Volvo | OTR Remote Diagnostics
Already have an ELD plugged in? No problem.
OTR Remote Diagnostics installs alongside your existing ELD at the diagnostic port. We include a free splitter harness so both devices connect to your truck. No conflicts. The device connects over cellular, so every command you send and every data point you see travels through cell towers. No WiFi needed. No Bluetooth range limit. Works anywhere the truck has cell service.

Running Volvo trucks without visibility is costing you.
Volvo aftertreatment systems are complex. When they fail, they fail fast. Without live diagnostic data, you're always reacting.
Volvo's 5 MPH derate is brutal
Volvo doesn't give you a gentle warning. It goes from running to 5 MPH lockout fast. By the time your driver calls, the truck is already stranded.
DPF regens failing silently
Volvo trucks need regens, and when they don't complete, soot builds until the truck derates. Your ELD has no idea this is happening. OTR Remote Diagnostics tracks soot load in real-time and lets you force a regen remotely.
DEF system codes are expensive
Volvo DEF quality and NOx sensor issues are the #1 reason for unplanned shop visits. A single DEF-related breakdown costs $3,000 to $5,000 when you add tow, repair, and lost load. The warning signs were in the data days before.
Common Volvo fault codes you'll catch before they become breakdowns.
These are real fault codes from Volvo D11, D13, and D16 engines. OTR Remote Diagnostics reads them the second they trigger and tells you exactly what to do.
| Fault Code | Description | OTR Remote Action |
|---|---|---|
| P20EE00 | SCR NOx Catalyst Efficiency Below Threshold | Force DPF Regen |
| U029E00 | Lost Communication With NOx Sensor B | Remote Reset |
| P24A400 | Diesel Particulate Filter (DPF) Restriction / Soot Accumulation Too High | Force Regen |
| P204F94 | SCR System Performance Dosing Failure | Force Regen |
| P220164 | NOx Sensor Circuit Range/Performance | Remote Reset / Forced Regen |
Volvo-specific commands. From anywhere.
Every command OTR Remote Diagnostics sends goes directly to the Volvo ECM. Not broadcast data. Not surface-level readings. Direct communication with the engine computer.
Reset fault codes
Clear active and inactive fault codes at a dealer level. Same reset your Volvo dealer runs with Premium Tech Tool, done remotely from your phone.
Force DPF regen / SCR Regen / Crystal Sublimation Regen
Initiate a forced DPF regen, SCR regen and Crystal sublimation regen all remotely. Monitor exhaust temps, soot level, and regen progress in real-time live data from your dashboard.
Reset aftertreatment
Reset DEF quality, SCR efficiency, and NOx sensor readings. Eliminate cascading derate codes without sending the truck to a dealer.
Derate alerts
Get notified the moment a Volvo truck starts a derate countdown. Act before lockout, not after.
Live engine data
Stream 30+ parameters in real-time: soot load, DEF level, SCR efficiency, exhaust temps, boost pressure, EGR position, coolant temp, oil pressure.
Reset Exit inducement
Exit the 5 MPH derate lockout remotely. Clear the inducement state and get the truck back on the road without a dealer visit.
How much is one breakdown actually costing you?
Now multiply that by the number of unplanned breakdowns your fleet had last year. Most of them started with a fault code that was visible in the data days before the truck went down. Nobody was watching.
