Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, clean rags.
Ensure the vehicle is on a flat surface, and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Fuses

Locate the fuse box under the dashboard and/or engine compartment.
Remove the cover and identify the ABS fuse using the diagram on the fuse box cover.
Use a multimeter to check for continuity; if the fuse is blown, replace it with one of the same amperage.

3. Inspect and Clean Wheel Speed Sensors

Remove the wheel corresponding to the ABS light (usually the front wheels).
Locate the ABS wheel speed sensor on the wheel hub assembly.
Inspect for dirt, debris, or damage; clean the sensor with a soft cloth if dirty.
Reconnect any disconnected wiring and ensure the connector is secure.

4. Brake Fluid Inspection

Locate the brake master cylinder and check the brake fluid level.
If the fluid is low, fill it with the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
Inspect for leaks in brake lines or connections, addressing any found.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminal securely.
Use the OBD-II scanner to clear any stored ABS codes.
Start the vehicle and monitor the ABS light status.
