What is PF-Diagnose?

As a brief refresher to those that are not aware, PF-Diagnose is an aftermarket PC based software diagnostic program that works for Heavy Duty Truck, Medium Duty Truck, Light Duty Truck, Automotive, Agricultural, Industrial, and Marine. This simple to use, yet very powerful, diesel diagnostic program will allow you to read engine codes (and get actual OEM flash codes!), view live engine data, clear codes, record snapshots, and much more. You can read more about it on the Pocketfleet website, or on our website as well.

PF-Diagnose and Engine Parameters

As you can, see that is quite a list! There is actually even more listed in the Specialized tabs (Emissions, Readiness, Trip, Fuel, etc…). However, PF-Diagnose does not read audit trails or logged parameters like such programs as Detroit DDEC reports. We’ve also included screen shots of these tabs so you can see what they look like:

PF-Diagnose Readiness Tab
PF-Diagnose Trip Tab
