Solution

1. Preparation

Gather necessary tools and parts. Make sure the vehicle is parked on a flat surface and the engine is off.
Tools Required: OBD-II scanner, socket set, multimeter, wheel chocks, safety glasses.

2. Retrieve Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner instructions to read and record any trouble codes related to the traction control system.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the wheel speed sensors.
Disconnect the sensor wiring harness and visually inspect the sensor and wiring for damage.
Use a multimeter to check the resistance of the sensors; replace any faulty sensors.

4. Check Brake Fluid and System

Inspect the brake fluid reservoir to ensure the fluid level is adequate.
If low, top off with the manufacturer-recommended brake fluid.
Check brake lines for any signs of leaks or damage and repair as necessary.

5. Examine Traction Control Module

Locate the traction control module, usually found near the ABS module.
Inspect wiring and connectors for corrosion or damage.
If no visible issues are found, consider testing or replacing the module if diagnostic codes indicate failure.

6. Test Drive

Reassemble any disassembled components and lower the vehicle.
Start the engine and take the vehicle for a test drive to verify if the traction control light remains off and the system functions correctly.
