Mechanic RP on most FiveM servers bottoms out at a repair animation and a health bar. The OBD Car Device script goes further: it gives mechanics and vehicle owners an actual diagnostic interface — scan a vehicle, read stored fault codes, check live engine data, and push custom faults from external scripts like your mechanic job. It’s the difference between “your car is damaged” and “fault P0171: fuel system lean, engine temperature at 97°C.”

What the OBD Script Adds

Players or mechanics use a configurable item to scan a nearby vehicle. The scan returns stored fault codes from a pre-built library of 10+ codes, plus real-time readings for engine state and vehicle component data. Beyond diagnostics, the script includes a mod application system with 15+ pre-built modification slots — mechanics can apply coded upgrades and record them against the vehicle’s OBD profile. Custom faults can be injected via export from any external script, so a crash event in your driving physics script can automatically write a fault code that shows up the next time the OBD device is used.

Phone integration is a differentiator here. The script supports lb-phone, lb-tablet, yseries phone, qs-smartphone, and gksphone — so the OBD reader can live inside a player’s phone rather than as a standalone menu, which keeps the interaction pattern consistent with how your players already interact with the world.

Key Features

• Vehicle fault scanning with 10+ pre-built fault codes
• 15+ pre-built modification slots — fully expandable via config
• Real-time live data monitoring for engine and vehicle state
• Custom fault injection via export — compatible with external mechanic scripts
• Full localisation system — all UI strings translatable
• Phone integrations: lb-phone, lb-tablet, yseries, qs-smartphone, gksphone
• Partially accessible code — frontend and config adjustable
• Approximately 5,000 lines — a production-weight implementation
• Framework-agnostic via the free kq_link compatibility layer

Framework and Dependencies

The OBD Car Device uses kq_link, a free open-source bridge layer, for framework, inventory, notification, and dispatch compatibility. This approach means the script works with ESX, QBCore, or any other framework without requiring separate builds. Install kq_link, configure your framework in its settings, and the OBD device picks up the integration automatically. The t1ger_mechanic script has an official integration that writes fault codes from mechanic job actions — a good pairing if your server is already running that resource.

Where This Fits in Your Server Economy

If your mechanic shop currently handles repairs through a basic job script with no inspection layer, the OBD device adds the diagnostic step that makes mechanic RP feel like a real trade. Players bring vehicles in, the mechanic scans them, reads off codes, and works through a repair list rather than just holding a button. For servers that want high-effort civilian jobs, that workflow depth is what separates a busy mechanic shop from a repair kiosk that nobody uses.
