So far so good, got this to check S-VCM on my Honda Pilot 2022
I got this to check what my idle ECT1 temps are before the S-VCM install and after as I need to make sure the temp ECT1 sends is 165F to prevent the VCM from being able to engage. I like the graphing for it (so far, I think it can only graph one live data sensor at a time.) The custom view is nice too, where you check off only the sensor readings you want to see live. Can connect to the RS2 app with blue tooth from your phone to this once you pair it, which is simple 1. Plugin the 3040 to the obd2 port 2. On your phone, turn on blue tooth 3. Turn your car on 4. Open the RS2 app and choose connect to scan tool then follow the app instructions. I can't seem to pull reports yet from my phone from the device, have to spend more time with it, but it looks like you should be able to. I did get a red flashing EVA/CAT/EGR on a new car, not sure why, car has less then 260 miles, will call them and find out what it could mean. Update: Reporting does work, I just needed to exit and come back into the app. Just need to find out why those sensor reports are showing up as incomplete (see attached image)

Best for money
Love this, read codes and clear them, even though it doesn’t wipe every vehicles code it does majority of the brands we know and love. Not to mention great price for a tool that can scan and wipe codes.

Decent scanner but won't do everything listed even on models listed for
It ran scan on my 97 Silverado and said what parts needs fixing or replaced and listed the prices, waiting on parts to see how accurate... It mentioned how soon it needed to be done and future repairs depending on year and mileage that mainly depends on how well vehicle has been took care of... Wouldn't link up to read any ABS brake codes or brake system listed it would 96 or newer models...

Auch fuer amerikanische Modelle geeignet!
Mein Mann faehrt einen Ford F-150 und unser reader konnte den Fehlercode an seinem Truck nicht erkennen. Mit dem Innova OBD2 Scanner/Car Code Reader war der Fehler innerhalb von Sekunden ausgelesen und mein Mann wusste genau, was mit seinen Bremsen los war (was ja nicht unwichtig ist). Wir sind begeistert. Klare Kaufempfehlung!

Bon pour Mercedes 3500
Utilisé pour lire code de mon Mercedes 3500. Compatible mais ne lit pas tous les codes spécifiques. Facile à utiliser et permet d’effacer le Check engine. Permet d’évaluer l’importance de code pour mieux planifier les entretiens essentiels. Peut aussi donner les infos en temps réel ce qui est utile si on connaît bien son véhicule et les seuils à ne pas dépasser.

nice toy
I'm not happy that it does not support ABS live, however I read that it does in one of the Q&A before I order it. That needs to be corrected.
