Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor area.
Check the wiring and connectors for any signs of damage or corrosion.
If damaged, replace the wheel speed sensor with a new one.

3. Check Brake Fluid and System

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; top off with the recommended brake fluid type if low.
Check for visible leaks in brake lines and connections; repair as necessary.

4. Verify Tire Pressure

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to the recommended pressure as specified in the owner's manual.

5. Inspect ABS Module

Locate the ABS module in the engine compartment.
Check for loose or damaged wiring and connectors.
If necessary, test the ABS module's functionality with a multimeter and replace if found defective.
