SOLVED my U029E with "Exhaust Fluid Service" and "Reduced Speed". For the past month I have been working on this issue on my 2017 Silverado 2500HD LT 6.6L. Tonight I purchased my 3rd NOX2 (downstream) sensor and IMMEDIATELY EVERYTHING WAS FIXED. So, what happened? Why did the previous 2 NOX sensors NOT work? A clue came from GM Parts Direct as the original part number was listed as "DISCONTINUED". Previously we had purchased 2 numbers matching NOX2 sensors 12676706. So why did these sensors not work when the one see image below immediately worked? CHEVY! They programmed out part number 12676706 from the computer and programmed in 12718676. 12718676 CURED OUR U029E and "Exhaust Fluid Service" and "Reduced Speed" issues. Companies are still selling NOX2 part number 12676706 because it was the original device DO NOT PURCHASE THE DISCONTINUED NOX2 SENSOR 12676706. INSTEAD PURCHASE THE 12718676 PART NUMBER.

Do you have to disconnect the battery before removing that fuse box from the connectors? Or is it ok to leave the battery connected?

Hey DadsGarage , I have a 1999 Silverado starts then dies . Can you please help me understand which code scanner (diagnostic tool ) I need to repair my truck . How good a scanner should I buy ? Can you recommend a brand and model ? Thank you much !

I just had this done a couple of weeks ago at my local Chevy dealer on my 2015 3500HD Dually with 88K miles. I Barely Squeaked in with just under 10 days left on the 10yrs/120K miles warranty, (Whew) otherwise I would have had to either do it myself or have it done by my Awesome Family owned shop here in town. It Saved me a Bunch of $$$ having GM pick up the tab on a POS Poorly designed emissions system that Shouldn't be on there in the first place !!!🤬

Got the U010E code this morning will look at that harness this evening.

I would never buy a 3.0 duramax, this is ridiculous.

Can they still fold??

Holy crap always check them bolts 8:30 found loose once whole vehicle freak out

How do you do a diagnostic test like the one in the video where could I get one done at and is there a name to the test

Are you supposed to do a flush or a filter replacement?

Multimeters don’t really pick up the draw from the starlink system as it uses power in pulses. A picoscope picks the little spikes up easily.

2016 Chevy Cruz LS 1.8 automatic I have it at the shop right now and they’re currently trying to figure out what the issue is with my vehicle putting another transmission and it’s still not communicating with my vehicle 😢

What’s crazy is I have a transmission shop doing the TCM right now. They actually replaced the entire transmission, but they called me telling me that it’s still not communicating with my vehicle. Sooo at a lose rightnow

Saved me a lot of time mate. Excellent video. Subscribed 👍🏻🇦🇺

How about explaining what you’re doing, why you’re doing it, what the results are and what they mean. I could crawl under my vehicle and spray my catalytic converter with soapy water and not say anything too, But what does it mean ? I learned more by reading other people comments than I did watching your video.

Changed battery and this silly warning came on. My truck has only 19,000 miles. My diagnostic tester will not erase it.

I inherited my father’s 2019 Outback wagon upon his passing. Sat for like ever. I drive it three times a week and had to replace the stock battery. New battery like others have said in the comments worked for months and then all the sudden after sitting for 2 days is dead dead. Jumped it and hoping it’ll be ok for awhile. Alternator shows it’s putting out as it should. So it has to be a parasitic draw issue.

More an attitude problem ie I did my part it’s not my problem then leave

Amazing Job

❤❤❤

Could you possibly list a part number for the module? I’m pretty sure I’ve found what to buy but I want to be 100% before I pull the trigger.

I accidentally put 2.5 gallons of DEF in my fuel system For my brand new 2023 f350 and drove about a mile and my truck started to sputter. I immediately pulled over to a nearby Wawa gas station and got my fuel tank drained because I knew I had def in the fuel system. I got it drained on the spot and ran a few gallons of diesel to flush even more out and than I completed filled the tank to dilute whatever def was still in the system and I put a super concentrated bottle of fuel treatment in the fuel tank. The truck was able to run without the sputter but I had a huge loss of engine performance because the system detected water in my system and recommended me to drain my fuel filter. I drained it and all of my power was restored. I even drained the filter a second time for good measures. I drove around until I got down to a half a tank of fuel and I fueled up again to the max a couple days ago. It’s been 3 weeks since the incident and the truck is still fine. I called around and was looking at online post. All i been getting was “that truck will never start again” and “you screwed up your truck. It’s over”. A lot of you guys tend to exaggerate. I’m not replacing my fuel tank and lines and pump. If you catch the problem early enough you will be fine.

thanks for the video , does this work for long mileage cars , mine 260k KM second hand never been flushed and i got TCC shuddering (60-80 KM speed ) , other functions working properly

My cousins 2108 Impreza goes dead overnight if she leaves the key in the ignition. Dont know what is doing it, but the simple workaround was to always remove the key.

We're looking at the battery neg still connected. And you're removing the fuse box.

Hi how do you flash the system?

ive been dealing with this code for too damn long, i already spent 6k on a transmission shop and they couldnt fix it and told me not to bring it back......no honor or backing in their work. so given how this cruze looks identical to my 2014 impala lt 3.6 flex fuel, im going to take apart the fuse box and see, test for continuity from the box to the connector also. it has a new TCM in it, not even 2 weeks old. the way my car is right now, i cant use it for work because it wont past inspection.

is that being blown by an exhaust leak or boiling off?

Where r u located? I need someone in sacramento california that does your job with the similar knowledge

So good! Just subscribed 👍🏽 Appreciate you sharing your problem solving process instead of just here’s how you fix it

Great info, thank you for posting!

He could have started it up 😅

Yes my uncle had one he was a left handed machanic wish I knew what happened to it. My grandpa would pick it up to use it and get mad and throw it down.

What is that he using to put on the glasses

Were do you get piece from , and what's it called

Thank's so much ❤❤❤❤❤

Same fucking problem on my shitvolet Fuck this car. Garbage designer (GM)Garbage motor-vehicle

just replaced the ect sensor and thermostat on my 2018 3.6 canyon and my truck still will not get up to operating temp any ideas?

Yeah sounds like my 6.2L at 65k on it

Thank you so much! Fixed this exact issue on my short bus!

how many pounds of torque the guide bolts are

😂😂😂😂😂sopletea el lente ...te ca a quedar lindo...

Where did you do the exhaust side leak test? I have a 2018 Cruze, I was thinking to smoke the exhaust.

Can someone explain to me why my 2019 l5p and my 06 lbz both have the same injector 4 issue? Had to replace the whole injector on my l5p now not sure about my lbz?

yo i got one of those elm327 dongles and idk if mine is fake but theyre complete garbage. sometimes they work, sometimes they cause a canbus error and throw every code imaginable and put the car into limp mode. i would reccomend if anyone has that dongle, never leave it plugged in and only plug it in if you have a way of disconnecting the 12v battery like a cressant wrench since that was the only way i was able to clear all the codes and get the car out of limp mode with another scanner to clear codes.

How much was that module?

❤❤❤❤❤

What an insane way they make you have to fill it up!!

what do you have to do after the repair to get the flashing light to go away?
