I have a vcx nano running on a windows 10 64bit laptop. It took me a little while to get it up and running right. As far as I can see everything including special functions work fine everywhere. I only seem to have issues with the service bay evap test. Basically the test will not run to completion no matter what. If I select the actual year of the vehicle at the part where you set parking brake and start vehicle it instructs to start vehicle and allow 2 minutes of run time, then tap the accelerator. If i follow these instructions, and press enter, when it goes to the page that shows all the evap data pids it either doesnt show the evap test active at the bottom or sometimes is does briefly and then says test complete, but doesnt update the service monitor and also doesnt allow for the engine off natural vacuum portion. If I change the year of the vehicle to one year older it gives the prompt to start and raise rpm to 1800-2200 for the duration of the test, but when i do this and press enter or press enter and raise rpm it doesnt run the test completely. There are no dtcs or anything that should be interfering. If anyone can shed some light I would appreciate it. I have plenty more info of many different ways I attempted the test to see what happened.
