They make an O2 Cheater that helps eliminates the code without a tune. About 35 bucks for a cheater. If you are looking to save a couple of bucks for now.
As for the ABS Light ... mine is out as well. It is a sensor on your brakes. Can't really be reseted. I tried. Just need to replace the sensor.
I stopped bothering with it for me, I autoX my SVT and I've fixed the sensors with a mechanic twice and after 3 events each time ... the sensors go out. So I just left it out.
In TX, I can pass inspection with the ABS light on.
