Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (sockets, wrenches), brake fluid.
Disconnect the vehicle battery to ensure safety during repairs.

2. Repair Faulty Wheel Speed Sensors

Access the Wheel Speed Sensors: Lift the vehicle securely and remove the wheel to gain access.
Disconnect the Sensor Connector: Carefully disconnect the electrical connector from the wheel speed sensor.
Remove the Sensor: Unscrew the sensor from its mounting point using the appropriate socket.
Install New Sensor: Position the new wheel speed sensor in place and secure it with the bolt.
Reconnect the Electrical Connector: Ensure the connector clicks into place firmly.

3. Repair or Replace ABS Module

Remove the ABS Module: Locate the ABS module, disconnect the electrical connectors, and unscrew it from its mounting.
Inspect for Damage: Check the module for any signs of physical damage or burnt components.
Replace with New Module: If damaged, install a new ABS module, ensuring it is seated properly and secured.
Reconnect Electrical Connectors: Attach all connectors to the new module, ensuring a snug fit.

4. Reset ABS System

Reconnect the Battery: Once repairs are made, reconnect the vehicle battery.
Clear Error Codes: Use the OBD-II scanner to clear any stored error codes in the ABS system.
Test the ABS Functionality: Perform a road test to ensure the ABS is functioning correctly without any warning lights.
