Solution

1. Preparation

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

2. Inspect and Replace ABS Wheel Speed Sensors

Tools Required:
- Socket set
- Torque wrench
- Multimeter
Sub-steps:
1. Locate the ABS wheel speed sensors at each wheel hub.
2. Disconnect the electrical connector from the sensor.
3. Remove the sensor using the appropriate socket.
4. Measure the resistance of the sensor with a multimeter; replace if out of specification.
5. Install the new wheel speed sensor, ensuring it is properly seated.
6. Reconnect the electrical connector and torque the sensor to the manufacturer's specifications.

3. Check and Replace ABS Fuse

Tools Required:
- Fuse puller or needle-nose pliers
Sub-steps:
1. Locate the fuse box (typically under the dashboard or in the engine compartment).
2. Identify the ABS fuse using the diagram on the fuse box cover.
3. Remove the fuse and check for continuity; replace if blown.
4. Reinstall the new fuse and ensure it is seated properly.

4. Check Brake Fluid Level

Tools Required:
- Brake fluid
Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Inspect the fluid level; if low, refill with the recommended type of brake fluid.
3. Check for any leaks in the brake lines or around the reservoir.
