Tech2 Evap Service Bay Test

I have a 2004 Corvette. I’m trying to get my EVAP monitor ready asap

i connect a VXDIAG VCX Nano and use option 2000-2003 corvette because 2004 option doesn’t have service bay test.

when following instructions I get this error

is it because my car doesn’t support this or am I doing something wrong? I have two VCX nano devices at this point lol… 1 USB & 1 wifi version

&& both say EVAP service test is not available.

im At my wits end trying to get this solved

does anyone know how to fix this

I’d try another bidirectional scan tool that has the service bay test if you can find or borrow one.
