#21
ok cool.. one more thing.... while im on it.. my bro has the car in okl so i cant check it right now... but his wheel hub making a ****ty sould like something engadging and getting stuck... from the drivers side... and the abs light shoot on and stays on also traction device messing up too all can be caused by bcm?
Back to the OBD II problem...
Are you getting power to pin 16 of the plug? It is the pin in the lower right corner of the plug as you're looking at it. Backprobe that pin with a test light or meter and make sure it is hot.
Here's a schematic and pin assignment for the plug:

The ABS and traction light both coming on are classic signs of a bad wheel bearing on these vehicles. That's where I would focus my attention.
