Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the vehicle to cool down before starting work.

2. Retrieve and Interpret Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve any stored codes related to the traction control system and note them for further analysis.

3. Inspect ABS Sensors

Locate the ABS sensors at each wheel.
Check for any visible damage to the sensor or wiring.
Clean the sensor and surrounding area of any debris if necessary.

4. Check Tire Pressure

Use a tire pressure gauge to measure the air pressure in each tire.
Inflate or deflate tires to match the recommended pressure listed on the driver’s door jamb.

5. Test Brake Pedal Switch

Locate the brake pedal switch above the brake pedal arm.
Use a multimeter to test the switch for continuity when the brake pedal is pressed.
Replace the switch if it is found to be faulty.

6. Clear Codes and Test Drive

Clear any codes using the OBD-II scanner.
Reconnect the battery and start the engine.
Perform a test drive to ensure the traction control light remains off and the system operates correctly.
