Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Safety Warnings: Disconnect the vehicle battery before beginning work to prevent electrical shock and accidental deployment of airbag systems.

2. Address Error Codes

Use the OBD-II scanner to retrieve the ABS-related error codes.
Note the specific codes for further troubleshooting and repairs.

3. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Disconnect the electrical connector from the wheel speed sensor.
4. Remove the sensor bolt using a socket set and extract the sensor.
5. Inspect the sensor for dirt and damage; clean or replace as necessary.
6. Reinstall the new or cleaned sensor, ensuring it is properly secured and connected.

4. Check and Replace ABS Fuse

Sub-steps:
1. Locate the fuse box, typically found under the dashboard or in the engine bay.
2. Identify the ABS fuse using the fuse diagram.
3. Remove the fuse and check for continuity using a multimeter; replace if blown.

5. Inspect and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; if low, add the recommended brake fluid type.
3. Inspect for any leaks in the brake lines or around the reservoir.
4. Tighten any loose connections and replace any damaged brake lines.

6. Test ABS Module and Pump

Sub-steps:
1. Reconnect the battery and turn on the ignition without starting the engine.
2. Use the multimeter to test the ABS module for proper voltage and ground.
3. Listen for the ABS pump operation when the ignition is turned on.
4. If the module is faulty, replace it according to manufacturer specifications.
