My 2014 C-Max Hybrid SE has two OBD ports. It is my understanding that one port is for the engine and the other is for the battery maintenance system. My question is this: Do both ports provide the same information that the Automatic requires to work properly? Or only the port designated for the traditional gasoline engine?

Hi Nick! Welcome to the community. Quick question, is your 2014 C-Max a plug-in hybrid?

Thanks for the quick reply!
No. It's just the standard model hybrid

That's fine. I didn't expect anything until Monday anyway. Enjoy your weekend!

Hello again! First, our technician would like to say thanks for taking these photos and for posting this here in the community. We knew there were instances of two connectors existing in plug-ins, but this was the first we have seen with a standard hybrid.

So some clarification, while both of these ports appear to be "OBD-II ports," they are both technically J1962 connectors (which isn't the same thing as "OBD-II"). From these photos, only the white connector appears to be "OBD-II compliant." This is also the port that you've been plugging the adapter into, yes?

If you're willing to try it out, we're curious to know if the adapter beeps at all if you plug it into the other connector. We're not certain that this connector would even provide power to the adapter.

I actually have been using it in the other port since Sunday (for curiousity's sake). The data being relayed so far looks pretty reliable, although I still don't know if the Automatic can pull engine codes from that port. If you'd like, I would happily provide your team with some data from each port to compare (if you think it would help in your continuing development of the device, apps, and service).

If you're interested in becoming an Alpha tester for us, we'd be happy to send you some more information. This would involve you deviating from the functionality of the product a bit, but our engineering team would appreciate the help :)

Just send a message to support@automatic.com and mention this topic, and someone will follow up with more details via email.

If it will help your company continue to develop and support your products, then I will certainly consider it. I've sent an email to the address you provided and will return to this thread (or start a new one if need-be) if and/or when I see a check engine light come on to test if the engine code is received.

Thanks for all the speedy responses and friendly support!
