How do you select a vehicle older than 1996 with the Maxisys? I just got the Maxisys pro today, updated it, and was trying it out. I tried to see if it would get codes out of a 1992 Chevy truck, but I can't find anywhere in the scan tool to select a year older than 1996. I typed in the VIN and it doesn't decode or recognize it as a good VIN number. Loving the device so far, much better than anything I have used to date.
