Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensors and wiring connectors using a clean cloth.
If damaged, replace the sensors with new ones.

3. Check ABS Module and Wiring

Inspect the ABS module for signs of corrosion or damage.
Examine the wiring harness connected to the ABS module for fraying or disconnections.
Repair or replace damaged wiring as necessary.

4. Verify Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Check the fluid level; if low, top it up with the recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush and replace with fresh fluid.

5. Test Traction Control Switch

Locate the traction control switch, typically found on the center console.
Use a multimeter to test the switch for continuity; replace it if it is faulty.

6. Tire Inspection

Check each tire for proper inflation using a tire pressure gauge.
Inspect tread depth and overall tire condition; replace tires that are worn or damaged.
