Solution

1. Preparation

Gather necessary tools and components.
Disconnect the negative battery terminal to prevent electrical shocks.
Ensure the vehicle is on a level surface and properly secured with jack stands if needed.

2. Remove the ABS Module

Locate the ABS module, typically situated near the brake master cylinder.
Disconnect the wiring harness connected to the ABS module by pressing the release tab and pulling it out.
Remove any mounting bolts securing the ABS module using a socket set (typically 10mm or 12mm).
Carefully lift the ABS module out of its mounting location.

3. Inspect and Replace

Inspect the ABS module for any visible damage; if damaged, proceed to replace it.
If the module is faulty, install a new ABS module by reversing the removal steps.
Torque the mounting bolts to the manufacturer's specifications (refer to service manual for exact torque values).
Reconnect the wiring harness securely to the ABS module.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check for any warning lights on the dashboard.
Perform a brake system test to ensure ABS functionality.
