What is B0F6A?
The DTC code B0F6A indicates a fault in the high voltage battery pack of hybrid and electric vehicles. This code is particularly common in models such as the 2017-2022 Toyota Prius and the 2018-2021 Honda Insight, both of which rely heavily on their hybrid battery systems for optimal performance. When a vehicle's onboard diagnostics detect an issue with the high voltage battery pack, it triggers the B0F6A code to alert the driver of potential problems. This fault can manifest as a decrease in engine performance, irregular battery charging, or even the activation of the vehicle's warning lights. If not addressed promptly, this issue can lead to reduced fuel efficiency and ultimately affect the vehicle's drivability. Drivers may notice symptoms such as the check engine light illuminating or the hybrid system warning light appearing on the dashboard. Ignoring this code can lead to increased repair costs over time, as further damage to the battery pack or associated systems may occur if the issue is not resolved. Therefore, it's essential to have the vehicle diagnosed and repaired by a professional technician who understands the intricacies of hybrid systems.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0F6A is present:
- Check engine light stays on constantly, indicating a fault in the hybrid system.
- Engine hesitates during acceleration, leading to a noticeable drop in performance.
- Fuel economy decreased by 10-20%, affecting overall efficiency and operating costs.
- Battery charging indicator fluctuates unexpectedly, suggesting issues with the battery management system.

Possible Causes
Most common causes of B0F6A (ordered by frequency):
- The most common cause of B0F6A is a worn-out or failing high voltage battery pack, which has a likelihood of around 70%. As batteries age, their capacity diminishes, leading to performance issues.
- Another cause could be a fault in the battery management system (BMS), which is responsible for monitoring the battery's health. This typically involves software issues or wiring faults.
- Poor connections or corrosion on battery terminals can also trigger B0F6A, emphasizing the importance of regular maintenance checks.
- Less common but serious causes include physical damage to the battery pack due to accidents or improper handling during repairs.
- A rare cause could be manufacturing defects in the battery cells, which may be covered under warranty depending on the vehicle's age and mileage.
