Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Visually inspect the sensor for damage, dirt, or disconnection.
4. Use a multimeter to check the resistance of the sensor; compare readings to manufacturer specifications.
5. Clean the sensor and surrounding area if dirt is present.

3. Check Brake Fluid Level

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Inspect the fluid level; it should be between the minimum and maximum marks.
3. If low, top off with the appropriate brake fluid type as specified in the owner's manual.

4. Examine ABS Module

Sub-steps:
1. Locate the ABS module, usually near the brake master cylinder.
2. Inspect for any visible leaks or electrical connections that may be loose or corroded.
3. Clear any fault codes that may have been identified during the initial scan.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and lower the vehicle.
2. Reconnect the battery.
3. Start the vehicle and check if the traction control light is still illuminated.
4. Perform a test drive to ensure the traction control system is functioning properly.
