Solution

1. Preparation

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

2. Inspect and Replace ABS Fuse

Locate the fuse box (refer to the owner's manual for location).
Remove the ABS fuse using a fuse puller.
Inspect the fuse for a break; if damaged, replace it with a new fuse of the same amperage.

3. Examine and Replace Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the wiring harness from the sensor.
Remove the sensor from its mounting location (usually held by screws).
Clean the area around the sensor and install the new sensor.
Reconnect the wiring harness and repeat for all wheels.

4. Bleed the Brake System

Reconnect the negative battery terminal.
Fill the brake fluid reservoir with the recommended brake fluid type (DOT 3 or DOT 4).
Start bleeding the brake system using a brake bleeder kit or by having an assistant pump the brake pedal while you open and close the bleeder valves on each brake caliper, starting from the furthest from the master cylinder.
Ensure there are no air bubbles in the brake fluid.

5. Reset ABS System

Use an OBD-II scanner to clear any ABS fault codes.
Turn the ignition on without starting the engine and check for the ABS warning light.
