Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake cleaner, wire brush, basic hand tools.
Safety Warnings: Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Fault Codes

Sub-steps:
1. Use the OBD-II scanner to read and note the ABS codes.
2. Research the codes to determine the affected components and necessary repairs.

3. Check and Replace ABS Fuse

Sub-steps:
1. Locate the fuse box (usually under the dashboard or hood).
2. Identify the ABS fuse using the fuse diagram.
3. Remove the fuse and inspect it for continuity.
4. Replace the fuse if it's blown. Ensure you use the correct amp rating.

4. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Locate the wheel speed sensors on each wheel hub.
3. Disconnect the sensor connectors and inspect for damage or dirt.
4. Clean the sensor with brake cleaner and a wire brush if necessary.
5. Reconnect the sensors securely.

5. Inspect ABS Control Module

Sub-steps:
1. Locate the ABS control module (often near the master cylinder).
2. Visually inspect the connections for corrosion or loose wires.
3. Clean any corrosion with a wire brush and reconnect securely.

6. Brake Fluid Check

Sub-steps:
1. Check the brake fluid reservoir for proper fluid level.
2. If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
3. Inspect for any leaks in the brake lines or fittings.
