Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to avoid electrical shorts.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and check the fluid level.
If low, add the recommended brake fluid (DOT 3 or 4 as specified in the owner's manual) until it reaches the full mark.
Reattach the cap securely.

3. Inspect ABS Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Check for any visible damage or dirt on the sensors.
Clean the sensors and mounting surfaces with a soft cloth.

4. Test ABS Control Module

Reconnect the battery.
Use the OBD-II scanner to clear any stored ABS codes.
Start the vehicle and check if the ABS light remains off.
If the light returns, further diagnostics on the ABS control module may be needed.

5. Replace Faulty Components (if necessary)

If any ABS sensor or the control module is found faulty, replace it:
- For sensor replacement: Unplug the old sensor, remove the mounting bolt, and install the new sensor.
- For control module replacement: Disconnect all wiring, remove mounting bolts, and install the new module, ensuring correct wiring connections.
