I have a 2012 Corvette grand sport that I?ve been updating the Tune on for a few months.
Tonight I went to update the Tune/flash. Half way through it stopped and said Timed Out. It?s done this several times before and all I do is restart the flash and goes right threw. Well it kept stating ?unlicensed vehicle?. I shut down the computer unplugged all the cables and tried again with the same fault message. I made sure the battery voltage is good, I checked the PCM fuses. The hp tuner scanner connects no issue and reads the codes. It gives code U0100 for pcm permanent failure. The car will not do anything when I try to start it and gives all kinds of error messages on the display of the car.
I?m on the most current version of HP Tuners. Laptop is charged, car is charged up.
Any suggestions?
