Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, wheel chocks.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect Wheel Speed Sensors

a. Locate the wheel speed sensors at each wheel hub.
b. Clean any dirt or debris around the sensors using a soft brush.
c. Disconnect the sensor connector and use a multimeter to check for continuity.
d. If faulty, replace the wheel speed sensor with a new unit, ensuring to torque to manufacturer specifications.

3. Examine ABS Control Module

a. Locate the ABS control module under the hood or near the brake master cylinder.
b. Inspect wiring harnesses for damage or loose connections.
c. Clear any error codes using the OBD-II scanner and perform a system reset.
d. If issues persist, consider replacing the ABS control module.

4. Test Traction Control Switch

a. Locate the traction control switch on the dashboard.
b. Use a multimeter to test for continuity when the switch is pressed.
c. If the switch is faulty, replace it with a new one, ensuring proper installation.

5. Brake System Inspection

a. Check brake fluid levels in the master cylinder reservoir; top off if low.
b. Inspect brake pads and rotors for wear; replace if necessary.
c. Ensure brake lines are free of leaks and damage.

6. Tire Condition and Pressure Check

a. Inspect all tires for uneven wear or damage.
b. Use a tire pressure gauge to check pressure and inflate tires to the recommended PSI.
c. Rotate tires if necessary to ensure even wear and optimal traction.
