Can you clear codes with Snap-On MT2500?
I've been through every menu and I can't seem to find any way to clear the trouble codes on my '86 LG4 Iroc. I've tried with the car running and not but the clear codes option isn't in any of the menus. I know the MT2500 can do it on later vehicles.

I have the Snap-on MT2500.
You clear the codes on these earlier dumb ECMs by disconnecting the negative battery cable. It doesn't take very long at all.

I know I can do it that way. I was mainly wondering if my brick might have an issue with it not showing in the menu or if it's even possible to do at all while I'm already sitting there with it in my hands.

No the MT2500 can't clear the codes on these earlier ECMs. You aren't seeing an option for it because one doesn't exist.
