5. The unique information sent by Connected Diagnostics™ is much more valuable than the lamp on the dash, and more complete than raw data pulled from the electronic engine system.

6. Connected Diagnostics™ enables proper care for the engine system while maximizing uptime without the time previously needed to investigate the cause of the check engine lamp.

7. The moment an engine system fault occurs, the telematics system instantly transmits key engine system and GPS data through the telematics connection currently installed on your Cummins-powered equipment.

8. And, only Connected Diagnostics™ can report engine performance derate timers that may have been triggered by the fault.

9. Connected Diagnostics™ applies unique Cummins analytics to transform the data into actionable information.

10. Suggesting probable root cause of the fault to the component level, Connected Diagnostics™ facilitates the repair and minimizes downtime.

11. An active connection to a compatible telematics provider is required for data transmitted from the equipment’s SAE J1939 data link and an active cellular or Wi-Fi connection is required for the mobile device to receive equipment status updates.
