The P0B32 fault code indicates that there is a high voltage in hybrid battery ‘D’. The HV battery in the vehicle is made up of nickel metal-hydride batteries and does not require external charging. The power management control ECU is responsible for maintaining a constant state of charge (SOC) in the HV battery while driving.

The HV battery consists of 28 modules, with each module containing eight 1.2 V cells in series.

The battery smart unit monitors the voltage of the battery blocks at 14 locations.

If there is a voltage difference between the battery blocks that exceeds the standard, the battery smart unit detects a malfunction.

When the malfunction is detected, the power management control ECU illuminates the Malfunction Indicator Lamp (MIL) and sets the P0B32 fault code.

What are the possible causes for the automobile fault code P0B32?

If you see the engine light or service engine soon warning light on, the fault code P0B32 could be the culprit. This code is often caused by a faulty battery smart unit or a faulty HV battery assembly. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. It’s important to address these possible causes to get your automobile back in top shape.

How can I visually inspect the wiring harness and connectors to fix the P0B32 fault code?
