I have a flashscan v2 and have been using it for a while with a aem uego wideband and eventually my connector that had the tx cable broke and i never messed with it until today. when i fixed it and hooked everything back up i cant get the flashscan to read anything.

nothing has changed from when it worked, i verified all firmware/software is configured correctly.
pinouts are correct( ground is pin 5, serial [aem blue wire] is pin 2)
i tested the aem with a laptop and it receives data over rs232
i went into the options > self test > external sensors on the flashscan and it shows my a/ds correctly but says zero for everything else
i tested continuity of all my cables and they are all OK

I cant think of anything else that it could be

Is it possible its a flashscan hardware failure? if so, can it be repaired?
