I was trying to flash in a new cal in my pcm this morning before I went to work. I was using v2 without my computer attached.
There was a fault message about the boot loader and after that the pcm stopped responding. Same code if I tried to read fault codes, flashing cal or full flash. ($0281). The V2 did not get any respond from the pcm at all and the engine did not start.
After work I checked that the v2 had the latest updates and copied the files to it again. I hooked up a power supply on my battery with 14.2 V. Still it was no response from the pcm. I left the car with the ignition on for an hour or so, still no response.
I hooked up my laptop to the v2 opened the scan 7.5 and went to the “program pcm with currently loaded calibration”. As I usually do, I pressed the check status button before I tried to program the cal. There was some communication with the v2 and then it stopped with a red line at the bottom telling something like no response.
Now I was sure that I was the proud owner of a new doorstopper.
Then I tried to press the button ones more. The fuel pump started, the program windows showed communication, and it said ok at the end. I started to program the cal, everything went ok and the car started as normal.
