Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Unplug the connector from the wheel speed sensor.
4. Remove the mounting bolts securing the sensor and take it out.
5. Install the new wheel speed sensor by reversing the removal steps.
6. Reconnect the electrical connector and ensure it is secured.

3. Check and Replace ABS Control Module

Sub-steps:
1. Locate the ABS control module, typically found near the brake master cylinder.
2. Disconnect the electrical connectors from the module.
3. Remove the mounting bolts and take out the old module.
4. Install the new ABS control module and secure it with bolts.
5. Reconnect the electrical connectors ensuring a tight fit.

4. Bleed the Brake System

Sub-steps:
1. Refill the brake fluid reservoir with the recommended brake fluid type.
2. Start from the wheel farthest from the master cylinder (usually the rear passenger).
3. Use a brake bleeder tool or have an assistant pump the brake pedal.
4. Open the bleeder valve to allow air and old fluid to escape, then close the valve before releasing the pedal.
5. Repeat this process for each wheel until no air bubbles are seen.

5. Reconnect Battery and Reset ABS Light

Sub-steps:
1. Reconnect the battery terminals, ensuring they are tight.
2. Use the OBD-II scanner to clear any stored fault codes.
3. Start the vehicle and check if the ABS warning light is off.
