Common Questions
What does C0955 mean and how does it affect my car?
The C0955 code indicates a fault in your vehicle's traction control system, often linked to communication issues with the ABS. This can lead to reduced vehicle stability, especially during slippery conditions. It's vital to address this issue promptly to ensure safe driving and maintain vehicle performance.
What are the most common causes of C0955 and how much does it cost to fix?
Common causes of C0955 include faulty wheel speed sensors, damaged wiring, and malfunctioning ABS control modules. Repair costs can range from $100 for wiring repairs to $800 for ABS control module replacement, depending on the issue.
Can I drive my car with C0955 or should I stop immediately?
While you might be able to drive your vehicle, it is not recommended to do so for long. Ignoring the C0955 code can lead to safety hazards, particularly on slippery roads. It's best to have the vehicle diagnosed and repaired as soon as possible.
How can I diagnose C0955 myself using GeekOBD APP?
To diagnose C0955 using the GeekOBD APP, connect the app to your vehicle's OBD2 port, perform a scan to retrieve codes, and review the freeze frame data for additional context. Look for any other related codes that may indicate underlying issues.
What vehicles are most commonly affected by C0955?
The C0955 code is frequently found in 2010-2018 Ford Fusion models, among others. It's important to check for any recalls or Technical Service Bulletins (TSBs) related to the traction control system for specific makes and models.
How can I prevent C0955 from happening again?
Regular maintenance, including inspecting and cleaning connectors and wiring associated with the ABS and traction control systems, can help prevent C0955. Additionally, ensuring that your vehicle's software is up to date can minimize the risk of software-related issues.
What is C0955?
The Diagnostic Trouble Code (DTC) C0955 indicates a problem with the traction control system, particularly in vehicles from manufacturers like Ford, including the 2010-2018 Ford Fusion. This code suggests that there is a fault in the communication between the traction control system and the anti-lock braking system (ABS). When the vehicle detects an issue, it may disable traction control to prevent further complications while driving. If this code appears, it can lead to several real-world implications: the traction control light may stay illuminated on the dashboard, and you may experience reduced vehicle stability, especially in slippery conditions. Additionally, you might notice that the vehicle does not respond well during acceleration, which can be particularly concerning in adverse weather. Ignoring this code could lead to further damage in the braking or traction control systems, resulting in more expensive repairs down the line. Regular diagnostic checks using tools like the GeekOBD APP can help identify the issue early and ensure your vehicle operates safely and efficiently.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0955 is present:
- The traction control warning light remains illuminated on the dashboard, indicating a persistent issue with the system.
- The vehicle experiences significant stability loss during acceleration, particularly on slippery surfaces, leading to a potential safety hazard.
- Drivers may notice that the engine hesitates or has reduced power, especially when cornering or during rapid acceleration.
- There may be a noticeable decrease in fuel efficiency, often by about 10-15%, as the vehicle struggles with traction control.
- Braking performance might be compromised, leading to longer stopping distances when the ABS system fails to engage properly.
Possible Causes
Most common causes of C0955 (ordered by frequency):
- {'cause': 'Faulty wheel speed sensors', 'likelihood': '40%', 'details': 'Wheel speed sensors are crucial for the traction control system; if they fail, it can lead to erroneous readings and trigger the C0955 code.'}
- {'cause': 'Damaged wiring or connectors', 'likelihood': '25%', 'details': 'Corroded or damaged wiring can interrupt signals between the ABS and traction control systems, causing failures.'}
- {'cause': 'Malfunctioning ABS control module', 'likelihood': '20%', 'details': 'The ABS control module is the brain of the system; if it malfunctions, the entire traction control system may be affected.', 'prevention': 'Regularly inspect wiring and connectors for wear and tear to prevent future issues.'}
- {'cause': "Software glitches in the vehicle's computer system", 'likelihood': '10%', 'details': "Sometimes the issue can stem from outdated software in the vehicle's control module, which can be resolved with a reflash or update."}
- {'cause': 'Less common mechanical issues with the traction control system', 'likelihood': '5%', 'details': 'Mechanical failures in parts like the brake calipers or hydraulic pump can also trigger this code, though they are rare.'}
