Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and ensure the engine is off.
  • Disconnect the negative battery terminal to prevent electrical shocks.
2. Scan and Record Trouble Codes
  • Use the OBD-II scanner to retrieve any stored trouble codes.
  • Document the codes for reference during repairs.
3. Inspect ABS Wheel Speed Sensors
  • Locate each wheel speed sensor (usually mounted near the brake assembly).
  • Clean any debris or dirt around the sensor and connector.
  • Check for wire damage or loose connections.
  • Replace any faulty sensors.
4. Check Brake Fluid Level
  • Open the hood and locate the brake fluid reservoir.
  • Ensure fluid is at the recommended level; top off with the correct type of brake fluid if necessary.
  • Inspect for leaks in the brake lines or around the master cylinder.
5. Inspect Brake Pedal Switch
  • Locate the brake pedal switch above the brake pedal.
  • Ensure the switch is properly aligned and functioning; test with a multimeter if necessary.
  • Replace the switch if it is found defective.
6. Check Fuses and Relays
  • Locate the fuse box (usually under the dashboard or in the engine bay).
  • Identify the fuse related to the traction control system (refer to the owner's manual).
  • Inspect the fuse for continuity and replace if blown.
  • Test the relay for proper operation using a multimeter.
7. Reconnect Battery and Clear Codes
  • Reconnect the negative battery terminal.
  • Use the OBD-II scanner to clear any stored trouble codes.
  • Start the vehicle and check if the traction control light is still illuminated.
