We had a guy like Eric when I lived in OC California. He was a foreign car genius. We had a Volvo and if there was a problem, he'd have it fixed the first time. I remember he rebuilt his Dad's 66 Jaguar XKE convertible. Frame off restoration, built his own wire harness, perfect engine rebuild. Car looked like it came off the showroom floor. Gave it back to his Dad for his birthday.

Mr O's concientiousness and attention to detail is unreal. Tip on plastics door and other tabs for my fellow amateurs out there without Eric O's encyclopedic knowledge of disassembly techniques....get yerselves a basic plastic welder....essentially a soldering iron with wide tip....and some stainless steel mesh fabric. When you snap anything plastic....and you will...put all the broken bits back into position and then melt the wire mesh into the plastic across the breaks. The repaired part is stronger than the original. Never fails.

You would make an EXCELLENT auto shop teacher, Mr. O!

There is nothing worse than taking off a plastic panel thinking those snap noises are the connectors releasing and it’s actually the panel breaking around them.

Another great demonstration of patience. I've shed lots of skin and blood to those damn metal clips.

Experience & maintenance procedures are so important to prevent damage to plastic panels...especially experience. I still cringe every time I pop plastic door/interior panels and instrument panels. Sometimes the noise coming apart makes it sound expensive & a relief when it isn't. Nice diagnosis & repair and the connector info is valuable. You have made a great reputation for yourself and independent auto repair shops. Makes me proud to know you and someday we will meet whenever I come to NY to visit family. I'm semi-retired but it is so nice to see other independent owners give the auto repair industry a good name for quality work and diagnosing thoroughly...thanks!

Thanks Bob 👍🏼

Very interesting diagnosis and repair videos on the air bag light - thank you for sharing them. I checked the service data for my vehicle since it uses the same sensors in the doors and discovered a couple of things that I thought I would share. There is a notation in the service data on my vehicle that states: "NOTE: The signal circuit is shared at the K36 Inflatable Restraint Sensing and Diagnostic Module between the B63LF Side Impact Sensor - Left Front and the B63RR Side Impact Sensor - Right Rear (OTC 80085 and DTC 80088). Therefore a short to ground or short to voltage in either of these signal circuits can set a DTC for both circuits, and an open in either circuit should only set its corresponding DTC." This probably explains why the two sensor codes set when the sensor connector was shorted to ground since the circuits appear to be shared with the SRS module. The door sensors respond to a sudden change in air pressure inside the door cavity to activate the sensor rather than vehicle motion. The SRS module uses the information along with data from other sensors to determine things like if the vehicle is running, parked, occupied, in motion, etc. to determine whether a specific air bag should be deployed or not. From reading between the lines in the service data the SRS module checks with each sensor at start up until shut down various times per second to see if it can communicate with each sensor - probably the sensor has some sort of internal resistance reading across the two terminals. As long as the SRS can detect that resistance level is present it is happy but if the resistance value remains open or is shorted for a given time interval (more than 5 milliseconds is what I read) then the SRS will set a code for one or more sensors depending on the conditions it sees. If the ohm value of the sensor was known I would assume a variable resistor of a similar value could be connected in place of the sensor to test the integrity of the wiring and SRS module but that is only a guess. As someone else stated one too many door slams may be what caused the sensors to fail or perhaps built in GM obsolescence (God's Mystery) - it does seem strange they would both fail at the same time.

your tip at the end is incredibly important mr o not only do you not want to go blow up any air bags but i remember fixing a truck that an employee smoked the models in by cutting and splicing the under hood fuse box out on a 2011 f250 an it messed up everything the entire sub harness had to be replaced along with the bcm and a complete reprogramming of the truck as its data was badly corrupted from repeated bad diagnoses prior to coming to me its its configuration was so bad it thought it was a dually an had a completely different transmission so it was shifting strange an often not at all plus it’s security system wasn’t configured right so it thought it was being stolen all the time inside courtesy lights flashing as you’re driving. So annoying. a real mess the sad thing is it damaged the transmission so i don’t shift well if you’re hard on it when it’s cold but if you warm it up, it’s fine now and fixed. The boss is waiting for it to fail to rebuild it. What a mess.

Terrible.

Please do an autopsy on one of the bad sensors. I am very curious as to why it failed. Thanks.

You have a thing I've seen you do a lot for a long time, you check how tight a connection holds together. This time that check was needed to fix the problem, ignore it and you're still in trouble with this problem. I worked on my own cars for years, never thought to do this check. It might have come in handy. Experience is why you're so good. Pay attention to detail, analyze the problem, recall past issues, all plays into a mechanic who never seems to be stuck. A real gem of a tech. Great stuff.

I wish you could start a automotive diagnostic training of some sort. The auto repair industry is IN DIRE NEED OF TECHNICALLY SOUND diagnosticians...... Great work as always Eric. Aloha and Mahaloz from Maui, Hawaii.

I like that T-handle wrench, very handy. Jeez Louise, it took you longer to get to the sensors than it did to diagnose and replace them. Love those kinds of designs. Maybe water got into the sensors and they failed one after the other in short order? I think they make that plastic out of wasa crisp bread. Land Rover uses the same formula. Connector Experts. I will have to remember them, Working on old Land Rovers getting connectors can be a trial. Instructions for installing crimped connectors: 1. Connect the wires securely together 2. slide the connector over the wire connection 3. crimp securely using the proper crimping tool 4. But first slide on the heat shrink tubing.

Some type of surge may have caused them to both go bad, low to high voltage, badly regulated current, or worse lightning strike. around or near or on the vehicle while it was parked somewhere.I parked my Chevy truck in downtown Atlanta one day while working, had a very bad storm Lightning hail high winds came out to start my truck at the end of the day, and nothing and I kept smelling something that was burned. Then another guy in the lot noticed a burned spot with a cut right through the steel. Just remove the mirror on the passenger side door the computer had to be replaced to get the vehicle running the smell was determined that it was the smell of ozone. I kept saying something burning, but it was ozone odor.

As a gm tech for 6 years, that is the way I reinstall those doors. I usually use a set of needle nose pliers or plastic clip tool to depress both sides of the metal clip to take them out. Also had a 16 Sierra 1500 after an accident come from a body shop with new airbags and SDM wanting it programmed. Could not program it due to codes in the system. Read codes and had some from both front side impact sensors and seat belt anchor pretensioners. Pretensioners were deployed, so they needed replacement anyway, but just like you, there was no indication that the impact sensors were bad except for the code. Replacement fixed all codes and programmed vehicle.

@mbray10

Do SDM or SRS modules still lock out a crash wipe and program after a crash flag thus making it only possible to erase the codes by replacing the module / or get a company to manually erase the chip? Id assume so incase evidence needs to stay on the unit without any kind of tampering

I know this was a simple fix for you Eric, but before these vids I had assumed that working on airbag wiring was about as risky as bomb disposal! Now I have the confidence to go "ripping and tearin" with the airbag right next to my ear.. So thankyou..:)

Great job catching that pin drag.

I was noticing how clean everything under the door panels and inside those doors were. No dust, no dirt, everthing clean and shiny. Not like the cars Eric usually finds himself in the middle of.

I understand there are at least 2 types of sensors, the off/on type and the type that measures sudden changes in acceleration \ deceleration. I wonder if either can be damaged with a deer collision? Not a hard fail, but never right again kind of thing leading to a early failure. While watching the video and thinking, here is what I came up with... - These parts are prone to failure? - the deer collision mentioned in the video set these up for a an early death? - someone was in there and TESTED them to death? - I'm never right, so its something else! Love your approach and the time you take with the hardware - truly a lost art today.

awesome job.... like it. trying to maintain the integrity of ones auto today is can be most difficulty at times. god job boss. The Lord Bless you and yours.

Eric I forgot to mention in part 1 that if you found Tape(Masking) covered in Paint, Someone has definitely been in there. Another way to tell is, if inside the Door(especially underneath) is totally Painted/Clearcoat etc(no overspray/lighter parts), that's another way to tell. They're usually pretty light on/crappy under there (unless it's a Euro). While in the "Body Shop"(as you guys call it) we try to make it look like no one's ever been there as much as possible, stuff still does happen! I had a bit of a chuckle(expecting an on cam Scanner Danner moment) when you put the blow Torch next to the Battery, as several years ago one of my Workers was Grinding next to a Battery(cut off wheel doing a Skirt & Rad Support Panel) guess what happened?! Funny now, but not back then let me tell you! 😂

Happy to report GM Door Trim Engineering went away from those metal spring clips. At least they did on my 2022 GMC Yukon XL. New design has a channel in the lower sash which a lip on the door trim drops into and that holds the door panel in place at the top edge ILO the spring clips. Some engineer saved GM money (no spring clips) and made it easier to service! Give that guy a raise! Oh and BTW - the reason I had door trim off a 1 year old SUV is because my kids left it open and we had a 15min monsoon pass over in August. I wanted to take it off and make sure I got everything dried out.

It's nice to be able to get connectors in the US. I was looking for one for my Jag a few months ago, but Jaguar don't supply them separately and the company that make them, don't supply to the public, so I ended up buying a secondhand part with the connector attached. I couldn't see anyone in the UK supplying them.

2017 Buick Envision that's been driven it's whole life in dirt and salt? I'd wager that the problem with that connector was "environmentally" compromised too. Another great save by an everyday athlete. Thanks for the vid Mr. O!

Curious as to why both side airbag sensors failed at the same time. One thought is that the really small prongs in the connectors do not work when they are even slightly oxidized/dirty. Next time, it may be interesting to try and spray the electrical prongs within the connector with electrical connector cleaner and see if that solves the problem. That is the way it works on my Jeep Grand Cherokee - about every three years after year 12.

You should do a "short" on the door panel tips- those things are very helpful for beginners (my cousin just busted a few of those plastics on his car)

TESA has been used in the US for at least 20 years. Multiple types, including some that you CANNOT just tear. It has to be cut. GREAT tape.

Interesting that air bags went off. The newer cars airbag module has quite a bit of guard logic that would prevent this from occurring. The car wasn't moving so the air bags going off seems like a extremely unlikely event. I qualified air bag controller chips for the Japanese and Ford automotive and testing the chips was a nightmare because of the guard logic. Remember the movie Iron Eagle where he was using the guns on the ground? Yea, thats impossible too with weight on wheels.... aircraft munitions will not go off with weight on wheels.... tons of logic control there as well.......

A post-mortem on a bad sensor might have been fun... these are probably piezos... just a microphone, bascially... and moisture can affect them I've heard.

AAA The Power You Can Trust!

I drove a 91 mustang for years with the air bag light on. No harm no foul. Yes I knew it was on didnt have money to find the issue.

I had the exact issue (with the metal clips for the window squeegee/felt wiper) with my 2018 Sierra 1500 when I swapped out my mirrors for trailer mirrors. What a PISSER! I agree, Eric. Dumbest idea! Had me shaking my head trying to understand the logic behind the design.

It makes me wonder… if the car was at a dealer, and they tried to diagnose the issue, could they have used something that shorted out those door sensors? Or the possibility of slamming the doors shut just a few too many times?

one of two possibilities you mentioned black mold in the one door!!! he may wash it a lot!!! or its keep in a unheated garage with a lot of moisture and finally lighting hit by his vehicle!!!!!😀

My guess is the common rail of a zone supplying the ref voltage is monitored as well as the airbag return circuit, so the return circuit will see either voltage in a spec or nothing as well if the ref voltage is shorted to ground it would see the ref is 0v causing both airbag return circuits to receive 0v

Probably using front and rear left and right alternations lets it be a bit more redundant and reliable with knowing its a false trip (wiring fault) or a real collision on a certain side

The probability that this occurred by chance approaches zero with the number of sensors involved.

Hi Eric. Maybe the censors susceptible to the heavy hitters door bangers .

Agree TESA tapes are very good.

I suspect that the front left sensor issue made the other sensors misread similar to the way shorting the sensor made others read wrong!
