What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[wsteele]

I just found it exactly there. The dangling plug seems to come from the fans, which actually do run. I wonder if it was left over from the recall/upgrade and just dropped loose.

I just read that the wiring to the RVC sensor comes from the BCM. Maybe plug it back together and see if the code goes away? BTW, the code I think is specifically some sort of problem detected in the seat driver occupied switch, not sure how that might relate to the RVC sensor. Other than maybe a bad BCM or a problem in the wiring harness?

Installed one of these last night. See how good it works Saturday...

I bet it works fine. I have had one of these since my Yukon was new and it has served yeoman duty every single day I towed (which was a lot in the first half of the truck's life).

The RVC sensor is still plugged in okay. I was reading the Remy document and saw the parameters controlling charging, including underhood temp. The temp got pretty warm roaming Big Bend this weekend. I did not check the code again after I got home.

I also need to put the whole Tech2 spaghetti together and mess with it. Might be the first this I go look for. After programming my new key fob.

On the Tech 2, if you have a clone like mine, my issues all were related to cheap knock offs of the connectors from the unit to the CANdi and down to the ODBII port. I also read in the User manual that you should use the power port on the cable, versus the power port on the unit bottom next to the RS232 connector, for any power while the unit is plugged into the truck. Of course, the unit will get power from the ODB as well, if the battery is up to *****. But for some reason, unless you are running the unit not plugged into the truck, you shouldn't use the DC in on th bottom of the hand held unit (I can only guess it is ground related).

I’m trying to identify all the “stuff”. I’m guessing this thing is the candi unit?

YES

The left front blinker was hyperflashing, so I put a new bulb in... it's still hyperflashing. Tried another, the same thing. Ideas??

Check the rear.

Setting up my tech2. I’m drilling down through the vehicle options, Chevrolet, MPV, then it asks N200 or N300.

um Kay. Not sure what that means.
