User reviews

We can’t use this device

Every time said Password device we just lost 350$ bought this device

Last version terrible

The latest version of the software is not usable for working with PACCAR.
Before this update, I was always satisfied with it and never had any issues. Now it has become extremely difficult to use.

Fault codes are much harder to read and understand than before.
Previously, there were never any problems starting a regen or clearing a derate. Now it is almost impossible to do.

My assessment: the only reasonable option is to unsubscribe and throw the device away.

No regen

Assuming most of the people want to be able to do regen, don't bother with this. Not working even with subscription, at least for Volvo trucks

Waste of money

In a true repair shop environment this tool is useless. Once they charge 30.00 a month for Regen access this thing is a paperweight for my to do list. That’s right 350.00 for a paperweight. Find something that works as described with no subscription

Not Performing or Scanning Solution

Product Amazing Customer Support Horrible
