Solution

1. Preparation

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

2. Inspect and Replace ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the wheel for better access if necessary.
Disconnect the sensor connector and remove the mounting bolts.
Install the new sensor in reverse order, ensuring it is securely fastened.
Reconnect the sensor connector.

3. Inspect and Replace ABS Fuse

Locate the fuse box; refer to the owner's manual for the specific fuse related to the ABS system.
Remove the fuse using a fuse puller.
Inspect the fuse; replace it if it is blown with one of the same amperage rating.

4. Check and Top Off Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, remove the cap and add the appropriate brake fluid (DOT 4).
Replace the cap securely.

5. Inspect ABS Control Module

Locate the ABS control module, typically found near the master cylinder.
Visually inspect for corrosion, loose connections, or damaged wiring.
If damaged, replace the module according to the manufacturer's specifications.

6. Test ABS Functionality

Reconnect the battery and start the vehicle.
Use the OBD-II scanner to clear any error codes.
Test drive the vehicle to confirm that the ABS light is no longer illuminated and the system operates correctly.
