
