What is B0D97?
The B0D97 diagnostic trouble code (DTC) primarily relates to the vehicle's body control module (BCM) and indicates that there’s an issue with the power liftgate control system. This code is often seen in popular models like the 2016-2020 Toyota RAV4, where the BCM monitors various systems including the power liftgate, door locks, and interior lighting. When the BCM detects a malfunction in the liftgate system, it triggers the B0D97 code. A liftgate that doesn’t open or close properly can be a nuisance, affecting cargo access and overall vehicle utility. Ignoring this code may lead to further electrical issues and increased repair costs. Drivers may notice that the liftgate fails to respond to commands or that it operates erratically. It’s crucial to address this code promptly, as it can also affect other electronic systems in the vehicle. Diagnostics typically involve inspecting the liftgate motor, wiring, and the BCM itself to pinpoint the exact cause of the issue. This code can be particularly frustrating because it may not always manifest through obvious symptoms, making it essential to utilize diagnostic tools like the GeekOBD APP to retrieve and analyze data effectively.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0D97 is present:
- The power liftgate does not open or close when activated by the key fob or interior switch, indicating a potential electrical failure.
- Drivers may experience intermittent operation of the liftgate, where it functions sporadically, causing frustration and inconvenience.
- Fuel economy may decrease if the BCM is drawing excess power due to a malfunctioning component, potentially impacting overall vehicle performance.
- In some cases, the dashboard warning lights may illuminate, particularly the check engine light, signaling that the vehicle's systems are not operating correctly.
- Additional symptoms may include unusual sounds from the liftgate area, such as grinding or clicking noises, indicating mechanical failure.
Possible Causes
Most common causes of B0D97 (ordered by frequency):
- The most common cause of B0D97 is a faulty liftgate motor, which is responsible for the opening and closing operation. This has a likelihood of around 60%.
- Another possibility is damaged or corroded wiring in the liftgate control circuit, which can lead to intermittent or complete failure of the liftgate function.
- A malfunctioning body control module (BCM) itself can also trigger this code. Prevention tips include regular inspections and avoiding water exposure in the BCM area.
- Less common but serious causes include a blown fuse in the liftgate circuit, which could lead to a complete loss of power to the liftgate system.
- A rare cause may involve software glitches within the BCM that require a reprogramming or update to rectify.
