Detroit® Connect Virtual Technician® Available on Detroit DD5™ and DD8™ engines

Virtual Technician helps fleet’s make informed service decisions within minutes of an engine or aftertreatment fault event by notifying fleet managers that a fault code has been triggered, and by diagnosing the root cause of the code, recommending a solution and helping source the parts needed for repair.
The magic? Virtual Technician records critical vehicle performance data immediately—before, during and after—a fault occurs, giving Detroit engineers the most relevant information to interpret fault codes—and provide expert recommendations. Discover engine issues quickly, avoid costly downtime and locate nearby service when critical repairs are needed.
Activate Virtual Technician, which comes standard on Detroit during the engine warranty period.
Cummins Connected Diagnostics™ Available on Cummins Engines

The unique analytics data sent by Cummins Connected Diagnostics is more valuable than a simple lamp on the dash and more complete than raw data pulled from the electronic engine system.
It identifies and prioritizes the fault codes, determines the probable cause of the fault, reports this information to fleet management through preferred communication method: email, mobile app or online portal. And with Cummins Connected Advisor™, receive expert, in-depth analysis, recommendations and reporting from Cummins diagnostics technicians—straight to your email inbox. Facilitate repairs, minimize costly downtime and protect your vehicle’s overall health.
