my Ford Mustang S650 (2024-Present) traction light is on, what does it mean?

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, basic hand tools, brake cleaner.
• Ensure the vehicle is parked on a level surface and the engine is turned off. Disconnect the battery to prevent any electrical issues while working on the system.

2. Inspect Wheel Speed Sensors

• Remove the wheel covers or tires if necessary for access.
• Locate each wheel speed sensor at the wheel hub assembly.
• Clean the sensors and surrounding areas with brake cleaner to remove any debris.
• Check the wiring harness for any signs of damage or disconnection.
• Reconnect any loose connections and ensure that all sensors are securely mounted.

3. Check Brake System Components

• Inspect brake pads and rotors for wear and proper function.
• Verify that the ABS module is functioning correctly by checking for any visible damage or leaks.
• If any issues are found, replace the affected components using the manufacturer’s specifications.

4. Test Throttle Position Sensor

• Reconnect the battery and start the vehicle.
• Use a multimeter to test the throttle position sensor's voltage output while slowly pressing the accelerator pedal.
• Compare the readings with the manufacturer’s specifications. If the readings are outside the specified range, replace the throttle position sensor.

5. Clear Error Codes

• After repairs, use the OBD-II scanner to clear any stored error codes.
• Take the vehicle for a short test drive to ensure the traction control light remains off.
