Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensors using a soft cloth.
Ensure the wiring harness is securely connected and not frayed.

3. Check Brake Fluid and System

Open the hood and locate the brake fluid reservoir.
Check the fluid level; top off with the appropriate brake fluid if low.
Inspect brake lines for leaks or wear that may affect traction control.

4. Examine ABS Control Module

Locate the ABS control module typically under the hood or near the brake booster.
Inspect the module for any visible signs of damage or corrosion.
Use a multimeter to check for proper voltage and ground continuity.

5. Test Traction Control Switch

Locate the traction control button, usually on the center console.
Disconnect the switch from the wiring harness and test it with a multimeter for continuity.
Replace the switch if it fails the continuity test.

6. Reconnect Battery and Clear Codes

Once all inspections and repairs are completed, reconnect the battery.
Use the OBD-II scanner to clear any stored error codes.
Start the vehicle and check that the traction control light is off.
