Where to hook code reader 2002 envoy
Your OBD II code reader won't work on that vehicle.
To get stored codes you need a OBD 2 reader or scanner. Or take it to local auto parts store and have them hook it up to there OBD2 scanner
If you are sitting in the steering wheel the hook up will be located by your right knee under the dash.
passenger side panel, above left knee
under the driver side of the dash, it is a square 6 pin connecter
you have to hook up a special reader to your computer to find out the code.
you get a code reader and hook it up to the fuse boc and it will say erase codes and u mass the green button.
The light will stay on until the trouble code is cleared from the computer. If you don't have a code reader that can clear the code, disconnect your battery for several minutes, then hook it back up. This clears the computers memory. If the light comes back on, you have another problem.
The obd2 plug is under the knee board (under the column).
The function of the hook is to get the attention of the reader.
