Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the negative battery terminal to ensure safety.

2. Addressing Error Codes

Sub-step 1: Connect the OBD-II scanner to the vehicle's diagnostic port.
Sub-step 2: Retrieve and note any DTCs related to the traction control system.
Sub-step 3: Clear the codes and see if the traction control light reappears after a test drive.

3. Inspect Wheel Speed Sensors

Sub-step 1: Locate the wheel speed sensors on each wheel hub.
Sub-step 2: Clean the sensors gently with a soft cloth to remove dirt or debris.
Sub-step 3: Inspect wiring for any signs of damage or corrosion.
Sub-step 4: If damaged, replace the wheel speed sensor with a new one.

4. Check Brake Fluid Level

Sub-step 1: Open the hood and locate the brake fluid reservoir.
Sub-step 2: Inspect the fluid level; if low, top up with the recommended brake fluid (DOT 3 or DOT 4).
Sub-step 3: If the fluid is contaminated, perform a brake fluid flush and replace it.

5. Test Traction Control Switch

Sub-step 1: Locate the traction control switch on the dashboard.
Sub-step 2: Check for physical damage or dirt buildup.
Sub-step 3: Use a multimeter to test the switch for continuity; replace if faulty.

6. Reconnect Battery and Test Drive

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the vehicle and perform a test drive to monitor the traction control light.
Sub-step 3: Observe if the light remains off and the system functions correctly.
