Diagnostic tool for Cummins ISX15

[APC]

in order to do basic diagnostics, you can use a laptop with Cummins INSITE to read fault codes, view live data, monitor things, etc....

you will also need a pass through interface such as a Nexiq USB Link 2/3 device, or a Cummins Inline adapter... I recommend you buy only OEM, as the Chinese versions can have some issues...

as far as reading and writing the program in the ecm, you will need to use c a l t e r m to read the program and write the program out of the ecu. along with c a l t e r m you will need a proper E C F G file (configuration file) for the specific engine, and ECM calibration version in order to properly edit the data and send it back to the ECM...

a good "all around" software that will scan your detroits, volvos, and cummins engines is Jpro ... keep in mind that universal softwares that work for multiple engines, will always have some limitations compared to the OEM software... my best reccomendation is that you find the 3-4 most popular trucks/engines you work on and source the software you will need for each one.

Nexiq USB Link adapter (oem only, not chineesium) is the most versatile for multiple brands of engines.
