Diagnostic Platform · v2.209 · Live

A diagnostic library for every bay.

23 systems · 1,168 error codes · 439 procedures · 68 schematics

The RV Tech Suite collapses the manufacturer-PDF rabbit hole into one offline app that installs on desktop and mobile alike. Brand-specific diagnostic flows, audited wiring schematics, step-by-step procedures, error-code lookups, and field-confirmed known-issue notes — across the systems and brands that actually roll into a service bay. Built for working techs and the shops they run.

Inside the Suite

What a working tech reaches for, in one tab.

Six tools built around the way work actually moves through a service bay — diagnose, look up, fix, document. No tab juggling. No signal. No excuses.

Diagnostic Flows

Interactive flowcharts that branch on what you're actually seeing in the bay — not generic "check the fuse" copy-paste. Brand-aware paths route you through the right test for the right component, then drop you straight at the procedure that fixes it.

338 Flows 322 Symptoms Brand-Aware

Audited Wiring Schematics

68 schematics redrawn from manufacturer originals and verified side-by-side against the source PDFs. Pan, zoom, and trace clean, readable diagrams instead of squinting at a fifth-generation fax. Covers HVAC, electrical, slide-outs, water heaters, inverters, monitors, and more.

68 Schematics Audited Pan / Zoom

Procedures + Known Issues

439 step-by-step procedures — calibration, adjustment, reset, programming, mechanical — plus 270 field-confirmed known-issue notes with workarounds and the model-year context that matters. Filter by type, search by keyword, jump straight from a diagnostic node into the fix.

439 Procedures 270 Known Issues 240 Inline Links

Error Codes + Components

1,168 manufacturer error codes — Dometic, Coleman-Mach, Furrion, Atwood, Suburban, Truma, Aqua-Hot, Onan, Victron, Magnum, Lippert, and more — each mapped to its meaning, likely cause, and the procedure that resolves it. 1,041 catalogued components for parts-lookup and ID.

Field Calculators

Nine working calculators built into the Suite — the math you'd otherwise do on a notepad or in a separate app: Ohm's Law, wire / voltage drop, fuse and breaker sizing, battery bank, runtime, state-of-charge, propane consumption, solar sizer, and inverter sizer.

Offline-first PWA

Install to the home screen on iOS, Android, Windows, or Mac. The entire library — all 23 systems, every schematic, every code, every procedure — caches locally on first load. Works in the back of the lot, under a slide-out, in the cell-dead corner of the shop.

See it in action

Same library. Desktop or phone.

Install once on the device you actually carry. The Suite runs as a full installable app on Windows, macOS, iOS, and Android — same library, same offline cache, same workflow. Park it on the shop computer for the lookups that need a big screen, and on your phone for the work happening under the coach.

Desktop · Browser or Installed App

Mobile · iOS or Android

Desktop

Install on Windows or macOS for the shop computer. Pan-and-zoom schematics. Full-resolution dashboards. Side-by-side reference and procedure panes.

Mobile

Install on iOS or Android. Same library, same data, same offline cache. Drop it in your pocket and walk it to the unit on the rack — no signal needed.

Offline

After first load, the whole library caches locally on every device. Works in the back of the lot, under a slide-out, in the cell-dead corner of the shop.

By the numbers

A library built for the real bay.

The Suite isn't a wrapper around someone else's PDF dump. Every system, every schematic, every procedure was sourced from manufacturer documentation, curated, cross-checked, and rewritten in a format you can actually use under a coach. Here's what's inside today — and it grows release over release.

Built for techs · Loved by shops

One tool that pays off for the bay and the books.

The Suite is built for the tech actually doing the work — and that's why the shop running them benefits too. Faster diagnostics, fewer return trips, newer techs ramping up against the same canonical references the veterans use.

For the Technician

Stop hunting. Start fixing.

You already know how to wrench. What you don't need is to spend twenty minutes Googling a fault code, finding a forum thread from 2018, and guessing which post is right. The Suite puts the diagnostic flow, wiring diagram, error-code meaning, procedure, and known-issue note all one tap apart — and works under the slide-out where there's no signal.

Brand-aware diagnostic flows route to the right test, fast
1,168 error codes with meanings and fixes — no more sketchy forum threads
Audited wiring schematics — clean traces, not 5th-generation fax PDFs
439 procedures linked directly from the flows you're already running
Works offline. Install once, never lose the library
One library across every brand you'll see in the bay

For the Shop

More units through the bay.

The Suite is a force multiplier on every tech on your floor. New hires ramp up against the same diagnostic references the veterans use. Diagnoses land on the right component the first time. The shop ships work faster, with a paper trail that holds up on warranty disputes.

Faster diagnoses → more units shipped per tech per week
Consistent vocabulary across the team — every tech reads the same flow
Ramp-up window for new techs measured in days, not months
Coverage across every brand on your work-order queue
One subscription per tech — no enterprise sales call required
