Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Replace Faulty Wheel Speed Sensor (if needed)

Identify the wheel speed sensor that triggered the ABS code.
Lift the vehicle with a jack and support it with jack stands.
Remove the wheel to access the sensor.
Disconnect the electrical connector from the sensor.
Remove the mounting bolt(s) securing the sensor and pull it out of the hub assembly.
Install the new wheel speed sensor, ensuring it is seated properly.
Reattach the mounting bolt(s) and torque to the manufacturer's specifications (typically around 7-10 ft-lbs).
Reconnect the electrical connector.

3. Replace ABS Module (if needed)

Locate the ABS module, typically found near the brake master cylinder.
Disconnect the electrical connectors from the ABS module.
Remove the mounting bolts securing the ABS module and take it out.
Install the new ABS module and secure it with the mounting bolts (torque to specifications).
Reconnect the electrical connectors.

4. Refill and Bleed Brake System

Check the brake fluid reservoir and refill it with the appropriate type of brake fluid (usually DOT 3 or DOT 4).
Bleed the brake system to remove any air trapped in the lines by starting with the wheel farthest from the master cylinder and working toward the closest.
Use a brake bleeder kit to assist in this process, ensuring all air bubbles are expelled.

5. Reset ABS Light

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS error codes.
Start the vehicle and check if the ABS light is still illuminated.
