Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts during repairs.

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the ABS wheel speed sensors at each wheel hub.
3. Disconnect the sensor wiring harness carefully.
4. Remove the sensor from its mounting bracket using the socket set (typically 10mm).
5. Clean the sensor tip with a soft cloth and electronic cleaner to remove any dirt or debris.
6. Reinstall the sensor, ensuring it is seated properly, and reconnect the wiring harness.

3. Check Brake Fluid Level

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level; if below the minimum mark, add the recommended brake fluid (DOT 3 or as specified in the owner's manual).
3. Inspect for any signs of leaks around brake lines and fittings.

4. Test Traction Control Switch

Sub-steps:
1. Locate the traction control switch on the dashboard (usually near the gear shift).
2. Use a multimeter to check for continuity when the switch is pressed.
3. If the switch is faulty, replace it with a new one.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any existing error codes related to the traction control system.
Start the vehicle and check if the traction control warning light is still illuminated.
