Diagnostics Like Never Before
OTR Diagnostics, the most powerful advanced mobile diagnostics app available for iOS. Those days of lugging around big equipment to perform advanced diagnostics are over. You don’t need complicated software or multiple programs – all you need is your vehicle, a phone, and an adapter.
OTR Diagnostics gives you the power to run advanced diagnostic functions, including a forced DPF regen from your mobile device.
OTR Diagnostics is an advanced automated diagnostic app that makes it quick and easy to understand what’s taken your truck off the road.
You’ll have the power to clear fault codes, reset the aftertreatment system by reprogramming all the parameters to default values, and if necessary, perform a forced DPF regen of the DPF. Anywhere, anytime.
Who’s OTR Diagnostics for?
OTR Diagnostics is for fleet owners, owner-operators, drivers, and technicians who are tired of paying every month for check engine lights, regens, and resets.
With OTR Diagnostics, you’ll instantly be able to:
- Cut down on the days your vehicles spend in repair shops
- Get a deeper insight into your engine’s performance and each rig’s unique quirks
- Drive confidently at night or out of state with less worrying about getting stuck
If you’ve ever lost a day (or a load) due to breakdowns, engine faults, soot level, or mysterious, un-re-creatable ghost codes, you need OTR Diagnostics.

APP FEATURES
*Available with Plus and Pro Subscription.
Enhanced Fault Code Descriptions
Read Fault Codes. You’ll be provided with enhanced detail fault code information.
For instance, you’ll see the following displayed:
- SPN 27 FMI 3
EGR valve position sensor circuit
Engine Controller
Detailed fault code information, will be provided such as description, troubleshooting, symptoms, and possible fixes.
Fault Code Commands
Reset Active Fault Codes. Fault codes that determine that there is an existing issue. Certain active fault codes can be cleared, however, if the problem has not been fixed the fault code will reappear prompting you to seek service.
Reset Inactive Fault Codes. Fault codes that indicate that there was a previous issue.
Clear first-time ‘Ghost’ Codes. To get rid of ghost codes, all you have to do is reset the fault codes with OTR Diagnostics.
What’s a ghost code? Specific trucks will display fault codes on the dashboard, and most of the time you’ll have a check engine light or a check module message. After this, a screen will appear stating that the error has occurred. Many of the codes that appear on your dashboard fall into the category of “ghost” codes, meaning that the fault code was triggered by certain conditions that are nearly impossible to recreate. To get rid of ghost codes, all you have to do is clear fault codes with the OTR Diagnostics and clears the DTCs once. Note that if the fault code comes back a second time, you do need to take the matter seriously.
Aftertreatment Commands
Forced DPF regen. A forced DPF regen is performed when a diagnostic scan tool, such as the OTR Diagnostics, starts the regen process. The DPF soot load could be too high for a passive or active regen to occur, meaning you’ll need to perform a forced DPF regen.
Reset Ash Accumulators. Ash accumulators have stored values in the engine control module (ECM). Ash level includes measurement of ash in the DPF.
Reset DPF Accumulators. DPF accumulators have stored values in the engine control module (ECM). DPF level includes measurement of soot in the DPF.
Reset Aftertreament Learned Data. Measurement of learned data based on various engine components to adjust your injection timing based on characteristics of your engine sensor values.
Reset DPF Regeneration Timers. Measurement of time since the last DPF regen occurred. The calculation is based on time, miles driven, and fuel usage.
*Available with Plus and Pro Subscription.
