Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shock.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Remove the Old ABS Module

Locate the ABS module, typically found near the brake master cylinder.
Disconnect the electrical connectors from the ABS module by pressing the release tab and pulling them out.
Remove any mounting bolts using a socket set (usually 10mm or 13mm).
Gently pull the ABS module out of its mounting bracket.

3. Install the New ABS Module

Position the new ABS module in the mounting bracket.
Secure it using the original bolts, tightening them to the manufacturer’s specified torque (usually around 10-15 ft-lbs).
Reconnect the electrical connectors, ensuring they click into place securely.

4. Bleed the ABS System

Reconnect the battery.
Use a scan tool to activate the ABS pump and bleed the system, if applicable.
If no scan tool is available, manually bleed the brakes starting from the farthest wheel from the master cylinder (usually the passenger rear) and moving to the closest (driver front).
