Can a pro read my plugs for me?

[Ryan Casey]

Some condensation out the tailpipe is normal. Are you losing coolant?

Well I filled the coolant and some disappeared but it's been sitting an inch below the full like for like 3 months and hasn't moved

Just keep an eye on it. If its losing coolant then you would want to check to see if you have Castech heads that might be leaking otherwise I wouldn’t worry. If you want more info on that, google GM Castech heads.

Ok sounds good, thanks. I do have another question maybe u can answer.

My battery went almost dead, it wasn't enough to run the computers or the lights on the dash or in the cabin but for some reason it was still able to turn the car over...

I replaced the old battery with a nice red top optima and it fires instantly, but now I have an airbag light on and I read on another form that cranking under voltage can set off the air bag light but they never said how to fix it.... Any idea?

I have a blue driver scanner just for reference and it says it does abs and airbags

What specific codes are you getting for the airbag?

You need to read the codes just like any time you have the CEL on. Without codes, there’s no way to troubleshoot. Hook up that scanner and see what it says. I use a Tech2 and have used it to troubleshoot an open wire in my airbag SDM harness. I have no idea why your light is on- could be anything.

I ran an all systems module scan and took a screenshot, then cleared them, then started the engine and did it again, here is the before and after...

This is different airbag codes then I was getting before and I have no idea what these mean. Hopefully y'all know what's up with this.

I replied to Fless above.... Check that out for the details, Thanks!

 

[Ryan Casey]

Based on thoes codes..m did I fry an airbag sensor when I was cranking under voltage?

Also if somebody wants to chime in on thoes other codes I'll owe them a beer

I'm almost 100% sure thoes are factory so 15 years old and 220k miles on then

Those plugs were introduced in the 2010 model year, replacing the 41-985s used previously. So they are likely less then ten years old.

From what I see you have a problem with the third row right seatbelt pretensioner circuit, and had a history code for the middle one but it cleared. I would check the airbag wiring connectors for that seat belt - unplug them, clean them, reconnect them. Also try pulling the seatbelt out and retracting it a few times. Might climb in there and go through the motions. It could be that the system just needs to recalibrate. You can also disconnect the positive cable off the battery and touch it to the negative battery post to discharge the system then reconnect it. If these don’t work then you’ll need a good bidirectional scanner like a Tech2 that will let you test all the components of the airbag system. Oh, and I quit drinking 12 years ago so you’re on your own with the other codes. Lmao

That could be, the last owner had very detailed dealership service paperwork and there was never a sparkplug change and he said he didn't there there was a change either but who knows for sure

So here's the real issue.... My third row seating is the bench style that comes out in one piece, the seatbelts are built in to it and there's no wires going to the seat....

A quick Google of your issue found this forum thread. It sounds like this might be a front impact sensor or wire going to it. There’s another that talks about this being a ghost code because a guy in a standard cab pu got this code and it said third row seatbelt, but when I google those codes I get front impact sensor not third row seatbelt like your scanner says. That’s all I got. You can probably do a better search. https://gmtnation.com/forums/threads/service-air-bag-with-code-b0077.18451/

Unheard of.............plugs lasting 220 K miles, performance would be down, along with gas mileage.

 

[OR VietVet]

Plus they would not be as good looking as these. The ground tip would be eaten away way more.
