Solution

1. Preparation

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

2. Scan for Error Codes

Use an OBD-II scanner to retrieve any error codes.
Document the codes for reference.

3. Inspect Wheel Speed Sensors

Remove the wheel and tire assembly to access the wheel speed sensors.
Visually inspect sensors for any physical damage or dirt buildup.
Clean sensors with an appropriate cleaner if necessary.
Reconnect any loose connectors and ensure they are secure.

4. Check ABS System

Inspect the ABS control module and wiring harness for any visible damage.
If codes indicate an ABS issue, follow up by testing the ABS pump motor and module according to manufacturer specifications.

5. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the brake fluid level and condition; top off if low with the recommended brake fluid type (usually DOT 3 or DOT 4).
If the fluid is contaminated, consider a brake fluid flush.

6. Inspect Traction Control Switch

Locate the traction control switch on the dashboard.
Test the switch using a multimeter to ensure it is functioning correctly.
Replace the switch if it is defective.

7. Reconnect Battery and Clear Codes

Reconnect the battery.
Clear any error codes using the OBD-II scanner.
Start the vehicle and check if the traction control light remains off.
