Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.

2. Remove the ABS Module

Locate the ABS module, which is usually mounted near the master cylinder.
Disconnect the electrical connectors carefully without damaging the terminals.
Remove the mounting bolts (typically 10mm) securing the ABS module to the bracket using a socket set.
Gently lift the ABS module from its mounting position.

3. Inspect and Clean

Inspect the ABS module for visible signs of damage or corrosion.
Clean any dirt or debris from the module mounting surface and connectors.
If necessary, clean the electrical connectors with electrical contact cleaner.

4. Replace the ABS Module (if faulty)

Install the new ABS module by aligning it with the mounting bracket.
Secure the module with the mounting bolts, tightening them to the manufacturer’s specifications (typically 7-10 ft-lbs).
Reconnect the electrical connectors ensuring they click into place.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS warning light is still illuminated.
Perform a test drive to verify the proper operation of the ABS system.
