What I learn from these videos is to always buy the simplest car I can find with as few options as possible.

All that trouble to clear a DTC! And what a convoluted process to get there! Manufacturers do like to make it hard on others. But you managed to do it, despite all their obstacles 🙂

I always like programming modules, makes me feel like I actually know what I am doing.

What do you mean, "The customer will have to pay for this." Of course they will, Ivan. He's got you as a technician; he should be glad to pay that! Great video!

Thanks for posting this video. It made me understand what i am up against as an owner of this series of suburban. Greatly appreciate the info.

Great find and fix Ivan. Lots of patience involved on this one.

What a horror show nightmare for consumers 👹👹👹👹👹👹👹👹 Great video 👍

Your videos are awesome Ivan!!

I had a 2003 with the same issues with leveling system compressor was bad shocks were shot too was quoted $2500 for repairs more than vehicle is worth I said no way. I searched found how to delete the electronic leveling system put new standard shocks all around and air bags in rear springs to the tune of $500 plus my labor. Works fine for me!

Wow! That was complicated and so detailed!! My hat's off, Ian!

Its crazy of prices go up but wages stay the same in most fields. I run my own business so charging alittle more isn't a huge deal but still has its problems. My wife works at a hospital and its almost insulting the bump in pay she got. I don't even want to mention school loans. This is the first time in my life I've seen prices skyrocket across the board. I remember years ago gas might raise then next year food goes up alittle but this time it was a slap in the face. I just can't believe that everything and I do mean everything has gone up.

Ivan, thanks for sharing ALL your diag and repair insights AND comments on YOUR channel.

Definitely not a repair for diy . Nice work Ivan .

Another epic fix-- Ivan is tenacious. :)

Exceptional Series 👍.

Ivan, great video on jumping thru GM hoops to clear all codes after replacing a module.

it should be like the old windows computers- when you buy a car it should come with a disc with all the programs on it please dont wake me up this is a nice dream !!

Gracias muy buen trabajo Caballero

Hi Ivan, Great you were able to solve the problems, but you sure had to jump through some hoops to finish the job. Stay safe.

Great content Ivan

Wow. Thanks Ivan!

Great find and fix

I'm sure other manufacturers do the same thing, but what a Pain In The Ass period! Fortunately you had availability to the on line Tech 2. That Tech 2 is an amazing diagnostic tool. Coupled with the on line programming makes the job complete. Maybe the aftermarket diag tool tool companies didn't want to pay extra for the "trimtest" thinking the tool user wouldn't need it or something else. GOOD WORK IVAN! You definitely earned your money with this one!

Thanks for sharing.

That was really interesting, thanks .

Wow nice work ,

Quite a circle jerk Ivan. Even with numerous high end aftermarket tools, GM makes sure they get their cut. Pico scope gets you on the path but is unable to finish. Too many diagnostic tools out there that just "won't or can't" complete the job. I feel your pain. Retired from Gm service 5 yrs ago, had an escm make me chase my tail for quite a while. Intermittently had high internal resistance within the module. Finally it stayed broken long enough for me to test across the comm, terminals with an ohm meter. Exhale and move on.

Excellent !

Great fix and interesting programming. As a DIYer with a few (older) cars the OEM tool subscriptions get to me, it's not like they're adding and new features, fixes, etc for a car from 97 or 00 so why can't I buy the software once. I understand subscriptions on newer vehicles there might be new things added over time to the software.

should be quick.....famous last words....especially with GM....good luck Ivan.

What a process

Thanks Ivan, you did everything exactly how I would have done it. Only difference is that for me it would have said "DTC clear failed".

Vehicle industry says "Yes you can have right to repair, however its going to cost you every step of the way ha ha ha......!" We need open source modules !!

Great work Thanks

meeen i've not seen the beached whale series yet i think am missing put, am pumped ... gonna buy some popcorn and watch it tomorrow night

Great content 👍 👍👍👍😊

Nice job

I'm at the point where I'm purchasing multiple subscriptions daily. There are just so many vehicles now that aftermarket scantools don't work with when it comes to writing data. What's even worse, a lot of scantools will report a success, while the module is still derped.

Wow, electronic control module Failed!! But you got it to work but sucks for client to pay for it. As if he wanted that done. That's the cost for it. Great job Ivan!! So complicated job to have to use tech 2!! Wow. AT LEAST it's done right!

I mean, why not put a computer under the vehicle where all the water and salt live?

ALC trimset basically resets the rear suspension height for the load leveling air shocks. GM vehicles with MR shocks and rear air leveling use the same logic.

One quick observation why GM did not put the module inside the car some where, lots of space. The programing procedure was nutty!

Wow ! tech 2 brought back memories from working at a holden dealership in the late 90s to early 2000s , they also had some antique looking scan tool before obd2 . Very basic but it did what it needed too . Great video Ivan 👍

Hi Ivan, thanks for your educational video's, keep them coming! Are all 4 suspension sensor connectors identical on this Chevy? If yes, maybe swapping them randomly would recognise the sensor replacement, force the ESCM module to re-learn and automatically clear the C0558-4A code. But if the sensors are simple 3-wire potentiometers, this would probably not do the trick. Looks like the internal voltage reference circuit gives off the wrong voltage. If the circuit board is not covered by epoxy coating, I would start with a visual inspection of the module. There could be issues caused by vibration like broken tracks or solder joints. Even water intrusion could be the cause considering the location of the module. If all seems okay, it can be a faulty semiconductor, leaking/shorted capacitor or other component. Would love to see the faulty module opened and inspected/diagnosed by an electronics engineer. Greetings from Crete in Greece.

Nice vedio

Nice

Making a call on a module is like diffusion a bomb😮‍💨💨😂👍

Thanks Ivan! As soon as you said Saturn Astra I broke out in HIVES! LOL. BTW The Astra passed inspection this year flying colors after I replaced the exhaust pipe with the crack flex pipe. Greek is a Happy Camper. You and Amanda Stay well my friend.

Correction. You just have to pay for the passtru which can be a few hundred to a thousand depending on the car.

Ivan I'll have to fire up my old Awfultel & double check it because I'm 99% certain I've done a trimset/recalibration on a 2010 GM(Holden) with it before it became a Paperweight! Knowing Autel they probably removed that functionality after glitches appeared in their Backwards Engineering process!

Your to smart man. GJ

You are amazing ! If you're in western mass, I have a 08 Mdx I bought . Love to have you talk to it.☺

Wow very cool video. That was an incredible amount of useful information thank you !

Great job and PHD go hand in hand.

Buffalo rocks !

"No diagnostic trouble codes" --- woo hoo!!!!! I could see the flood of emotion on your face and the neurons firing those hormones. lol What a relief when it's over

When customer purchase ECM or other modules. I tell the customer. The modules MAY need to be programmed. The next question is. How much?$$ I tell them. That depends on the shop and their prices. I don't tell them the shop rates. Because of the price flucuations. I'm a DYI and have not tried programming modules since I don't have a pass thru device yet. I watch Dr. O programming. I know it cost $$ to get access to program and get access to wiring diagrams. For my own use. I use Alldata. Good night Ivan and thank you for dragging me along.

So much complication - The oil-based suspension-system on my series of Citroen cars - a system invented c 70 years ago, was a delight - no electronics involved until 2000 - ish - only replacement/recharging of suspension spheres after several years of use. The KISS principle applies! LOVE your posts - you're certainly NOT a 'Quitter' Cheeeers Keith

What about the processor for THE on STAR system(VICM) ??? or was that also a coincidence on the no start. Do you know what was shared over the network keeping the vehicle from starting ?? Did the BCM and or ECM receive a high voltage signal(higher than what was shown on the scan tool at the suspension module)over the network to keep it from starting as a failsafe operation ?? Well then come back next week 😉

Every time I program a vehicle, jump thru all the same hoops and finally get it done I can't help but wonder how it's so easy to do a cell phone update and it's free in comparison. It's not data volume, Cell Phones hold a lot of data also... I think it's just because by law they can make it difficult for the aftermarket, so they do. I guess if the law didn't force them to allow us, we wouldn't be able to at all...Which brings us to needing to have a locksmith license for newer vehicles now. :/ Nice work Ivan! Btw I have the same Mastertech VCI, good tool.

Seems to me they should provide a “day’s” access TO the Tech 2 as a certificate or reimbursement with the purchase OF the OEM module since it’s all a part of the changeout!

Great vid, could you pull the tip off the old module?

You lost me on that one, but it was interesting for sure!

the S/W subscriptions were pretty minor compared with YOUR LABOR HOURS. Always intriguing how (as you say) "convoluted" things can get. BTW.. in my industry we had a standing procedure when connecting or disconnecting any connectors to always inspect. LOOK CAREFULLY AT BOTH MATING HALVES FOR: (-1-) Bent Pins; (-2-) Pushed back pins; and in your field (-3-) Green crusties. This includes new assemblies. After inspection it was critical to NOT FORCE THE CONNECTORS TOGETHER. No, "hammer to fit and paint to match!" ADD: Did the customer just not have a spare tire that would then offer ADDITIONAL mechanical protection for the replaced module? You suggested they removed it for you but I wonder if it's permanently missing? Just my 2c.

amazing what it takes just to repair these over complicated stabilization systems, !'ll keep my simlple shocks and springs than u !, once again great job of taking the time to do the job right

Thanks for another great video! What a headache. When it says "remove all weight from the vehicle" does that include the tech? 300lbs could make a difference, no?

Tech2Win really emulates the legacy Tech 2. That procedure he did was literally updating his virtual Tech 2 the exact same way as if it was a real handheld tool. Don't bother trying to program modules with a clone Tech 2. Ivan already knows this. I used MDI direct from SPS and it worked great after major struggles with my clone Tech 2. I have a 4 part video series about this ...

That module looks exposed to road debris strikes without the spare tire in place. Maybe it's not just a coincidence that the spare tire is missing...could rocks and such debris bounce up there and hit the module?

Do have a place that you know in southern California where I can take a 2020 suburban. Replaced all OEM SUSPENSION PARTS and still doesn’t ride well, the only part that I didn’t replace is the module. But all the places that Ive taken it including the dealership don’t seem to know much about Magnaride sistem

Before calibration: remove excess weight from vehicle...Think that was you Ivan ;)

On older vehicle with comm issues I like to use the data bus diagnostic tool with the j2534 it’s accessible in the tech line connect home page where you launch tech 2 win, it will tell you voltage and if you have shorted can bus or bad module power, ground etc.

Nice series. This programming stuff makes my hair turn grey. 😂😂

I may be done. All this new-fangled voodoo high-tech wizardry is immoral. Take me back to the pre-high-tech days. It wasn't THAT bad, and almost anyone could work on a car. The very idea (in this case) of having to pay over a hundred dollars to gain access to his own vehicle's software! Criminal! And that's after an $800 module! I may be moduled out. I love learning from you but it's really bringing me down.

GM could have found a better place to mount an $800 component inside the cabin. Bad GM, Bad GM! Go stand in the corner.

As if anyone really needs this complex suspension system.

👍👍👍👍🌷

Do you think letting the air out of the rear air shocks and letting the truck redo itself would’ve done the same thing other than using the tech to?

So, did leaving that fuse out for Telstar fix TCM comm. problem?

Ivan did you need the spare wheel in place for the calibration?

Hi Ivan could that module have anything to do with the CAN bus peoblem as it was faulty

Strange that an issue with the ESC would muck up the TCU that way and lead to a possible misdiagnosis.

Got 2007 Yukon any ideas how I can takeoff the dash suspension warning after I took out the stock struts and shocks front and back?

Tech too software main menu reminds me of windows when you have to use safe mode

Its seems like a scam. You have to pay for one program to calibrate the module and then pay for another one to clear codes. They get you coming and going.

Would the tools Pro not allow you to clone the old module and then reinstall it on the new module and code it

*WHAT?!* No Russian repair! LoL 😂😆 Great job!

When the module gets installed does it require the air out of suspension system so it's at zero??? Must be something in installation process from manufacturer.....

Can't find the ride height controller on the car in my profile picture!

God, they spared no expense on that DOS with graphics like interface...

I guess a dealer would have been the right call for the fix.

Any thoughts on a DIY J2534?

What size bolts hold the module down?

Manufacturers continue to put electronic gizmos in the most vulnerable places - under the car instead of the cabin.

Wow. Cannot believe how clunky looking that Tech 2 software is. Reminds me of what old DOS software looked like. I guess if it still works and people pay for it, then why update the appearance?

$800 module? OUCH

What scan tool are you using?

It still bothers me that the CAN problem isn't really solved. Yeah it could be the onstar but it wasn't consistent. Seems like there was more going on. May not be enough to justify spending all day chasing ghosts but don't think the CAN problem ever really got fixed. Did you plug that back in after changing the ESCM? Too many variables.

Pretty cool that you had a tech 2 on the pc, I wonder if the VCMI from my ultra would work as a pass through for that ?

The underside of a car is an excellent place for exposed electronic components.

That is weird, how software programming has to do with inflation looolz its all online, internet fees went up 😂😂😂😂😂
