The Navistar Pack sold on this page is a diagnostic and programming software package for International and Navistar equipment — not engines, complete trucks, or replacement parts. It bundles the software a technician needs to connect a laptop to a truck, read fault codes, run tests, and program parameters on International and IC Bus vehicles. We install it remotely on your Windows laptop over TeamViewer, so you can be diagnosing a truck the same day.
What Is in the Navistar Diagnostic Software Pack?
A complete Navistar Pack is built around three programs, each covering a different part of the truck.
Navistar Engine Diagnostics (NED)
NED is the engine-side tool for 2007 and newer International and Navistar electronic engines. It reads and clears engine fault codes, runs actuator and special tests, displays live engine data, and lets you change or program engine parameters within what the ECM allows.
ServiceMaxx (J1708 and J1939)
ServiceMaxx is the other engine diagnostic environment. The J1939 build handles 2007-and-newer electronic engines, while the J1708 build is what you need for 2006-and-older engines that use the older datalink. Between the two, you can cover most electronic International and Navistar engines still on the road.
Diamond Logic Builder (DLB)
DLB is the body and chassis tool. It reads and programs the Diamond Logic electrical system on International trucks and IC Bus vehicles — lighting, interlocks, body controllers, and switch logic. This distinction matters: DLB works on body and chassis electrical, not the engine ECM, and NED does not program body electrical. That is why a real pack includes both tools rather than one.
Coverage by Model Year and System
| Software | Covers | Role |
|---|---|---|
| NED | 2007 & newer International/Navistar electronic engines | Engine diagnostics and parameter programming |
| ServiceMaxx J1939 | 2007 & newer electronic engines | Engine diagnostics |
| ServiceMaxx J1708 | 2006 & older engines | Engine diagnostics on the older datalink |
| Diamond Logic Builder | Diamond Logic body/chassis electrical on International trucks and IC Bus | Body/chassis programming, not engine |
Engine Platforms the Software Covers
On the engine side, the software supports Navistar’s electronic engine families — it does not ship any hardware. The A26 is the current flagship: a 12.4L inline-six rated up to 475 hp and 1,750 lb-ft, running a 2,500 bar (36,300 psi) high-pressure common-rail fuel system and a variable-geometry turbo with a titanium compressor wheel. Introduced in 2017, it is built on the MAN D26 crankcase. The older N13 is a legacy platform the software still supports, so a shop running a mixed-age fleet can service both families from the same laptop.
What You Need to Connect the Laptop
The software talks to the truck through an RP1210 datalink adapter, which is not included in the pack. Most technicians use a NEXIQ USB-Link 2 or USB-Link 3, or a DPA5. You supply the adapter and cables; the pack supplies the software that drives them.
What the Software Actually Does in the Bay
- Read and clear diagnostic trouble codes (DTCs)
- Run actuator, output, and special or self tests
- View and graph live engine data
- Change and program engine parameters where the ECM permits
- Read and program Diamond Logic body and chassis electrical with DLB
When a code points at an EGR fault, a sensor, or a turbo actuator, the software identifies what failed so you can source and replace the part elsewhere. It diagnoses components; it does not supply them.
OnCommand Connection Is Separate
OnCommand Connection is Navistar’s own factory telematics and remote-diagnostics service, sold by the manufacturer on its own subscription. It is not part of this software pack. What you get here is bay and laptop diagnostics: you connect directly to the truck to read codes, run tests, and program parameters — not fleet telematics.
Who This Pack Is For
This software fits independent diesel repair shops, mobile diesel technicians, and small fleets that service International and Navistar trucks and IC Bus vehicles in-house rather than sending every job to a dealer. If your work involves reading Navistar engine codes or programming Diamond Logic electrical, this is the toolset for it. You can also browse related titles in the diagnostic software shop.
Remote Installation and Support
We deliver the pack by remote TeamViewer installation — no shipping and no wrestling with drivers on your own. The download is roughly 300 MB and installs to about 1 GB, runs on Windows 10 and 11, and comes with a 2-year license. A technician sets it up on your laptop, confirms it launches and connects, and stays available to help with activation and after-sale questions. Order the Navistar Pack and book your TeamViewer install session, and you can be reading codes on an International truck the same day.
