Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is off.
Gather tools and parts needed for the repair.

2. Scan and Clear Codes

Use an OBD-II scanner to check for any stored trouble codes.
If codes are present, make a note of them, then clear the codes to see if the light reactivates.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connectors and remove the sensors using a socket set.
Clean any debris from the sensor and its mounting location.
Reinstall the sensors and connectors securely.

4. Check Brake Fluid and System

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid is at the proper level; if low, top off with the manufacturer-recommended fluid type.
Inspect for any signs of leakage around brake lines and components.

5. Inspect ABS Module

Locate the ABS module and check for any visible damage or loose connections.
Use the OBD-II scanner to test diagnostic codes related to the ABS system.
If necessary, replace the ABS module or its related components based on diagnostic findings.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test for continuity when the switch is pressed.
If defective, replace with a new switch.

7. Tire Inspection

Check tire pressure and inflate to the recommended levels if low.
Inspect tire tread depth and condition; replace tires if worn unevenly or excessively.
