The P1B27 code is related to the HybridElectric Vehicle battery pack.

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 will determine when a fault condition is present and communicate it to the hybridEV powertrain control module 2 through serial data.

The P1B27 code indicates a high voltage in the HybridElectric Vehicle Battery 32 Circuit. The hybridEV powertrain control module 2 is the host controller for diagnostic trouble code information.

What are the possible causes of the P1B27 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1B27 fault code. This code is usually 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.

How can one visually inspect the related wiring harness and connectors to fix the P1B27 fault code?

If you’re experiencing the P1B27 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have 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.
