Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and secure with wheel chocks.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel to access the wheel speed sensor.
Inspect the sensor for dirt or damage; clean if necessary.
Using a multimeter, test the sensor's resistance; replace if out of specification.

3. Check ABS Module

Tools Required: OBD-II scanner
Reconnect the battery terminal and power on the vehicle.
Use an OBD-II scanner to check for ABS module errors.
If errors are present, follow manufacturer guidelines to address specific issues.

4. Brake Fluid Inspection

Tools Required: Brake fluid tester, socket set
Remove the brake fluid reservoir cap and check fluid level.
Inspect for any signs of contamination or leaks.
If fluid is low or contaminated, replace with the appropriate brake fluid type (DOT 3 or DOT 4).

5. Traction Control Switch Test

Tools Required: Multimeter
Locate the traction control switch on the dashboard.
Test the switch with a multimeter to ensure it is functioning correctly; replace if faulty.
