GODIAG Breakout Box -OBD2 Protocol Detector Car Test Box for OBDII Protocol Communication Detection/ECU Tool Maintenance/Diagnosis/Programming/Coding

Just a heads up, this does not come with instructions. I kinda knew what I was doing but I had to do some googling. Basically this is for diagnosing your car when you have a check engine light, it can also reset the check engine light. Another cool thing this tool does is that it can save your settings on your radio when you change your batteries. I was also able to use this without having to get a scanner. This tool has the potential to save money on diagnosing car issues and repairs. Mine has worked well with great accuracy.

Great product for doing diagnostics, vehicle immobilizer & security work whether it be on the bench with the included power adapter or in the vehicle with the OBD II port supplying power.With expensive scan tools these days I always use this to verify that the networks are communicating properly and that there is proper power and grounds being supplied to the box assembly. You don’t want to hook your very expensive scan tool up and it be fried because you didn’t have the proper powers and grounds from somebody’s previous shoddy work on a vehicle.I have multiple brands of Breakout boxes and this is the easier one to use wit additional features for doing ecm, ecu repair on vehicles.Please make sure you’re fully aware of the capabilities Nd use of this product as with little or no experience just as with other tools, equipment you can do thousand of dollars to a vehicle if not properly trained or knowledgeable with what you’re doing.

Works great for offboard programming. The power adapter didn’t work but I found another lying around the house that works.

Purchased this for a friend and he was pleased at the fast delivery, quality, and price.

works flawlessly!

Great

So much better than trying to poke around the OBDII. Also shows you if your grounds are good. More than I need because it also can help program ECM’s. Only down side is there are no instructions but they are online

The pins on the unit's OBD2 cable were too large and wouldn't allow me to connect to any OBD2 plug on a car. I tried it on multiple vehicles to no avail. Compared them to the pins on my Snap-On scan tool OBD2 plug, and they looked significantly wider. I didn't want to force it in and damage the vehicle connector.Manufacturer never got back to me about a replacement cable, so I am sending back to Amazon. Taking a hit on a restocking fee, but without this cable, it is a paperweight.

Justamente hoy lo recibi buen enbalaje pero al momento de probarlo la pantalla del voltaje no enciende ya realize varias pruebas y sigue sin encender la pantalla de voltaje una pena

quality product

We were having problems getting our OBD2 reader to connect fully to the van, kept getting a can-bus error. There were a couple of things that needed done such as turning off the airbag light and doing a full diagnostic, there were also niggling power problems too, but we couldn’t get any further than the error. We had checked wiring as much as we could physically but it’s a maxus and the wiring is a mess. My partner removed the ecu and performed a bench test using a Vident scanner and the Godiag breakout box, turned out to be a corroded pin that was preventing the communication. Great outcome and saved a fortune. My partner is enjoying his “new toy” and exploring all the features. Even more so with my car as he says it’s a lot less boring lol. Fantastic bit of kit and you don’t need an expensive scanner to pair with it.

This item arrived safe and well packaged.This is a great device for any car owner interested in fully maintaining their car. It can read any ECU for Maintenance / Diagnosis / Programming / Coding of any fault codes - which is a service usually requiring a mechanic and some kind of large fee!This really is the easy way to ask your car questions like "what's up?".It can be operated by almost anyone - if you're able to plug it into the socket in the foot well, then you can work this. Perfect for pointing you in the right direction with just a little training - I suggest watching a few 'how to' videos as they give you so many great tips.I wouldn't wait until the car breaks... have it handy in the toolbox and use it to keep your car driving perfectly.I highly recommend this product.

Not sure in this one yet. In theory it's a lovely device. Intuitive and actually fairly well layed out. However the quality is a little 50/50. Using it in a professional environment, we'll see how long it lasts. Did potentially cause some interference when CAN sniffing something with no OBD.
