The C0744 code is commonly seen in Ford F-150s (2011-2014), Chevrolet Silverados (2014-2017), and GMC Sierras (2014-2017), among others. Checking for any recalls or technical service bulletins related to your vehicle can also be helpful.
How can I prevent C0744 from happening again?
Regular vehicle maintenance, including checking and cleaning electrical connections, inspecting sensors, and keeping the ABS system in good condition, can help prevent the recurrence of the C0744 code.
What is C0744?
The DTC code C0744 indicates a malfunction within the traction control system of your vehicle, primarily affecting models from Ford, Chevrolet, and GMC. This diagnostic trouble code suggests that the vehicle's onboard diagnostics have detected an issue with the traction control system's performance or functionality. In simple terms, this system helps your vehicle maintain grip on slippery surfaces by adjusting power to the wheels. When the C0744 code is triggered, it typically means that the traction control system is either not responding correctly or is completely disabled. Symptoms may include the traction control light illuminating on the dashboard, unusual wheel slip during acceleration, or decreased vehicle stability. This code is often associated with faulty wheel speed sensors, issues in the ABS module, or wiring problems. Ignoring this code can lead to compromised vehicle safety, especially in adverse weather conditions, making timely diagnosis and repair crucial.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0744 is present:
- The traction control warning light illuminates on the dashboard, indicating the system is not functioning properly.
- The vehicle experiences wheel slip during acceleration, especially on wet or icy roads, making it harder to maintain control.
- Drivers may notice reduced stability when cornering, particularly in adverse weather, leading to a less confident driving experience.
- Unusual noises or vibrations may occur during acceleration, suggesting a problem with the ABS or traction control components.
- In some cases, the vehicle's anti-lock braking system (ABS) may also be affected, leading to inconsistent braking performance.
Possible Causes
Most common causes of C0744 (ordered by frequency):
- The most common cause of the C0744 code is a faulty wheel speed sensor, which can occur in about 60% of cases. This sensor detects the rotational speed of each wheel and sends this data to the traction control system. If it fails, the system cannot function correctly.
- Another frequent culprit is a malfunctioning ABS module, which is responsible for controlling the traction control system. If this module fails, it can lead to a complete system shutdown.
- Wiring issues, such as damaged or corroded connectors, can also trigger the C0744 code. Regular inspections can help prevent these issues, especially in older vehicles.
- Less commonly, software bugs in the vehicle's control module could lead to false readings, resulting in the C0744 code being set.
- In rare cases, mechanical failures in the differential or axle assemblies may also cause the traction control system to malfunction.
