Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Remove the wheel covers or hub caps if applicable.
Use a socket set to remove the wheel lug nuts and take off the wheels.
Locate the wheel speed sensors at each wheel hub.
Clean the sensors and their connectors using electrical cleaner.
Reinstall the wheels and lug nuts, tightening them to the manufacturer’s specifications (typically 80-100 ft-lbs).

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4 as applicable).
Reconnect the battery.

4. Test ABS Module

Reconnect the battery and turn on the ignition without starting the engine.
Use the OBD-II scanner to check for any ABS-related trouble codes.
If codes are present, repair the indicated issues; if not, proceed to test drive.

5. Tire Inspection

Check each tire for proper inflation and ensure they are all at the same pressure (refer to the manufacturer's recommended tire pressure).
Inspect the tread depth; replace any tires that are worn or unevenly bald.
