Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Scan and Clear Codes

Use the OBD-II scanner to read any diagnostic trouble codes (DTC).
Note down any relevant codes that could indicate the source of the problem.
Clear the codes and see if the traction control light reappears after a test drive.

3. Inspect Wheel Speed Sensors

Remove the wheel and tire to access the wheel speed sensors.
Inspect each sensor for dirt, cracks, or loose connections.
Clean the sensors with a suitable cleaner if they are dirty.
Reconnect any loose wiring and ensure a secure fit.

4. Check Brake Pedal Switch

Locate the brake pedal switch under the dashboard.
Use a multimeter to test for continuity when the brake pedal is pressed.
If the switch is faulty, remove it and replace it with a new one.

5. Inspect ABS Module

Check the ABS module for any signs of damage or corrosion.
If any issues are found, remove the module following manufacturer guidelines.
Replace with a new or refurbished ABS module if necessary.
