Fault Code Diagnosis

Quickly pull up active and stored fault codes from any electronic control module. See exactly what's triggering that warning light on the dash, then clear codes after you've made repairs.

Live Data Monitoring

Watch sensor readings in real-time while the engine runs or systems operate. Track down intermittent problems by monitoring data while you drive or operate the machine.

System Testing

Run actuator tests, force component activation, and verify that sensors and switches respond correctly. Great for pinpointing exactly where a problem lives in the system.

Parameter Programming

View and modify ECU configuration settings. Adjust operational parameters, set up new attachments, or configure features for specific applications.

Frequently Asked Questions

Does this include diagnostic software?

No, this is the hardware adapter only. You'll need compatible diagnostic software to communicate with your equipment. This gives you flexibility to choose the software that best fits your needs.

What computer do I need?

Any Windows 10 laptop or PC works. We recommend at least 8GB of RAM and 100GB of free storage space for smooth operation.

How do I connect to my equipment?

Most modern agriculture and construction equipment has a 9-pin Deutsch diagnostic port, usually located in the cab or engine compartment. Connect the adapter to that port, then plug the USB cable into your computer.

Will this work on older equipment?

This adapter works best on equipment with CAN bus electronic systems, typically machines built from the mid-2000s onward. Older machines without electronic controls may not be compatible.

Can I use this for ECU programming?

Yes, with compatible software you can perform ECU programming, parameter changes, and system calibrations. Specific functions depend on the software you're using.
