OTR Diagnostics for iPhone

Product summary

OTR Diagnostics is an iPhone application from OTR Performance Inc. that provides heavy-duty truck owners and technicians with an accessible diagnostic toolkit. It’s built to help you address issues such as failed or stalled DPF regens, persistent warning lights, fault codes, and unexpected power derates — all without depending solely on dealer service bays.

Notable companion app

• RemoteBoot WOL — free

Core capabilities

• Execute service actions remotely, including initiating a forced DPF regeneration and running other essential commands.
• Decode and explain fault codes so you can understand probable causes and likely repair or parts needs.
• View live telemetry so you can watch critical parameters in real time and spot problems early.
• Maintain a historical log of fault events and commands to reveal patterns and recurring faults.

Live data examples

Monitor ongoing engine and aftertreatment metrics such as:

• Boost pressure
• EGR valve position
• DPF fluid level These live readings help you diagnose trends before they escalate into roadside failures.

Why it’s useful

• Empowers truck operators to perform many troubleshooting and maintenance tasks independently, reducing downtime and service costs.
• Provides diagnostic detail comparable to dealer-grade tools, helping you decide whether a repair requires a shop visit or a parts replacement.
• Lets you anticipate and prevent issues through continuous monitoring instead of reacting after failures occur.

Vehicle coverage

Compatible with a broad range of heavy-duty platforms, for example:

• Volvo
• Paccar
• Mack
• Cummins
• Detroit Diesel
