Common causes of C0247 include a faulty ABS control module, damaged wiring, and malfunctioning wheel speed sensors. Repair costs can range from $100 for sensor replacements to $800 for module replacements, depending on the specific issue.
Can I drive my car with C0247 or should I stop immediately?
It's advisable to avoid driving your vehicle if C0247 is present, especially in conditions requiring reliable braking. The ABS system may not function correctly, increasing the risk of accidents.
How can I diagnose C0247 myself using GeekOBD APP?
To diagnose C0247 using GeekOBD APP, connect the app to your vehicle's OBD2 port, scan for trouble codes, and review freeze frame data. Look for any related codes and note the conditions under which the code was triggered.
What vehicles are most commonly affected by C0247?
DTC C0247 is frequently seen in popular vehicles like the 2015-2018 Honda Accord, Toyota Camry, and Ford Fusion. Regular maintenance checks can help prevent issues associated with the ABS system.
How can I prevent C0247 from happening again?
To prevent C0247 from recurring, ensure regular maintenance on your braking system, inspect ABS components periodically, and promptly address any warning lights or unusual brake behavior.
What is C0247?
DTC C0247 indicates a malfunction within the Anti-lock Brake System (ABS) control module, which is crucial for vehicle safety. When this code appears, it typically signifies that the ABS system has detected an issue that may compromise braking performance. This can stem from various factors, including electrical faults, sensor failures, or internal module faults. The ABS system is designed to prevent wheel lockup during hard braking, allowing the driver to maintain steering control. If the C0247 code is triggered, the ABS warning light on the dashboard may illuminate, and in some cases, the traction control system may also be disabled. Ignoring this code can lead to decreased braking efficiency, particularly in slippery conditions, increasing the risk of accidents. Vehicle owners, especially those driving models like the Honda Accord, Toyota Camry, or Ford Fusion from specific years, should address this issue promptly. A malfunctioning ABS system not only affects safety but can also lead to costly repairs if left unchecked. Understanding the implications of DTC C0247 is vital for any vehicle owner to ensure their safety and the reliability of their vehicle.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0247 is present:
- The ABS warning light is illuminated on the dashboard, indicating a fault in the anti-lock braking system.
- Unusual braking behavior, such as the brakes feeling spongy or the pedal pulsating unexpectedly during braking.
- Loss of traction control functionality, which may be noticeable during slippery conditions or sharp turns.
- Increased stopping distance, which may be evident to the driver, particularly in emergency braking situations.
- Potential noise from the ABS system, such as clicking or grinding, when brakes are applied.
Possible Causes
Most common causes of C0247 (ordered by frequency):
- The most common cause of DTC C0247 is a faulty ABS control module, accounting for approximately 40% of cases. This module can fail due to wear and tear or electrical issues.
- Another common cause is damaged wiring or connectors within the ABS system, which can lead to intermittent signals and system malfunctions.
- A malfunctioning wheel speed sensor can also trigger this code. Regular checks can help prevent this issue by ensuring sensors are clean and connections are secure.
- Less commonly, software issues within the ABS module can cause the C0247 code. Updating the vehicle's software may resolve these glitches.
- In rare cases, hydraulic pump failures in the ABS system can lead to DTC C0247, requiring more extensive repairs or replacement.
