There shouldnt be an airbag light on. The only airbag light should be on the rear view mirror, saying if the passenger airbag is on/off.

There are too many connections, modules or sensors to go bad. You need to get a tech 11 or scanner that will read B codes and that will tell you where the problem is. A regular OBD 11 scanner will not read B codes.

Probably a bad connection and/or water intrusion at the front g-force sensor.

 

I just replaced a front sensor on my wifes "05 Suburban. I forgot the code, but it was defined as "Front Airbag Sensor 2 blah blah". I ordered the part from GM Parts Direct totalling $86. This code refered to the passenger side sensor. When you look underneath the truck look for the tell tale yellow plug. The sensor is about 1.5" square with one bolt. Not hard to do if this is your problem.

Yellow connectors usually == Airbag system..... I can not think of another place a yellow connector is used. But you need a high end scanner plugged up and the codes retrieved (Genisys, Pegisys, Tech II, etc, etc)....

 

Last airbag system I had to work on it was a S-10 with power seats, the track had pinched the wire and cut it in two.

 

Don't forget when working with an airbag system remove the battery cables and wait 30 minutes for the system to discharge, before removing connectors or airbags. The system is live with out the key on and live for period of time with out the battery cables connected (aka it can cause the airbag to deploy with out the battery hooked up).

There are several yellow connectors in the system. they are under the seat, under the dash, behind the kick panel, and in the front of the vehicle. Any one of them can go bad. There are modules under the seat that can go bad. there are two front sensors that can go bad.

 

When I am working on the air-bag system I don't disconnect the battery any more..I follow the procedure in the GM factory service manual.

 

deployment power is only available for up to one minute after power is is disconnected.

 

Take out the SIR fuse, then disconnect the connector position (CPA) assurance , thats the yellow connector that powers which ever restraint system you are working on. There will be no power to that system and it cannot deploy. Yes I have used this procedure a bunch with no issues. If you are scared, disconnect the battery.

 

I used this procedure Monday when I added dic to my truck and had to remove the drivers side airbag.

 

This is for replacing the front sensor...

      Transmission Temperature Hitting 220s

      By newdude · Posted

      It is working as designed.  NHT and non NHT trucks have the same exact transmission cooling setup.  NHT just gets a larger radiator.     The transmission cooler loop on these is as follows.     -Transmission out goes into an oil to water heat exchanger (item #1 in the first illustration below).  This exchanger has engine coolant opposite the transmission fluid and uses engine coolant to warm and then regulate the transmission fluid temperature when its in the operating window.   - From the cooler it goes to a thermal bypass valve (item #11 in the 2nd illustration below).  If the ATF has not reached the temp to open the bypass (194F), it loops back.   - When it reaches 194F, the thermostat opens and ATF then flows out to the oil to air auxiliary cooler (item #17 in the 2nd illustration) at the front of the truck.  From there it goes back to the transmission.     Your only fix would be to swap for the PPE thermal bypass delete block which will open the loop to the aux cooler all the time.  It will STILL run warm, probably 170-200F, but that's as low as you'll get it as its still flowing through the oil to water exchanger.

      Most say the oil temperature needs to above the boiling point of water to rid it of moisture and long enough to dry it. Many think that is about a hour at 212 F or more. Those people have never line dried cloths in a Midwest winter. Leave a pan of water sitting on the counter and eventually it all evaporates. So heat drives the time it takes. Water in oil under 175 F, the Nitration initiation temperature, is a minimum then for temperature and samples I've done that use Karl Fisher method say about a hour (in a healthy well tuned motor) over 175 F will dry it to under 800 ppm. Low enough to not be much of a factor. Motors with weak rings will take longer and the colder the air temperature the longer it takes.   On a cold motor there is also the condensation temperature. Blowby gases that contain moisture are subject to that cold cylinder wall, like sweat on a glass of ice tea. But also subject to the Law of Partial Pressures. Wear studies by GM and the DOD  indicate wear is a real issue below 85 F and a concern to 140 F but doesn't become a minimal factor until about 160 F. You know this intuitively when you see water vapor exit the exhaust pipe until the system gets above the dew point. It isn't magic, it's physics and it fascinates me. I know you didn't ask but....I over share sometimes. 😉    You keep the Camaro's high and tight.

      Move further away.   Benefit of living out - none of our cars get short cycled, plenty of warm up time.   Curious how much time/temperature it takes to drive moisture/condensation out of the engine?

      Transmission Temperature Hitting 220s

      Switch a a 100% synthetic trans fluid, Amsoil works for me.

      Transmission Temperature Hitting 220s

      By DustMcGrath · Posted

      First of all sorry, I know there are a ton of transmission temperature threads...   My truck is a 2025 LZ0 High (10l89 10-speed) High Country with NHT max trailering package. The NHT package is supposed to have "enhanced cooling."   Normally the trans temp sits around 200. It seems like with any real stress it quickly jumps into the 220s (for example climbing a grade unloaded at lower speeds). I haven't towed much with this truck, but I'm concerned if it gets this hot unloaded.    I've tried a few different things to keep the temps down (tow/haul mode, sport mode, low range when that makes sense) and nothing seems to affect it.    I'm curious if others are the same behavior or if anyone has found techniques to keep the temps down. It seems like it just can't handle reduced airflow at lower speeds, even with relatively light loading.    Thanks!
