High discharge pressure → condenser
Pinch to zoom · ask the AI
ALM 10 = high discharge pressure. Check condenser airflow and discharge service valve; verify fan rotation. Sources cited from your TK manual [1][3].
Everything you need, right in the truck.
Purpose-built for field service — fast, reliable, and grounded in your actual manuals. It works the way technicians actually work.
Smart alarm lookup
Look up any Carrier, Thermo King or Schmitz Cargobull alarm code and get the real description, severity, likely causes and manufacturer guidance — plus an AI explanation of how to fix it. Codes stay available offline.
AI repair guide
Ask any repair or how-to question. The AI (xAI Grok) searches your service manuals and answers step-by-step with citations you can tap to verify — never a random guess.
Wiring diagrams + AI
Real wiring & schematic diagrams organised by unit model. Pinch, zoom and pan into any section, tap “Explain” for an AI walkthrough that reads the actual drawing, and ask it questions about the circuit.
Open unit downloads & AI-analyze
Pull a Carrier unit’s on-board download straight into the browser — no separate TRU-Tech laptop needed. The AI then reads the temperatures, alarms and run data and tells you what it means. Opening Thermo King downloads is supported too and improving fast (beta).
Carrier, Thermo King & Schmitz Cargobull
Full support for both major reefer brands, kept strictly separate — brand-specific alarm databases and manual libraries so answers stay accurate to the unit in front of you.
Install-free web app
Open it in any browser on phone, tablet or laptop — nothing to download from an app store. Add it to your home screen and it launches like an app.
Fleet-controlled access
Licensed per fleet, not per tech. Admins add or revoke technician access in seconds, so access follows the fleet — not an individual’s personal device.
From alarm to repaired, fast.
Pick your brand
Choose Carrier, Thermo King or Schmitz Cargobull. The app loads the right alarm database and manual knowledge base for that brand.
Look up the alarm
Enter the alarm code for the full description, severity and causes — then get an AI explanation of the fix, cited from the manual.
Open the diagram
Pull up the unit’s wiring schematic, zoom into the circuit, and ask the AI what any part of it does.
Fix with confidence
Follow grounded, step-by-step guidance and tap the source to confirm against the manual before you wrench.
Technicians deserve better tools.

Built with reefer techs in mind.
“Instead of hunting through paper manuals, the AI tells me what to check and in what order — with the manual page right there to confirm.”
“Zooming into the wiring diagram and asking the AI what a connector does is a game-changer on a tight engine bay.”
“Alarm code, cause, and a cited fix in seconds — on my phone, no install. Exactly what a field tool should be.”
