Hello,
I have in my shop a 2005 Cadillac CTSV that apparently has a bricked/dead PCM after a HPTuners flash. The PCM initially scanned, the cal was modified and flashed to the vehicle. Upon the initial fire up the car started and idled, after one touch of the throttle the engine turned off, the coolant temp gauge climbed to max, the car won't restart and it will not let me connect/flash via the VCM editor (2.23) using either 'Calibration only" or "Write Entire" I think it's either step 3 or step 4 that fails.
Anyone have any advice, run into this issue or know how to fix this?
