2017 Jeep Grand Cherokee. EVO -All Inside Firmware 69.06 Hardware inside 7.0
CHR7A wiring harness. Installed according to directions and got the lights on the EVO-All as shown. DCRYPTOR process seemed to be successful.
Vehicle starts then stops within 1-2 seconds.
Are there any settings/options I should be setting?

I will try to assist you but first I need to know the S/N number on the back of the module?

Next please turn on option d1.11 and then re test and let me know if that keeps it running.
When I change options do I need to need to load the DCryptor or do I just make my option changes and select save options?
Nope, simply turn the option on, click save and re test in vehicle.
Turned on d1.11 on.  No diference.

Turned on d1.11 on.  No diference.. still ran briefly then shut off.

Got it working.
Ended up turning off A7, A8, A9, and A10.  (Brake , door and trunk monitoring) . Remote started and kept running. Turned back on A7 thru A10 individually with it starting and running successfully each time.  With them all turned back on it is working as desired.  I'm not sure what the difference is but it is working.

Turned on A4 and turned 0ff A6 and A6 so that the rear defrost automatically would come on with remote start.  It is not but the air conditioner would turn on.

I then flashed the Firmware back to 69.06 as it states it fixes a climate control bug.  It still starts up correctly and runs as desired and the Rear defrost turns on also.... Not the AC.
