Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Disconnect the wiring harness from the sensor.
3. Remove the sensor using a socket set (typically a 10mm socket).
4. Clean the mounting hole and ensure no debris is present.
5. Install the new sensor, tightening it to the manufacturer’s specifications (usually 7-11 ft-lbs).
6. Reconnect the wiring harness securely.

3. Check and Refill Brake Fluid

Sub-steps:
1. Locate the master cylinder reservoir and remove the cap.
2. Inspect the brake fluid level; if low, add the appropriate DOT fluid (check owner’s manual for specifications).
3. Replace the cap securely after filling.

4. Replace ABS Fuse if Necessary

Sub-steps:
1. Locate the fuse box (generally under the dashboard or in the engine bay).
2. Identify the ABS fuse using the diagram on the fuse box cover.
3. Remove the fuse using fuse pullers or needle-nose pliers.
4. Inspect the fuse for continuity; replace it with a new one if blown (use the same amperage).

5. Reconnect Battery and Reset ABS Light

Sub-steps:
1. Reconnect the negative battery terminal and tighten it securely.
2. Use the OBD-II scanner to clear any stored ABS codes.
3. Start the engine and check if the ABS light is still illuminated.
