Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid.
Ensure the vehicle is parked on a flat surface.
Disconnect the negative terminal of the car battery to prevent electrical shorts.

2. Use OBD-II Scanner

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 and clear the ABS codes.
If any codes are present, note them for further diagnosis before clearing.

3. Inspect ABS Components

Reconnect the battery.
Check the ABS wheel speed sensors for dirt or damage by visually inspecting each corner of the vehicle.
Clean the sensors gently with a soft cloth if dirty.
Ensure all wiring is intact, with no frayed or broken connections.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Ensure the fluid level is above the minimum mark; fill with the appropriate brake fluid if needed.
Close the reservoir cap securely after checking the fluid.

5. Final Steps

Start the vehicle and allow it to run for a few minutes.
Check if the ABS warning light is still illuminated.
If the light is off, the reset was successful; if the light persists, further diagnosis may be needed.
