On my 2005 STR if I wanted to put the shocks on the stiff position temporarily to see how it handles, is there a relay I would pull? Would I get a code if I did this? When I am done just put the relay back in, no problem?

 

i think if you unplug each of them at the top they default to firm
i think you will get a CATS fault on dash and a code also. Pulling the cats fuse or relay should do the same
