GM Chevy Truck: Airbag Warning Light B0044 -Part 1 

I spent 37 years repairing electronics and I must say you're very good at what you do. Great troubleshooting technique!

Ivan, your use of electronics in this video is very impressive, and I found the info put forth very helpful and very educational. Thank you, my friend, for posting.

Another great diagnostic channel. Found your channel following South Main Auto Repair, wasn't disappointed. Brilliant video!

As Eric would say, "There's your problem right there!" as you point to the bow tie on the front grill. 😁

6 people are bad mechanics! Good Job Ivan! Great Video as always.

Ivan is the man ,don't worry he will fix it

great video .great work!big thumb up!

AFTER ALL THE VERY USEFUL INFORMATION :) "YOU FOUND", THE ISSUE, IT STEMMED FROM THE CONNECTOR IN THE REAR OF THE VEHICLE AT THE MODULE... MAYBE A LITTLE DIELECTRIC GREASE WOULD HELP TO KEEP THE CONNECTIONS CLEAN AND DRY... MY PROFESSION IS VEHICULAR ELECTRIC, YOUR TECHNIQUE IS VERY SIMILAR TO MINE... EXCELLENT JOB!!!!

GREAT information! thanks for that site. I saved that!

I didnt realize you have a channel! This is great!!! Remember the DEBOK is a registered trademark- I normally get significant royalties for its use, but I'll give you a pass for doing a great job! Seriously- great job bro. This one reminds me of one of my favorite viewer comments: "You know you're a 2%er when you get frustrated at an intermittent problem fixing itself instead of being happy about it like everyone else does".

Hi Ivan - hey nobody in Avoca NY told us you were making vids :) nice vid look forward to more.

Nice work! Hope my issue is the same fix!

Fixed my Duramax today. 1’airbag sensor on middle of radiator bracket. Not 2 like the 1500 models. B0103 code. Both batteries died also today. Bought new interstate brand. so replaced sensor while batteries were out of truck. Truck runs better with new batteries and lights are brighter and truck has more power.

Thanks Currently diagnosing exactly the same issue on same city fleet truck Previous technician threw a bunch of parts at it, 6mos ago Naturally it didn’t fix it Honestly thinking SRS module

Nice vídeos 👍🏻

It's a clock spring ! Not a coil lol you make great videos man

I have a 2013 Silverado that shows an intermittent airbag light/service airbag. I have seen problems with connectors on the front of this truck. Pulling the connector apart, making sure it is clean and then using silicone grease to repel any moisture may correct the problem and would be the first thing I would try before easter-egging parts. This should also prevent moisture from being an ongoing issue.

In many cases the airbag light comes on because of the connection under the seat. I cleaned mine and never another problem.

Ivan I fix a lot of them by removing the shorting bar the shorting bar is for shipping so they don’t deploy

Im having the same issue. 2005 silverado airbag light stays on. I need a vin inspection done. They wont do it with that light on. B0044- B0101 codes came up. Took it to 2 different mechanics. They had the truck for. Month. Came back supposedly fixed. Was working until i was going to take it to get inspected. Then bam the light stayed on. And this is how i came across u channel lol looking for answers and fixes

great video Ivan..where do you get your multimeter leads and backprobing accessories?

Great job explaining everything but what was your over all diagnosis to fix the problem

I know you did resistance checks but I could not asertain wether those values where cuasing the code or the natuaral state of connectors and wiring

I should have looked at comments earlier. Great video, but unfortunately when I went to BBB industries, I found this message-"BBB no longer offers TSBs and wiring diagrams. We apologize for the inconvenience. " I'm looking for another source to continue the repairs

what version is verus snap on -i want one?you are my inspiration!

Nice work Ivan and it does look like you have a pin to pin issue inside the connector since it went away. Keep up the good work.

Gm has a tsb about terminal fretting which may be the issue here. Don't ya hate when your trying to diagnose something and the problem disappears!

I know this is an old video. But I heard you should never test airbag squibs with an ohm meter. The dvom uses a low voltage to test for ohms and the current being passed through the squib can be enough to detonate the air bag. A safer test is to put four 10 ohm resistors in parallel (just an easy way to make 2.5 ohms), jump the pins on the module side, and the code should go away. Then you can just remove the air bag from the steering wheel and put the same four 10 ohm resistors into the wires, plug the connector back in, and if the code comes back you know there is an open between the connector and the airbag (99.9% clockspring). If the code is still gone, you know the squib is open circuited.

I've never had to do an airbag diagnosis. I was under the impression doing resistance tests and in fact even voltage tests might cause deployment. What is the actual combination of events that would cause deployment?

Hello. I have a 2008 GMC Savana 2500 6.0. It has a code B0091 front end sensor 3. Do you know the physical location of this sensor? Thanks.

Thanks brother for showing us your knowledge, hey I have a 2017 Ford F-350 6.7 and I have this code U0557 and do you have any idea what can be, or what I have to check first, thanks again for your wonderful videos,

Hi & where can I buy an scanner like that

Ivan I forgot to tell you I work with a air bag place out of Dallas and they told me the shorting bars get weak and they tell me to remove them I remove a lot of them I always thought you needed them and they tell me to remove it

My 2006 GMC Sierra has the same problem . Service airbag for 4 years now 👍🇨🇦

I have a 99 chevrolet blazer airbag light on I've tested through airbag system getting 2.5ohms on airbag with shorting bar disengaged reading volts from sdm is 9volts with airbag unplugged code was passenger loop open I show no circuit problems at connectors behind glove box

09090 make sure stop at front office I miss you in love u

What is the link to get wire diagrams?

Ivan, I have an 04 Escalade I believe has a similar issue, unfortunately I do not have a scope but I measured the voltage at the connector for the left front impact sensor, grey wire (high side) is 8v or so (not accurate I know) and the yellow only shows .04v. Only code is for sensor performance B0100, i had tried swapping the sensor with another used one. Resistance is only .1 ohms from front connector to c204 behind the kick, and voltage is the same with c204 unplugged. I used wd40 on the connector to the srs module under the seat, I'll be ordering some deoxit soon! My question is do the impact sensors see a similar signal as the pins you checked in these videos? (Didn't think to check the pins to the right sensor yet🤷‍♀️) thank you for the awesome videos!

so were was the problem under the seat.

I wish you were in NYC. I got B0081_00 on my Cadillac escalade 2010 and it appeared one day after I left vehicle with lights on and battery died. After I changed battery and installed terminals I got a code. I don't know what should I do.

Hi Do have any idea how to fix the issue with 05 Yukon traction control kicking in all the time for no reason, and also activating abs , Causing the car to not move in middle of an intersection

I have a 2004 subaru forester that had been backed into hard enough to deploy both air bags, I replace the bags and the light is still on, do you think something other than the bags could have been damaged, I also had to replace the connector on the steering wheel bag wire,

Hi Ivan, this video and the part 2 is amazing, it's just what I was looking for to have an idea about it. I have a Chevy TrailBlazer 2007, 5.3L and I have these codes B0042 and B0022. Do you have any idea what is happening.Apparently is a circuit issue. I used a contact cleaner and nothing, and the mechanic put a resistance to prove and nothing.If you have any advise I will really appreciate your help my dear friend.

I removed my steering wheel airbag to access the wiring for my SWC I don’t think it shows the airbag light but i do have the. Service air bag on the screen. I had the battery disconnected about a day before removing and the same when installing. Never been deployed and plugged in. Same order I took out with 2 the two connects. Could it be a fuse I blew causing it to trigger if anyone has experience. It’s a 2006 Sierra.

I have a 2007 Chevy Cargo Van. No loos wires or connections. The airbag blinks and then it stays on. The drivers seat recognizes me sitting in it with the seat belt unbuckled . The passengers seat does not recognize me. I can sit in passenger seat and seat belt light will not come on. I pulled the seat out and unplugged it and same problem, airbag light on and no seat belt light. I pulled back the vinyl seat covers and see a module with a ribbon cable going to a pad. Could the seat module/ribbon cable pad be open??

BBB Industry no longer has wiring diagrams. Sad update.

You MF Rock Fuck all the negative comments 👍

Man. BBB Industries no longer offers TSBs and wiring diagrams 😢

OK Ivan this one is bugging me so basically I have seen diagnostic stradegys from manufacurer saying unplug and plug it back in was this a situation where the circuit is so sensitive the line just creates a problem for certain circuits like the air bag circuit basically what you did to fix it was go down and mess with connectors unplug and plug them back in the regain proper continuity where you should have had proper continuity I stand still inmtimitaded by air bag circuits DAM IT

My 03 silverado 1500 is doing the exact thing same codes popping up and disappearing

sorry no quick message radio matched description 93 stolen Chevy on 11/24/2020 no Triton or 412 on any swaps wipde

Smart ass comment # 14574 Ck gas cap, opened gas door yep gas caps there. Ck engine light Opened hood yep engines there. Ck airbag. Looked in passanger set yep wife's there.

My light is on right now

I thought the air bag system was not serviceable I got that problem on my 08 impala reset the computer half a dozen times and I do not know what to do dealer can not find the problem I think my car has a serious electrical problem can you help

that truck has the shitty plastic Pro-Tec bed on it. its a composite plastic. if it breaks you wont be able to get a new one as they are discontinued

I hav no codes on scan tool but airbag light is on. Any fix?

bbb no longer offers wiring diagrams

Been 7 years. Did you ever figure it out? I had the same codes but had nothing to do with wiring or driver side. Message back if you want to know what problem I found and, although haven't fixed, but know what the issue is.

Save all the hastle.....if you ever see a service airbag light on a chevy its the sensor dude LMAO. :P

So what did you really do turn the light off, you lost me with all the volts stuff

BBBind no longer offers TSBs and wiring diagrams. Just in case anyone sees this video

bbb industries is now gone. any alternative

When electronics where Japanese made I only ever replaced them if customers wanted upgrades or broke it, then the chinese landfill started to swamp everything and nothing worked right and failed in less than a year. Decades of rubbish and getting to the norm of junk out of box now.

my service air bags is on & on my truck 04 Silverado what is the problem

Surprised it dont say service 4wd

Don’t waste your time replace the sensor underneath the truck. Wow really all that bs for no answer wow.

Just a small critique next time blur out the legitimate vin number

Great fucking video THANK YOU
