Cannot Communicate with Emissions Testing Machine
Hey everyone! Having a hell of a time here with getting my smog test completed. Passed without issue last year, but this year it won't even talk to the emissions testing machine.
2008 RL w/Tech Package 100% stock
Here is what I have done/checked so far:
- Took it to 2 different emissions testing centers; Dekra and a local shop. About to take it to the exact shop I passed at last year, it's just far away.
- Completed 15+ different emissions tests over the course of 3 days, split across each location. They were slow, so the techs were nice enough to let me retest multiple times in a row.
- All tests gave the same "result"; "ODB (or maybe they called it a DAD connector?) connector has lost connection with vehicle or come loose from the socket..."
- Checked what fuses I thought could be related to this; all the ones I check were intact. Saw some info about it being related to the cigarette lighter/ACC fuse, but those are intact.
- No CEL's or SRS or any dash lights at all
- I have no issues with any of my systems. Maybe once every 4-6 months I'll get an alert saying "check VSA"; but that always clears itself within minutes and the dealer could not diagnose any issues when I had them check it.
- It wasn't recently in an accident or anything. Most recent work I did was replacing the fog lights, but that went flawlessly.
- I have the Bluetooth XM adapter unit installed in the trunk, but it's been there for a while and I've passed smog with it installed so I'm disregarding that as a possible cause.
- I have converted the AC controls to the 2009 version, works great never had an issue during/since the install.
- Handheld scanners connect without issue. Used both WiFi and cabled scanners. Neither device found codes or had any issues connecting to the vehicle or reading info.
- Removed the ODB plug from the metal mount under the dash, thinking maybe the mount was preventing a solid connection.
- Checked to ensure each cable in the harness, behind the ODB plug itself, is connected and seated properly into the plug.
- Completed fresh drive cycle, confirmed cycle completed, re-tested at both emissions stations; no change still "disconnects".
I called my local dealer and discussed this with them, they said they can hook it up to their scanner...but said their scanner was no different from the over-the-counter ones. I didn't feel like wasting $150 and a 50 mile trip on that, plus the service advisor was a total asshole to me on the phone...so I have not gone to a dealer yet.
Any help or advice would be greatly appreciated. Thanks!
