Re: How to Repair Relay Control Module (RCM) - (Mystery no Start)
I bow to your wisdom, intellect and kindness for having patience with a newbie. It fired right up but I must say I don't have a lot of confidence it won't quite again. Go big or go home. Heading to the store with it. I guess I need to just get back on the horse.
Again, thank you.

He looks normal but is probably a little too crisp inside.

Try this :
Unhook the negative battery cable.
Turn the key all the way on and leave it for 15 minutes or so.
Turn the key back off.
Hook the battery back up.
Try it. ( and may the odds be forever in your favor )
This will heretofore be known as the "Universal Crossfire Reboot" or "Cure for the Crossfire Blue Screen"
This has been reported to work for others with the three strike and you are out scenario.

If it isn't, maybe we should add it under the specific identifier. 
Later,

Time will tell if it works, we can only hope.
We have had some good posts on repairs that cost too much when buying new parts, maybe this is one of them.
I have to rearrange the Index of repairs, it is getting too large and needs some subdivision.

And keep in mind that a car that needs the reboot is also a car that you might want to really consider the condition of the battery, or at least battery terminals and ground cable connection. When a battery ages, it looses some of its ability to filter the noise and 'bumps' or ripple from the alternator - and such perturbances in the 12 volt supply can irritate the microprocessors in the ECM and BCM.

What Mark is saying is that Crossfires are basically all-electric cars that just happen to have an additional fossil fuel engine. If the electric ain't right, it ain't going nowhere.
Kinda makes me long for the old Piper Cubs that had NO electrical at all. ( except for the magnetos ),
or the '62 Triumph Bonneville motorcycle I once had. The battery went south in it and I went to work every day for 2 weeks until payday when I could afford a new battery.
Engine ran fine with the magneto, just didn't have any lights ( including brake lights . We don need no stinkin lights !

Well it isn't fixed, I still get the three strikes and you are out. I thank you for the reboot information as I have had to use it a couple times. What I am wondering is if I buy a new circuit board my problem will be solved??????????

By three strikes and out are you referring to the car cranks but doesn't start three times and then never cranks again?
I don't recall you mentioning that before, that is the SKREEM module, RFID chip in the FOB or antenna ring issue. Totally different symptoms then the relay module no crank. Odd you have it running on 8-28 but now have SKREEM issues. Have you done the sticky key repair and not put the antenna ring back on? This is a common missed step, making sure the antenna didn't get pulled from the SKREEM.
You mentioned door lock issues, were you diving into the dash behind the instrument cluster? Door remote is SKREEM related, you leave something disconnected?

List them and I'll update my post. ( Before you say it, I'm too lazy to look up that other thread and figure it out. )

Re: How to Repair Relay Control Module (RCM) - (Mystery no Start)
OK, Here's all the text :
I called my local dealer, quoted me $200 for Skreem.
Asked for my vin number, and car mileage.
Ordered it, came back in 3 days.
Package wrap said came from MB in Texas for Chrysler.
I plugged it in.
Put back the instrument panel and lower panels.
Turned the key with battery disconnected to drain capacitors.
Then connected battery, turned key to on position for several minutes, sounded like things were reprogramming themselves, then turned key off for one minute.
Then started car as normal.
Fired right up on first try.
Drives great again.
Total work time to do it, maybe an hour and 10 minutes.
And the 3 day wait for the new Skreem to arrive.
No core required for old Skreem, no core charge.
Just $200 part plus tax.
Done deal.
Hope this helps.

Re: How to Repair Relay Control Module (RCM) - (Mystery no Start)
Just out of curiosity...how absolutely necessary is it to disconnect the battery before swapping the RCM?
The reason I ask is a few nights ago I had the no-start issue while leaving a resturant. I'm 95% certain it's the RCM, plus I've been having occasional P0410 triggers anyway. I carry a brand new MB spare with me but I did not have the right socket for the battery terminal. While checking everything and deciding if I would try to swap it without a battery disconnect my Crossfire decided to start and drove home just fine.
I got home and made the swap. I'll work on shipping the old one to tighed1 next week.

Don't know that it is absolutely necessary. I have swapped mine plenty of times checking the fix I have done for others.
Never had any problem, never saw any sparks when connecting cables.

Not necessary. Have swapped hundreds w/o disconnecting the battery.
