What is B0C97?
DTC B0C97 refers to a specific diagnostic trouble code that indicates a malfunction in the vehicle's body control module (BCM). This code is commonly seen in models like the 2016-2022 Ford Explorer and the 2017-2022 Hyundai Santa Fe. When the BCM detects an issue, it triggers the check engine light to alert the driver. The body control module is responsible for managing various electrical systems in the vehicle, including lighting, windows, and door locks. If B0C97 is present, you might experience issues with these systems. In practical terms, this may mean your power windows won't operate correctly, your interior lights won't turn on or off as expected, or your vehicle's security features might malfunction. Ignoring this code could lead to further complications, such as draining your car's battery or causing additional electrical failures. Therefore, it's crucial to address this issue promptly to maintain optimal performance and safety.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0C97 is present:
- The check engine light remains illuminated on the dashboard, indicating a persistent issue.
- Power windows may fail to operate, causing inconvenience for passengers who need to adjust their windows.
- Interior lights may flicker or remain on, which could drain the vehicle's battery over time.
- Door locks may not respond to commands from the key fob or internal switches, compromising security.
- The vehicle's alarm system may malfunction, leading to false alarms or failure to activate.
Possible Causes
Most common causes of B0C97 (ordered by frequency):
- The most common cause of B0C97 is a faulty body control module, which is responsible for managing various electrical systems. This issue occurs in approximately 60% of cases due to wear and tear.
- Another frequent cause is damaged wiring or connectors related to the BCM, which can lead to intermittent connectivity issues that trigger the code.
- Corrosion at the BCM connector is also a potential cause. Keeping the vehicle's electrical connections clean can prevent these issues.
- Less common but serious could be a battery failure, where a weak battery may not supply adequate power to the BCM, affecting its performance.
- A rare cause might involve software glitches within the BCM. Updating the vehicle's software can sometimes resolve these issues.
