What Shawn said - here in Atlanta pretty much any code will cause you to fail emissions because the shop won't continue doing the inspection until the code is cleared - it's not that it's part of emissions, but that it's causing a code to appear. My thought was more general in that many states require a general safety inspection, where an ABS light would most likely cause a failure due to safety concerns. That's why I said you should check the local inspection regs.
