The fault code P1A1F is related to the hybrid battery pack in a vehicle.

The code indicates a malfunction in the battery pack’s cooling system. The diagnosis process involves checking the battery pack’s temperature sensors and the cooling fan’s operation. The estimated repair time for this fault code is 1.0 hour.

The fixing cost will depend on the auto repair shop’s hourly rate, which typically ranges between $75 and $150 per hour. Other factors that may influence the cost include the severity of the problem and the need for replacement parts.

The P1A1F code refers to a fault in the Battery Energy Control Module (BECM) of the hybrid vehicle.

The BECM monitors the battery voltage and terminal voltage of the hybrid battery system. If the BECM detects that the hybrid battery system voltage is low, it will trigger the P1A1F fault code. This fault code is communicated to the Hybrid Powertrain Control Module (HPCM) for diagnosis and repair.

It is important to address this fault code promptly to ensure the proper functioning of the hybrid battery system.

What are the possible causes of the P1A1F fault code that triggers the engine light or service engine soon warning light?

If you see the engine light or service engine soon warning light on, it could be due to the P1A1F fault code. This code is triggered by a faulty Drive Motor Generator Battery Control Module, an open or shorted harness, or poor electrical connection in the module circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
