The P0A85 fault code refers to the Hybrid Battery Pack Cooling Fan 1 Control Circuit being too high. 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 battery blower assembly located on the right side of the luggage compartment.

It then travels through an 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 temperature of the HV battery assembly. When the temperature rises to a certain level, the battery blower assembly is activated to cool the battery pack.

The speed of the cooling fan is controlled by the power management control ECU, which sends command signals to adjust the fan speed based on the battery temperature.

If the P0A85 fault code is triggered, it means that there is an issue with the control circuit of the cooling fan. This could be due to a faulty relay or a problem with the power management control ECU. It is important to address this issue promptly to prevent overheating of the hybrid battery pack, which can lead to further damage and potential safety hazards.

What are the possible causes of the automobile fault code p0a85?

If you see the engine light on or the service engine soon warning light, the fault code P0A85 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. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look out for broken, bent, pushed out, or corroded pins in the connectors.
