Solution

1. Preparation

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

2. Scan for Error Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Record any trouble codes, particularly those related to the traction control system.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel assembly.
Check for physical damage, dirt buildup, or disconnection.
Clean or replace any damaged sensors. Ensure connections are secure.

4. Check Brake Fluid Level

Locate the brake fluid reservoir.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top up with the manufacturer-recommended brake fluid type (DOT 3 or DOT 4).

5. Inspect ABS Module and Wiring

Locate the ABS module, typically near the master cylinder.
Check the module for any signs of leaks or corrosion.
Inspect the wiring harness for frayed wires or loose connections and repair as necessary.

6. Reconnect Battery and Test Drive

Reconnect the battery terminal.
Start the engine and monitor dashboard lights.
Take the vehicle for a test drive, paying attention to traction control operation.
