I just bought a 2003 avalanche, and I took it to have an emission test done, but the OBD connector was no where to be found, does anybody have a clue where it could be. The manuals that I looked at dont help. And why would someone move it or take it out.
diagnostic connector missing on 2003 Chevrolet Avalanche 1500
Asked by for the 2003 Chevrolet Avalanche 1500
The Chevrolet diagnostic connector ( OBD ) should be in plain view just below the steering column and just below the trim panel. You may have to remove the panel and see if someone has broken its mount and just stuffed it up in there somewhere! Hope this helps!
