Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat, stable surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Sub-steps:
- Remove the wheel on which the sensor is being inspected.
- Unplug the sensor connector and remove the mounting bolts.
- Install the new wheel speed sensor and secure it with the bolts.
- Reconnect the sensor connector.
- Repeat for other wheels if necessary.

3. Check and Replace ABS Fuses

Open the fuse box and locate the ABS fuse.
Sub-steps:
- Remove the fuse using a fuse puller.
- Inspect the fuse to check for continuity.
- If blown, replace it with a fuse of the same amperage.
- Close the fuse box securely.

4. Brake Fluid Check and Top Off

Locate the master cylinder reservoir under the hood.
Sub-steps:
- Remove the cap and check fluid level; it should be between the "MIN" and "MAX" lines.
- If low, add the recommended brake fluid type (usually DOT 3 or DOT 4).
- Re-secure the cap after filling.

5. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light is still illuminated.
Conduct a test drive to ensure proper braking performance and monitor for the ABS light.
