Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Retrieve and Clear Codes

Use the OBD-II scanner to retrieve any error codes.
Write down any codes, as they will help in diagnosing the issue.
Clear the codes using the scanner and check if the traction control light returns after a test drive.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor connector and check for corrosion or loose connections.
Clean the sensor and connector with electrical contact cleaner.
Reconnect and secure the sensor properly.

4. Check ABS Module

Locate the ABS module under the hood or near the brake master cylinder.
Inspect the wiring harness for any signs of wear or damage.
If codes indicate a fault, consider replacing the ABS module.

5. Brake Fluid Inspection

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the minimum and maximum marks.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4).
If the fluid is dark or contaminated, consider flushing the brake system.

6. Traction Control Switch Testing

Locate the traction control switch on the dashboard.
Test the switch using a multimeter to ensure it operates correctly.
Replace the switch if it shows no continuity when pressed.

7. Tire Condition Check

Visually inspect all four tires for tread wear and proper inflation.
Inflate tires to the manufacturer-recommended pressure if necessary.
Replace any tires that are excessively worn.
