Navistar Diagnostic Tools

Click here to download the Navistar Diagnostic Tools pdf.

Items that are required to diagnose IH electronic engines and multiplexed dashboards:

1.   Engine Diagnostic Software (ServiceMaxx, Service Assistant, (Saint) or
      Master Diagnostics (MD Fleet)
2.   Multiplexed Dashboard diagnostic software (Diamond Logic Builder or Intune)
3.   ISIS (service manuals on disc, now called On Command)
4.   Communications cable to connect your laptop to the truck (Nexiq USB Link or similar)
5.   EGED and EGES Diagnostic forms for your engine (there are 75 total for all engines)
6.   Optional: ABS, Allison, and Instrument panel software, see below

ISIS- (IH Service Manuals, now called On Command) on DVD available from your IH dealer parts dept. at a cost of about $300. It is their complete service manual covering engine repair, chassis service, and diagnostics on all engines back to the 1980’s. It also includes electrical schematics from 1998 up. Schematics for pre-98 trucks are available on paper only.

If you are a fleet, you should subscribe to OnCommand (ISIS) online, which gives you not only service information but current TSI letters and most important, IKnow letters. IKnow letters may be some of the most important information when repairing later trucks as they are letters regarding pattern failures and part updates.

Critically important!

IH releases an emissions compliance with the following model year, such as a 2004 emissions engine is not found in a 2004 VIN truck but rather a 2005 VIN truck.

•   For trucks with Vins through 2004, use the 2003 service manual (DT466E non EGR engine)
•   For trucks with Vins 2005-2007, use the 2004 service manual (DT466 and DT570 engines with EGR)
•   For trucks with Vins 2008-2010 use the 2007 service manual (MaxxForce 9, 10, DT engines)
•   For trucks with Vins 2011 up, use the 2010 service manual (MaxxForce 9, 10, DT engines)

You can easily identify your engine by the engine serial number plate on the valve cover:

•   DTE (’95-’04 VIN) ESN- 1,000,000
•   DTEGR (’05-’07VIN) ESN- 2,000,000
•   MaxxForce DT, 9, 10 (2008-2010VIN) ESN- 3,000,000
•   2010 Emissions MF DT-3,300,000 (2011+ VIN)

Diagnostic Equipment:

  • Nexiq www.nexiq.com is now the supplier and all software is distributed through various warehouses such as Chalk’s Truck Parts (800-231-5061) or your local IH dealer.
Engine Diagnostic Software: (note you will also need a communications cable, see below)
  • ServiceMaxxis the current software for engine diagnostics. PN 828009D9 $650 list plus $300.00 per year subscription fee. All of these softwares do a great job at the factory level for diagnostics. They access data and diagnostics on all IH electronic engines- 1994 to current T444E, VT365, DT466E, 530E, DT466 (EGR), DT570, HT570, VT275, and all MaxxForce engines. This software does not work with Cat, Cummins, or Detroit engines. ServiceMaxx has somewhat of a steep learning curve, casual users be forewarned, and has a lot of glitches in it. Turbo Training does offer a ServiceMaxx book available to help you learn the program. I suggest the Nexiq USB Link comm cable for this program.

  • Master Diagnostics AKA MD32 or MD Fleet (discontinued) will access late engine pids (2008 up with DPF) but will not access DPF pids used for diagnosing aftertreatment systems. Master Diagnostics (MD Fleet), and Service Assistant (SAINT) are excellent OE softwares, but may not access the exhaust aftertreatment PIDS on 2008 up trucks.

  • Service Assistant for IH Trucks AKA Saint (discontinued) was a revised version of MD. It will access late engine pids (2008 up with DPF) and aftertreatment systems but may not give full diagnostics on 2008 up MaxxForce engines.

Dashboard/Chassis Diagnostic Software: (note you will also need a communications cable, see below)

  • Diamond Logic Builder PN 828005 $775, Multiplexed dashboard diagnostic software for later IH trucks from 2001 up: models 3200, 4100, 4200, 4300, 4400, 7400, 7500, 7600, 7700, 8500, 8600, etc. Intune was the old multiplexed software, which was replaced several years ago with Diamond Logic Builder, which is the new multiplexed software. Instrument Panel Cluster (IPC) is good for 4700/4900 series from '97-02. The multiplexed trucks after that use DLB (or INTUNE, if you happen to have an old copy). This program also has a steep learning curve. Turbo Training has about 100 pages of information on learning it in the IH Multiplexing book.

  • IPC- Instrument Panel Cluster Diagnostic Software PN 850042 $350 for ’97-01 MD and HD data-driven dash (these trucks read dash info from the J1708 data stream but are not fully multiplexed dashboards) This includes all ’97-2002 4700, 4800, and 4900 models.

  • Allison Doc for Allison Transmissions: $695, works all most comm cables (except for late Gen4 reflashing) diagnosticinnovations.com Software PN is J44950-G and is compatible with most comm cables for diagnostics. If you need to do reflashing of Allison controllers, you will need the Dearborn DPA4USB cable kit for flashing the later Gen 5 Allison controllers used from about 2006 on up. http://diagnosticinnovations.com

  • Hydraulic ABS diagnostic software PN 850044 $325 for 1998-2002 4700 series trucks.

  • Hydraulic ABS diagnostic software for NGV (2002 up 4200/4400 trucks) Use Wabco Toolbox software, call 800-328-6657 to order.

  • Bendix Air ABS: Download the free program from http://www.bendix.com/en/servicessupport/abssoftware/absdiagnostic.jsp or Bendix.com. You will also need any of the comm cables.


Communications Cables:
You will need at least one, and it depends on what you’re working on to determine which cable(s) you’ll need. The cable with the least communications issues is the Nexiq USB Link. The only oddball applications are reflashing late Allison computers, and late Cummins service, which are both cable-specific programs.

Generic type RP1210 compliant cables which work with most software:

  • Nexiq USB Link ( PN 125032 USB-Link, www.nexiq.com) Works well and is the preferred choice for most fleets. It is also available in wireless.

  • Movimento NAV-Link/NAVCoM: The factory supported cable is the Movimento NAV-Link for most fleets and NAVCoM for dealers. Purchase it through your IH dealer.

  • EZ Tap Wireless: Wireless: Wireless RP1210 cable for all HD diagnostic software on most J1708/J1939 platforms. http://www.xscapeez.com/products.html

  • IC4COM Cable kit Part Number ZTSE4632-USB Even though IH is no longer supporting this cable, it is likely to work on most software just fine except ServiceMaxx, especially on older engines. http://international.spx.com or http://www.suenterprise.com/Default.asp, $400-700

  • Eaton MD 100 Part Number: VL-Kit-01 $565 www.diagnosticinnovations.com

  • Auto Tap for Trucks- software that talks in generic J1708 to most engine/trans/ABS systems, gives codes and limited data stream. $599 and includes the MD100 cable above. This is a good choice for independent garages that work on all makes because it gives you a basic software package and a comm cable that can be used for most IH applications except 98-02 hydraulic ABS. www.autotap.com

I'll forewarn you of what's coming in the future: As software becomes more complex, each software will require its own comm cable due to ever changing communications protocols. This has already happened with Allison Gen5 and Cummins, and is likely to become more widespread. Enjoy the time being where one cable does nearly everything, because that time will end in the future. will end in the future.

Other diagnostic tools you may need:
  • Breakout box for 2005 up DT466/570 EGR engines: 96 pin DLC2 systems, ZTSE 4582A $1343
  • Breakout box for 2008 up MaxxForce 9, 10, DT, $3000 available from your dealer.

  • ZTSE 4725 HP oil “puck” tool (needed, but not required)

Navistar Engine Diagnostic Forms

These forms are full color schematics and diagnostic charts, very helpful when performing diagnostics. They are included in ISIS, but not readable or printable. They are large full color 8 ½” x 17” and come in pads of 40 from your dealer for about $15/pad. Some have been discontinued from IH, e-mail me for a PDF of these.

TSI Number:

TSI Date:
April, 2004

Subject File
: Engine

Warning! Diagnostics sheets are labeled with the emissions year application, not the model year (by VIN) application of the truck. (See note above regarding service info vs model year)

For example, the EGED sheet labeled “model year 2007” is not for model year 2007, it is for model year 2008 (by VIN). This is very confusing for a novice!
