Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, tire pressure gauge
Safety Warnings: Ensure the vehicle is on a flat surface and the engine is off before performing inspections.

2. Repair Faulty Wheel Speed Sensors

Lift the Vehicle: Use a jack to raise the vehicle and support it securely on jack stands.
Remove Wheel: Take off the wheel corresponding to the faulty sensor (if identified in diagnostics).
Disconnect Sensor Connector: Unplug the electrical connector from the wheel speed sensor.
Remove Sensor: Unscrew the sensor from its mount and take it out.
Install New Sensor: Place the new wheel speed sensor in position and secure it with screws.
Reconnect Connector: Plug the electrical connector back onto the new sensor.
Reinstall Wheel: Put the wheel back on and lower the vehicle.

3. Repair or Replace ABS Module

Locate ABS Module: Find the ABS module, typically located near the brake master cylinder.
Check Connections: Ensure all electrical connectors are secure and free from corrosion.
Test Module: Use a multimeter to test for proper voltage and ground at the ABS module.
Replace Module if Necessary: If the module is faulty, remove it by unscrewing the mounting bolts and disconnecting the hydraulic lines. Install a new ABS module and reattach the hydraulic lines securely.
