The fault code P1BA9 indicates a problem with the hybrid battery pack coolant pump.

The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. Other factors that may influence the cost include the location of the repair shop, the severity of the issue, and the type of vehicle.

It is important to address this issue promptly to avoid further damage to the hybrid battery pack.

The P1BA9 code indicates a low voltage in the HybridElectric Vehicle Battery 66 Circuit. The battery pack contains 288 cells grouped in parallel and series. The battery energy control module monitors the voltage of the 96 battery cell groups through the four hybridEV battery interface control modules.

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

The hybridEV powertrain control module 2 is the host controller for diagnostic trouble code information.

What are the possible causes of the P1BA9 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1BA9 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.
