Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, basic hand tools
Disconnect the negative battery terminal to ensure safety before working on electrical components.
Allow the vehicle to cool down if it has been recently operated.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor connectors and inspect for corrosion or damage.
Use a multimeter to check the resistance of each sensor (normally around 1,000-2,000 ohms).
Replace any defective sensors with new OEM parts.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
Inspect brake lines for leaks and ensure there is no contamination.

4. Test Traction Control Switch

Locate the traction control switch, typically near the center console.
Check for proper function by pressing the switch and observing any changes in the dashboard light.
Replace the switch if it is faulty or unresponsive.

5. Inspect ABS Module and Wiring

Locate the ABS module under the hood.
Check the electrical connectors for corrosion or loose connections.
Use a multimeter to test for proper voltage at the module (consult service manual for specifications).
Repair or replace any damaged wiring harnesses leading to the module.

6. Reset System

After addressing any issues found, reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes.
Perform a test drive to ensure the traction control light does not re-illuminate.
