Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor wiring harness.
Use a multimeter to check for continuity in the sensor. Replace if faulty.

3. Check Brake Fluid and Lines

Tools Required: Brake fluid tester, wrench set.
Inspect the brake fluid reservoir for proper levels. Top off with the recommended fluid if low.
Check for any visible leaks in the brake lines and connections. Repair or replace as necessary.

4. Test ABS Module

Tools Required: OBD-II scanner.
Reconnect the battery and start the vehicle.
Use the OBD-II scanner to perform a self-test on the ABS module. Follow the scanner's prompts to diagnose any issues.

5. Verify Traction Control Switch Functionality

Tools Required: Multimeter.
Locate the traction control switch on the dashboard.
Use the multimeter to test the switch for proper activation. Replace the switch if it fails to operate.
