Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent accidental electrical issues.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter
Sub-steps:
1. Locate the wheel speed sensors on each wheel hub assembly.
2. Disconnect the electrical connector from the sensor.
3. Remove the mounting bolts and carefully take out the sensor.
4. Use the multimeter to test the sensor's resistance; replace if out of specification.
5. Install the new wheel speed sensor, torque mounting bolts to manufacturer specifications.
6. Reconnect the electrical connector.

3. Check and Replace ABS Fuse

Tools Required: Fuses, fuse puller
Sub-steps:
1. Locate the fuse box (usually under the dashboard or hood).
2. Identify the ABS fuse using the diagram on the fuse box cover.
3. Remove the fuse using a fuse puller and check for continuity.
4. Replace the fuse with one of the same amperage if blown.

4. Inspect and Repair ABS Module

Tools Required: Scan tool, socket set
Sub-steps:
1. Use the OBD-II scanner to check for ABS module error codes.
2. If codes indicate a fault, remove the ABS module from the vehicle.
3. Inspect the module for signs of corrosion or damage.
4. Clean the connectors and reinstall or replace the module as needed.

5. Refill and Bleed Brake Fluid

Tools Required: Brake fluid, brake bleeder kit
Sub-steps:
1. Check the brake fluid reservoir and refill with the appropriate type of brake fluid.
2. Use a brake bleeder kit to bleed air from the brake lines, ensuring there are no air pockets in the system.
3. Ensure the brake pedal feels firm after bleeding.
