Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, tire pressure gauge.
Ensure the vehicle is on a flat surface and the engine is off. Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Visually inspect the sensor for damage or corrosion.
4. Use a multimeter to test the sensor's resistance; it should be within the manufacturer's specifications.
5. Clean any debris or dirt from the sensor and connector.

3. Check Brake Fluid Level

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
3. If low, top off with the recommended brake fluid (DOT 3 or DOT 4).
4. Check for any visible leaks around the brake lines and calipers.

4. Examine ABS Module

Sub-steps:
1. Locate the ABS module, usually found near the brake master cylinder.
2. Check for loose connections or damaged wiring.
3. Using the OBD-II scanner, clear any fault codes related to the ABS.
4. Reconnect the battery and turn the ignition to the "ON" position without starting the engine to check for warning lights.

5. Verify Tire Condition and Pressure

Sub-steps:
1. Inspect all tires for uneven wear, damage, or low tread depth.
2. Use a tire pressure gauge to check the pressure of each tire.
3. Inflate tires to the recommended pressure listed on the driver’s side door jamb.
4. Rotate tires if necessary, following the vehicle's maintenance schedule.
