What is C0B97?
The diagnostic trouble code (DTC) C0B97 is a relatively uncommon error code that typically indicates an issue related to the vehicle's body control module (BCM) or an associated component. In simpler terms, it suggests that the car's electronic systems responsible for various body functions, such as lighting, door locks, and power windows, are not communicating correctly or have detected a fault. When this code appears, it can lead to a variety of symptoms, potentially affecting the vehicle's functionality and safety. For instance, drivers might experience problems with electronic accessories not working properly, which can be inconvenient and frustrating. It's also important to note that ignoring this code could lead to further complications, as the underlying issue may worsen over time. Thus, understanding the implications of code C0B97 is crucial for maintaining your vehicle's performance. This code is particularly prevalent in 2015 to 2018 Honda Accord models, though other manufacturers may encounter it as well. If you see this code, it's essential to take action promptly to avoid more extensive repairs down the line.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0B97 is present:
- Check engine light stays on constantly, indicating ongoing issues with the vehicle's electrical system.
- Power windows or locks may fail to operate, affecting driver convenience and safety.
- Dashboard lights behave erratically or fail to illuminate, which can hinder visibility of critical information.
- Vehicle may experience intermittent electrical failures, leading to further complications.
- In some cases, the vehicle may fail to start due to issues with the BCM.
Possible Causes
Most common causes of C0B97 (ordered by frequency):
- The most common cause of C0B97 is a faulty body control module, which has a likelihood of approximately 40%. This could be due to water intrusion, electrical shorts, or software glitches.
- Another frequent cause is damaged wiring or connectors, accounting for around 30% of cases. Corrosion or frayed wires can disrupt communication between the BCM and other components.
- Thirdly, a blown fuse in the BCM circuit can cause this error, which is relatively easy to fix and can be prevented by regular inspections.
- Less common but serious causes include short circuits or issues with the vehicle's main electrical harness, which can lead to extensive electrical problems.
- A rare cause might include software issues within the BCM, requiring an update or reprogramming to resolve.
