Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors on each wheel assembly.
2. Disconnect the electrical connectors from the wheel speed sensors.
3. Remove the mounting bolts securing the sensors and take out the old sensors.
4. Install new wheel speed sensors by reversing the removal steps.
5. Reconnect the electrical connectors securely.
Tools Required: Socket set, ratchet, torque wrench.

3. Check and Replace ABS Fuse

Sub-steps:
1. Locate the fuse box in the engine compartment.
2. Remove the cover and identify the ABS fuse using the diagram on the cover.
3. Inspect the fuse for continuity; replace it with a new fuse if blown.
4. Reinstall the fuse box cover.
Tools Required: Fuse puller or needle-nose pliers.

4. Brake Fluid Level Check

Sub-steps:
1. Locate the brake fluid reservoir on the master cylinder.
2. Check the fluid level against the minimum and maximum markers.
3. If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
Safety Warning: Brake fluid is corrosive; avoid contact with painted surfaces.
