APP FEATURES
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 5394 | FMI 3
- Aftertreatment diesel exhaust fluid (DEF) dosing valve
- 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.
Fault code history and command history
Quickly reference recent fault codes, how often they occured and date stamp when it first occured.
View commands with status history for how long forced DPF regen lasted, clearing fault codes and reset aftertreatment status.
Display Parameters
Live data is information that gets updated in real time. This includes vital information about your engine and your aftertreatment system. The live data fields will be updated in real time through the Bluetooth connection.
Why is live data important? Live data is an important feature that can help solve an intermittent issue or it can be used to get more information from your aftertreatment system during a DPF regeneration.
Some of the parameters you can track with OTR diagnostics include
- DEF Fluid Level
- DPF Soot Level
- EGR Value Position
- Aftertreatment Exhaust Temps
- Battery Voltage
- Boost Pressure
- Accelerator Pedal Position
- Engine Fuel Delivery Pressure
- + many more

United StatesThe best software tool
Using this item, I have already saved thousand of dollars, right before I ordered it I was going to bake my filters because my truck wasn’t regening and they where going to charge 5k at the shop and first day I got it I lowered my spot level to 0% and had no problems with my truck ever since!!!! Would recommend to everybody who has a fleet or truck!
United StatesSo far so good
Hooked it up for the first time today just to look it over. So as of right now with having no issues the device looks like it does a lot in will save me money
United StatesOtr diagnostic
I haven't personally used it bought for my son who has had many issues with paacar Regen system. Has been able to do forced Regen s and loves the way he can monitor everything.
CanadaOTR diagnosis
Love it. Which I could have access to the parameters settings
United StatesHighly recommended
Works as easy as 123
United StatesSo far so good.
The tool has done exactly what I expected it to do. Very satisfied.
United StatesGreat product
Paid for it self fist day
United StatesAwesome!!!
It does what it promises! Very handy tool to have especially for a Paccar owner. It saves time, trips to a mechanic and most importantly money!! Faults codes are explained in layman’s term so you know exactly what to tell your mechanic. The only thing I wish it could do is to tell you what your parameters should be. I think knowing this can give you an overall picture of how healthy your engine is and what issues you can avoid in the future with the proper tune up and maintenances. Overall it’s a must have!
United StatesFive star review for a 5 star prosuct
Purchased 4 units to keep in each truck and have had to reset 2 in the last two weeks, time saving tool and it definitely works as promised it would, I need more black stickers to put on my trucks
United StatesOwner opp
Awesome does everything they claimed it would do
United StatesProduct and price
I want to give the product 5 stars but the only reason I’m giving 4 stars it’s because when I purchase the product I clearly ask the person in the phone if I need to purchase the subscription every year he made it sound as if I didn’t. But then I got an email saying to renew the subscription I will have to pay another $600 dollars after 12 months ok he could of said it’s gonna cone out of your credit card every 12 months. Now I got to say at the moment the product has help me a few times I’m pleased about that. They could also include a digital diagram of the engine and help you to localize sensors location and all that.
