The actual app
Diagnostics organized around the vehicle in front of you

Mechanic assistance
Readable code definitions, diagnostic priorities, likely causes, parts lookup, voice commands, and camera-based label/barcode reading.
Professional reports
Save scan history and export customer-ready PDF or JSON records for individual vehicles, shops, and fleets.
Compatibility before action
Review guaranteed, likely, and unsupported functions by VIN, year, make, model, adapter, bus, and gateway requirements.

Hardware and vehicle coverage
Know what the vehicle and adapter can actually do
Coverage varies by ECU, model year, protocol, adapter firmware, security gateway, and OEM authorization. Garage Monkey PRO reports those limits instead of promising functions the vehicle cannot perform.
Current focus
- Ford, Lincoln, Mercury, GM, Chevrolet, GMC, Cadillac, and Buick
- Chrysler, Dodge, Ram, Jeep, and Volvo passenger vehicles
- Toyota, Lexus, Scion, Honda, Acura, Nissan, and Infiniti
- Hyundai, Kia, Genesis, Subaru, Mazda, and Mitsubishi
- Volkswagen, Audi, BMW, Mini, Mercedes-Benz, and Sprinter
- Jaguar, Land Rover, Range Rover, and Porsche
- Isuzu and Hino medium/heavy-duty profiles
- Freightliner, Western Star, Kenworth, Peterbilt, International, Mack, Volvo Trucks, and Mitsubishi Fuso
Standard emissions OBD2 coverage is broader. Enhanced module and service-function coverage is vehicle-specific. Heavy-duty trucks require an OBD-reachable emissions controller or a compatible SAE J1939 interface for full network access.

Straight answers
Frequently asked questions
Does the app use simulated vehicle data?
No. Core diagnostic actions require a compatible adapter and a real vehicle connection. Saved reports can be reviewed later, but the app does not fabricate scan readings.
Can it clear codes?
Yes, where supported by the connected ECU. Clearing codes can reset readiness monitors or hide diagnostic evidence, so the app requires deliberate confirmation.
Can every supported vehicle perform a forced regeneration or reset?
No. Service functions vary by ECU, model year, protocol, security gateway, and adapter. The app uses compatibility and safety checks before offering a workflow.
Does it work without internet access?
Core adapter communication, saved records, bundled code information, barcode reading, and label recognition can work locally. Web pricing, cloud sync, billing, and some speech services require connectivity.
