Reads the car Writes to the car, always confirmed first
Full ECU scan
MopCoder tries every module your model can have, from the engine and gearbox to the airbags, cluster and radio, and reads the stored faults from each one that answers. Faults come with a plain-language description, most urgent first.
Coding and feature activation
Coding opens on the values your car is set to right now, in groups, with switches and value lists instead of hex. Procedures walk you through each activation step by step. Every write names what will change and waits for you to confirm.
Looking for PIN codes, key programming or module replacement? See service and security
Real names from the modules MopCoder reads. Your car shows the ones its modules were built with.
Service and security
Read the PIN code, program keys, align a replacement module and run the service procedures, with the conditions each one needs checked before it starts.
Read the security code, add or remove keys, and get a replacement immobiliser working with the car.
Make a used or new module part of the car it’s fitted to.
The resets and routines that follow a service or a new part.
The jobs you do with the car on stands.
Unlock a radio and set it for the market it lives in.
Health report PDF
Turn a full scan into a clean A4 PDF. Share it with a buyer before you sell, ask a seller for one before you buy, or give it to your mechanic so they start where the car left off.
Every system checked
With its result: faults found, clean, no answer or not probed.
Every fault code explained
Description and status: warning light, confirmed, active, pending or stored.
Nothing hidden
Modules that didn’t answer are listed apart, so silence never passes for a clean result.
Before and after a repair
Compare two scans in one report: cleared, still present, and anything new.
Live data and actuator tests
Pick the values you care about and MopCoder reads only those. On Dodge, Jeep, Chrysler, RAM and the Italian brands, each one gets a dial and a graph, and you can record a drive and play it back.
Every control in MopCoder is coloured by what it does to the vehicle. Learn three colours and you know what’s safe to tap before you tap it.
Live data, fault codes, module identity, the VIN. Nothing on the car changes, so tap anything.
Coding and actuator tests. You see what will change and confirm it before a single byte is sent.
Clearing fault memory, resets, recovery. The app says exactly what you’ll lose and waits for you to confirm.
It goes in the OBD port under the dashboard, usually by your left knee. Turn the ignition on.
Tap Connect. MopCoder reads the VIN and selects your model, or you choose it from the list.
Start with a full scan, export the PDF, then open any module to change its settings.
Here are 206 popular models from 15 brands, with the platform code next to each name so you can tell a Charger LX from an LD. The app’s full catalog holds 335, including regional and commercial versions.
Pick a brand, or search across all of them.
MopCoder works with the common Bluetooth and Wi-Fi adapters. The difference is which of your car’s networks they reach: engine faults work on all of them, body and comfort modules don’t.
Bluetooth
Our recommendation. Reaches every bus an FCA car has, including the comfort modules on MS-CAN. Pairs once in iOS Settings.
Bluetooth LE or Wi-Fi
Reaches MS-CAN and is the only adapter that talks natively to the 50k body bus.
Bluetooth LE
Quick to connect and reaches MS-CAN. CAN only, so older K-line modules are out of reach.
Bluetooth LE or Wi-Fi
Fine for engine faults and live data. Most can't switch CAN bus, so some body modules stay silent.
No adapter yet? Choose Demo when you connect and explore the app on a simulated car.
Vehicle catalogs, module definitions and fault descriptions ship inside the app, so scans, live data and coding never go through a server.
Security seeds, computed keys and PINs pass through memory only and are kept out of every log the app can share.
Because the data is already on your phone, a scan works just the same in a garage, a field or an underground car park.

An iPhone, the MopCoder app and an OBD-II adapter plugged into the port under your dashboard. With the ignition on, open the app, tap Connect and pick your car, or let the app read the VIN and pick it for you.
Yes. Choose Demo when connecting and the app simulates a vehicle, so you can walk through modules, faults and coding before you buy an adapter.
Any tool that writes to a module can. MopCoder confirms every write and names what will change before it sends anything, and it refuses when it can't be sure of the exact bytes. Keep the battery charged and never unplug the adapter while a module is writing.
On Dodge, Jeep, Chrysler, RAM, Alfa Romeo and Fiat modules, MopCoder keeps an automatic backup in Recovery before it writes, and Chrysler-family body computers can save their whole configuration and restore it later. On Renault-group cars, note the original value before you change it.
On Dodge, Jeep, Chrysler, RAM and Fiat-group cars, yes: MopCoder reads the PIN from supported RF hub, WCM and body computer families, then uses it to program, enable or erase key fobs. If your module family isn’t supported, the app says so and sends nothing. On Renault-group cars it offers key learning on supported modules and steering lock immobiliser resets, but not PIN code reading.
That’s what the module replacement procedures are for: secret key transfer, VIN write, proxy alignment and, for instrument clusters, writing the odometer to match the car. On Renault-group cars, the used body computer and airbag crash data resets prepare a second-hand module.
The core is the same: full ECU scan, fault codes, health report, coding, procedures and actuator tests. Live data on Renault, Dacia and Nissan shows values without graphs or recording, and backup, radio code and proxy alignment are for Dodge, Jeep, Chrysler, RAM and the Italian brands. The table on this page lists every difference.
No. Vehicle catalogs, module definitions and fault descriptions ship inside the app. Your VIN, your faults and your drives stay on your iPhone. Security keys and PINs are never written to a log.
For Dodge, Jeep, Chrysler, RAM, Alfa Romeo and Fiat, an OBDLink MX+. It reaches the comfort and body modules that cheaper ELM327 clones usually can't.
Search the vehicle list above. If your model is listed, the app has its modules. What each module offers depends on the exact version fitted to your car.
Download MopCoder, pick Demo, and see what it would show you about your car before you buy an adapter.
