OTR Remote Diagnostics

OTR Remote Diagnostics is a fleet diagnostic monitoring system. A device plugs into each truck's diagnostic port and streams data over cellular to a web dashboard. You can see fault codes, monitor engine data, and send remote commands (like forced regens) from anywhere. It's the same diagnostic intelligence we've built over six years with OTR Diagnostics, but now it works 24/7 without anyone being at the truck.

OTR Diagnostics requires a phone plugged into the truck. It's great for owner-operators and drivers who want to diagnose their own trucks. OTR Remote Diagnostics is always connected. It's built for fleet managers who need visibility across multiple trucks without relying on drivers to plug in and check. You can see what's happening with any truck from anywhere, and send commands (like forcing a regen or resetting fault codes) remotely.

Those are telematics platforms. They're built for compliance, location tracking, and driver behavior. They tell you where your trucks are and whether drivers are following HOS rules. They're good at that. OTR Remote Diagnostics is built for diagnostics. We tell you why your truck is going into derate, what's actually wrong with the engine, and we let you fix it remotely. We're not trying to replace your ELD. We're filling the gap your ELD can't fill. Your telematics system might tell you a truck has a check engine light. OTR Remote Diagnostics tells you it's a P20EE code, SCR efficiency below threshold, you've got 100 miles until derate, and here's what you can do about it right now. Most of our customers run OTR Remote Diagnostics alongside their existing ELD because they solve different problems.

Yes, OTR Remote Diagnostics requires a 2-truck minimum. It's designed for fleets, not single-truck operations. If you're running one truck, OTR Diagnostics is a better fit for your needs. That said, the real power of OTR Remote Diagnostics is seeing patterns across your fleet: which trucks keep having the same issues, where your maintenance dollars are actually going.

OTR Remote Diagnostics supports: Detroit Diesel DD13, DD15, DD16 (2011 and newer), Cummins ISX, X15, ISB, ISL (2011 and newer), Paccar MX-13, MX-11 (2011 and newer), Volvo D11, D13, D16 (2014 and newer), Mack MP7, MP8 (2014 and newer). If you're running Class 8 trucks from the last 10-15 years, we likely support them. If you've got a mixed fleet, we can look at your specific trucks and tell you exactly what's covered.

OTR Remote Diagnostics monitors the truck's engine and aftertreatment systems. It does not monitor trailers, reefer units, or trailer ABS systems.

It plugs into the truck's 9-pin or OBD diagnostic port. Takes about 10 minutes per truck. No shop time, no downtime. We include detailed instructions with every device.

No. OTR Remote Diagnostics is a diagnostic tool that plugs into the standard diagnostic port. It does not modify any truck systems. This is the same port dealers and shops use for diagnostics.

Yes. Contact our support team to reassign a device to a new truck. We'll update your dashboard to reflect the change.

You'll receive an immediate notification that the device was disconnected. You'll also see exactly when and where it happened.

Depending on engine make and model, you can: Force a DPF regeneration, reset fault codes, clear certain derates, and view live engine parameters. Not all commands are available on all engines. Check with our team for your specific trucks.

Alerts are sent within seconds of a fault code triggering. You'll know about problems before your driver calls you.

OTR Remote Diagnostics monitors trends in your engine data (soot levels, temperatures, regen intervals) that signal developing problems. Our AI diagnostics help identify issues before they become breakdowns. We're not just reading codes. We're watching the data that leads to codes.

OTR Remote Diagnostics provides full diagnostic information, not just code numbers. You'll see what the code means, what typically causes it, whether it's likely to cause a derate, and recommended next steps.

OTR Remote Diagnostics stores data locally on the device when cellular coverage drops. Once the truck returns to a coverage area, all stored data automatically syncs to your dashboard. You won't lose any fault codes, alerts, or diagnostic data during the outage.

OTR Remote Diagnostics uses multi-carrier cellular connectivity to ensure the best coverage across the continental US. Cellular service is included in your subscription.

OTR Remote Diagnostics only tracks location when the truck ignition is on. When the truck is parked and off, location updates stop.

No. OTR Remote Diagnostics draws minimal power and has smart sleep features when the truck is parked. It won't drain your batteries even after extended periods of sitting.

You do. OTR Performance does not sell or share your fleet data with third parties. Your diagnostic data, fault history, and truck information belong to your company.

Yes. All data transmitted from OTR Remote Diagnostics devices is encrypted. Data stored in our cloud is protected with industry-standard security measures.

OTR Remote Diagnostics monitors the truck's diagnostic systems, not driver behavior. It tracks fault codes, engine parameters, and vehicle health. It does not record audio, video, or cab activity.

Yes. You can configure which team members receive alerts for specific trucks or groups of trucks. Send driver alerts to dispatch, critical derates to management, and maintenance codes to your shop.

OTR Remote Diagnostics currently works through a web dashboard accessible from any device with a browser. A dedicated mobile app is coming soon.

Yes. You can export fault history, maintenance reports, and fleet health summaries from the dashboard.

OTR Remote Diagnostics works alongside your ELD but doesn't replace it. Your ELD handles compliance (HOS, logs). OTR Remote Diagnostics handles diagnostics. Different tools for different jobs.

No. OTR Remote Diagnostics works alongside your existing ELD or telematics. Most of our customers run both because they solve different problems.

The hardware is purchased outright. It's yours. No leasing, no equipment return requirements.

Your subscription includes: 24/7 diagnostic monitoring, cellular connectivity (no separate data plan needed), dashboard access for your team, fault code alerts, remote command capabilities, AI-powered diagnostics, GPS tracking, software updates, and customer support.
