Chevy Express 3500 won't get past smog test Sign In

I have a 2002 Chevy Express 3500 5.7L 212k miles
Like a knucklehead, I made the mistake of cleaning the battery connections before I took it in for a smog test. So now I need to do the GM driving cycle a bunch of times. Problem is, I don't have anywhere to do it and be able to follow the parameters to the letter.
My question is: Will putting the rear axle up on jack stands to do the driving cycle work?
