Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during repair.

2. Remove the ABS Module

Tools Required: Socket set, torque wrench, brake line wrench
Locate the ABS module, typically found near the master cylinder.
Using a brake line wrench, carefully disconnect the brake lines from the ABS module, and use a catch pan to collect any brake fluid.
Unplug the electrical connectors from the ABS module by pressing the release tabs and pulling them out.
Remove the mounting bolts securing the ABS module to the vehicle and carefully lift it out.

3. Inspect and Clean

Check the old ABS module for any visible signs of damage (cracks, corrosion).
Clean the mounting surface on the vehicle to ensure a proper seal for the new module.

4. Install New ABS Module

Position the new ABS module in place and secure it with mounting bolts.
Torque the mounting bolts to the manufacturer’s specifications (usually around 15-20 ft-lbs).
Reconnect the electrical connectors firmly until they click into place.
Reconnect the brake lines using a brake line wrench and ensure they are tight to prevent leaks.

5. Bleed the Brake System

Tools Required: Brake bleeder kit, brake fluid (OEM specification)
Fill the master cylinder reservoir with fresh brake fluid.
Bleed the brakes at each wheel to remove air from the system, starting with the wheel farthest from the master cylinder.
Check and top off the brake fluid level as necessary.

6. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and verify that the ABS warning light is no longer illuminated.
Conduct a test drive to ensure proper ABS functionality.
