In this video I have a look at a 2005 Buick LeSabre that came in with the Air Bag light glowing. Service data and flow charts would have you hours deep into making the call on the faulty part. I think we can read the theory and operation and get the the problem a little quicker. -Enjoy!

    Thanks for the volt meter comment. I have the same issue with my Buick but I haven’t determined if I have been molested by a squirrel or if the sensor is bad. The noise under the dash is probably an hvac actuator trying to get going. I truly enjoy your videos.

  2. Avataaar/Circle Created with python_avatars Mike Castellon says:

    Lee say bray?

  3. Avataaar/Circle Created with python_avatars jeremy32100 says:

    What kind of scan toll is that and where can I buy one thanks

  4. Avataaar/Circle Created with python_avatars george536 says:

    Does the service information (diagrams, code criteria, flowcharts) come with the scan tool when purchasing? Or is it a purchase plus subscription?

  5. Avataaar/Circle Created with python_avatars moe Carter says:

    Also there are no codes available.

  7. Avataaar/Circle Created with python_avatars Joseph Wildrick says:

  8. Avataaar/Circle Created with python_avatars Dangerous Amoeba says:

    My 1997 corrola airbag light came on for a few minutes. I was very confused and afraid because the car has no airbags…

  9. Avataaar/Circle Created with python_avatars Donald Swink says:

    Eric O, I know it’s your Youtube channel but you should do a special one called, A day with Mrs.O, what a normal day is like for her. Just a thought.

  10. Avataaar/Circle Created with python_avatars Yaman Sy says:

    Nice

  11. Avataaar/Circle Created with python_avatars Jesse W says:

    You got rid of the red and yellow thumbnail text? How dare you change! I'm outta here.

    Nah it's cool, I like the new look. Keep up the awesome diagnostic content.

  12. Avataaar/Circle Created with python_avatars sonastainbrook says:

    My 2005 Buick Lasabre is in the shop right now and the mechanic called me and said the front sensor is bad and it is 200.00 for the part. I'm looking for one online to see if I can get it for less. So far no good. Guesss I;m out 200 bucks! Thank you.

  13. Avataaar/Circle Created with python_avatars metalcreatures says:

    Good lord what is the background noise

  14. Avataaar/Circle Created with python_avatars Steve Fleck says:

    Great video Mr O. You never cease to amaze!

  15. Avataaar/Circle Created with python_avatars Billy Horton says:

    Nice job. Realize it was about the air bag sensor, but you went right by the strange noise behind the dash. Maybe you and the owner could find out what exactly is going on.

  16. Avataaar/Circle Created with python_avatars RJB says:

    Good channel. I subscribed a few days ago. Very down to earth and a good variety of repairs and vehicles. 👍

  17. Avataaar/Circle Created with python_avatars a625 c625 says:

    is upstate still stuck in the 70's?

  18. Avataaar/Circle Created with python_avatars geosutube says:

    Local shop did auto body repair, airbag lite was on when I drove it off the lot, service manager did not mention the problem, said he forgot to, and the mechanic was not in for two more days.. Not trusting them, I asked a friend/mechanic to check it out. FIrst thing he asked, “Did it read out any codes at all or was it just lit up?” No codes. Then I discovered this video. I’m taking it in to mechanic tomorrow. Someone I can trust. I will admit that the body shop did great work. Not so sure about their mechanics, however. Also, the tire inflation monitor also lit, not red, no codes.

  19. Avataaar/Circle Created with python_avatars Miguel Fatman says:

    Noise in the dash, easy to determine that one, it's the emergency hamster driven battery charger, its wheel needs a spot of lube

  20. Avataaar/Circle Created with python_avatars Antonio Claudio Michael says:

    Good simple diag and repair

  21. Avataaar/Circle Created with python_avatars Antonio Claudio Michael says:

    Great video Eric O

  22. Avataaar/Circle Created with python_avatars BUZ1952 Z says:

    Slick and there's nothing better then the smell of fresh asphalt in the morning.

  23. Avataaar/Circle Created with python_avatars WorldRenownedCFE 🎤 says:

    so how much did you charge the customer for this repair?

  24. Avataaar/Circle Created with python_avatars Staggerweed Productions says:

  26. Avataaar/Circle Created with python_avatars John Frese says:

    have a question by any chance do you know where the headlight and foglight relays are on a 07 monte carlo / impala model because there not in the usual spot under the hood location trying to find out why my day time running lights not working as well as my fog lights want to check out the relays first. there not in the usual spot under the hood much help will be apreceated

  27. Avataaar/Circle Created with python_avatars GERMAN JESUS says:

    For some reason every general motor products I’ve worked on in the past 10 years all had mice damage. There like cheese to them can’t figure out why.

  28. Avataaar/Circle Created with python_avatars Jessica Thornley says:

    Mmmm… The bearded man can check my oil anytime 😍

  29. Avataaar/Circle Created with python_avatars Brian Austin says:

    The Buick's dash is sending a Morse Code message…

  30. Avataaar/Circle Created with python_avatars splice247 says:

    Service data said it checks 3 times before setting a code, it did not say it would stop checking after that

  31. Avataaar/Circle Created with python_avatars Smitty Smithsonite says:

    WHAT?? They're paving already??? Geesh … here in MA, when they start a road project, it's a minimum of a year before anything gets done, most of the time longer! 😡

    Good to know the SDM sends that signal out. I didn't know that. The one time I changed front sensors in a '07 Sierra, the problem was obvious – no testing needed. The things were swollen and blown out in several spots, with green crust oozing from each crack! Fantastic engineering, straight from Singapore. GM, hitting 'em outta the park, as usual! 😂

    You and the fam-jam have a great Independence Day! I need to go look for fuse for my mini-cannon. 😉

  32. Avataaar/Circle Created with python_avatars Andrew W MacFadyen says:

    Changed a few impact sensors, usually side impact sensors due to water ingress. The difference between a good and bad sensor at key on self-test really shows up on the oscilloscope a good sensors has a very distinctive pattern

  33. Avataaar/Circle Created with python_avatars Radio Rescue says:

    Ive replaced a few of these on GM's they seem to be a common issue on northern cars. The sensor gets corroded at the metal sleeve where the mounting screw is. What's real fun is when that mounting screw breaks off in the rad support. On Chevy trucks you have to remove the radiator and condenser to access the broken carnage. Putting it nicely as Eric says it's a real pisser of a job.

  34. Avataaar/Circle Created with python_avatars Tim Wrenn says:

    kool! Dr. Eric! you da man! I'm ascared of airbags! thank you for enlighting me!

  35. Avataaar/Circle Created with python_avatars Kingbolen Auto Scanner Center says:

    Nice Air Bag diagnosis video, Eric have almost nice tool Snap-on Autel Launch BOSCH.

  36. Avataaar/Circle Created with python_avatars tim m says:

    Yes I could do it….. If I had a 3000$$ dollar scan tool. just messing around. Good vid

  37. Avataaar/Circle Created with python_avatars Richard Gill says:

    👍👍

  38. Avataaar/Circle Created with python_avatars jon smith says:

    I just had this problem and I couldn't find any information about it anywhere including my service manual so I had a garage do it for 450.00. Could a guy with no electrical testers do this job. Thanks

  39. Avataaar/Circle Created with python_avatars shauns auto repairs says:

    Good stuff.
    Thought you were going to do a bypass with a resistor if that would work in this case..thanks for sharing

  40. Avataaar/Circle Created with python_avatars les best says:

    Speedo goes to 140…….mph or kph, no dual scale and didn't see label.

  41. Avataaar/Circle Created with python_avatars spin1275gt says:

    Would have been interesting to see what the signal looks like with the new sensor plugged in. It should be abel to send some kind of signal back to the SDM

  42. Avataaar/Circle Created with python_avatars jake ounce says:

    You need to do a video on, "how to deploy an Airbag" as part of the 4th festivities !!! BOOM

  43. Avataaar/Circle Created with python_avatars Ron S says:

    But can she do it?

  44. Avataaar/Circle Created with python_avatars Ron S says:

    That's what I wanted to do also. Front probe it GINGERLY!! 😱😝

  45. Avataaar/Circle Created with python_avatars wurly one says:

    Not a comment about the fault/repair I'm afraid… How comes there's such a big gap between when they rip up the old road tarmac and when they replace it? (was it a month?!) They do it pretty much same day in the UK!

  46. Avataaar/Circle Created with python_avatars Kevin Johnson says:

    I wonder how many actually figure out the threads are lefties.. Would drive me a bit nuts if not specifically stated some place. Thanks for sharing.
