I read the 01 LB7 we bought tonight, and got a weird VIN number. ????i?B??C???0?&J is what is in the VIN box, I read it twice to make sure, and had the same results twice. I went on a test drive and logged it, I received the same vin message with the scan tool connected to the ECM. Any ideas?? My next day off, I am going to go to the dealer and make sure that the ECM has the latest OS from GM. 15188873 is the OS.
