Connected Diagnostics™ is your lifeline to Cummins when you need it most. Using telematics, your Cummins-powered equipment wirelessly connects your engine to Cummins for immediate diagnosis of an engine system fault alert, and provides valuable information you need – within seconds.

Broad compatibility with leading telematics providers allows Connected Diagnostics™ to serve a wide range of global markets that depend on Cummins electronic engines, in both on-highway and off-highway applications for many makes and models of equipment.

How Connected Diagnostics™ Works
The moment an engine system fault occurs, the telematics system instantly transmits key engine system and GPS data through the telematics connection. Connected Diagnostics™ immediately applies unique Cummins analytics to transform the data into actionable information. A diagnosis of the fault, and clear recommendations regarding continued vehicle operation or the need for immediate service, are sent instantly to you. Connected Diagnostics™ is a critical lifeline that enables you to properly care for the engine system while maximizing your uptime and equipment availability without the downtime previously needed to investigate the cause of the fault.


Connected Diagnostics


Expert Guidance
Connected Diagnostics™ uses the power of Cummins to analyze the fault code data, prioritizing all active and recently inactive faults to provide a high level of confidence that the recommendation to stop immediately or service immediately is the right one. Determining the root cause of the system failure to the component level, Connected Diagnostics™ facilitates the repair and minimizes downtime.

Effective Information
The unique information sent by Connected Diagnostics™ is much more valuable than a simple lamp on the dash, and more complete than raw data pulled from the electronic engine system. Connected Diagnostics™ identifies and prioritizes the fault codes, determines the probable cause of the fault and reports it to you.

Only Connected Diagnostics™ can report engine performance derate timers that may have been triggered by the fault. You can then take action, knowing the time and impact of a pending derate, to help avoid progressive engine damage, ensuring the health of your engine and aftertreatment system and reducing expensive equipment recovery charges.

Instant Value
Connected Diagnostics™ immediately provides you with the information needed to make informed, time-critical decisions within seconds of a fault occurrence, enabling you to avoid unnecessary expenses and lowering the potential for progressive engine system damage.

Connected Support
Connected Diagnostics™ automatically identifies the nearest Cummins-certified repair location with Genuine Cummins parts and factory-certified technicians trained to repair your equipment. During this process, a Cummins Care work order is created, so when you call Cummins Care at 1-800-CUMMINS™ (1-800-286-6467), the representative will be able to immediately access details about the fault event for efficiency and accuracy. This same level of detailed information can also be made available to certified Cummins repair locations.
