Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery negative terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors (if necessary)

Tools Required: Socket set, multimeter, torque wrench.
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel associated with the suspected faulty sensor.
3. Disconnect the wheel speed sensor connector.
4. Use a multimeter to check the sensor's resistance according to the specifications in the service manual.
5. If the sensor is faulty, remove the mounting bolt and replace it with a new sensor.
6. Reconnect the sensor and wheel, then lower the vehicle.

3. Check and Replace ABS Module (if necessary)

Tools Required: Socket set, brake line wrench, torque wrench.
Sub-steps:
1. Locate the ABS module under the hood.
2. Disconnect the electrical connectors from the ABS module.
3. Use a brake line wrench to carefully disconnect the brake lines from the ABS module.
4. Remove the mounting bolts securing the ABS module and take it out.
5. Install the new ABS module, securing it with the bolts and reconnecting the brake lines, ensuring they are torqued to specifications.
6. Reconnect the electrical connectors.

4. Refill Brake Fluid and Bleed Brakes

Tools Required: Brake fluid, brake bleeder kit, funnel.
Sub-steps:
1. Refill the brake fluid reservoir with the appropriate type of brake fluid.
2. Begin bleeding the brakes at the farthest wheel from the master cylinder and work towards the closest one.
3. Use a brake bleeder kit to remove any air bubbles from the system.
4. Ensure the brake fluid level remains full during the bleeding process.

5. Reconnect Battery and Clear Codes

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear any stored ABS error codes.
