Solution

1. Preparation

Gather necessary tools and ensure the vehicle is on a flat surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Scan for Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Record any trouble codes that appear and address them accordingly based on their descriptions.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensors.
Check the wiring harness connected to each sensor for loose connections or damage.
Replace any damaged sensors as necessary.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Inspect the brake fluid level; if low, top it up with the recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, flush the brake system and replace the fluid.

5. Test Traction Control Switch

Locate the traction control switch, usually near the gear shifter or on the dashboard.
Press the switch to toggle the traction control system on and off.
If the switch is malfunctioning, replace it with a new one.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any trouble codes after repairs.
