DODGE RAM 5500 OVERHEATING P0692 FAN CLUTCH CIRCUIT DIAGNOSIS

[@stealthg35infiniti94]

Great job Eric. I've learned the hard way, never assume the parts the previous technician replaced was good. Always start your troubleshooting from scratch.

[@crashoverride328]

Agreed, sometimes the biggest mistake you can make is to assume that just because something is new it must work. Sometimes all it means is it isn't rusted in place when you need to change it again.

[@robertmedina6875]

Great point 👍👍

[@notsureigaf]

Yeah, seen too many situations where the brand new part (usually some gibberish-named knockoff from Amazon) was worse than the old one, though in this case the previous "mechanic" simply lied altogether. Hope the Ram guy can get his money back somehow.

[@jasonmorales1846]

These type of videos are better when mistakes are left in.It shows you are human and how you corrected the issue.I appreciate you doin that.

[@roxanneabbott8424]

Awesome work Eric!!! A true mechanic with full disclosure!!!

[@EATSLEEPFARM]

I feel like i repeat myself on every one of your videos but ive gotta say it again. You explain whats going on during a diagnosis better then ANYONE on youtube. Explaining the bias voltage from the pcm is using that as a test for the circuit then showing it loaded… 👏 👏 👏. Thats the type of stuff alot of people would skip over or assume alot of people would know. Great stuff as usual brother 👍

[@onlinemn]

I love the way you explain electrial diagrams, it's nice to see people who truly understand them , when I went to vocational school years ago one thing my instructor inculcated into our heads was you need to understand basic electricity and schematics to ever make it in the field, to this day I continually use what I've learned even though I'm not in the business of car repair but I still do it for lots of friends and relatives because there is a lot of mechanics out there who do not understand how to or even repair electrical problems or even do this kind of Diagnostics , I am in the electrical field , I do lots of problem solving that other electricians cannot figure out by the way. Keep up the good work and making the videos that are truly impressive I can not imagine how much time you spend making them, hopefully someday you'll be able to hire your son or (daughter if you have one) to edit them for you like a lot of other KZbinrs and they can make an income also and enjoy doing what they do. Have a great day.

[@jgeorges3061]

ERIC, UR truly a technician with integrity and honesty who every one would love to bring his vehicle to you to fix the right way as u did with this one as always AWESOME information and approach thanks for sharing.

[@ignacioromero5014]

Hey bro new subscriber from Los Angeles, loving your tenacity to hunt these issues down, I'm a novice car mechanic, only really work on my own cars (BMWs/Chevy 1965). Keep up the great work!!!

[@Stevme0001]

You always make great videos! This one is no exception! Keep them coming.

[@unclemarksdiyauto]

Eric, what a fantastic diag! Whew, dodged a bullet not calling it a $4000 computer and being wrong. You always do a great job of thinking things through. Customer should also be thrilled! Thanks again for posting, we have all learned something on how this circuit works.

[@charliemendoza4032]

Your the best and honest Eric, Keep up the great work. I am always learning new things from your videos. People these days buy cheap used parts and install them without knowning it could be defective. Being honest and informing the customer of the repair with detail is always the best way to do it.

[@mikechiodetti4482]

You found the problem and fixed it......period! GREAT DIAGNOSIS! If that's a Cummins engine and fan unit, they have a pretty thorough diagnostic test, in some cases you have to know "Cummins Speak" but once you've done one, you'll know! My knowledge is limited and it was over 6 years ago working with a Cummins CNG engine. Fun time!

[@706redpepper8]

Thank you sir for this full in-depth diagnostic , I just replaced my clutch fan and after pulling a load of 28k. My truck was doing the same and the diesel shop I went to was doing the same Diagnostics and same tools you have and you have now proved that my pcm is still good and I’ll be getting a different brand

[@Mahees_230]

Pisses me off to see a customer get jerked around like that on such a simple repair. I'm glad you could help him out.

[@sambitar8448]

ERIC, YOU ARE A GREAT DIAGNOSTICS TECH AND WELL AWARE OF THE INCOMPLETE OF TECHNICAL DATA PROVIDED TO ALL OF US IN OUR FIELD. YOU DEFINITELY VERIFIED THE ECM IS NOT BAD. CONGRATUALATION ON A JOB WELL DONE.

[@stencils118]

Another great video, thanks for the upload! I love how you still keep your videos real and don't try and bullshit your viewers by editing out the 'mistakes'. It's the 'mistakes' that help us all learn. Also it's so much tougher when the manufacturers don't share important information regarding how a system works or what sort of readings you should expect! Looking forward to your next video!

[@riblets1968]

I'm an old school auto and truck mechanic that enjoys auto diagnoses videos because I hope to learn something about modern vehicles and; by and large, I have. However, one thing that I've heard on other videos by other mechanics before but never understood was the idea of a bias voltage. You, Eric, were the first to actually explain what it is and how, precisely, it is used for auto system control. That was very, very cool! You're a born teacher! Oz is pretty good at it too but I really like how you go out of your way to explain things to us knuckleheads. Much appreciated, sir!

[@truth4reel]

Awesome. Called possible bias voltage from the 3.9v right away. He should've come to you in the first place. Some people only give me the head scratchers and take the easy jobs to someone else.

[@roooon2]

truly a technician with integrity and honesty

[@deankay4434]

I like it, from a retired ASE master! Why, when the service tech uses common sense and finds a problem, it becomes fixed. I don’t like PWM fan clutches but this is the world of lower emissions and higher fuel economy we live in! But you have to verify the customers concern, then following “TSB’s” if any, then diagnose the root cause. Too many repair the symptom and replace a part. Go to the parts store and let them read the current code. Just understand if it says “O2” sensor, does not mean it is bad. Too low for long time, too high for long time, heater open, high resistance because a new exhaust had an O2 wire melt on it. You see, the code only points to the component, but does not diagnose the real reason. Parts stores enjoy selling $170 heated 4 wire O2 sensors, but it may be correctly reporting a problem as say the fuel pressure regulator is dripping raw fuel past a ruptured diaphragm (If Yours Has One) but in this case, the O2 is reporting a rich mixture over a long period of time (Varies by Manufacture) but is fine. Complicated? Yes, blame the Government for CAFE standards, CARB for setting expectations for emissions, EPA for the rules and marketing for noise, safety, and MPG and others like crash testing to set insurance rates. Then how big the city is, number of accidents, deaths, theft as you move into the country 200-300 miles from a big city, your rate can drop 39%. Fact! ASE master tech since 1978.

[@wolfnorth7075]

Eric. thank you for a very detailed electrical fix. Among every auto fix, electrical ones are the hardest. you have shown us honestly on your fixing. BTW, I do rant this world a little, you do deserve a shop to help people out.

[@sambitar8448]

ERIC, YOUR THOUGHTS AND DIAGNOSIS ARE SO LOGICAL AND WELL ORGANIZED BEYOUND WORDS DESCRIPTIONS, THANK A MILLION FOR YOUR EFFORT. RIGHT ON THE MONEY.

[@TheCrazy243]

Great video! I misdiagnosed my friend’s car. Her car couldn’t move backward. Thought it was suspension related part or transmission . Turned out brake pad were came loose. Pad material were gone. Rotor was thin! Not an expert in Suspension system… I’m a young tech..so I’m constantly learning! It’s a pain but crazy! You are very honest and I learned a lot from you!

[@NorthShoreJoe]

I have watched almost all of your videos, you are so good at explaining things in detail. Thanks for all of your great videos.

[@neilmurphy845]

I'm glad that you left the mistakes in the video because that's how thing's work sometimes

[@gabrielsaldana8913]

Another great video, excellent troubleshooting I really enjoy watching you diagnose problems ,the way you explain things is very clear and concise, I'm a retired Master Tech of 40 years and I'm still learning, Great job!

[@The_Redkween]

Awesome job, Eric! That was some first-class diagnostics, there and proof that experience really does make a difference. The experience gives you that instinctual “gut feeling” when something isn’t right.

[@michaelshadwick3487]

I've recommended your channel before seeing this video.. now I'm thinking that I cannot advocate your work enough!

[@2eagle86]

I've seen other mechanics here but your very thorough and fix everything at the end I'm glad I found your channel

[@gilron9585]

I like that you do double check everything and treat the customer's money like it was yours :)

[@goducgo]

I watched the whole thing. Great video.Finding a great mechanic is the hardest most expensive part.

[@VashthStampeede]

I cannot believe how many times technical information called it a clutch fan. A clutch fan, if one really exists would be a device that cools your clutch. A clutch may indeed overheat and be in need of cooling, but I know of no device designed to do so. A fan clutch, on the other hand, would be the proper device to engage the radiator cooling fan. Just one of my pet peavs. Just saying. Great video Eric. Keep 'em coming.

[@samrugtiv3839]

Eric very very well done my friend i worked on the cs at the dealership 35 years .Well done sam

[@stephencook4611]

It's nice to see your back in the saddle again. Look's like all is well with you. Hopefully you are back on track.

[@turtlebro4498]

Awesome work Eric. I was out of town working one day when the company truck a 2017 Ram 2500 was having a similar issue where it would heat up and reduce the speed it could be driven when towing a trailer. it was a 16 foot enclosed trailer with maybe 1,500 LBS of extra weight aside from the trailer. should not have been an issue. i towed the trailer with my truck so we could make if to and from the hotel but we finally took a look and there was a small connector in the shape of an L that came from a hose and connected to a pipe that keep breaking. we replaced it with an identical unit and it broke. so we grabbed some fittings from home depot and a hose from autozone and replaced the piece. has worked like a charm since then

[@foxwithtubesox1075]

Awesome episode! Glad to see the whole diagnosis process. Big props for your honesty and including the part where you got sidetracked.

[@faustogonzalez8397]

Absolutely awesome Eric great work, I learned quite a bit and as always when you make a mistake , it stays in your mind and you remember for a long time !!

[@Joeschmo63]

Your troubleshooting skills impress me more every time I watch you working your magic. Love this channel!! 👍👍

[@HP-mx6jb]

This is the difference between a code reader mechanic and a technician. Troubleshoot till you can verify the problem and repair.

[@chuckvoss9344]

Thank you for the thought process. The bias voltage was an eye opener. Good job!

[@DanielSan-ch7dr]

Glad to see you back in the field and making videos again. It was a shame to lose your shop but most your work seem s to be on site anyway so no point paying for something that your never at. Love your work and have learnt alot from your videos.

[@franka2507]

Nice diag. You did due diligence which saved the customer tons of money.

[@ecaparts]

Thanks for the case study Eric!! What a great feeling you get from almost misdiagnosing a job, but end up rechecking and finding something totally different. A great learning experience! It’s best practice to NEVER assume anything and to test for yourself (even if a part is new or someone already ‘diagnosed’), then recheck if you have an unexpected result. Great work! 👍

[@maddenterprisesllc.3914]

Great video I learned a lot Wish you would’ve showed taking out and putting fan clutch back in. You took your time overall with a customers vehicle and didn’t just do some random ish. Very thorough I’m sure your clientele loves you.

[@dave0z96]

Today wasn’t a waste I leaned something from this video . Nice work I’m subscribing .

[@Silentb00]

Another great educational video. Learned a lot from it. Your number one in my book. You a true diagnosis you add teaching in your videos and it helps a lot.

[@biglevstergarage]

Great job Eric, you are awesome no matter what. Everyone makes honest mistakes and has to clarify errors in their minds. Just shows you care about the quality of what you do. Also shows you are a legit honest mechanic.

[@kellyx57]

Thanks for explaining how the bias voltage is used to verify circuit integrity. Nice work!

[@aaronfox5808]

Thank you for leaving and explaing the footages , great for younger newer techs to learn from.

[@themechanic6117]

I'm sure the customer learned their lesson and won't take their truck back to that "mechanic" . That harness coming off the fan clutch didn't look new to me.great video

[@frankjohn4302]

It's good to show the human side of things. You got my respect when you worked on that flooded out lexus

[@snakecantu]

Long Video. BUT so much helpful info. My old 2005 Dodge 2500 had a similar problem, wasn't to replace the freaking expensive computer. So this explains some of the issues and unknowns i was dealing with. Learned about the load test, so when my buddy replaces the Tranny on my old Dodge I can help him figure it out so he can maybe get that old 5.9 to 750k.

[@gerrylarson3675]

Wow, pretty good. Thanks You're lots quicker than me at getting out of those rabbit holes in good shape!

[@fmbfla]

Good save on the explanation at 15:50. When something is PWM, pwr or gnd contl. I Always look at the PWM sig First this can tell me if the controller is actually working and if there is a pwr or gnd error then the check pwr and grd wgile doing BI/D/C of the device. 90/100% should mean full pwr or full gnd else 20% or less is opposite

[@fmbfla]

And as I watch the end of the video I see my self 5 years ago Fudge yea ! Member dat day! And put DAT on a Cracker DUDE!

[@kenbowden4965]

Love your videos. You are truly a great mechanic and system analyzer. Your explanations of complex systems are great. Just wished you were closer to where I live.

[@dansaver8247]

You're a terrific mechanic. Good job done.

[@adrpals2324]

Good job. At my job when someone does a repair and the machine is still not working. I check the tech's work first. I've found a few times that they made a mistake.

[@e.l.9589]

The amount of information is appreciated, even if I have no issues.

[@bartscave]

Thanks for showing everything! I wish service information would mention bias voltage.

[@stevenbarber2703]

love your videos i love car videos i am going to be a mechanic the more vids i watch the more i learn thanks for your time and videos :)

Nice job ! Unfortunately some scab took the truck owner for a ride. I learned a lot about the pcm voltage from you,thanks again.

[@W.Khairi]

Hats off, U deserve every penny for the excellent diag.

[@robertmedina6875]

Great video Eric!! I actually did know about bias voltage… how ever it slipped my mind about Chrysler using it🤷Great job teaching us! We are all human 👍

[@danielfarmer4311]

Your a class act man. Great work! I love the part about guys that know everything. No kidding! Love the channel man 😎🇺🇸

[@danielgreenbaum8875]

Thats a great video Eric and explaining bias voltage and always test and not guess as seen ecu put on cars as they not checked wiring and rule out new parts already fitted that are faulty or been broken when fitted

[@hairolf4397]

Amazing work eric! Thats a really good point on the biased voltage & that is something that we need to keep in the back of our mind when troubleshooting. Salute to you sir!

Awesome diagnostic! Great job.

[@CrazyPetez]

As usual, great trouble shooting Eric. I’m surprised the PCM is bolted to the engine block. I would have thought a computer would not be so close to a big heat source. It seems modern computers aren’t as sensitive to heat as old ones.
