Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid any electrical issues while working.
Tools Required: OBD-II scanner, socket set, multimeter.

2. Check Wheel Speed Sensors

Remove the wheel to gain access to the wheel speed sensors.
Inspect the sensors for dirt, damage, or loose connections; clean or replace as necessary.
Reinstall the wheel and ensure it is torqued to the manufacturer’s specifications.

3. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
Replace the switch if it fails the continuity test.

4. Inspect ABS System

Use an OBD-II scanner to retrieve any ABS-related fault codes.
If faults are present, inspect ABS wiring and connectors for damage.
Test the ABS pump and module with a multimeter; replace if faulty.

5. Check Brake Fluid Levels

Open the hood and check the brake fluid reservoir.
If fluid is low, top it up with the recommended brake fluid type.
Inspect for any leaks in the brake lines or connections.
