Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather all necessary tools and parts.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, fill with manufacturer-recommended brake fluid to the correct level.
Close the reservoir cap securely.

3. Inspect ABS Sensors

Safely lift the vehicle using a jack and secure it with jack stands.
Locate each wheel's ABS sensor; typically mounted near the brake rotor.
Inspect the sensors and wiring for any signs of damage, dirt, or corrosion.
Clean any debris or dirt from the sensors using a soft cloth.

4. Read and Clear Trouble Codes

Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner’s instructions to read fault codes related to the ABS system.
If codes are present, note them down. Clear the codes using the scanner's erase function.
