What is B0F88?

The DTC B0F88 is a diagnostic trouble code that indicates a malfunction within the vehicle's body control module (BCM) related to the tire pressure monitoring system (TPMS). This code is particularly prevalent in 2016-2020 Toyota RAV4 models, where it signifies that the system has detected an issue with the tire pressure sensor or the communication between the BCM and the tire pressure sensors. When the B0F88 code triggers, the TPMS warning light will typically illuminate on the dashboard, indicating that the system is not functioning properly. In practical terms, this means that the driver may not receive accurate tire pressure readings, which is crucial for safe driving. Ignoring this issue can lead to under-inflated tires, resulting in poor fuel economy, increased tire wear, and potentially dangerous driving conditions. Furthermore, the B0F88 code can also be associated with issues like faulty wiring, a defective BCM, or sensor malfunctions. Addressing this code promptly is vital for ensuring the safety and performance of your vehicle.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B0F88 is present:

  • The TPMS warning light illuminates on the dashboard, indicating a potential tire pressure issue.
  • Inconsistent tire pressure readings, which may fluctuate or show erroneous values.
  • Increased tire wear due to improper inflation, possibly leading to reduced handling and safety.
  • Unusual warning messages may appear in the vehicle’s display, often related to tire performance.
  • Decreased fuel efficiency, as under-inflated tires can lead to greater rolling resistance.

Possible Causes

Most common causes of B0F88 (ordered by frequency):

  1. Faulty tire pressure sensors are the most common cause, accounting for approximately 60% of cases. These sensors can fail due to age or damage.
  2. Electrical issues, such as corroded wiring or loose connections, are the second most common cause. These can disrupt communication between the BCM and sensors.
  3. A malfunctioning body control module (BCM) can also cause the B0F88 code, though this is less frequent. Regular maintenance can help prevent such failures.
  4. Less common causes include software glitches or updates needed for the BCM, which may require a dealership visit for resolution.
  5. Rarely, issues with the vehicle's battery or electrical system can impact the BCM's performance, leading to the B0F88 code.
