Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, brake fluid.
Safety Warnings: Disconnect the battery before starting work on electrical systems.

2. Check Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle and secure it with jack stands.
2. Locate the wheel speed sensors on each wheel hub.
3. Visually inspect for physical damage or disconnections.
4. Use a multimeter to check the sensor's resistance (should be within manufacturer specifications).
5. Replace any faulty sensors with OEM parts.

3. Inspect ABS Module and Wiring

Sub-steps:
1. Locate the ABS module, typically found near the brake master cylinder.
2. Inspect wiring harnesses for frays or corrosion.
3. Use a multimeter to test for continuity and proper voltage at the ABS module.
4. If issues are detected, repair or replace wiring as needed.

4. Brake System Check

Sub-steps:
1. Check the brake fluid level; refill if low.
2. Inspect brake lines for leaks or damage.
3. If leaks are found, replace the damaged components.
4. Bleed the brake system to ensure no air is present.

5. Tire Inspection

Sub-steps:
1. Check each tire for proper inflation and tread depth.
2. Replace any tires that are worn or damaged.
3. Ensure all tires match in size and type to prevent traction differences.
