OBD Diagnostic Scanner

A plug-in OBD scanner that snapshots subsystem health, then maps damage to fault codes and the exact component to repair, with the code-mapping owned by the server.

PRODUCTION-SHAPED, the reference Lua is validated and written framework-correct for ESX, QBCore, and QBox, ready to drop into your server.

Description

A plug-in OBD scanner that snapshots a vehicle's engine, body and fuel-tank health, then returns decoded fault codes naming the exact failing component and severity. The damage-to-code mapping lives only on the server, so the scanner is a real diagnostic step rather than a client-readable cheat sheet.

Known Failure Modes & Corrective Prompt

  • Client-side decode, the mapping ships in the client so players read which component to fix without scanning. Keep the decode table server-only.
  • Unloaded scan anim, TaskPlayAnim runs before the dict loads, so the plug-in gesture never plays.
  • One-sided round-trip, the analyze/report events are registered on a single side and the snapshot never reaches the server.

Corrective re-prompt: Move the decode table into the server analyze handler, register analyze/report with RegisterNetEvent + AddEventHandler on both sides, validate type(snapshot) == "table" server-side, and load the scan dict with the while not HasAnimDictLoaded(dict) do Wait(0) end loop before TaskPlayAnim.

Framework Integration

  • ESX: portable via exports["es_extended"]:getSharedObject(); require an "obd_scanner" item before the scan event fires.
  • QBCore: resolve with exports["qb-core"]:GetCoreObject(); gate the scan on the mechanic job and surface codes in a qb-menu list.
  • QBox: use exports.qbx_core with ox_inventory to require the scanner item and ox_lib:notify for the readout.

Profit Potential

$150-$2000/mo on Tebex (expected ~$510), priced inside the $50-389 script band against a corpus of comparable Tebex sellers (median ~$11.85K/mo); steady, under-served diagnostic depth lands mid-band.

Trend Signal

→ stable, inferred: Diagnostic depth is steady and under-served by shallow repair scripts [inferred].

Sales Angle

Sell the depth that one-tap repair scripts lack, a scanner that names the exact failing component turns repairs into a skilled diagnostic job. Recommended Tebex price $69.
