The P0AFF fault code is related to the Hybrid Battery System Voltage in your vehicle. The Engine Control Module (ECM) constantly monitors this voltage to ensure it is within the factory specifications. If the voltage signal is found to be lower than what is expected, the ECM will set the P0AFF code.

This code specifically indicates that the system voltage is too low for the voltage step-down converter to function properly.

When this fault code is triggered, it is important to address it promptly. A low system voltage can lead to various issues in your vehicle’s electrical system.

It can affect the performance of the voltage step-down converter, which is responsible for regulating the voltage supplied to different components. Ignoring this code can result in further damage to the electrical system and potentially lead to more expensive repairs. Therefore, it is recommended to have a qualified technician diagnose and fix the underlying cause of the P0AFF fault code to ensure the proper functioning of your vehicle.
