(Pt 2) HELP! My Toyota is STILL STUCK in 4x4! ('02 4Runner)

[@tomtke7351]

Possibly you edit it out... but I never see you responding as I would when crap happens. When confusion strikes you might say, "interesting," or maybe, "dang," but I never see you tempted to toss a wrench across the room with great velocity. I want that ability!! You seem to treat every blockade as opportunity for great discovery of earth's greatest secrets. And I want this talent/skill. Restated: you don't seem to have resistance to persistance; you easily (or so it seems) to 'keep on dancin' ' whenever crap happens.... AND I WANT THIS ABILITY!

[@Andy_Hinners]

" I never see you tempted to toss a wrench across the room with great velocity." You oughta see some of the tantrums that Eric O doesn't quite edit out. Ivan is a serenity now Buddhist Monk by comparison. My guess is that what Ivan edits out are the lengthy pauses when he walks away to think it over and regain his composure.

[@franklaumen77]

O-oh, interesting or 'ow crap' seem to be the available error codes that Ivan is programmed to show in case of misdiagnosis 😂😂😂 Wondering what the non substituted obd2 values and codes look like for Ivan 😂 What scanner do we need for those?

[@user-pq9ji7kt4l]

He does say. ‘What the heck !’ Which can translate to lots of things!!!!

[@SmudgyContent]

Dude he’s 23yrs old. U see his gray hair? Keep tossing wrenches

[@TheOnespeedbiker]

Ivan as an compulsive problem solver, he gets a dopamine rush as he approaches the solution, the more complex the problem the greater the high. So when he sees a complex problem, or one that he does not expect he says it's "cool" or "interesting" as he anticipates the dopamine high when he finds the solution.

[@billziegmond4943]

Old school diag brings me back to 20's. Your are right Ivan. Makes you appreciate scan tool data.

[@gutsngorrrr]

This is what I love about Ivan, he guarantees his diagnostics and repair and won't charge for an incorrect diagnosis and associated parts. Not many places will do that, they will just keep throwing parts at a problem and charge the customer, even if it doesn't result in a repair. This is how all places should work.

[@Malc180s]

When you own a property and don't have to pay rent, insurance, staff etc you have that luxury. It's a nice way to work. When you've a big garage with cars coming through all the time, it's just not possible. You have to charge for your time.

[@malware_in_tn9008]

Ivan, you and Eric O are national treasures. No mechanic at any dealership and very few independent mechanics go through this effort to fix older cars. They play fast and loose with customers’ money and just fire the parts canon too often. I salute!

[@jeffcompton6937]

Too many customers assume because it's a dealership they shouldn't need to pay for testing or as many hours of testing because they're just supposed to know, more experienced etc. Reality most dealership techs on average don't even have 10 yrs experience on the brand so the older stuff isn't familiar. And the older stuff isn't easier to diag because there's less data to interpret. The quality of diag directly correlates to what the customer is willing to invest in a diag. Most customers don't wanna pay for the answer they want you to guess then take all the liability and responsibility.

[@dw-bn5ex]

While your ability to chase the wiring is truly admirable. We must remember that anything exposed to the weather, wiring, switches, motors, etc., is the most likely point of failure. Where I live road salt and green ground wires are a way of life.

[@davidzelkowski9948]

That was quite an exhaustive diagnosis. Well done! For me I would have had to walk away from it for a day to get a fresh perspective on what was going on.

[@DonDegidio]

Hi Ivan, Good sleuthing without proper documentation. Hope the switch is available new at the dealer and not expensive. You and Amanda stay safe.

[@TheOriginalDaveJ]

Many a garage would bill for a faulty diag, not our Ivan tho, he'll keep that spare module for a rainy day😉

[@alexanderzubar9593]

Ivan, the diag on this unit should be charged per hour since there is not enough service info on the 4WD operation. Your experience from previous diags should be compensated appropriately. When I do diags on things that don’t have service info I charge for the time NOT a flat diag fee. Plus , now that you’ve generated that truth table of switch states you are going to help someone else who watches IMMENSELY!! Great job in keeping your COOL 😎🧊when you hit a roadblock.

[@brandonhill88]

I've learned from the Master techs at my shop to start at the axle disconnect by plugging in a known good. Then, if there is no change, remove the rear switches and test those on the bench.

[@rog8201]

I’m so thankful you took the time to show us the new module didn’t work and continued to work on what’s next. I definitely respect not charging the customer for the part but also understand that time is money and sometimes getting to the solution takes both. Those parts probably don’t fly off the shelf on eBay but I wonder if it could be resold by the customer to recoup their money as an alternative. I know it’s ridiculous but having a known good part is sometimes needed to get past what’s left. I wonder how many parts get repackaged at a dealership by a tech realizing they were wrong too? Probably happens a lot more than we know. I’ll have to watch this 10 more times to track your process and see if I can follow your steps to success. Thanks again.

[@TheOnespeedbiker]

Ivan really opened my eyes to understanding the logic or programming of a module, this is a perfect example. You could have a mechanical failure that results in a sensor telling the module of the failure (or a module not getting the antipated electrical feedback) and the module would then shut down or go into limp mode to protect the drivetrain. This makes it appear there is a module or electrical fault, when the problem is mechanical (or in this case a hybrid mechanical/electrical problem with a switch).

[@farmermiyagi1338]

Makes me appreciate my 95 base model Ranger that much more. Boys there is nothing to piss you off like no call, no show customers. Well, okay, it would have pissed me off had it not been Friday. I just rolled the doors down and went to the river. XD Speaking of river, I hear it calling this morning.

[@steveharrigan1296]

Ivan you are truly an impressive technician. Really enjoy watching you figure out this problem.

[@frankvucolo6249]

OK, that was brilliant. Take this car to 100 techs and how many can get here? Ivan, you are worth every dollar you charge!

[@major__kong]

In the first video, I mentioned possibly using an Arduino to replace the module if the module wasn't available because it's basically a state machine. But the first step is to simply verify the state machine is working correctly by measuring the value of each switch in different shift positions and comparing to what it should be. It might have been a fun project to quickly build a breadboard with an LED for each switch so you could see all the states simultaneously rather than switch test light and multimeter leads around. I'm pretty sure a modern version of that box would be reporting states for each switch in scan data. If so, this would have been a quick diagnosis.

[@Roboticdoughbull3k]

Well we all learned a little something here today, no harm no worries well done after all Ivan.

[@rjm7168]

My original guess was a bad position sensor in the shift motor assy but you were so sure it was the module (which in my experience is usually never the culprit). For the GM NV246 transfer case, the internal sensor is available. For Toyota, you may need to replace the entire shift motor assy. The symptoms seem very similar to the GM NV246 bad shift motor position sensor. That 4WD detection switch seemed to work. We'll find out if it was bad in part 3.

[@GeneG-wk2mz]

He’s the man in my Shawty low voice 💪🏿❤

[@tanglerd]

as a former Toyota Master Tech, I HATED 4wd problems during that era since the service info was Horrible.

[@NoName-yr1jv]

Well done Ivan 👍

[@dannyhawkins7229]

When you were moving the motor by hand I thought one of those switches must be bad...and I was right! Does that make me a youtube certified mechanic? LOL!

[@stevenakn1]

That's why alot of these trucks have been switched to Bluetooth front drive shafts 😊

[@MrTonyPiscatelle]

Reminds me again of that stupid suburban I had, that rig on a Chevy is called the transfer case encoder motor and it works with the axle locking device in a very similar way and it will make you want to pull your hair out trying to figure out what part is bad. Nice diag logic Ivan.

[@Andy_Hinners]

"will make you want to pull your hair out" Maybe that's why Ivan favors a short hair style . . . nothing to get ahold of.

[@MrTonyPiscatelle]

@@Andy_Hinners That Ivan ain't got no quit in him. He's like a bull dog.

[@Andy_Hinners]

@@MrTonyPiscatelle Cerberus and Charybdas got nothin' on him!

[@normyanke2515]

How many toyota dealers shops would figure this out, I suspect none. Without Ivan's methodical troubleshooting skills, this vehicle would never work properly again. As an electrical electronics engineering technologist, where did Ivan pick up these skills? I love his videos, todays mechanics have to be part electronics technicians, are they getting this training,? particularly with the EV's coming along. I see a whole new trade evolving to meet the need to support EV's. In the meantime I see a huge problem as these EV's age.

[@bugzie-a1769]

You are so good, may god bless you,

[@sebastiaanfellinga4413]

Thanks Ivan

[@richardnilsen5]

Notice the technique = goes for the moduel first easy accessibility does measurements,different shift positions,makes a chart,does intense visual inspection gets to the problem. Awesome 🎓👍🅰️♦️🇺🇸💰 Textbook💪

[@greggc8088]

I hate Toyota's 4WD control system. Not enough info available. Toyota has a class for their techs and the course book is a valuable piece to have since it covers a wide range of years. Thankfully the Domestics allow you to use scan data PID's rather than having to back probe so much stuff. Good diag!

[@crisprtalk6963]

I will never be this smart. I'm OK with that.

[@GNX157]

Well, you’ll have a module to add to your parts inventory for the future, or maybe eBay sale.

[@poq600]

Nice diag ivan. However, Early on you were seeing confusing voltages, which usually points to confusing resistances and amperages. Wouldnt you agree that Focusing on and eliminating the exposed switches first would have saved you time and money. I do enjoy my 6am wakeup diagnostic videos. Thx

[@aciddiver1978]

Lets keep all systems simple, i says. Including 4wd systems.

[@riblets1968]

I miss the 4WD mechanical levers and manual locking hubs. Sigh.

[@sspnugen]

Owning a 4Runner is not like owning a Camry for a long period of time

[@jbfrank7519]

😅plastics, the bane of my existence.

[@williamwhitehead8362]

I had to change the transfer gear oil to full synthetic, an then it works!

[@ChesterChin-q5f]

Have a 2003 Tacoma and that happens to me a couple of times before and all I did is clean and lubricate the actuator on the front diff and it’s good as new

[@Z-Ack]

My tacoma did something similar. The rear differential lock would get stuck and not cone out of lock.. you gotta put it in neutral to lock the diff. Neutral for 4 low also. 4 hi can be engaged when stopped or going slower .. i ended up running wires directly to the lock motor and bypassed the sensor so i can just hold down the power to the motor and get it to lock and unlock.. because the sensor would stop the motor from being able to do anything and i would have to lift the rear to unlock or lock when it got stuck.. so after running the wires everything works and if it gets stuck i just hold the button. Got a lock and unlock rocker switch..

[@nickchannel5364]

How do you keep your composure so patient and scientific? That problem would have sent me around the bend.

[@kerrylewis2581]

Lots of brain exercises in part two. Not to mention how many times Ivan crawled under the 4Runner. Will part three be the key to getting the owner back on the road?

[@johnz8210]

Difficult. I looked at a random transmission trouble code P1782 for 4wd in a Motor manual and it has some troubleshooting trees. Basically what you did but at least it was there to follow. There were no codes in the trans. of that 4 Runner?

[@Tivver]

That is an amazing logical diagnosis. Took a while but you got it!!

[@ericknutson602]

Ivan, what does the owners manual show on operations?

[@vicferrarisgarage]

I own the exact same 4 Runner and the Diff lock is in back axle. Has Zero to do with 4x4 transfer case. This was a great fix but has zero to do with the Rear differential locker!

[@brianw8963]

That’s what I was thinking, but I lost my taste for shoe leather, so I didn’t say anything.

[@peterbenson3776]

I wanted to jump in and ask questions lol i know with the Old Ford Rangers to get to 4Low you needed to be in Neutral with brake depressed. I was wondering if the diff lock was front to rear or just front axle.

[@ToxicwasteProductions]

That was a very interesting video. :)

[@vicferrarisgarage]

Back when Toyota was great.

[@chekelley6861]

Of course it doesn’t work. It’s full of nacho cheese! Who would do that?

[@tomtke7351]

You sell merchandise, right? Wby not resell the box you just bought?

[@Ben-says-you-are-AWESOME]

The fact that there's a part 3 makes me think that there's a bit more to it than just fitting the new switch! 🤔

[@volvo09]

That switch certainly appears flaky, but if it's not the switch I seriously wonder what the heck it could be. Maybe he'll find a separate issue on the test drive, since this hasn't been on the road yet, just back and forth in the driveway...

[@x01e]

The wiring diaghram part is too hard to follow watching the video. This is the case allot of the time unless its well explained.

[@guess1866]

started to fry my brain till you got it working then switched centre diff on theres your problem lady that circuit not showing operation completed

@ the first time was on another vehicle. this time when he ordered box off ebay. ivan never fires the cannon until recently.

[@shakalpb1164]

It happens

[@shakalpb1164]

When you don’t have the precise module information it’s easy to misdiagnose for a faulty module
