Default TECH2 Scanner Tool Needed NoVA/DC/MD

Hi everyone. I’m a new C5Z owner and having a heck of a time getting it to emissions tested because the EVAP and CAT systems are “not ready.” Supposedly a TECH2 tool can be used to to overcome this by enabling “Service Bay Test.”

I’m hoping someone in the DC area with a TECH2 (or clone) is willing connect so my C5Z can get inspected and registered.

I truly appreciate any assistance! Thank you in advance.

Here is the Corvette specific info for each monitor you're having trouble with. I see no reason the catalyst won't set if you've driven it off idle for enough time. But, the EVAP could be troublesome in very hot weather.

I used a regular scanner to check my emissions systems. I reset my emissions monitors by performing a drive cycle reset. Google the procedure. Did it before taking the car back to get it emissions tested.
