06 Silverado ext cab.. I spent 3 hours looking for why I had an airbag light on. Code was indicating passenger side. Finally decided to track each wire under the passenger seat. Sure enough, one wire broken even though the insulation was ok. Apparently, sliding the seat forward and backward caused stress on a wiring harness and the wire broke. Saudering a new wire in while the seat was in place was not fun but not difficult. Just passing along in case you move your seats a lot.
I should have noted that I tried swapping the sensors in the front to see if the code switched to driver side. These sensors were the first thing I went after but of course it wasn't those in my case.
Thanks for the safety tip when you demonstrated the ignition on before reconnecting the battery! Looking like I'm gonna have to replace my sensor(s)! Thanks for the video! Keep wrenching!
@4:35 I saw a technician NOT disconnect the battery while performing an ORC Recall. He made the mistake of unbolting and then turned over the ORC on a Chrysler product. Instantly several of the air bags deployed. Vehicle thought it had just been in a rollover accident. New controller, new airbags, new headliner, and several weeks passed before the owner got it back. @ 5:25. Engineers that never raised a hood. I hear you often say “Don’t go all bananas on it.” I often say “Finesse is your friend.” Similar concept, same intent.
I have replaced 3 impact sensors in the last five years of owning a 2008 sierra. The last two I bought 2 months ago cost twice as much as the 1st I bought 5 years ago. I added some silicone between the sensor on frame to keep water out, and a bit of antisieze in the bolt thread. Of course the first and obviously cracked sensor I replaced did not clear the airbag light. I replaced the other and all good now. Almost $300 for two new sensors. Rockauto was out of stock, but a 20% coupon at autozone helped out greatly.
Not all vehicles reset the air bag light my GM-H Australian one had to be reset with a scanner after I changed the drviers seat (it had an airbag on side of the seat.
Hey, Ken - just an FYI. it's Generally NOT considered a recommended practice to disconnect OR Reconnect the 12 Volt + Battery Power OR - Ground cables while the Ignition Switch in the On Postion. This is just plain Asking for Trouble - and nobody needs any extra Automotive Electrical Trouble ! Plenty of that to go around already ! Just Sayin' ...
Didn’t like that either. Saw the large spark when reconnecting the battery to a preloaded electrical circuit. What’s the advantage over hooking the battery up first then reaching in to energize the run circuits?
@@j.b.9895 The advantage is that you prevent this HUGE Voltage Spike that happens when not only EVERYTHING in the Vehicle is Powering up at the same time, even BEFORE any of the Electrical Capacitors charge back up that are designed to PREVENT these kinds of Large Voltage & Amperage (Current) Spikes. too much wear & tear with this type of super aggressive and totally unecessary power up !
Thanks for showing this Kenny, at least I know what to look for. Only question I have is if that didn't work, would that mean you need a new airbag? Also, the word on the sensor was Singapore not signature, that doesn't surprise me. They pour the engine blocks in Mexico, electronics in China, and have the gall to say not to buy foreign cars. Even when you buy American, you are still buying foreign, good grief!
I priced those for my 2002 Silverado. They're $500 each! They do look different than those your truck needs. UPDATE: The prices I got were from Autozone and Rock Auto. Ebay has them from $30 and up, new and used. I would have no idea what to buy if my truck needed one of these.
I'm still trying to figure what's wrong with the SRS in my 01 Yukon? Every scanner I've used gives me different error codes? It's strange. I verify the passenger bag is still there I don't know how to check the one on the steering wheel? I know in the past people have stolen airbags and stuffed rags in there place like the Catalytic converter thefts of today 😢, Someone before I purchased it removed the instrument cluster and cut the trace to the SRS LED so it never comes on 😮 I'll solder it together when I figure it out? I might just replace all of them , it had side air bags with a sensor inside each door also.
Fix the wire going to the IC before you do anything. Also, just replacing the airbags probably won't fix the problem. It might, but I wouldn't count on it. You may want to bring the vehicle to someone that has experience working on these systems. To do a proper diagnosis, you're going to need the wiring diagrams for the SRS system. When dealing with air bags, you have the deployment system, and the reference system. Since the air bags are a major safety feature a reference system is used to alert you to a problem that would stop the airbags from deploying in the event of an accident. This is where your problem usually lies. A 5v reference is sent through the entire system. If the reference stops, or goes out of spec, your SRS light will come on, and the system will be disabled. Its a safety feature. For example, without the constant reference, if a wire is damaged while working on the vehicle, you may not know it, and if you are in an accident an airbag may not deploy. So, unless you are fixing a known issue with the system, like a recall or service bulletin, you need to check the entire system to make sure the 5v completes the entire circuit unbroken. That's why you need to fix the wire to the IC and get the wiring diagrams for the SRS. Usually, the problem is a wiring or clock spring issue. If not, you need to check the airbags themselves, and possibly the seat belts. You do this with resistors. You can buy special resistors to simulate components like airbags. To use them you unplug the wiring harness going to an airbag and insert the resistor. SRS codes are hard faults and can't be reset. The only way to get rid of it is to fix the problem, so if whatever you're trying fixes the issue, you usually know right away. Unless you have money to throw away, this is not something you want to fire the parts canon on.
Aren't the + and - always on the same side on all batteries? If so GM didn't put the terminals there the battery manufacturer did. Sure they could have made it so the terminals were forward facing so the positive would be inboard but there's less metal to hit in an accident with the battery terminals facing back towards the passenger compartment. Just an observation.

Thanks for the video Kenny I gotta change the sensors on my 2006 Avalanche and now I know how.

Kenny you are a Dam good guy. Always enjoy your videos. Trying to watch all of them .

Now they are $319.99 each!
@@akaredcrossbow unbelievable! I should have hoarded them when I had a chance.
@@timcees there must be a shortage because the cheaper ones are hard to find in stock.
@@timcees you would be making a fortune on eBay 🤣
I hope I never have to do this job but if I do, I know how. Keep the good stuff coming.
Famous last words... "Trust me!" from a mechanic.. lol
Thanks for your videos!!!
I think moe waits until you start a video and then starts pounding on something 😂
Thanks for sharing
Another informative video. 👍
Mine is on 2016 Silverado.
What size wrench do you need to replace these?
What olhms does a good one read?
I have drivers side 9.52 and passenger 9.71
Hi. Is it the same sensors on a Avalnche 2004 ?

I had these codes and I replace both sensors yet the airbag light was on and I still had the same codes.

Oh, wanted to add, common sense lead you to the common sensor, lol.
@8:42 Unless it's an 'in' joke I don't know about, that wasn't SIGNATURE, it was SINGAPORE.
MC SINGAPORE OR SIGNATURE

Manufacturers have been known to build their products to Customer specifications, but I think the batteries are made to standards, nowadays.
Generally, batteries can be handed, and the positive and negative terminals could be either way round.
Amazes me how cheap people don’t have the smarts to keep their old cars longer by avoiding rust with a cheap application of fluid film every 2 years…
Looks like someone fluid filmed the frame. 👍
