Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Multimeter
- Socket set
- Torque wrench
- Screwdrivers
Safety Warnings:
- Disconnect the negative battery terminal before starting the repair.
- Allow the vehicle to cool down before working on the brake components.

2. Remove the Faulty ABS Sensor

Locate the ABS sensor: Identify the sensor mounted on the wheel hub or brake assembly.
Disconnect the wiring harness: Carefully unplug the ABS sensor connector.
Remove mounting bolts: Use a socket set to remove the bolts securing the ABS sensor to the wheel hub.
Extract the sensor: Gently pull the sensor out of its mounting location.

3. Install the New ABS Sensor

Position the new sensor: Insert the new ABS sensor into the mounting location.
Secure the sensor: Reinstall the mounting bolts and tighten them to the manufacturer’s specified torque value (typically around 10-15 ft-lbs).
Reconnect the wiring harness: Plug the ABS sensor connector back into place.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Erase error codes: Use the OBD-II scanner to clear any stored ABS codes.
Test the ABS system: Start the vehicle and perform a test drive to ensure the ABS warning light is off and the system is functioning correctly.
