The P0A84 fault code refers to the Hybrid Battery Pack Cooling Fan 1 Control Circuit being low.

This code indicates a problem with the cooling fan that is responsible for regulating the temperature of the hybrid battery pack.

The cooling air flows into the rear seat inlet and travels through an intake duct to the battery blower assembly in the luggage compartment.

It then flows through another intake duct to the HV battery assembly, cooling the battery modules from top to bottom. The exhaust air is discharged into the cabin and outside of the vehicle through an exhaust duct. The battery ECU uses temperature sensors to detect the HV battery assembly’s temperature and controls the battery blower assembly accordingly.

The power management control ECU controls the speed of the cooling fan by supplying power to the battery blower relay.

The fan speed is adjusted based on the HV battery temperature. If you encounter the P0A84 fault code, it means that there is an issue with the control circuit of the Hybrid Battery Pack Cooling Fan 1. This can lead to inadequate cooling of the battery pack, potentially causing overheating and other related problems.

It is important to have this issue diagnosed and repaired by a qualified technician to ensure the proper functioning of your hybrid vehicle.

What are the possible causes of the automobile fault code p0a84?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P0A84 could be the culprit. This code is often caused by a faulty battery cooling blower assembly, an open or shorted harness, poor electrical connections in the blower assembly circuit, a faulty integration relay, a faulty battery smart unit, or a faulty power management control ECU.
