The P0BAD fault code refers to an issue with the Hybrid Battery Voltage Sense ‘W’ Circuit. This circuit is responsible for monitoring the voltage of the battery blocks in the HV (High Voltage) battery.

The HV battery is made up of 28 modules, each consisting of eight 1.2V cells in series. The battery smart unit, which monitors the voltage of the battery blocks, detects a malfunction if there is a voltage difference between the blocks that exceeds the standard. When this happens, the power management control ECU (HV CPU) will illuminate the Malfunction Indicator Lamp (MIL) and set the P0BAD Diagnostic Trouble Code (DTC). This fault code indicates an intermittent or erratic issue with the Hybrid Battery Voltage Sense ‘W’ Circuit.

It is important to address this problem promptly to ensure the proper functioning of the HV battery and the overall performance of the hybrid vehicle.
