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…

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…

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.

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
