How to Upgrade your Automotive Engine in Maryland

In Maryland, you can upgrade your engines in the following ways: The Maryland Vehicle Inspections and Quality Assurance Office (VQAO) has been using the Automotive Data Network (ADN) for a decade to identify the defects found in the engine.

The ADN allows the VQAo to track engine failures, inspect them, and inspect the parts that cause them.

If you’re an authorized service technician and are using the ADN, you’ll need to install an update package.

The following instructions walk you through the installation and use of the update package that’s included with the ADP, along with instructions on how to perform a service manual and how to use a software tool to perform the upgrade.
