OBD-II Code Reader suggestion and info
 

Amazon has this code reader on sale right now but i am not sure if this is a smart buy. I have two 2002 Ford Focus and thought a purchase like this would be helpful. This particular code reader draws power from the Data Link Connector. Does the Focus provide power via the DLC? I know this reader isnt very expensive so I am not expecting it to do everything but can someone with experience in these tell me if they think this is a quality one.
