2015 Jeep OBD2 Pre-Install Question

Post by CColotti » Wed Apr 04, 2018 9:06 am

I have read a few posts about the OBD2 connector getting messed up when it is disconnected from the connector for another device to use it. I also read from a number of posts from Dara DeGrand that this is a specific issue with Jeeps when it is disconnected while the radio is on. This will be an Alpine i207 setup.

My question(s) are:

- Is it better to just hard wire the two leads from the unit? The connector seems clunky anyhow to be just hanging off the port
- Can splitters https://www.amazon.com/gp/product/B00W2 ... 79MV5N3YQW be used instead?

Will either of these solutions prevent it from getting "disconnected" and prevent having to reset the Maestro module? I am looking for a set it and forget it install.

A reset can be done in the radio menus and takes maaaybe 30 seconds once you know where to find it, so it's not that hard to do, if you need to do it. I don't recommend hardwiring or using a splitter, because often times, the vehicle can only send to one scan tool at a time. Even if you do use a splitter, the vehicle will likely stop sending information to one device, so there's not really a way to avoid it.

Hmmm...so the problem still exists with Jeep and the disconnection?

I was also trying to find a more elegant way to connect other that hanging the plug off the port which seems a bit wonky :)

The issue is fixed. However, if it's constantly being unplugged, there is still potential for the OBD to need a little nudge to start reading again, and a reset will take care of that.

Also for the $12 that splitter may still be worth trying to see host it tests out with multiple devices. It's short money to clean up the install a little potentially.
