Jeep Wrangler going all crazy when trying to remote start, please help!

Question

OK I have a remote start system that has just started causing all sorts of problems (at least I am assuming).  I have the Fortin Evo All with the Chrysler harness in my 2014 Wrangler.  It is tied into an Avital alarm.  This has been installed since August 2014.  Over the last 2 months or so, on occasion teh vehicle will not remote start, either by the remote of by the Viper Smartstart cell module I have installed.  I noticed after the non start event happened, the alarm would also not lock the doors and turn on the factory alarm system, I would have to set the factory alarm after setting the Avital alarm.  The remote start has not been working now for the last 6 days, so today I decided to sit in the car and see what happens when I try to remote start.  See this Youtube video.   https://www.youtube.com/watch?v=BT2r_aO1JlQ&feature=youtu.be      The last few days every time I have played around with the remote start, I have then been getting a check engine light with a slew of codes.  See attached pic for the latest list.   I am able to clear the codes and they do not come back, unless I try and remote start.  Hoping maybe you have an idea.  Thanks!   Ray

I should add I have an appt with the alarm installer next Friday, but want to bring it to him with as much info as I can.

When the issue does happen, even if I do not use the remote start (which is when all the codes and MIL show up), the Avital alarm will not lock the doors, it just arms the Avital, and I have to use the factory key/fob to lock the doors.   Not sure if that info helps at all.

This is actually helpful. Either the Avital was not communicating with the EVO-ALL or the EVO-ALL was not communicating to the car. Add that to all those codes in that picture you had posted and my finger is starting to point at the T-harness. Wish i had a direct answer for you but that's all I have at the moment.

Sorry had not mentioned that sooner, just thought of it while trying to go through every motion in my head lol!    If the T harness is disconnected, you have to do all the programming steps again correct?  Wondering if I should just pick up another harness, and if it happens again just swap it.

The EVO-ALL will stay programmed a verrrrrry long time after being disconnected, so you shouldn't need to reprogram it. You can, but you don't really need to.

I never asked you this, but the Jeep is automatic transmission right?
