Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery cable to prevent electrical shorts.
Allow the vehicle to cool if recently driven.
Tools required: OBD-II scanner, socket set, multimeter.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Clean the sensor area with a cloth to remove debris.
3. Disconnect the electrical connector and inspect for damage.
4. Use a multimeter to check the sensor's resistance according to specifications (usually 1,000 to 2,000 ohms).
5. Replace any faulty sensors.

3. Check ABS Module

Sub-steps:
1. Locate the ABS module under the hood.
2. Visually inspect for corrosion or physical damage.
3. Check the electrical connections to ensure they are secure.
4. If necessary, use a multimeter to test voltage and ground supply to the module.
5. Replace the ABS module if it fails testing.

4. Verify Yaw Rate Sensor

Sub-steps:
1. Locate the yaw rate sensor, typically found under the center console or dashboard.
2. Inspect the sensor for loose connections or physical damage.
3. Use a scan tool to check for yaw rate sensor data and calibration status.
4. Replace the sensor if it does not provide accurate readings.

5. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the negative battery cable.
2. Use an OBD-II scanner to clear any stored trouble codes.
3. Start the vehicle and check if the traction control light remains off.
