What is C08F7?
The diagnostic trouble code (DTC) C08F7 typically indicates a problem with the vehicle's active suspension system, particularly in vehicles like the 2015-2020 Ford Explorer and 2016-2022 Chevrolet Malibu. This code is triggered when the vehicle's onboard diagnostic system detects a failure in the communication or performance of the suspension control module. The active suspension system is designed to adjust the vehicle's ride height and comfort level based on driving conditions and load, which improves handling and safety. When C08F7 is present, drivers may experience a rough ride, unusual handling characteristics, or warning lights on the dashboard. Ignoring this code can lead to further suspension damage and increased repair costs. In the worst-case scenario, it may affect the vehicle's stability while driving, particularly during cornering or sudden stops. Regular diagnostics and maintenance checks are crucial to catch these issues early and ensure safe driving conditions.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C08F7 is present:
- The check engine light illuminates, often remaining on until the issue is resolved.
- There are noticeable changes in ride quality, such as excessive bouncing or stiffness during driving.
- The vehicle may exhibit erratic handling characteristics, especially during turns or when loaded.
- You may hear unusual noises from the suspension components, indicating possible wear or failure.
- Fuel efficiency could decline due to the active suspension system working harder to compensate for malfunctions.
Possible Causes
Most common causes of C08F7 (ordered by frequency):
- The most common cause of C08F7 is a malfunctioning suspension control module, which accounts for approximately 40% of cases. This module can fail due to electrical issues, water intrusion, or software glitches.
- Another potential cause is damaged wiring or connectors in the suspension system. Corrosion or wear can lead to poor connections, which affects communication within the system.
- Faulty suspension components, such as struts or shocks, can also trigger C08F7. Regular inspections can help prevent these issues by identifying wear early.
- Less commonly, the issue may arise from issues with the vehicle's onboard computer or software, which may require a reprogramming or update from a dealership.
- In rare cases, a complete failure of the active suspension system may occur due to severe damage or wear, necessitating a full system replacement.
