Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety.
Allow the vehicle to cool down if it has been running.

2. Inspect ABS Sensors

Locate the ABS sensors at each wheel hub.
Remove any dirt or debris from the sensors using a clean cloth.
Check the wiring harness for fraying or damage.
Ensure that the sensors are securely mounted.

3. Test and Replace Wheel Speed Sensors (if necessary)

Use a multimeter to test the resistance of each wheel speed sensor; refer to the specifications in the service manual.
If a sensor is outside of specifications, remove the faulty sensor:
- Unscrew the mounting bolt using a socket set.
- Carefully pull out the sensor from its housing.
Install the new wheel speed sensor:
- Insert the sensor into the housing and tighten the mounting bolt to the manufacturer's torque specification.

4. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, add the appropriate brake fluid type (usually DOT 3 or DOT 4).
If fluid is contaminated, consider flushing the brake lines.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any trouble codes.
Start the vehicle and check if the traction control light remains off.
