I recently uploaded a File to my ECM and now the SES light flashes really fast and the fans constantly run. Did I kill the Flash memory? Is there anyway to reset the PCM? I removed the PCM from the car and have been using it with my OBDII PCM for now

 

Can you give us a few more descriptions? (Probably a dumb question, but....) does the car run with the programmed PCM?

I have ruined a few PCM's in my day and each one acted different upon crashing. However, none ran my car.

No it doesn't start at all just a real fast flashing SES and the fans run

 

Joe,
the chips will definetely need to be reflashed...
That's exactly how it behaves when the programming has been interrupted or some other errror occured during the upload.
