Buick LaCrosse: No Start No Communication 

Another Fun Fact: South Main Auto Repair is one of the reasons I no longer have to suffer through network TV car shows...Great entertaining content with a touch of pathos (I too have psoriatic arthritis so I dig your annoyances... ) with just solid mechanicing (as we say in the south).

And finally...the lawn mowing neighbour is right on cue 😎👍🇨🇦

Nobody's talking with each other. Sounds like one of my family reunions... Eric, only you are lucky enough to drop a 10mm socket in a salvage yard engine and not have it be swallowed. Great job!

Rough roads cause torque on the tires that is transmitted to the powertrain. This slows down the crankshaft giving the appearance of a misfire. The electronic brake control module (EBCM) determines rough road surfaces using input from the wheel speed sensors. The EBCM then sends the rough road data to the engine control module (ECM) via class 2 serial data. The data allows the ECM to distinguish the crankshaft speed variations caused by rough road surfaces from those caused by true misfires. If a loss of communication occurs that causes the PCM not to receive rough road information while a misfire condition is requesting the malfunction indicator lamp (MIL), DTC P0318 will set. Basically one of his wheel bearings or the wheel speed sensor is fucked.....

After watching 30 seconds of this video, my advice for the no crank situation is "jiggle the handle and make sure it's in Park" Having now exhausted my supply of expertise I will watch you actually fix the problem. It's a good thing they brought the car to you instead of me

Another great diagnosis - but hats off too to the 'other shop' who recommended the owner take the car to you.

“What we’ve got here is a failure to communicate.” 😎 -from “Cool Hand Luke” (1967)

Just when you thought it couldn't get any better it turns out Eric O appears to be a Led Zeppelin fan into the bargain.

I'm an old 8 bit computer programmer... You are the 1st auto technician I've ever heard who knew what a UART is! Well done sir!

Trinity is growing so fast! Watched an old sma vid when she was like five. Damn I'm feeling old. Lol

That guy cutting his grass stopped the moment you left for Wilburs, and started right back up the moment you got back lol

That is the neatest most organized junkyard I ever saw.

That is the cleanest junkyard I have ever seen. Well organized and heck even the fence looked good

I love it when you take us to Wilbert's. I'd love to have a place so close to be able to just hop over and pickup any replacement parts I happen to need.

You had me cracking up with your mechanic's country song! Every light in the dash is on. That's gotta be the saddest song ever 🤣🤣🤣🤣

We definitly need a "rest of the story" on this one. Would love to see you solve all the problems on it.

Don't feel bad Eric. The PCM was in the airbox back in the old 3800 days. I still get burned on that once and awhile.

Nothing as attention grabbing as a good ol' arbitrary deadline! I'm on the edge of my seat! 😂 Another great video!

I'v come here for 7 years now, all for the mowing ASMR sounds. Sorry (my guy) Eric.O 🤣

I always feel like a better person after watching Eric’s videos. Good dude.

Wilbert's is nicely arranged. I like the gravel everywhere. No mud like most salvage (junk) yards this time of the year.

I helped my buddy find a parasitic draw on his old shhhhevvrolayyy..... All thanks to the SMA archives ... It turned out to be the common issue with the instrument cluster... Man, a lot of folks here owe you a beer or ice cream....

Great diagnostic and repair. A relief after coming from another Kilmer drunken rage video.

Love the long SMA videos!! (Heck, who am I kidding, I love 'em all). Bonus trip to Wilbert's!! Thanks as always, Eric!

I see the neighbor is back to his daily lawn mowing

Sure sign of spring at SMA. The lawnmowers are out of hibernation. :) Thanks for another educational video.

It must be greatful to have Family to watch over you at work. JMT'S

One of the greatest bands of all time

EO I am very impressed at how clean and orderly that salvage yard is! Over any years at many junk yards and never seen one that nice n neat!

That guy cut that grass the entire video 😂😂😂

Hey Eric I think we are all wondering what you were late for, anyway cool video

Work fascinates me, I could watch it for hours….

Eric O, what about the wire by the oil filter? You left us hanging, my guy.

I always enjoy a trip to the pick & pull. Great diagnosis and repair. 👍

I find it funny every time I go to the boneyard or even people on YT people only bring a handful of tools and then there's me who brings literally a wagon of my tools including an impact or ratchet.

Eric, you know I love these diagnosis videos the best, and this was one of the best. I'm amazed at how you can focus in on the exact location of a problem, I've stopped guessing on the diagnosis, as I'm always wrong. However, in this case I hoped you would find a random wire ungrounded, which some knucklehead at another shop missed.

Just to make me feel like I can contribute: Universal Asynchronous Receiver-Transmitter. 😁

My goodness your daughter is grown up so big and looks just like her mom!! All the best from Surrey BC Canada

You can tell summer has returned because the lawnmower guy is back at it. Love the videos.

Great video as always. Just one question:. How big is your neighbor's yard? Takes them forever to mow it.😆

Thank you Eric for another great video. Yes we are weirdos, work on cars all day then watch someone else doing the same thing after hours. It is a sickness!

You wear that tool belt clip like a Boss!!😄👍

I love the fact that your viewership means so much to you that you intentionally took the wrong thing apart so that we dont feel so bad everytime we do it ... Great video as always one2BBq

Peoples republic of New York 😁 or peoples republic of China all the same, and yes “stairway to heaven” is one of the greatest songs, these are great videos.

Also..GM Has a new code..the FU 1000..LOL😁👍🇨🇦

You and Mrs. O Are quite a team. I truly love watching you guys.

Wouldn't be a sma video without lawnmower running in the background. Another great video Mr.O.

As a retired mechanic (in the UK, where nearly all the cars are European or Asian), I enjoy seeing the way you diagnose and fix these problems, because I don't have to any more.

That guy must have a really big lawn!

I remember decades ago when I lived in Rustchester, going to Arthur Wilberts for Buick stuff. "For a Buick part, call Art!" they said. 😄

I love the videos that start with troubleshooting and end up at the Junk Yard - it's just like home. My local yard (I call it my Gift Shop) is 20 miles away so I'm not able to visit as often as I like. They run the dogs right up until they open in the morning to discourage snakes from hanging around (it's AZ, after all). Please keep up the good work. ALL of your videos are valuable to so many people.

Seen equally useful ecm locations listed as "engine bay" and "outside of engine bay". Real useful!

What we have here, is failure to communicate!! Some cars you just can't reach. So you get what we had here last week. Y'all know the rest. Thanks for the video Mr.O. God bless you and your family.

A most pleasant surprise coming home from work, all of you O’s rule

ALWAYS love a good diag video.....and it's always best to learn from one of the best!!! Thank you thank you!

Is there a lawn mower testing facility across the street? My guy has been mowing the lawn all day!

never been to the Bath location closer to Williamson, but love the place, saved so much cash going to yank it myself. Reminds me I have to get some rims for my daughter's prius this week

Amazing Mrs O is every bit capable of dealing with all Eric can dish out no doubt. What a lucky man.

Well done, MyGuy ! 😛

cool hand luke, what we have here is a failure to communicate

That powertrain was actually one of the better ones GM had back in the day. The 3.6 V6 with a four speed automatic can hold up for a long time. The question was always around the electronics back then, which is the case here. I always learn from these videos, thank you for sharing. Thanks for sharing while driving to an appointment your conclusion.

Only came to see a sight of Trin and Mrs. O, glad to see them, Trin is almost old enough to do a brake job!

Great video, the ladies of the 'O' family are more lovely with each passing day...thanks for what you do.

Geeez....a couple of months ago, some thieves were able to bypass the theft deterrent on our 05 Buick Lacrosse....started, drove it to a neighboring town and left it in alley.....though thanks to an onboard vehicle tracker, I had the police find and recover it.....

Love your videos. You are about the best and most honest mechanic I have ever seen. The one thing you say at the end of each video, “if I can do it so can you”, there is no way in hell I could do a tiny fraction of what you do.

Nice video Eric. This one felt more raw with it being outside the shop. Loved the trip to the "yard."

The pool noodle at 30:14 for the exposed windshield edge is a genius idea! Can't believe I never thought of it, I'll definitely be keeping one in my work area moving forward.

Nice video my guy!

Stairway to heaven has been played out unfortunately. Personally the song “No Quarter” has been under-rated. Good work figuring out/troubleshooting the wonders of Buick

Dang that wear-a-kit unholsters smoothly! So jelly. Also it just struck me that your neighbor was mowing THE ENTIRE TIME you were working.. even after the u-pick trip. Always be mowin'.

This was a great video "My Guy".

These are my favorite videos, I love the troubleshooting ones. Thanks again for sharing 😊. Awesome job as always 👏

Great sleuthing, Eric! Your knowledge from your experience is worth a tremendous amount. You blew me away knowing where to zero in with 20 bazillion DTCs. Amazing diagnosis and repair!

I must say that Wilbert's is the the nicest junk yard I've ever seen. Very clean and very organized ! Please take my word for it and don't come to visit California to see the sh*t holes we have to pull parts from. Love the channel !

Your dealing with the GP (general public) advice rings true to me. I led a team of technicians doing CNC machine maintenance. We had a lot of skill and experience, but frequently lacked OEM documentation. Troubleshooting particularly deep electrical failures could lead to the black hole of OEM secrecy. This juncture would get me on the phone with the manufacturer wizard "Shell Answer Man" (does that date me?). I was just smart enough to provide the wizard with exactly the data he needed to get stuck at the same place that us (me). I learned to filter the question and data to not lead the wizard down our problem rabbit trail and let the wizard "spill the beans". Most commonly, withholding information would allow the wizard to speculate down his own path and not detour where we got stuck. I usually aborted the phone conversation with, "Thank you. That is what I needed...", before he concluded his speculation musings. In this video, you easily could have started chasing pre-existing symptoms that the customer was satisfied to live with and didn't affect the issue that brought the Buick to your shop. Witholding information instead of leading the GP (customer) acheived the required confirmation without letting you wonder if you set the customer up to leave you with the same question. You are able to obtain OEM data, though at an expense, in the automotive world that was not available to us in the much smaller CNC world. Even when your service data is wrong, the specific error becomes obvious and gives you other valuable information. An old former boss self defense quote after I caught him documenting wrong information was, "A little bit of wrong information is better than no information." He was wrong in the self defense specific situation, but no information can be a dark hole of discovery difficulty. Armed with information you can save a lot wasted time and unnecessary work. I enforced our shop rule to accurately add or correct documentation when a discovery was made. Our shop kept machines for decades. Cataloging data for future reference for the entire staff was a daily requirement. We referenced this data base daily in subsequent troubleshooting. I had a particularly savey technician that wrote and in maintained our maintenance and repair software program. He created search engines to allow us to search tens of thousands of repair records in moments to find previous repair successes. This saved vast amounts of time and allowed moderately my skills technicians to effect successful repair while lacking personal technical troubleshooting skills. I labored as a technician and led the team for over 30 years. We created an interdependent team providing around the clock maintenance support to keep production equipment fully functional. You work in a "one man shop" and only need to document what you cannot remember. Around the clock production demands required us to routinely hand off incompletely diagnosed or repaired machines to subsequent shifts for completion. Logging repair documentation before leaving your shift allowed subsequent team members to understand how far you got or they could tell where you made a mistake and didn't have to go back to square one and start over. Smart technicians didn't easily see the need for "simple issue" documentation, but our less skilled staff was dependent upon this data. We set our company interest above our own egos. Maintaining this departmental culture required keen management attention. Your RU-vid video record uses a very different format to document troubleshooting struggles and successes. I have been retired for years and still enjoy sharing in your troubleshooting journeys. Modern vehicles parallel the CNC technologies that I dealt with. I regularly wished we had more complete documentation for our equipment. I don't like working on cars. The hobby mechanic doesn't have affordable access to required documentation. Industrial machinery designers give much more consideration to repair technicians than car builders. Repair access and documentation is impressively complete, even though I wished for better data. Thank you for continuing to post to RU-vid.

Thank you for another awesome diagnosis Eric! You are the man😊😊😊

Now what we have here is a failure to communicate. That was in Cool hand Luke right ? You also know we like to watch. Thanks for posting Sir.

Holy cow Wilbert’s pick and pull is unbelievably organized! Awesome Dino. Love the the the bus man you the best! I always love a road trip too! Thanks for watching! Lol bye!!!!

Making work fun again. Love it! Keep it up man!

That is a very organized and well kept salvage or junkyard,the ones here in Las Vegas is very run downed and extremely ghetto..anyhow you sir always repairing vehicles that other shops and even dealer or stealerships cannot..great video and content as always

I always wonder if these other “shops” in town have South Main Auto videos playing in their shops! Another awesome video as always!

Eric said a few weeks ago he's just a normal repair guy. He's much more special if other shops keep sending their issues to him.

Eric: Sorry...I bumped "send" by accident. that raucous damned siren across the street, loud motorcycles, loud trucks, & in this video a lawn mower running away, the loud alarm on the telephone, & God knows what else. I live in a county that has 5500 square miles in area, point six persons per square mile, 6 villages, & my nearest neighbor is 2 1/2 miles away. My electronics repair shop does not have a broadcast radio in it (unlike several vehicle repair shops in the area, that have stereo equipment running at the noise level of a Romanian steel mill. ) I There goes that damned siren again ! . Your electric fault finding is absolutely first class. I always grin when I see you use a lamp as a test load.....there are times that a heavy load(relatively) is required to duplicate the fault. Your use of a "scope on a rope" is a valuable trouble shooting tool for many things. I use one myself when working on Ag equipment. Great stuff Eric, & you are lucky to have "Mrs.O", she is a jewel. Ms. Trinity has really grown, & is as pretty as the Lord lets little girls be. Haven't seen your boy for a while (Evan ? )....he must be a teenager by now. I look at a lot of similar sites, & you have no sites that eclipse yours. Ivan, & "Scanner Danner" are both damned good, but there are many who are full of what the crows fight over. Thank you Eric for you tutelage of your followers. I expect you have elucidated a few of your professional followers as well. All the best from the minus 55 deg. F , & the wind swept hinterlands of Alberta, where men are men, & sheep are nervous. Brian

You the man Dr. O could watch your videos all day! Great entertainment!

Thanks for another awesome video..i look forward to your videos, they are educational and fun to watch...its not boring like the Florida videos..

I always enjoy your videos Eric. Keep up the great work!

Seems like Chevrolet is a popular patient of your automotive repair shop. It's so strange that an American made product could have so many issues. 😳 Your channel is the best so far. I do enjoy working on vehicles as a DIY home repair guy. I can watch your vids for hours and never be bored. The caliber and intellectual abilities in auto repair diagnostics are phenomenal even when you make a boo boo in diagnosis. Carry on and bravo...

the attitude has picked up on the young one ... mine turn 9 and 10 this year; she felt good giving you sass with momma! :D

Awesome work Eric! You're the BOSS!!

WERA kits are great for small stuff. Nice work again Mr O. That is such a nice clean organized wreckers yard. Ours here in Alberta are mudpits with junk, broken metal, and fluids all over the ground. Some cars just sitting on the ground with no wheels, no category/inventory stickers etc, Stay gold.

Love the wrecking yard trips

Sweet video thanks for sharing Eric!

Man it was a great video I learned so much from you especially about skin tools and everything else let me know I have a piece of garbage but I still learn more thank you and happy mother's Day to Mrs o please keep making videos like this because I love them it makes me happy as a retired mechanic at least I learn more 😁🇺🇸💪✌️🙏

A couple S-bombs in the last few videos. It’s strange to hear, you’re so careful not to cuss. I’m from Oklahoma via California so I can’t believe how you get through all that rust and crust without using tons of Mother F-er’s😂 Seriously, I’m happy for all your success and it’s great to see your family and business grow. So cool that you can work with Mrs. O, it’s a blessing to see y’all living “right” Thank you for sharing your knowledge with us!

Nicely graveled 👍. Great job

Great diagnostic! Love your videos! 👍👍👍

Love the videos dude keep it up 😁 great diag Mr O, look forward to seeing you next time

P.S Love watching your RU-vid videos you are a very funny guy keep up the excellent work and you are a very good instructor as well.

great work as usual always the best to see mrs o

As always, thanks for posting.
