Nice, punched and chalked in the face, I remember it well. I see deer, point finger and go "DUH............" BOOM, wake up in Skyrim. I didn't even get to finish saying deer.
Yeah man, I agree, that was my first thought as well. I remember back in the late 90s at my local Chevy dealer body shop there was a framed airbag on their wall with a perfect impression of a fat woman’s face on the fabric due to the amount of makeup she was wearing at the time of impact! Always made me chuckle.
Anyone else enjoy double satisfaction in these videos by not only learning from EricO’s diagnostics methodology but also listening to Josh work in the background and trying to decipher what kind of job he’s doing based solely on sound? Just me? Thanks for the video EricO!
Nice diagnostics as usual. I did a VIN search on that car, it was totaled in a rollover. It was originally auctioned with a Pa salvage certificate. Someone "repaired" it and got a clear Pennsylvania title. Powder is from the airbag, the rust is from sitting outside with a broken windshield. All the modules under the dash probably got wet.
Googled the VIN. This car has been in and out of the auction yard a few times. Looks like it was a pretty bad rollover, someone bought it, fixed it up, put 4000 miles on it and sent it back to auction where it sold again.
Looked at the pictures myself and it looks like the accident it was in was severe enough to compromise the windshield to where the interior was exposed to the elements.
@@glenjamindle no, a full body swap is not possible with a unibodied car, and it is quite illegal; they likely repaired or replaced parts of the roof and made sure that the windshield didn’t leak; but judging on how the SIR module still had the deployment codes from the original rollover, I bet this car was doctored several times and probably doesn’t have a fully functioning SIR system.

Good show Eric. I'm an old guy now but here's what I think about vehicles, what was wrong with the older cars without all this new electronic crap, I think that electronic engine management was a true useful advancement. the rest of the stuff we don't need.
Fortunately or unfortunately, humans can’t help themselves from creating new things over and over… sometimes for better and sometimes for worse. Change is one thing that will never change!
Another excellent diagnosis, Eric! The white powder is likely talc from the airbag deployment as others have stated. Looking forward to part 2, but with a repaired module and proper fuse, I bet it will work as it should.
You mentioned something about the cost of repairing car today. When I was still in the business many years ago, I was always saying that the manufacturers were going to price themselves out of the market for repairs. It looks like this is coming true. Great video Eric. Glad someone is still out there doing these types of repairs. I can't imagine taking an issue like this to a dealership. I bet it would end up being out of sight as far as the charge.
Back in 2008 I was picking up my new car from GM dealer service when I overheard a service rep talking to a customer about an estimate to diagnose an engine problem. The initial est fee was $75 at the time. The rep was telling the customer that they suspected the camshaft was worn causing the problem BUT they needed to take apart the engine to verify that. The dealer wanted $700 dollars more to do that to provide an estimate for replacing the camshaft and the rep said if they declined the estimate at that point the car would not be put back together unless more labor was paid to do that. All for a rough idle. The customer paid $75 for the camshaft guess to be told another $700 for an estimate. I'll never go to a dealership for service again unless the car is under warranty.
@@Leon-qc7feI have had to do visuals on the camshaft lobe for a diagnosis in the past. The initial $75 ruled everything else out and got them to the suggestion. Today, could dish with a pressure transducer if you can find a person to run that test.
@mph5896 You can be pretty confident in a diag of a worn cam lobe with a trusty old compression gauge and a vacuum gauge if there are no other major symptoms.
Wonder if the hvac was leaking at some time. As for the hvac talking to the radio module, you can thank the handsfree phone connection. When a phone call is made the blower fan speed is reduced.
Is that a GM specific-behavior or standard practice? Wouldn't it make more sense to simply reposition the microphone away from the blower motor, rather than inconvenience the user with reduced HVAC on a hot/cold day?

Mr. O, I love your videos better than any other fix-it videos out there. You have a style that is respectful of all, even those who are more challenged in their abilities to fix things before you get their vehicles, and you make the effort to share your knowledge and hard-earned skills with us. Keep up the good work! The only tiny, teeny-weeny fault I found with your wiring diagram comment was around the 7:00 mark. The UQF power comes in on connector X3, pin 8, not X1 pin 1, if I understand it right. The folks who drew the wiring diagram have the power and grounds above and below each other, but they are not directly across from each other. They need to go back to school! Regardless, you still found the right wires, and I will remain subscribed to your content and watch every video. I also look forward to the next episode of this vehicle's repair so we can all tie up the loose ends. Enjoy your weekend as I'm sure it's well-deserved.
ASE certifications are specific to different aspects of vehicles. The ASE L1 certification (Advanced Engine Performance) test requires understanding many of the principles of electrical system operation and diagnosis Mr. O has mastered and shows us in his videos. Of course, knowing how to interpret a wiring diagram and knowing how to deploy various tools to make diagnoses in the real world can be two different things, which is why some "ASE-certified" mechanics are not all that and a bag of potato chips.
Another SMA piece of excellence! I would of gone for the radio module after seeing all that air bag powder and checking the VIN for accidents! Waiting on part 2.
Love the pull down technique for the network! It’s quick! I would have unplugged it and made sure I still had network activity to check circuit integrity, but that requires fiddling with those dang connectors again! Nice trick Eric.
Power was on the other connector so I would have pulled it to be sure its not an output from the radio, or could have pulled the connector with the coms on it, but a lamp to ground really proves its working at the other end.
Um pulling the network to ground, to set a code in another module to test network integrity never would have thought to do that. Going to stick that one in the old memory bank. Thanks Eric, learn something everyday.
Eric O, you are, undoubtedly, the trouble shooting and electron king! I have been watching your channel for years, and you gave me the confidence to keep my 05 Hyundai Sonata rolling down the road, here in the rust belt of the Peoples Republic of Minnesota. Money light came on last week, trouble shot it down to the engine coolant sensor, good power and ground, let's get after it!
One heck of a core charge there! I do hope you have a part 2 so we can see if it is more than a plug and play. I'm guessing there is more to it than that. I enjoy your videos.
If it is a vehicle that has been in an accident most of the modules do not like the shock of a heavy collision & most likely damaged the board or other micro chip components that is why can be repaired.Cheers Mr O.
"Sultans of Swing" in the background really brought me back to the days when i was working with my dad in the cabinet shop. I know the YT will come after ya for the copyright if it ever was prominent, but it made my night just ever so slightly in the background behind your voice during diagnosis. Good memories. Thanks dude.
A lot of good detective work in the comments. Unrelated, my wife's '22 Equinox was getting a morning OTA update a few months ago. Well, there was an issue with the connection, and the radio was bricked in the process. She was heading out of town that morning! We were able to get it replaced under warranty.
I've been listening to the sultans of swing by the dire straights every day for the last week. A new SMA video drops with none other than the sultans of swing playing in the background. Love it, this song always reminds me of road trips with my dad and brother growing up, he loved that song.
15:23 If I had to guess, I'd say that white powder is cornstarch. It's used in airbags to reduce the friction between folds of plastic bag as it inflates. Since the car had inflatable restraint codes, that would make sense.
There are a couple of clues here that are telling. 1, The fuse was replaced with a higher value. 2. Someone had the access covers off that area. If I were to guess, it appears that something happened to that module during the crash that caused the fuse to blow. Somebody tried for the 'easy fix' and just replaced the fuse with a higher value. This is NEVER a good idea. The fuse s meant to protect the circuit. Putting a higher value fuse will allow more current through the circuit that it was designed to handle. That is almost a sure fire way to destroy the device that the fuse was protecting. I have seen people do this with old valuable vintage guitar amps and totally destroy them.
Fuses protect wire not loads. If the load needs a fuse, it usually comes with it separately. If the load is not damaged, it won't pull any more current than with a smaller fuse on the wire. If the load is damaged, it might pull more current. Now we're back to protecting the wire. But if you put a larger fuse on the wire, whatever short the load has is just going to finish off the load. But the load was already damaged.
@7:00 you said UQF then went to the diagram and pointed at uqf and then went straight up and said it was on pin one. UQA was on pin 1 and uqf on pin 8.
NORDO is the way to go. Anytime I turn on the radio all I hear are commercials and blah blah blah. Did you know Casey Kasem is still on the radio with his top whatever countdowns? Who knew. He just keeps on going and going and going like Bob Ross. Is it a happy radio? Maybe that white stuff was titanium white. It's the ghost of Bob!
With the rust under that passenger side dash and the white powder on the back of the radio control module, I say flood car unless the powder they use in the airbag charges causes metal to rust...
Great job Eric, the reason you're the last resort is they don't understand some things take patience and knowledge and you have that. This type of situation this 2018 Malibu is going thru won't be funny when it's people's dashboard gauges. It'll go blank and it'll be no idea how fast you're going, no idea if you're over heating, no warning lights, no knowing what gear you're in in some cars; it'll be just black blank. The worst thing they ever did was put screens in in place of gauges. We all know how long cheap Chinese tablets last and that automakers aren't going to last very long, they want the car/truck to tear up and you keep trading in for NEW NEW NEW as you bankrupt yourself. On a side note, if someone could figure out how to get these newer cars to work with the old dashboard gauges they'll become wealthy. Just measure and make one that fits that has real gauges. The automakers went with screens because they are cheaper for them to get than old school real gauges, so their greed told them buy the cheap screens and then tell car buyers that it's and upgrade and charge them more. I look forward, especially now with the push for EVs to see the big three finally bite the dust.
Can't overly stress how awesome your work is..especially when diagnosing a problem.. So often a lengthily process, but you Always come up with a solution. Bogles my mind. And no, I you can do it, I can do it....Don't think so.....(Im colour deficient...lol ). Kudos to you Eric
As far as the HVAC trying to communicate with the radio, I have a 2016 Malibu, and when you turn the AC on, or turn the blower up or down, it displays it on the HMI.
For someone who is not into electronics much, you have the "let's cause a fault and see if it complains!" technique down pat! Software people do that all the time. Sometimes we get very excited about getting a DIFFERENT error message.
Eric i'm about 10 hours north of you ...Too dam cold out You must have the java juice going this morning ...cheers as i head out to the painter booth : ) with the thermos on
HVAC needs to talk to the radio so it can lower/raise blower motor speed as not to interfere with phone call clarity. When pushing the steering wheel call button to initiate a voice command, blower motor speed is immediately reduced and reverts to it's set speed when the call or voice command is terminated.
I see a bunch of people taking about the $1,500 core charge. Here's the thing, when an item has an abnormally large core charge it usually means the stock of rebuildable inventory is low,. That can be due to low volume or just customers never returning the old cores. You can see this just looking at auto parts stores where sometimes the new items are cheaper then the reman parts after the core is added. I know CV axles are a big thing I used to see. A new CV shaft would be about $100 and a reman would be like $60 but add a $150+ core charge.
When I went to school for Automotive Technology back in 2016 we had a case study of an older Cadillac that wouldn't start because it had a bad radio. At that time, the communication between ALL modules was serial and if one went down, all communication was lost. How would you like to tell a customer that the reason their car won't start is because it needs a new radio? Things are getting better; cars aren't "just transportation" anymore. And as far as people who say "They don't build them like they used to", a 1980s or later vintage vehicle was considered "junk" after 100,000 miles.
I have a 2012 Silverado and about two years ago the digital readout on the radio started to go black and then sometimes half of it would come back and it just keeps doing that. The radio still works so I just use it that way rather then get raked over the coals by the local GM dealer to fix it.
been a few years but IIRC, the airbag module and such talk to the radio for On-Star purposes. I wonder if that's possibly a flood recovery car. Wet SDM will eventually set off an SRS. That rust is a signal...
the HVAC talks to the radio so that the radio volume can auto-adjust to a higher volume when the blower is on high. Similarly, Pontiacs had the transmission talk to the radio for a louder volume when you were traveling at higher speed.
Great video and I like the way you posted it before the replacement part arrives and you find out if you nailed it or not. That takes confidence along with some actual guts!
Nice logical diagnosis. I do not have the cajones to short the digital com line to ground. I would have been okay just confirming that the module connector was receiving communication.
HVAC likely communicates with the radio to send visual updates to the screen when you adjust the settings. That's certainly the way it's been on my previous Honda and current Acura. CAN BUS is bidirectional so you don't know by reading it whether the communication is coming from the module or elsewhere. It would be nice if there were an easy way to disconnect the individual pins from the connector and plug them into a repeater/logger that also has a connection to the plug, so that you can tell when the module in question is sending the message.
My wife's car had the same problem, it's a 2018 Chevy equinox and the dealer had to replace the whole radio and screen. That was in 21. Since then she has had XM radio for free. Must be some kind of glitch.
XM is a one way communication. Every so often they send a command to all radios and if one of the serial number matches then the radio disables itself. They can’t send millions and millions of serial numbers so the old ones are removed. Here’s what I think happened. That radio module must have been turned on by a parts swapper and activated with the free trial period. Then someone figured out whatever problem it had was still going on and swapped the old module back in. That test module then remained activated but left in a opened box to rot on the shelf for years since no tech would dare try it. Then someday the dealer ran out of parts and decided to just chance it. It fixed the problem but XM forgot it needed to deactivate that serial number so it will never send a command. That car will forever and ever have XM radio.
@@markm0000that's awesome info. Always wondered why my '05 Chrysler T&C had infinite free, at the time, just Sirius satellite. I felt guilty and like they were going to find out and backcharge me for pirating so I never used it. Then again I was a 2000's kid brainwashed to obey anti-piracy laws...
@@KillaninjaFC same here I was always afraid of ripping CDs to put on my iPod because of those scare tactics. In high school I went full fedora hat and pirated the snot out of everything I could find. I had every song and movie on my iPod and it was amazing. Even nowadays I never go to the movie theater or watch TV. I only pay for TH-cam Premium because, for now, it has a lot of convenience over piracy. Time will tell how YT manages to screw that up as well.
@@markm0000 I wanted an iPod Video so badly for that very reason, you lived a lucky and charmed life for those days dude. Nowadays I am all about the second-gen iPod, with the greyscale screen and capacitive red backlit buttons... Anyways, back then it seems like the focus was not on improving services or accessibility to media like people wanted, but just suing and shutting everything down. Now the studios claim they're losing money on streaming services, but perhaps it is less money they're losing compared to that wave of full-fedora piracy.
Funny that a GM radio issue shows up on your channel. Just yesterday I was setting the clock on my '15 Silverado and I accidentally switched the language setting to Spanish, then the touch screen wouldn't let me go back to English. Disconnected the battery for a couple of minutes, pressed the brakes a couple of times thinking it would drain any residual voltage. Reconnected and it still won't let me change it. Going to try it again with a longer wait time. Guess I'm going to have to learn Spanish.😂
Not the case here, but the white powder does bring up something that you might want to consider. You never know what you might run across in some of these cars, especially auction cars, these days.
Had a similar white powder inside a late 90’s GM radio that was eating away at the traces. Like an acid. Was told it was a powder that formed from the deployment of the airbags. Not seen this before other than that one radio. Wonder if that powder is from airbags and it’s eating away at the traces on that radio module as well.
u r awsome wish i would of had u to teach me years ago. if u ever meet up with ivan at his place i would love to meet u. u are a great insperation. thank u so much for all u do.
The white powder is probably from the passenger side airbag charge that blew during the accident. Edit: embarrassing spelling error.

Um pulling the network to ground, to set a code in another module to test network integrity never would have thought to do that. Going to stick that one in the old memory bank. Thanks Eric, learn something everyday.
Eric O, you are, undoubtedly, the trouble shooting and electron king! I have been watching your channel for years, and you gave me the confidence to keep my 05 Hyundai Sonata rolling down the road, here in the rust belt of the Peoples Republic of Minnesota. Money light came on last week, trouble shot it down to the engine coolant sensor, good power and ground, let's get after it!
Please let this video turn into a trip to Wilbert's. Please let this video turn into a trio to Wilbert's.
Per your comment at 12:57 you should change the name of your shop to Avocas Shop of Last Resort
Love it! Hilarious... 😂
Repair and despair under one roof!
Coffee an SMA, nothing could be better
One heck of a core charge there! I do hope you have a part 2 so we can see if it is more than a plug and play. I'm guessing there is more to it than that. I enjoy your videos.
If it is a vehicle that has been in an accident most of the modules do not like the shock of a heavy collision & most likely damaged the board or other micro chip components that is why can be repaired.Cheers Mr O.
"Sultans of Swing" in the background really brought me back to the days when i was working with my dad in the cabinet shop. I know the YT will come after ya for the copyright if it ever was prominent, but it made my night just ever so slightly in the background behind your voice during diagnosis. Good memories. Thanks dude.
A lot of good detective work in the comments. Unrelated, my wife's '22 Equinox was getting a morning OTA update a few months ago. Well, there was an issue with the connection, and the radio was bricked in the process. She was heading out of town that morning! We were able to get it replaced under warranty.
Breakfast and SMA, sweet way to start my day. 😊😊
Perfect Sunday description.. SMA + Dire Straits Sultans of Swing = Awesome!
I've been listening to the sultans of swing by the dire straights every day for the last week.
A new SMA video drops with none other than the sultans of swing playing in the background.
Love it, this song always reminds me of road trips with my dad and brother growing up, he loved that song.
15:23 If I had to guess, I'd say that white powder is cornstarch. It's used in airbags to reduce the friction between folds of plastic bag as it inflates. Since the car had inflatable restraint codes, that would make sense.
Mystery white powdery is the passenger airbag and the rust is from the broken windshield it made letting in the water
There are a couple of clues here that are telling. 1, The fuse was replaced with a higher value. 2. Someone had the access covers off that area. If I were to guess, it appears that something happened to that module during the crash that caused the fuse to blow. Somebody tried for the 'easy fix' and just replaced the fuse with a higher value. This is NEVER a good idea. The fuse s meant to protect the circuit. Putting a higher value fuse will allow more current through the circuit that it was designed to handle. That is almost a sure fire way to destroy the device that the fuse was protecting. I have seen people do this with old valuable vintage guitar amps and totally destroy them.
Fuses protect wire not loads. If the load needs a fuse, it usually comes with it separately. If the load is not damaged, it won't pull any more current than with a smaller fuse on the wire. If the load is damaged, it might pull more current. Now we're back to protecting the wire. But if you put a larger fuse on the wire, whatever short the load has is just going to finish off the load. But the load was already damaged.
Agreed....if the data was correct, I'd have replaced the fuse with a 15 as shown on the info.
Brian May or Tom Scholz would never do that to a guitar amp....but I can't speak for the rest of us guitar players.😀
White mystery dust, airbag dust?
The higher rated fuse is the first thing Eric stated after checking the scan.
That dust on the module might have been that fire extinguisher residue?
Or dust from the airbag.
That's exactly what it is.
@7:00 you said UQF then went to the diagram and pointed at uqf and then went straight up and said it was on pin one. UQA was on pin 1 and uqf on pin 8.
Great diagnostic, Eric! Curious to see what happens with the new radio module 🙂
This sat open in a salvage auction yard for some time. Great parts car.
NORDO is the way to go. Anytime I turn on the radio all I hear are commercials and blah blah blah. Did you know Casey Kasem is still on the radio with his top whatever countdowns? Who knew. He just keeps on going and going and going like Bob Ross. Is it a happy radio? Maybe that white stuff was titanium white. It's the ghost of Bob!
With the rust under that passenger side dash and the white powder on the back of the radio control module, I say flood car unless the powder they use in the airbag charges causes metal to rust...
I believe the radio and hvac talk together just for temp display.
Great job Eric, the reason you're the last resort is they don't understand some things take patience and knowledge and you have that. This type of situation this 2018 Malibu is going thru won't be funny when it's people's dashboard gauges. It'll go blank and it'll be no idea how fast you're going, no idea if you're over heating, no warning lights, no knowing what gear you're in in some cars; it'll be just black blank. The worst thing they ever did was put screens in in place of gauges. We all know how long cheap Chinese tablets last and that automakers aren't going to last very long, they want the car/truck to tear up and you keep trading in for NEW NEW NEW as you bankrupt yourself.
On a side note, if someone could figure out how to get these newer cars to work with the old dashboard gauges they'll become wealthy. Just measure and make one that fits that has real gauges. The automakers went with screens because they are cheaper for them to get than old school real gauges, so their greed told them buy the cheap screens and then tell car buyers that it's and upgrade and charge them more. I look forward, especially now with the push for EVs to see the big three finally bite the dust.
Boy I wish these cars had more stuff to fix. Ya, I am old. Great work from Eric.
Josh is going after that brake disc
"dead or alive you're coming off"
😂😂😂
Can't overly stress how awesome your work is..especially when diagnosing a problem.. So often a lengthily process, but you Always come up with a solution. Bogles my mind. And no, I you can do it, I can do it....Don't think so.....(Im colour deficient...lol ). Kudos to you Eric
Breathin' heavy boss.
You go on n' breathe heavy, Mr. O.
As far as the HVAC trying to communicate with the radio, I have a 2016 Malibu, and when you turn the AC on, or turn the blower up or down, it displays it on the HMI.
I have an Australian Holden version of the Malibu and HVAC info does display on the screen.
For someone who is not into electronics much, you have the "let's cause a fault and see if it complains!" technique down pat! Software people do that all the time. Sometimes we get very excited about getting a DIFFERENT error message.
What a clever idea to test for the integrity of the data bus!!!
White powder on the radio module must be the packing talcum powder from the airbag (deployment)?
Must be solid Gold with that kind of Core Charge
I am super excited for the part 2.
Eric i'm about 10 hours north of you ...Too dam cold out You must have the java juice going this morning ...cheers as i head out to the painter booth : ) with the thermos on
Miss the days where this was as simple as replacing the radio with a better aftermarket option
Good morning, Eric. Excellent as always.
You had mentioned that it might be a collision vehicle, perhaps that tough actin tinactin is residue from an airbag going off?
Thanks for the tips on how to do electrical trouble shooting!
I am having the same problem with a Chev impala. Thanks for the video!
HVAC needs to talk to the radio so it can lower/raise blower motor speed as not to interfere with phone call clarity. When pushing the steering wheel call button to initiate a voice command, blower motor speed is immediately reduced and reverts to it's set speed when the call or voice command is terminated.
Another great diagnosis Eric!
Thanks Eric!
The white powder is from the airbag that deployed in the crash
I see a bunch of people taking about the $1,500 core charge. Here's the thing, when an item has an abnormally large core charge it usually means the stock of rebuildable inventory is low,. That can be due to low volume or just customers never returning the old cores. You can see this just looking at auto parts stores where sometimes the new items are cheaper then the reman parts after the core is added. I know CV axles are a big thing I used to see. A new CV shaft would be about $100 and a reman would be like $60 but add a $150+ core charge.
The 20 amp will be replaced with a 15 amp i in the circuit right~another great visit here..Thanks Eric
Yep radios should play music and music only Abs should control brake stuff nothing else its getting crazy
When I went to school for Automotive Technology back in 2016 we had a case study of an older Cadillac that wouldn't start because it had a bad radio. At that time, the communication between ALL modules was serial and if one went down, all communication was lost. How would you like to tell a customer that the reason their car won't start is because it needs a new radio? Things are getting better; cars aren't "just transportation" anymore. And as far as people who say "They don't build them like they used to", a 1980s or later vintage vehicle was considered "junk" after 100,000 miles.
How about a car that won't start because of a bad exterior drivers door handle...
I have a 2012 Silverado and about two years ago the digital readout on the radio started to go black and then sometimes half of it would come back and it just keeps doing that. The radio still works so I just use it that way rather then get raked over the coals by the local GM dealer to fix it.
been a few years but IIRC, the airbag module and such talk to the radio for On-Star purposes. I wonder if that's possibly a flood recovery car. Wet SDM will eventually set off an SRS. That rust is a signal...
Like Joss Stone sang, " I've got a right to be wrong ".... Good going guy, Happy Holidays.....M.J.G.
the HVAC talks to the radio so that the radio volume can auto-adjust to a higher volume when the blower is on high. Similarly, Pontiacs had the transmission talk to the radio for a louder volume when you were traveling at higher speed.
Great video and I like the way you posted it before the replacement part arrives and you find out if you nailed it or not. That takes confidence along with some actual guts!
Nice logical diagnosis. I do not have the cajones to short the digital com line to ground. I would have been okay just confirming that the module connector was receiving communication.
Nice diagnosis thanks Eric!
HVAC likely communicates with the radio to send visual updates to the screen when you adjust the settings. That's certainly the way it's been on my previous Honda and current Acura.
CAN BUS is bidirectional so you don't know by reading it whether the communication is coming from the module or elsewhere. It would be nice if there were an easy way to disconnect the individual pins from the connector and plug them into a repeater/logger that also has a connection to the plug, so that you can tell when the module in question is sending the message.
At hospital and you popped up, don't have much say don't know much about GM. Keep up the good work
My wife's car had the same problem, it's a 2018 Chevy equinox and the dealer had to replace the whole radio and screen. That was in 21. Since then she has had XM radio for free. Must be some kind of glitch.
They replaced the screen because dealers like to shotgun stuff to prevent comebacks.
Comebacks are on the technician's dime.
XM is a one way communication. Every so often they send a command to all radios and if one of the serial number matches then the radio disables itself. They can’t send millions and millions of serial numbers so the old ones are removed. Here’s what I think happened. That radio module must have been turned on by a parts swapper and activated with the free trial period. Then someone figured out whatever problem it had was still going on and swapped the old module back in. That test module then remained activated but left in a opened box to rot on the shelf for years since no tech would dare try it. Then someday the dealer ran out of parts and decided to just chance it. It fixed the problem but XM forgot it needed to deactivate that serial number so it will never send a command. That car will forever and ever have XM radio.
@@markm0000that's awesome info. Always wondered why my '05 Chrysler T&C had infinite free, at the time, just Sirius satellite. I felt guilty and like they were going to find out and backcharge me for pirating so I never used it. Then again I was a 2000's kid brainwashed to obey anti-piracy laws...
@@KillaninjaFC same here I was always afraid of ripping CDs to put on my iPod because of those scare tactics. In high school I went full fedora hat and pirated the snot out of everything I could find. I had every song and movie on my iPod and it was amazing. Even nowadays I never go to the movie theater or watch TV. I only pay for TH-cam Premium because, for now, it has a lot of convenience over piracy. Time will tell how YT manages to screw that up as well.
@@markm0000 I wanted an iPod Video so badly for that very reason, you lived a lucky and charmed life for those days dude. Nowadays I am all about the second-gen iPod, with the greyscale screen and capacitive red backlit buttons... Anyways, back then it seems like the focus was not on improving services or accessibility to media like people wanted, but just suing and shutting everything down. Now the studios claim they're losing money on streaming services, but perhaps it is less money they're losing compared to that wave of full-fedora piracy.
Always good to stick to the way the factory made it but in this case would an aftermarket radio do the trick?
GM tech here. We have also been seeing a lot of Human Machine Interface control modules (HMI modules) go out on these cars.
Causing no display picture
Fabulous diagnosis learned a great deal
Radio talks to the HVAC to decrease the fan when on a call using bluetooth I believe.
hopefully u keep churning out one great vid after another, eye no u will, thanks for posting
Damn Eric, you have outstanding diag skills, but I still long for the simple days of me being a mechanic, mush easier to diag problems.
Funny that a GM radio issue shows up on your channel. Just yesterday I was setting the clock on my '15 Silverado and I accidentally switched the language setting to Spanish, then the touch screen wouldn't let me go back to English. Disconnected the battery for a couple of minutes, pressed the brakes a couple of times thinking it would drain any residual voltage. Reconnected and it still won't let me change it. Going to try it again with a longer wait time.
Guess I'm going to have to learn Spanish.😂
Nice hearing “Sultans of Swing “ by Dire Straits in the background.
white dust=airbag deployment dust?
That's what I thought as soon as I saw it
Same
Last evening I went shopping to a local "Walmart" substitute, and Sultans Of Swing played on the radio there too....
Not the case here, but the white powder does bring up something that you might want to consider. You never know what you might run across in some of these cars, especially auction cars, these days.
Had a similar white powder inside a late 90’s GM radio that was eating away at the traces. Like an acid. Was told it was a powder that formed from the deployment of the airbags. Not seen this before other than that one radio. Wonder if that powder is from airbags and it’s eating away at the traces on that radio module as well.
u r awsome wish i would of had u to teach me years ago. if u ever meet up with ivan at his place i would love to meet u. u are a great insperation. thank u so much for all u do.
You got to watch those rebuilt cars. I know "experts" that say they are never the same. All those rebuilders are scammers!!! 🤣🤣
Some even build curb jumping death traps...
Hi Eric . The white dust could be corn starch or talcum powder. From the air bags.
