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. Scan and Clear Codes

Use the OBD-II scanner to read and record any diagnostic trouble codes (DTCs).
Clear the codes and see if the traction control light returns after a short drive.

3. Inspect Wheel Speed Sensors

Remove the wheels to access the wheel speed sensors.
Check for any visible damage or dirt on the sensors.
Clean the sensors using a soft cloth and brake cleaner if necessary.
Reinstall wheels and lower the vehicle.

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 disconnections.
If necessary, test the module function with a multimeter according to the manufacturer's specifications.

5. Brake Fluid and System Inspection

Check the brake fluid reservoir level; refill with the correct type of brake fluid if low.
Inspect brake lines and connections for any leaks or damage.
Test the brake pedal feel; if it feels spongy, the system may need bleeding.

6. Reconnect Battery

Reconnect the battery terminals, ensuring they are tight and secure.
Start the vehicle and check for the traction control light.
