The automobile fault code P1B84 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 of the P1B84 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time.

The P1B84 code refers to a performance issue in the HybridElectric Vehicle Battery 54 Circuit. The battery pack contains 288 cells grouped in parallel and series.

There are three battery sections, each made up of different numbers 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 diagnostic and system status to the hybridEV powertrain control module 2.

The P1B84 code indicates a fault condition in the battery circuit, which requires serviceable components to be checked and repaired.

What are the possible causes of the P1B84 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1B84 fault code.
