2007 Compass OBD2 connection error
I have an odd problem with a recently acquired 2007 Compass Limited. The MIL is lit and my Innova code reader errors out on trying to link. The Innova works fine on every other vehicle I have so I don't think it's the reader. Kinda surprised to see it only had contacts in pins 4,5,6, 14 & 16. I verified 12v at pin 16 and pin 5 is grounded. I just now see that I needed to verify pin 4 as grounded so that remains a wildcard in this. I'll have to go back and check that but the wiring and overall condition is good, this thing doesn't appear to have been beat on. It otherwise runs/drives fine but I'll need to fix the MIL to pass emissions. Anyone see something like this before?
Confirmed pin 4 is grounded
