Step 2: Disconnect the electrical connectors from the ABS module by pressing the tabs and pulling them apart.
Step 3: Unbolt the ABS module from its mounting bracket using a socket set (torque specifications may vary; refer to service manual).

3. Inspect and Replace

Step 1: Visually inspect the ABS module for damage or corrosion.
Step 2: If necessary, replace with a new ABS module; ensure the replacement is compatible with the 2016-2022 Honda Pilot YF3.
Step 3: Reinstall the ABS module by reversing the removal steps and torque bolts to the manufacturer's specifications.

4. Reconnect Electrical Connectors

Step 1: Reconnect all electrical connectors securely to the ABS module.
Step 2: Make sure all connections are tight to prevent future issues.

5. Reconnect Battery

Reconnect the negative terminal of the battery and ensure it is secure.

6. Bleed the Brake System

Step 1: Using a brake bleeder kit, bleed the brake system to remove any air trapped in the lines.
Step 2: Monitor brake fluid levels and top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
