Collection: International & Navistar Diagnostic Software

Diagnostic software for International trucks and Navistar-built engines. Whether your unit runs a Navistar in-house engine or a Cummins drop-in, this collection has the tool that actually talks to it.

Engines and trucks covered

  • MaxxForce DT, 7, 9, 10, 11, 13 and 15
  • International A26 (12.4L)
  • Cummins-powered Internationals (ISX15/X15, ISB/B6.7) — handled with the matching Cummins tool
  • Trucks: LT, LoneStar, ProStar, HX, MV, DuraStar, WorkStar and older 4000/8000 series

What the software does

Read and clear fault codes with freeze-frame data, run bi-directional tests (aftertreatment/DPF regen, cylinder cut-out), view live parameters, and change customer parameters like road speed and idle shutdown on supported trucks. Aftertreatment and EGR faults — the most common reason a MaxxForce derates — are front and center.

Adapter

An RP1210 interface (Nexiq USB-Link 2/3 or equivalent) connects your laptop to the 9-pin or 16-pin diagnostic port.

Tell us your engine and model year and we'll match you to the exact version, then install and activate it remotely the same day.
