Trying to flash a pcm on a 2013 dodge grand caravan. I can connect with the pcm through the Chrysler software ok and it finds an update for the pcm.  I click on flash and it downloads the update, sends it to the j2534 module and then starts to flash. It stops with an error message "flash failed timeout". Is this a known problem or has anyone else experienced it? Thanks. Patrick
