Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Gather tools and parts needed for the repair.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any error codes related to the traction control system for further analysis.

3. Inspect Wheel Speed Sensors

Jack up the vehicle and remove the wheels if necessary for better access.
Locate the wheel speed sensors on each wheel hub.
Check for any damage to the wiring or connector, and clean any dirt or debris from the sensor.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level, topping it off with the correct brake fluid type if low.
Look for any leaks in the brake lines or around the master cylinder.

5. Test Traction Control Switch

Locate the traction control switch, typically found on the dashboard or center console.
Use a multimeter to test for continuity while pressing the switch.
Replace the switch if it fails the continuity test.

6. Inspect ABS System

Perform a visual inspection of the ABS module and associated wiring for any signs of damage.
If necessary, use a scan tool to run a diagnostic on the ABS and check for any stored trouble codes.
Repair or replace any faulty components as indicated by the diagnostic results.
