Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, jack stands.
Ensure the vehicle is parked on a flat surface and the engine is off. Disconnect the battery negative terminal for safety.

2. Address Error Codes

Sub-steps:
1. Connect the OBD-II scanner and retrieve any error codes related to the traction control system.
2. If codes are present, note them down for reference.
3. Clear the codes and perform a test drive to see if they reappear. If they do, proceed with specific troubleshooting for those codes.

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

Sub-steps:
1. Lift the vehicle using the jack and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensors.
3. Disconnect the sensor wiring harness and remove the sensor using the appropriate socket size.
4. Inspect the sensor for wear or damage; replace if necessary.
5. Reinstall the new sensor, reconnect the wiring harness, and reattach the wheel.

4. Check and Top Off Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level against the minimum and maximum marks.
3. If low, top off with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).
4. Reconnect the battery terminal.

5. Test Drive and Monitor

Sub-steps:
1. Start the vehicle and ensure that the traction control warning light is off.
2. Conduct a test drive to evaluate the performance of the traction control system.
3. Monitor for any warning lights or unusual behavior during the drive.
