Common causes include faulty wheel speed sensors, issues with the ABS module, and damaged wiring. Repair costs can range from $150 for sensor replacement to over $1,200 for module replacement, depending on the severity of the issue.

Can I drive my car with C049C or should I stop immediately?

While you might be able to drive short distances, it is not safe to do so long-term. The traction control system is essential for maintaining vehicle stability, especially in adverse weather, so addressing this issue immediately is recommended.

How can I diagnose C049C myself using GeekOBD APP?

Using the GeekOBD APP, you can perform a scan to retrieve the C049C code, view freeze frame data, and check for additional codes. Follow the app's instructions to conduct a visual inspection of the traction control system components.

What vehicles are most commonly affected by C049C?

DTC C049C is frequently seen in vehicles like the 2015-2019 Ford Explorer and similar models from brands like Lincoln and Mercury that use the same chassis and systems.

How can I prevent C049C from happening again?

Regular maintenance, including checking and cleaning wheel speed sensors, ensuring wiring integrity, and timely addressing any dashboard warning lights, can help prevent the recurrence of the C049C code.

What is C049C?

DTC C049C is a diagnostic trouble code that indicates a malfunction within the vehicle's traction control system. This code is often triggered when the system detects an issue that affects its ability to maintain stability and traction on the road. In simpler terms, if you see this code, it means your vehicle's traction control is not functioning properly, which can lead to reduced safety while driving, especially in slippery conditions. This code is common in vehicles like the 2015-2019 Ford Explorer, where it may be associated with problems in the wheel speed sensors, the ABS module, or even issues with the powertrain control module (PCM). If left unresolved, this issue can lead to further complications, including increased stopping distances and potential loss of vehicle control. It’s essential to address this code promptly through professional diagnostic methods to ensure your vehicle’s safety features are fully operational.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C049C is present:

  • The check engine light remains illuminated, indicating a persistent issue that needs addressing.
  • You may notice the traction control warning light flashing intermittently during acceleration, especially on wet or slippery surfaces.
  • Drivers might experience a lack of traction or stability, especially when cornering or during sudden stops, which can feel like the car is skidding.
  • Unusual noises, such as grinding or clicking, may occur when the traction control system attempts to engage.
  • Increased wear on tires can be observed, as the system may not be able to compensate for wheel slip.

Possible Causes

Most common causes of C049C (ordered by frequency):

  1. The most common cause of C049C is a malfunctioning wheel speed sensor, which accounts for about 40% of cases. These sensors are crucial for the traction control system to monitor wheel speed and make necessary adjustments.
  2. Another common cause is issues with the ABS module, which may fail to communicate with the PCM, leading to a cascading failure of the traction control system.
  3. A third possible cause is wiring issues, such as damaged or corroded wires connected to the traction control system. Regular inspections can help prevent these issues.
  4. Less commonly, the powertrain control module itself may be malfunctioning, which is more serious and requires immediate attention.
  5. A rare cause could be software glitches within the vehicle's onboard systems, particularly if any recent updates or repairs were made to the vehicle's electronics.
