No Start - Need addition solutions
Re: No Start - Need addition solutions
My experience, I ran into the same problem, dealership replaced SKREEM but didn't know what they were doing. Think the original SKREEM they put in, somehow burn't out the PCM. They had to put in another SKREEM and PCM. It took me 6 months to get my car back from dealership. In Boston area, Mercedes dealers will not work on a Crossfire. Was a total nightmare.
Except I'm out of extended warranty and the PCM is only covered under Federal Emissions Warranty 8 years from start of factory which is also expired.
Re: No Start - Need addition solutions
PS: I was lucky mine was covered under warranty, dealership told me over $4K was invoice. Unfortunately this was the second time I had the SKREEM problem. First, happened in November 2013, then again in Dcember 2014. Hope everything works out for you,
Re: No Start - Need addition solutions
**Second Update**
Service manager called to tell me the second SKREEM module still does not fix the problem. They are being told from Chrysler engineering you need to replace the PCM as well with the SKREEM module.
I'm being told I need to pay $3,300 for a new PCM and there are only 3 available in the whole US. Which to be honest I cannot afford and it would be ashame to get rid of this car with only 48k miles on it.
I find this hard to believe. Is there any info I can print out for any possible other solutions?

Re: No Start - Need addition solutions
Does anyone know when you read the VIN # from the SKREEM module does it show the full VIN for the car or does it only show partially?
The tech mentioned on both NEW modules it only reads "1C3" the first 3 digits of my VIN #. Also with the new modules the car will no longer do the "3 crank and quit" sequence but, with my old module it does.
Tech says the PCM needs replacing. To me it sounds like the PCM isn't recognizing the SKREEM module because of the VIN?
Basically they cannot do anything more for the car without a new PCM. I tried looking around but, only find one for $2000 (MODULE. Powertrain Control made by Mopar. #05189967AB)

Remember the PCM you buy must be the same as the one on your car, one from another model will not do.
Re: No Start - Need addition solutions
The VIN number is programmed into the SKREEM and is not visible. The numbers you can see show that it is the correct part, but it will not function as it s VIN number programmed in it does not match the chip in the fob, your fob chip matches the VIN in the original SKREEM module.
Remember the PCM you buy must be the same as the one on your car, one from another model will not do.

Re: No Start - Need addition solutions
The fob is already coded to the VIN.
eBay TC modules, some are listed here. This may list in Canadian dollars.

Re: No Start - Need addition solutions
After testing the PCM all the pins I found pin 35 (Ground Fault) has no voltage. Looking at some diagrams that pin sends to the pulse module and then to the starter.
Going to crack open the PCM and follow that pin and see if any fuses/resistors are bad. Hopefully this solves my problem. I think I have better luck fixing the PCM that trying to find another one. Literally after hours could not find one anywhere.
I still have a suspicion about the key transponder is bad. Unlocking and locking the doors would rule that out right?

Re: No Start - Need addition solutions
Ok I was able to obtain a salvaged ECU from a wrecked crossfire. Thanks to the crossfireshop.com!
This weekend I installed a new battery and new batteries in the FOB. The alarm sounded as soon as I hooked it up and noticed fuse #9 was missing so that made sense why.
I put a spare 10amp fuse in #9 but, the dom lights and locking/unlocking the doors still worked which I don't understand why.
As far as voltage testing I'm not getting any voltage out of the pulse module nor any going into from the ignition switch. Could a faulty ignition switch cause a no crank??
If not my only option is to get the salvaged ECU reprogrammed with my VIN# and hopefully things connect.

Re: No Start - Need addition solutions
This is exactly what is happening to me. Car died with the same symptoms over two weeks ago. Reading here I suspected the SKREEM and told them when I towed the car in. This is a Chevy dealer I bought the car from and bring it to them so I don't have to pay a deductible with my extended warranty. They then sent it to Chrysler since it was electronic related and nothing mechanical they can do. Two weeks later, Chrysler agrees with me, it's the SKREEM. They are saying the chip in my remote went bad too, and when they replace the SKREEM with one they have in stock, I need a new key and to get it programmed. They have this in stock too. But the warranty company says they won't cover the key, only the SKREEM. Chrysler says the car will not work without a new key and having it programmed.
Talking with a few others online, they agree, the SKREEM needs to be VIN programmed, not off the shelf. They suspect the dealer has one sitting there with a key that was sent for another car and trying to unload the set. With the proper VIN programmed SKREEM, my old remote should work, and if the chip inside is actually bad like they claim, my second remote should work, correct? No keyfob programming needed?
What is confusing here is I see instructions on how to program our keyfobs, but I also see the above post saying how the keyfob is also VIN set and can't be. So I'm confused, what does the programming actually do that is posted in the tech section, if that fob needs to be VIN specific?
Fueling up on all my info as I bring the second remote in tomorrow. I'm out of work right now with unemployment running dry. Don't have the $210 for a new keyfob and programming. Glad the $600 SKREEM is covered, this was why I bought the warranty knowing Mercedes parts are expensive.

Re: No Start - Need addition solutions
And here's a little more from the service manual..
The SKREEM retains in memory the ID numbers of any ignition key transponder that is programmed into it. For
added system security each SKREEM is programmed with a unique secret key code. This code is stored in memory,
sent over the CAN data bus to the PCM, and is encoded to the transponder of every ignition key that is programmed
into the SKREEM.
In the event that a SKREEM replacement is required, the secret key code can be transferred to the new SKREEM
from the PCM using the DRB IIIT scan tool and the ignition key system replacement programming procedure.
Proper completion of the ignition key system initialization will allow the existing ignition keys to be programmed into
the new SKREEM so that new keys will not be required. In the event that the original secret key code cannot be
recovered, SKREEM replacement will also require new ignition keys. The DRB IIIT scan tool will alert the technician
during the key reprogramming procedure if new ignition keys are required.
The sentry key system performs a self-test each time the ignition switch is turned to the ON/RUN position and will
store fault information in the form of Diagnostic Trouble Codes (DTCs) in SKREEM memory if a system malfunction
is detected. The SKREEM can be diagnosed and any stored DTCs can be retrieved using a DRB IIIT scan tool.
Refer to the appropriate diagnostic information.

Re: No Start - Need addition solutions
Vin specific and "pre coded" I can't swear to.. Like you that is what I've heard. One guy on face book claimed he purchased a skreem.. plugged it in and all was fine.. I find that hard to believe myself. I don't know that you could purchase a "virgin" skreem.. and as noted they program the keys into the skreem.
Re: No Start - Need addition solutions
After 9 months the car finally runs. I had no luck finding an independent shop that had the right diagnostic tools or the proprietary software for this car. I was denied at a few dealers, most shops wouldn't even entertain the thought either.
The process to figuring out what was the exact problem was extensive and also very mysterious. There was no starter ground coming from the PCM to the pulse module and no positive feed from the pulse module to the start itself. After replacing the pulse module there still wasn't any ground coming from the PCM and that was also replaced. New keys were ordered and the PCM, pulse, SKREEM were all communicating with no problems. (These parts were replaced individually once and then a second time to be programmed all at once).
The problem was my "original key", lock cylinders and door locking module were not matching/cut per my VIN. The new keys they ordered off my VIN would not turn the ignition in the car. They would open my glove box but, wouldn't start the car or manually open the doors. My old key would do the exact opposite but, now the SKREEM, PCM and pulse were programmed to the new keys.
They had to take the metal blade from my old key and put it in the electronics of the new key to get the car to start. Basically they believe at one point the key, ignition cylinder, door locking module and possible the PCM, SKREEM were all from a donor crossfire.
I've had this car when it only had 400 miles on it but, I bet ill never figure out if it was stolen beforehand or had these parts replaced before I bought it. Since I've never had any problems with the key, ignition cylinder or door locking module I'm positive it wasn't tampered with during ownership.
The bill I won't disclose is massive due to it being at the dealer but, at this point I needed the car back!

Re: No Start - Need addition solutions
Very glad to hear your back up and running and I can relate to your frustration. SKREEM, PCM must be big problems on our cars. My experiences, Chrysler Dealer had to replace SKREEM and PCM 2 times within 2 years. Second time was a disaster, had it on lot for 7 1/2 months, seems like most repair shops don't want to be bothered working on XCross.

Hopefully through our problems/experiences with our cars it will help educate the dealers and owners in the future when these bizarre occurrences happen.
They didn't seem to have many problems replacing/reprogramming the cars but, when something doesn't match up it throws everything off.
Did you have a warranty on those parts for the second time they failed? I was told the parts have a 2 year/24k warranty.

Re: No Start - Need addition solutions
They were telling me they only see mismatched keys and ignition cylinders with a theft recovery or R-title vehicle. It literally is mind blowing.
