What is B0F96?

The diagnostic trouble code (DTC) B0F96 is a manufacturer-specific code that typically indicates a problem related to the vehicle's hybrid system or battery management system, particularly in many Toyota models such as the 2016-2020 Toyota Camry and RAV4. This code signifies that there is a malfunction detected within the hybrid control module, which is responsible for managing the electric and combustion engines' integration. When the B0F96 code is triggered, it often leads to the vehicle entering a ‘limp’ mode to prevent further damage to the hybrid system. Real-world implications include reduced fuel efficiency, diminished vehicle performance, and the illuminated warning lights on the dashboard, signaling the driver to have the vehicle checked. Ignoring this code can lead to more serious issues, including complete failure of the hybrid system, which could result in costly repairs. It is essential for owners to understand that timely diagnostics and repairs can prevent these complications and ensure the longevity of their hybrid vehicle.

Symptoms

Common symptoms when B0F96 is present:

  • The check engine light remains illuminated, indicating an ongoing issue with the hybrid system.
  • The vehicle may exhibit sluggish acceleration or reduced power during driving, causing concerns about performance.
  • Drivers might notice a significant drop in fuel economy, with reports of decreases ranging from 10-20%.
  • The hybrid system may occasionally fail to engage, leading to a reliance solely on the gasoline engine.
  • The vehicle may enter a 'limp mode,' limiting speed and power to protect the hybrid system.

Possible Causes

Most common causes of B0F96 (ordered by frequency):

  1. The most common cause of the B0F96 code is a faulty hybrid control module, with a likelihood of about 60%. This can result from software issues or electrical malfunctions.
  2. Another potential cause is a malfunctioning battery management system (BMS), which can lead to improper charging or discharging of the hybrid battery.
  3. Loose or corroded wiring connections within the hybrid system can also trigger this code, highlighting the importance of regular inspections.
  4. Less common but serious causes include a failing hybrid battery, which may require expensive replacement if not addressed promptly.
  5. Rarely, issues with the vehicle's main engine control unit (ECU) can cause false readings that trigger the B0F96 code.
