Tips & Guides Heavy duty truck diagnostic tool – Which BEST

Here are views of popular Heavy Duty Truck diagnostic Scanner or adapters, including pros & cons and tips & tricks.

DG Tech DPA4 or 4+ or DPA5: #2 Choice Metal case makes it durable (must use original USB cable to take advantage of USB port protection)

DPA5 is better than the DPA4+ in that it supports OBD2 Scanner protocols other than J1850VPW and CAN, it also has the long range bluetooth and comes with a bluetooth dongle for your PC.  It has a metal case, rubber shock caps, secure USB and long diagnostic cables unlike the 6″ Nexiq cables.  It is dual CAN, has a large buffer and works well with any application.

NEXIQ USB Link: #1 Choice can also be used with toyota techstream and isuzu IDSS (Must be very careful to not break the usb port on older style)

Having ever used the Nexiq USB Link or Nexiq USB Link 2, I can’t say I really prefer it so much as until fairly recently I didn’t even know there was so many other options as those two are almost the entirety of what I ever see.  Only after recently purchasing a Nexiq USB Link 2 did I begin to realize that so much else (aside from OEM ‘boxes’) was even available.

So far I’m still pleased with the Link 2, but had I done a bit more digging prior to buying it I certainly would have compared it to the DPA5 and might have gone that route just given what I’ve found out about them so far.

About the only complaints I have with the Link 2 so far are the increased price of the adapter cables vs the original (or even other current models) and that connecting via Bluetooth is quite the chore for some reason compared to other (in general) devices.  Given how long the USB cable is though, I’m not terribly concerned with the Bluetooth connectivity.

Nexiq Magikey: Was the best back in the day (Need a PC with printer port to connect)

Nexiq LiteLink: Works with Snapon Modis (older J1708 Data Bus only)

Cummins Inline: RP1210a compliant for apps other than Cummins Insite (Doesnt work well with all rp1210a applications)

Movimento/Navlink: Only way to connect to TCU via IDS on Ford/Int LCF/CF Trucks??? (Freezes using servicemax on some laptops)

Navistar IC4: Small durable adapter (Bad customer support, hard to find drivers, USB cable is part of adapter)

Older PF-Diagnose adapter (B&B Electronics): Small durable adapter (serial cable connection)

Eaton Wireless: Long wireless range (intermittent data loss even at close range)

Noregon DLA: #3 Choice alternative to Nexiq and Dearborn (Large size/odd shape)

Cat ET: Only way to connect to some offroad equipment with CDL data Bus (Need PC with printer port)

This is just my opinion on the adapters above based on personal use.  There are other adapters available and other peoples results/opinions may differ.

Which Tool is Best for Truck Diagnostic & Programming

Have search info for a few days ago because I want to learn about how to set myself up with Truck Diagnostic Tool/programming software and the proper tools to do my own work.

Topic: Looking for a good truck performance programmer

Purpose:
I want to be able to read codes on our trucks, address check engine lights, abd lights and whatever else.

Changing parameters would also be nice to do.

Truck:

We have 5 trucks. 3 of mine all have series 60. From ddec 2 up to ddec 4. He has an isx and an Acert. Our trucks are kenworth, Peterbilt and a intl 9200. Would also like cab side on those.

Budget:

I think a $4-500 one should fit the bill.

(Am I able to find everything I need rather than paying some company $4-5k for a tough book and some programming?)

Diagnostic tools looking for trucks:

I have seen a nexiq also the new NEXIQ USB Link 2 and a drewlinq. I think they all serve the same purpose?

Recommendation for hookup: (credits to Samsquantch84)

Laptop: You can pick up a used Lenovo T410 on the web for like $200. They are durable laptops not the best battery life. but get one that has an i5 processor. They are more than fast enough. If you get a laptop that is a little under powered it makes the programs run slow which is really annoying for doing diagnostics. They are pretty rugged laptops.

Equipment: Definitely the best solution is to buy an authentic Nexiq usb link one or two. But if within your budget, a good Nexiq clone of high quality (now called VXTRUCK) should be OK. It’s $200 around. I have to tell you, you need have luck with Chine clone coz you may have nothing but issues with the clone. Go to a good man of his word to trust.

The only real difference between the old one and the new one is the two is that the usb link two supports newer vehicles like ghg17. You probably won’t need it.

Also be careful buying one online unless it is a reputable source. There are some really good looking clones available that are deceiving. obd2tool.com is a supplier of the HQ NEXIQ USB Link and has great support so that is the only source I recommend. I have used it to program a new chip. Success.

Software: As far as software goes. Find Detroit DDDL, Cat ET 2017, Cummins insite 8.1 and you should be good to go. All are easy to get for free from forums or other place.  Also, have a try with crack versions tested by professionals. If you start getting into new Pete’s or kenworth’s like 2012’s(my date’s might be alittle off) and up paccar esa might be handy as well. It connects to the body controller side and allows you to control things like if you install led headlights in a truck that had incandescent you have to change a setting in the cecu for it to work. Also keep learning. There is so much help and information available on this forum from some of the right people. you will learn who they are. Congrats on trying to better your self. and if you have any questions just ask. International uses diamond logic build for the cab side. It’s not the most user friendly software, just like their trucks, who in their right minds uses straight thread o-ring to push to connect air fittings…errrrrr. Also you can go on

quickserve.cummins.com and register for a free limited owners plan which gives you access to parts and service manuals for up to 5 engine serial numbers for free. and dependent on your peterbilt and kenworth dealers you can register with them your vin numbers to a fleet e-cat. It gives you access to look up your vin numbers and view wiring diagrams. It can come in handy.
