The software upgrade that Chrysler performed addessed a DTC P0688 ECM/PCM power loss sensor/open relay, which totally shuts down the car. If I down-grade, wouldn't there be the potential to have the same failures? I would hate to go back to the dealership with the same problem and they notice the ...

I spoke with your tech support on the phone, they said I had to wait for a new release to be written. This is Chrylser's latest software update to an "H". No time frame was given. Tech support recommended that I do not downgrade per the programmers message.

Thanks!

Looking for guidance on next steps.
