INLINE 6 End of Support Update
End of Support for INLINE 6 Datalink Adapter
Effective April 2026, Cummins will end support for the INLINE 6 and all earlier datalink adapters (INLINE 4, 5, etc.) across its diagnostic software platforms. The upcoming INSITE 10 release will no longer recognize or communicate with these legacy adapters, rendering them non-functional for diagnostics, troubleshooting, or ECM connectivity. A parallel change is expected for Guidanz Diagnostic Toolkit (DTK) v3.7, planned for July 2026. The final cutoff for any legacy adapter usage via the older INSITE 9.3 application is March 2027.
Key Timeline of Milestones
- April 2026 - INSITE 10 Release
- INSITE 10 maunches as a dedicated 64-bit application. From this date forward, INLINE 6 and all older adapters will not work with INSITE for any diagnostic function.
- July 2026 - Guidanz DTK 3.7 Release (Planned)
- Guidanz Diagnostic Toolkit v3.7 is expected to drop support for INLINE 6 and legacy adapters. A separate communication with firm dates will be issued.
- March 2027 - End of INSITE 9.3 Support
- Official end of support for INSITE 9.3. After this date, no Cummins-supported diagnostic software will function with INLINE 6 adapters.
Why This Change Is Happening
INSITE is being modernized to a dedicated 64-bit architecture in version 10, moving away from its prior dual 32-bit/64-bit environment. This transition delivers measurable customer benefits:
- Improved overall tool performance and speed
- Significant reduction in application crashes (resolving memory buffer limitations)
- Better alignment with modern computing hardware and software standards
INLINE 6 and older adapters cannot operate in this new environment. Although INLINE 6 possesses 64-bit OS drivers, those drivers are not designed to interface with 64-bit applications — they lack the true 64-bit application-level drivers required by INSITE 10. The INLINE 6 hardware has been formally obsolete for several years.
