2007 Crossfire Skreem Code 2071-72
looking for some help with no start , if I disconnect battery and do a reset it will fire twice then set 2071-72 code. I can communicate with skreem module with dbr3 . I test can data lines to pcm ok . I am looking for info on how to determine which component is bad . thank for any help with this issue
Let's start with a VIN and if you have any codes to give direction. If you have the DRB III what does the scan data say. Is there a light On in the dash? Work related history. Give us ammo and we will help to load your weapon!!
With that code, it's almost always the SKREEM module, provided both CAN lines are up and power and ground are good. You can use a scope on the CAN, but a DVOM will work as well. If you've got a voltage difference across the two can lines of approx. .3-.4V, some kind of comm is happening.
On the Drb go to the no start screen and there should be a line that says something like fuel or theft allowed. From what I remember hope this helps
SKREEM module is located behind the cluster. With the drb3, go into the SKREEM module & check for com & dtc’s in the SKREEM. The 2nd pic u posted is a pic of the code in the pcm. Need to know if you have com with the SKREEM module through the drb3. If no com with skreem, as long as power, grounds & can lines test good, skreem is bad, which is common. If skreem is bad, the Bad news is…
I have comm with skreem and no codes
If you need a SKREEM, I just used this service. Worked as advertised. I access the SKREEM. If I have power and ground, I check for activity on the output while in crank position. If there is not any signal at all on my scope, I condemn the SKREEM. precisionecu.com/products/2004…
Thank you for suggesting precision ecu work out great
Glad it worked out. It’s a good alternative
Do you no what goes bad in skreem I have read chip info
the skreem‘s I’ve replaced have been due to complete no com with the skreem. Can u please post of pic of skreem module window on the drb3 showing no DTC? How many keys are present to the car? Next steps I would take are testing key signals on ALL available keys & antenna ring.
The key I do have does unlock and lock door with remote
Can you tell me if you only have to copy 68hc05x16 chip
Check with needswings.com they fix the Skreem modules.
Jeff, looking at service information on FCA the DRB III communicates via SCI and not on the CAN-C wires directly. The code you have is a hexa code. Look up procedure for a P2071 code. In a nut shell as Tim has stated check the powers and grounds and CAN-C and if they are in good sanding order replace the SKREEM
