Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheels to gain access to the wheel speed sensors.
Clean the sensors and the mounting area to remove any debris.
Use a multimeter to test the sensor's resistance; compare readings to manufacturer specifications.
Replace any faulty sensors.

3. Check Brake Fluid Level

Inspect the brake fluid reservoir for proper fluid level.
If low, top off with the recommended brake fluid type (usually DOT 4).
Look for signs of leaks in brake lines or around the master cylinder.

4. Tire Inspection

Check all tires for proper inflation and tread depth.
Rotate or replace tires as necessary to ensure they are in good condition.

5. Examine ABS Module

Tools Required: Torque wrench, electrical cleaner
Inspect the ABS module and connections for corrosion or loose wiring.
Clean any corrosion and tighten connections securely.
Reconnect the battery and clear any codes from the OBD-II scanner.
