Cummins Guidanz™

Guidanz is a suite of genuine service products, features and capabilities that maximize efficiency by streamlining processes associated with any service event. Many commonly known service systems (QuickServe, RAPIDSERVE™ Web, INSITE™, etc.) are now integrated into a single sign-on interface, thus streamlining the service workflow. Products in the Guidanz suite include: Guidanz Web, Guidanz Mobile App, Immediate Assessment and the INLINE™ mini vehicle adapter.

Guidanz Mobile App

The mobile app quickly identifies key engine data and J1939 fault code information that can be shared with service providers to help expedite the repair process. Data is pulled from the engine using the INLINE™ vehicle adapter that wirelessly connects to the mobile app via  Bluetooth®/ cellular data connection.

Immediate Assessment

The Immediate Assessment (IA) feature on the Guidanz™ mobile app is a valuable feature for Certified Service Providers, dealers and fleets that assist in reducing assessment/triage time from several hours to a few minutes. IA facilitates scheduling service jobs, technician assignments and better use of service bay and personnel.

Immediate Assessment features include:

  • Repair time estimates
  • Most likely repair parts
  • Easy work order creation
  • Seamless transition to Guidanz Web

Guidanz Web

Guidanz Web offers a common interface to Cummins service systems, allowing certified service providers the ability to quickly answer customer service needs. The system removes duplicated data entry and the need to have multiple websites and software running at the same time. Information is easily accessible through comprehensive service history and convenient service links (fault codes, manuals, previous warranty claims, etc.).

Features include:

  • One page summary provides up-to-date status of the service event to give to the customer
  • Warranty claims creation and processing
  • Automatic job creation from the Immediate Assessment feature on the Guidanz mobile app
  • Integrated diagnostics and repair experience
