Disassembly often makes the obscure clear... Congratulations!
I'm having the same problem. Thanks a bunch guys, not I know how to fix it myself. My local shop says 6 to 10 weeks after dropping off the unit to them, absurd!Aloha!
So, this course of action led to a successful resolve.
Behind the Remote Start plug in, I found a bit of corrosion on the Brown/Blue terminal, 12VDC positive. Pulled it apart cleaned completely, recrimped with DiaElectric grease applied. Put it back together. iMonitor came on, and KeySwitch and Push Start work perfectly. No die outs, after 1-1/2 hour run. I'll be putting it back in service later today!
I really appreciate all the expertise!
