Code Reader required for OBD2?
Speaking of sensors & engine codes, could I post a question here about retrieving engine codes off of my 2001 Blazer 4x4, 4.3L V6. I fairly new to this site, sorry if I,m in wrong area-perhaps someone could redirect me if it's in wrong place. Do I need a code reader to get codes for this, it has the 16 pin ALDL diagnostic connector equipped with OBDII. Is there a way to jump say a A & B connecter like my 92 Cavalier?

You definitely need a scan tool to read codes on an OBDII equiped vehicle. There are a few exceptions where you can read the codes through the driver information center (some Caddys), but the vast majority require a scan tool.
BTW, I have moved your post into it's own thread.

I am not 100% but I thought you could jump A&B on plug and count the flashes on check engine light and retrive codes. like one flash then a pause then three flashes would be code 103, I might be way off here.

Not the OBD2 equiped s-series trucks.

Yes, on my 1992 Z24 I can jump A&B connectors to get the blink code. However, on '97 Blazer it has the OBD11 which has a different diagnostic connector requires the scan tool. Thought there might be a way to do a MaGiver but may have to ask the Fiance for my wallet & buy a scan tool !
