Alright here is what I found.
Foot off brake, ignition to ON. No automatic engine start message. (First time I recall seeing this message in the truck)
Foot on brake, ignition to ON. Automatic engine start message received.
I verified my ‘22 will also start without my foot on the brake during the automatic start countdown. I think that’s the first time I’ve waited for the WTS to extinguish (aside from a remote start).
For those of you that are having random auto be no-auto starts I suggest slowing down on brake to button, press the brake wait a second and then press the button. I bet the issue goes away.
I just checked mine and that is indeed how it worked, at least this time.
Because I have the grid heater disconnected, I have to be wary of the preheat cycle completing. With foot off the brake, if I press once the dash just comes to life but no preheat. If I press the button a 2nd time with foot off the brake, it seems like more stuff awakens and the preheat cycle will run but the truck won't start.
My question for anyone who knows for sure is when you press the button the 2nd time, even with foot off the brake, does more stuff on the truck reall start up? You, know like the old keys where turn it to the first spot and acc is on, turn it one more click and more stuff comes on, turn it past that point and the truck started. I can play around with it today but I seem to remember that there are a few things that won't work unless you press the button a 2nd time. (Maybe windows?)
If I ever do press the button a 2nd time, I have to remember to really start the truck and let it warm up because if the preheat countdown completes with the GH disconnectd, a CEL can come on.
