Common Questions
What does C0248 mean and how does it affect my car?
DTC C0248 indicates an issue with the ABS pump relay circuit. This can affect your vehicle's ability to stop safely, especially in adverse conditions. If this code is triggered, it’s crucial to have your vehicle checked to prevent potential accidents.
What are the most common causes of C0248 and how much does it cost to fix?
The primary cause of C0248 is usually a faulty ABS pump relay, followed by damaged wiring. Repair costs can range from $50 for a simple relay replacement to $1000 for a complete module replacement, depending on the issue's severity.
Can I drive my car with C0248 or should I stop immediately?
While you may still be able to drive your vehicle, it is unsafe to do so if the ABS system is compromised. Stopping distances may increase, and traction control features may not function correctly, so it’s advisable to get it inspected promptly.
How can I diagnose C0248 myself using GeekOBD APP?
To diagnose C0248, connect the GeekOBD APP to your vehicle's OBD2 port, retrieve the trouble codes, and check freeze frame data. This will give you an overview of the conditions when the fault occurred, guiding you in your troubleshooting efforts.
What vehicles are most commonly affected by C0248?
DTC C0248 is commonly found in 2010-2020 Ford and Chrysler models, including the Ford Explorer and Chrysler 300. If you own one of these vehicles, be vigilant for ABS warning lights.
How can I prevent C0248 from happening again?
Regular maintenance of your vehicle's electrical system, including cleaning connections and replacing worn components, can help prevent C0248. Additionally, routine inspections of the ABS system can catch issues before they develop.
What is C0248?
The diagnostic trouble code (DTC) C0248 indicates a problem with the ABS (Anti-lock Braking System) pump relay circuit. Specifically, this code suggests that the ABS control module has detected a fault in the electrical circuit that powers the ABS pump. In simpler terms, the ABS system is not functioning as intended, which could lead to compromised braking performance. This issue is significant because the ABS helps prevent wheel lock-up during hard braking, enhancing vehicle safety. If the ABS is not operational, you may experience longer stopping distances, especially on slippery or wet roads. Commonly reported in vehicles such as the Ford Explorer, Chrysler 300, and Dodge Charger from the years 2010 to 2020, this code usually appears alongside the illumination of the ABS warning light on your dashboard. Ignoring this issue can lead to more severe braking problems, making it crucial to address it promptly. In practical terms, if you encounter this code, it’s advisable to have your vehicle inspected as soon as possible, as it may affect your car's handling and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0248 is present:
- ABS warning light illuminates on the dashboard, indicating a malfunction in the ABS system.
- Increased stopping distances observed during braking, especially in wet or slippery conditions.
- Braking system feels different or inconsistent, with possible pulsation felt in the brake pedal.
- Unusual noises coming from the ABS module during braking, which might include grinding or clicking sounds.
- Potential loss of traction control features, leading to decreased vehicle stability during cornering.
Possible Causes
Most common causes of C0248 (ordered by frequency):
- The most common cause of DTC C0248 is a faulty ABS pump relay, accounting for about 60% of cases. This relay controls the power supply to the ABS pump, and if it fails, the pump won't operate.
- A second likely cause is damaged wiring or loose connections in the ABS circuit. Over time, wires may corrode or become frayed, leading to intermittent or complete loss of power to the ABS system.
- The third possibility is a malfunctioning ABS control module, which can fail due to electrical issues or internal component failures. Preventative maintenance, such as regularly checking and cleaning connections, can help mitigate this risk.
- A less common but serious cause could be a failed ABS pump itself, which may require replacement if found defective.
- Finally, a rare cause could include software issues within the ABS control module, which might necessitate a software update or reprogramming.
