OTR Diagnostics is your new go-to diagnostic tool for repairs. You can use OTR Diagnostics to connect, read fault codes, and perform advanced commands such as resetting fault codes, resetting aftertreatment systemsand performing forced DPF regens on most engine makes and models. OTR is committed to adding new functionality to the app that empowers you to perform advanced diagnostics faster and easier than ever before. 

What is the purpose of a mobile diagnostic app if I have dealer-level software?


Great question! We love dealer level diagnostic software. However, some dealer level software requires internet access at all times, while other dealer level software requires constant updates that never seen to happen when you have the time. Not to mention the equipment is expensive and you have to have extensive knowledge of the program to perform the diagnostics that you are looking for. 

Moreover, there isn’t a one size fits all solution in the diagnostic marketplace so if you have multiple trucks with different engines you need numerous diagnostic software at your disposal to perform diagnostics.  

What hardware do you need for OTR Diagnostics? 

OTR link

You need a Bluetooth adapter called the OTR Link to be able to use OTR Diagnostics. In order to provide the most powerful and secure wireless connection to your vehicle, we partnered with Nexiq Technologies to provide the hardware. The hardware for OTR Diagnostics is called OTR Link powered by Nexiq 

Other than the OTR Link all you need is a mobile device like your phone.  

How do I get started with OTR Diagnostics?  

We recommend using the diagnostics that bundle the hardware + subscription when you proceed to purchase.
