Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor and mounting area using a clean cloth.
Check the wiring harness for any signs of wear or damage.
Reconnect the sensor securely.

3. Check ABS Fuses and Relays

Locate the fuse box under the dashboard or engine bay.
Remove the ABS fuses one at a time and inspect for continuity using a multimeter.
Replace any blown fuses with the correct amperage.
Check the relays for proper operation and replace if necessary.

4. Test Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the recommended brake fluid type (DOT 3 or DOT 4) as specified in the owner’s manual.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes after repairs.
Start the vehicle and check if the ABS light remains off.
