Detroit Connect Virtual Technician

Detroit Connect^®, a suite of proprietary connected vehicle solutions, is designed to improve your bottom line. Detroit Connect provides fleets and owner-operators services and tools to improve uptime, fuel efficiency, safety, and performance. These tools provide you information about your vehicle you can’t get anywhere else to better manage your business operations.

The Detroit Connect Virtual Technician^® remote diagnostic service takes the guesswork out of engine repair. When a truck’s check engine light illuminates, data is collected immediately, providing a technical snapshot of the engine’s status before, during, and after a fault code event.

This information is sent to you and to the Detroit Customer Support Center (CSC), where a trained representative can diagnose the issue, recommend service and even contact the nearest authorized Detroit dealer with parts in stock. The CSC can tell you if you need to pull over so you don’t cause further damage, or if you can stay on the road.
