August 4, 2026
BEYOND THE ENGINE Your check engine light was only ever half the story. OBD2 Ninja now reads the modules the OBD-II standard never covered: • ABS and stability control • Airbag (SRS) • Power steering • Transmission, climate, hybrid and body modules These use manufacturer-specific addressing that isn't published anywhere, so it works on some vehicles and not others — and the app tells you which rather than showing you an empty list. Toyota, Lexus and Scion are supported by name. On other makes it searches the vehicle's data bus for modules, which takes about a minute and only runs while you're parked. Codes come back with the status the module actually reported — whether a fault is failing right now or was stored months ago and hasn't recurred — instead of a guessed severity. Chassis and body codes are manufacturer-specific, so the app shows you exactly what the module said and doesn't invent a repair for it. READ-ONLY, BY DESIGN This never writes to a module, never clears a chassis code, and never attempts a security unlock. Searching for modules is blocked unless the vehicle is stopped. HELP US ADD YOUR VEHICLE There's no public list of these addresses. Every one the app knows came from a real scan on a real car. So when a module can't be read, you can send us what happened — the addresses tried and exactly what each one replied. You see the whole report, in full, before anything sends. It carries your vehicle's year, make, model and engine, and a nine-character VIN pattern shared by every car of that specification. Never your full VIN: the characters identifying your individual car are dropped before anything is written to disk. Nothing else about you or your phone goes with it. Anything found this way is also remembered on your device, so the next scan of the same vehicle skips the search entirely. ALSO IN THIS RELEASE • Every module scan can be exported as text, raw replies included, to hand to a shop or to us. • The adapter log now captures module traffic alongside OBD-II commands.
