The automobile fault code P1B79 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of diagnosis and fixing the P1B79 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time.

The P1B79 code refers to a low voltage issue in the HybridElectric Vehicle battery pack. The battery pack contains 288 cells grouped in parallel and in-series. There are three battery sections, each made up of 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 P1B79 code is a fault condition that can be determined by the battery energy control module.

What are the possible causes of the P1B79 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1B79 fault code. This code is caused by a faulty hybrid/electric vehicle battery pack or a faulty hybrid/electric vehicle battery interface control module. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
