Everyone else reports the problem.
OTR helps you fix it.
A scanner reads a generic code. Telematics tells you where the truck is. A dealer will fix it, on their calendar. OTR reads the real SPN and FMI fault, then hands you the dealer-level command to act on it. Force a regen, clear a derate, decide drive versus repair. From your phone, or from a dashboard watching every truck you own.
A dash light is the cheapest part of a breakdown.
The light is free. Four bills arrive between it and the truck earning again, and OTR is built to remove the first three and stop the fourth from repeating.
The tow
A heavy-duty tow runs several hundred dollars on its own, before a tech has even looked at the engine.
The dealer bay
Then you wait for an open bay, and pay a diagnostic fee just to read a code you could have read yourself.
The downtime
Every day it sits, the truck payment, the driver and the missed load still come due.
The repeat
A code clears, the underlying issue does not, and you pay the entire bill a second time a few weeks later.
Everyone else either reports the problem or charges you to handle it.
There are four ways to deal with a fault code, and three of them leave you waiting on somebody. OTR is the only one that reads the real fault and acts on it where the truck is parked.
| Capability | Dealer service | Generic OBD scanner | GPS / telematics | OTR |
|---|---|---|---|---|
| Reads real SPN / FMI fault detail | Yes | generic codes only | — | Yes |
| Forces a DPF regen | Yes | — | — | Yes |
| Clears speed / power derates | Yes | — | — | Yes |
| Alerts you 24/7, before the driver is stuck | Yes | — | location, not faults | Yes |
| No appointment, no shop visit | — | Yes | — | Yes |
| Helps fix the problem, not just report it | Yes | — | — | Yes |
| Who you reach for help | varies by shop | you are on your own | call center | Detroit team that built it |
From fault to fixed, without the truck leaving the lot.
This is the part a generic dongle cannot do. Watch a real fault move from triggered to resolved.
The fault triggers
The engine ECM throws an SPN and FMI code. On a normal day, this is the moment a dash light appears and the guessing begins.
OTR reads it instantly
The device reads the exact fault. For fleets, the cellular unit pushes it to your dashboard the second it happens, 24/7.
You act, remotely
Force a DPF regen, clear the derate, or decide drive versus repair. From your phone or the dashboard, no bay required.
The driver keeps rolling
What would have been a multi-day dealer wait is handled in minutes. The load arrives, the truck keeps earning.
What the old way is costing you per year.
Adjust the sliders to your operation. This is a conservative estimate of what you spend on dealer diagnostics and recoverable downtime, the money OTR is built to keep in your pocket, netted against what OTR costs.
The next fault is going to happen either way.
The only question is whether you read it and act on it, or pay somebody else to. Both products carry the 60-day money-back guarantee, so finding out costs you nothing.
