Solution

1. Preparation

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

2. Scan for Error Codes

Reconnect the battery and plug in the OBD-II scanner.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner instructions to retrieve and note any error codes.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor on the brake assembly.
Remove any dirt or debris around the sensors.
Check the wiring for frays or disconnections.
Clean the sensor area with a soft cloth if necessary.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid level is within the recommended range (between the "MIN" and "MAX" marks).
If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).

5. Examine the ABS Module

Locate the ABS module, typically found near the master cylinder.
Inspect for any visible leaks or damage.
Use a multimeter to test the module for proper voltage and continuity according to the service manual specifications.

6. Reconnect and Test

Reconnect the negative battery terminal.
Start the engine and check if the traction control light remains illuminated.
If the light is still on, clear the error codes using the OBD-II scanner and take the vehicle for a test drive to see if it returns.
