@@Diagnosedan Hello how are you I am interested in purchasing the annual access. But I can't do the subscription for ONE year. Since I am from Mexico and the entire American continent is not considered. Only United States of North America. Which there are also technicians in Latin America who seek information and help from other countries and websites. There is something very important that large companies FORGET. THAT SPANISH IS THE SECOND LANGUAGE MOST SPOKEN IN THE WORLD AFTER CHINESE. AND THE MONEY FROM SPANISH SPEAKING COUNTRIES ALSO HAS VALUE. SINCE OUR CURRENCY IS CHANGE TO DOLLARS, EUROS, POUNDS, RUBLES ETC.
You are mostly based on european cars yet I cant find anything about Peugeot, which is very common car manufacturer in EU. I have Peugeot 308 with 1.6VTi engine (same engine is build in MINI also) , and it is very specific engine with lots of things that can and do go wrong. So it would be very helpful if you make one video about that engine. What can we do about oil consumption (some says replacment of the PCV valve solves the problem but I kinda do not believe in that statement).
Dan you are the Man ! I have a 2008 Lexus with the same issues ,you have given me the answer I needed without having the dealership drain my wallet . Thank You Again Dan your the best!
Well done yet again Dan! I had this vehicle and had this exact problem. Had I Not had a Lexus Tech on a forum tell me about the fan issue, I wouldn’t have been able to fix it. DDTSB diagnosed it in 30 seconds. If I was a pro mechanic, I’d jump on a DDTSB membership. Diagnose Dan = World class expert diagnostician. Facts.
I wonder how much suffering the guy that discovered this fault went thru to create the bulletin. Great video, and love the part about DPF. I can only wish that where I live was obligatory, no car has it.
@@basaalex3209 same here! As I wrote upper, it happened to me to drive my motorcycle behind few new cars that were (supposedly) doing the cleaning and I was suffocating...
Dan, excellent diagnosis. It demonstrates that as independent diagnostic techs we need access to OEM tech info. It would have been interesting to see if there was any freeze frame data available with the DTC to see if it showed the battery cooling fans were commanded on at the time the DTC was logged. Would also have liked to see the current trace on the scope of the old fans verses the new fans could reveal any back EMF or perhaps some AC voltage leaking on to the DC circuit. Just thinking out loud here.
These are like murder-mysteries for me. The "victim" is the car, and detective Dan will try to uncover the culprit. Who will the murderer be this week, an evil CAN bus, a sick sensor? Stay tuned to find out.
One of the MIT open course engineering videos demonstrated what "noise" would do to a chip that is looking for s clean "yes/no" (1 or 0). The data sheets for semiconductors give you the tolerance for each particular chip. "0 or NO" may be from zero to 1.8 volts. "1 or YES" may be from 3.5 to 5 volts. If voltage spikes (static) are introduced into the line, the voltage may drive past the point where the chip goes past the tolerated voltages and the receiving chips don't understand what the transmitting chip is trying to say. Odd that all 3 fans failed at the same time. It could also be that the failure of one fan would not produce enough noise to drive the communication past the "threshold of misunderstanding", but once the 3rd fan failed, it was too much noise for the communication line to tolerate. If these fans have brushes, sparking will eventually occure as the brushes, commutator and bearings wear. Side note: My cousin worked in the Silicon Valley in the early days. He told me that a big part of the code written for any program contained tons of fault checking and data verification, ie, did you put in a number where a letter was required..did you enter that you were 20 feet tall and weighed a kilo (etc, etc). Dirty connections, broken wires from too much twisting, kinks, etc caused many communication problems. The "hand shake" contained tests of communication. Good video...showing the on/off waveforms illustrated the problem very well. I will post the MIT to this if I find it.
@@danthemann6565 Hi, yes, a noise filter would do the trick, a simple LC (or a snubber circuit, or both) would "swallow" the noise created by the fans. And probably cost peanuts compared to three new fans.
A collective TSB system is the holy grail of more efficient repair on modern high tech vehicles . It the advantage of a brand/model specialist but that knowledge/information across almost all brands with a knowledge base that growing at rapid speed & lot of brilliant minds solving the normally unsolvable in minutes .
Brilliant again! I wish there were more people like you who really knew how to fix things instead of acting like they know when they are only voicing their opinion on how to fix the problem. This is why you get these jobs because the parts canon has sometimes been used and the problem still exists. Great job again, per usual. Even though you are Dutch your English is superb so congratulations on your Multilanguage skills. I have barely mastered English and this is the only language I have ever spoken!
🤣🤣 thanks for the comment Robert. most people in English speaking countries only speak one language. In Holland most people spreak 2/3 languages. But than again English is the Global universal language.
do more hybrid videos! i have a hybrid that will not start due to the hv system but it was working perfectly fine a week ago. i seen your other videos as well and they’re very informative and I enjoy watching them. keep up the good work dan!
Thanks Dan for another great video as I find them really interesting because you explain them so well. Amazing that a bit of electrical interference from the cooling fan can affect the signal on the data bus.
I have been in the trade 19 years now and I'm always learning new things. So glad I found your channel.... I used to work for Citroen/Peugeot so I was intrigued by the video you did for the 208 Peugeot you did with the Cracked cat.... I have some good information in regards to common faults on that particular engine. AND also the 1.6 EP6 engine... If I could pass on that info to your DDTSB. Just let me know.
Peugeot/citroen - my sister had a 1996 Peugeot 306 that I learned to drive in and she always said French cars are crap for electrics and brakes. How are those two items in your experience? I did end up getting a year 2000 Peugeot 306 as my first car and also had a 2004 Peugeot 307 estate. I found I was less impressed by the suspension than brake issues but the 307 did have a COM2000 unit issue which was under warranty thankfully.
I would have never tought that all 3 fans were failing. If I see that all the fans cause the problem I would think that is has to be something else. But this proofs that that isn't the case.
I'm glad you were finally able to pronounce square centimeter, but it's really measured in cubic centimeters. Nonetheless great and informative video Dan. Thanks.
I gues, the bearings is gone on them, turning get's worse and rotor contacts goes sparky, sparks create heawy noise and load induction on all wires nearby.
only 90t km on those blowers... so you need to change them every 3 years if you use the same motors... or are there some changes in the new ones. Some dc motors make carbon dust and start to make weird things but are these more ac motors whit own controllers? i hope those motors are still in warranty
Dan you really are a great technologists. you give the purchasing power to go out and buy a car , I've been without a car since 2007. I want a fullly electric car from Hyundai.
Thank you Big Dan for taking the time to make these videos, so interesting and we are all learning from your years of study and diagnosing. Cheers from us lot out here.
I continue to be amazed at your level of diagnostic skills.........Would love to see more videos on Hybrid vehicles. I have a 2008 Ford Escape Hybrid. It's very difficult to find accurate information for this vehicle. Thanks again for your great teachings!
DDTSB is the best. Great video, I always try to guess what the fault may be at the start of the video; would never have thought it was the fans. every day is a school day.
You probably get this question a lot But my biggest problem dealing with car electrical is the source for electric diagrams. I like to deal with small electrical stuff, I am not even close to what you do, you are my hero. What is the best reliable source for electrical diagrams for cars?
Hi there, I had this exact problem, A Lexus technician gave me a clue and asked me if there was anything blocking the vents and yes there were shopping bags and a Hoody. Removed items reset the car took the battery off for about a minute reconnected the battery all worked fine after that.
Dan your channel one of the best channels in youtube it theached me a lot and im going to start a diagnostic course to be a diagnostician because of ur vids my dude So dose the launch 431v+ have what you call a genaric mode and is this device any good Your the only one im going to take the word from 🤷♂️ Even if you don't see this comment thank you dan💙
Snap On is going to b mad u used a Launch. Great vid. I don’t usually like Diesels, but with the filter they r clean. What a shop u have. Thanks for teaching us!!
Damn! I wish all countries would require that diesel gas analyzer! Imagine how much cleaner our air would be... and how much healthier we would live! Thanks for great info Dan!
The way they came to a stop they looked like brushless PM motors. Like the ones in your computer. Can't argue that the fans did it but I'm not certain there are brushes in there. Manf would not want anything that sparks near the batteries. Would love to tear them apart and see if they have any filtering on the supply wires.
@@OldePhart Could be some faulty condensators in the blower motors if there's a filter inside ? No idea why the motors else would give the noise on the line......
Excellent video.. A twist from the other side... The software application have seen the problem and given us a DTC. If the application is well developed it has a ringbuffer in form of a transient recorder that records pre and post that event (DTC) automatically. Sometimes in some systems(trains) you can on top of it set the event in the software algoritm as a trigger and choose a couple of signals to be recorded (pre and post) that you suspect. But thoose functions is buried deeper inside the manufacturers system. If the systems are designed as I am mentioning you would not need to hook up a scoope to solve the problem. The surrounding information is collected and sent up to the cloud and you can see it there. But that is on swedish trainmanagement system and not on cars.
Great video Dan thanks for sharing!! Now what went bad on the old fans? It’s interesting how they bring down the network while they are still spinning fine!!!
What do you think inside the fan motors is disrupting the signal? Because I’m thinking they’re simple DC motors just like a cabin blower motor… Wear on the motor causing higher amperage? It would’ve been really cool if you had tested the amperage on the newer motors compared to the old! Are they variable speed motors,do they have a built in resistor that controls the speed of the fan? Thanks for the video! 👍
Proving the old adage that good information is beyond price.I'm retired from that job, but back in the day I wrote service and troubleshooting manuals for equipment almost as complicated - ours had fibre optic communications so immune from that nasty electrical noise. Thus I appreciate the &*)) out of good technical bulletins. Glad to see you looking hale and active.
Thanks for the comment it's appriciated. You must have been writing those manuals for something to do with Audio and Video. Fiber optic is also used in cars mostly for the entertainment system.
@@Diagnosedan Actually, it was bank proof equipment that read the magnetic encoding of the MICR line, and sorted checks in to pockets for distribution to other banks. 500 documents a minute down the track with auto-feeder, read, encode, endorse and microfilming functions plus up to five 4-pocket modules with attached printers. You think your customers are fussy - bankers can be far worse about the read rates for garbage MICR printing.
always is nice to understand new things the easy way just like you Dan do - appreciate your effort for helping us in our learning process - greetings from Caracas Venezuela to you, to your son and daughter - really like watching them helping you in your shop -
How does the scan tool turn the fans on and off, if the fans cause a no communication fault? I hope that makes sense... during the times when the network had all that static from the fans, how did the scan tool turn the fans off?
Ha good point. The fans are also connected directly to the Hybrid control unit with a direct single wire. The only thing affected was the can comm. between the Hybrid control unit and the Battery contro unit. Communicating with the Hybrid control unit was still possible
Those squentimetres are rarely used these days but I fully understand the communication between the brain and mouth can get overloaded at times. Also seeing the particulate instrument at work is scary information.
Interesting one Dan. But CAN BUS is supposed to compensate for external noise on the signal. I might have missed this if I listened to network theory! Also, no single fan was causing the issue? I wished you had diagnosed one of the bad fans to see why it was causing so much noise. But thanks again for a great video. Hybrid issues are only going to become more common.
Dan, the last time I used a particle counter was in a clean room for semiconductor manufacturing, never thought of seeing one used for diesel exhaust checking. What about using some high frequency filter caps for fan motors to get rid of noise? Great video, clone yourself, not to many techs would take the time to properly diagnose the problem correctly.
thank you my friend. The contents you provide are great but I have a question what kind of this device do you use and what do you recommend to use for Japanese and German cars to check it well
Awesome job thank you.... Mine intermittent also,... only occurred during high load... Fast speed, climbing hill. Etc. Fans were under stress. Since fans still worked, and appeared to be working up to speed, do you think they were slightly out of spec. To throw the code and disrupt the wave form??
Wonder if a new brush set would take care of the problem or perhaps a power feed circuit from the controller to the fan assemblies that has better signal filtering. I'm assuming that a cleaning of the commutator rings and new brush set would have solved the problem if they were replaceable. Increased arcing at the brush-commutator contact is probably the source of the noise that's finding its way back to the hybrid battery controller and giving it fits.
I always like your diagnostics,very proffesional, only to correct that the mesurements in the emissions are in millions per "cubic" centimiter(cm3), not in squere centimiter(cm2)
Hi Dan, I, too, have a similar problem ie. the fault code that I got was U029A- lost communication with the Hybrid Battery Pack service module. Would it be similar to what is explained in your clip?
I'd really like to see what the particle counter has to say while the DPF burns the particles in one of its cleaning cycles. It happened to me to drive my motorcycle behind few new cars that were (supposedly) doing the cleaning and I was suffocating...
@@lordjaashin Well, unless they were all "new cars - meaning new models - with engine destroyed", they started to emit white smoke with a bad smell (not like a burning oil car) for some time, and stopped after like 2/3 minutes. Like this: ruclips.net/video/T7XjBa_9og0/видео.html or like this: ruclips.net/video/7qIh5PqeVqM/видео.html
@@AlessandroGenTLe tbf that doesn't look like normal dpf regen. theres white smoke coming out from the front wheel arch in first video. DPF regen doesn't cause that. AFAIK DPF regen occur at 2.5k rpm at highway speeds in diesel cars. don't know if that is the case with gen 1 DPF cars. second one is forced DPF regen which doesn't happen in everyday driving conditions. they are wantonly revving their cars to clog up the DPF filter so that the ECU is forced to burn off the soot to reduce Exhaust pressure even though the car is stationary. this causes incomplete combustion of excessive diesel fuel producing more soot and nasty exhaust. so unless you revv your diesel like a maniac while stationary or in stop n go traffic you'll never face this situation in your daily driving.
@@lordjaashin Don't know mate, it happened with a BMW X3 while driving down a hillside big road here in Italy, one of those roads where you can drive at 90km/h constant speed. And it happened again with a VW Passat (if I remember right) on another "highway-style" road to the MXP airport... About the video with the Opel: a standing still car smoking out just needs a 1km/h wind coming from the back to looks like it's smoking from below the car ;)
A question for Diagnose Dan. Wouldn't a car with the DPF removed have an accumulation of black soot on the inside of the pipe? I've noticed all of the diesel vehicles here in the US with DPFs have 'squeaky clean' tailpipes. In fact we found a truck with a cracked DPF by seeing the sooty tailpipe. BTW, keep up the good work. You are an excellent teacher!
Soot are the larger particles we can actually see with the naked eye. The smaller particles that we don't see are even more dangerous for our health. A DPF filters Both. Alot of times when a DPF is removed the Car is also tuned, that is the main cause for the black smoke
The battery cooling blower fan on my Prius was full of white lint that restricted air flow which I believe caused premature battery failure. Disassembly of the battery cooling system was complex compared to the Lexus. I'm surprised that when the battery was replaced the technician didn't think to check for a restriction in the cooling system.
@@Diagnosedan quick question , in your experience would you say Japanese cars ( here I am referring to ICE. Hybrid, and electric) are more electronic reliable than the German group cars.
Hi dan it's not hard to understand if you got a good explanation for the faulty ... Thx for the video.. tis een zeer goeie video zoals altijd bedankt hé 😉👌
Good to see your video again,Dan. So should I encounter this particular code,P3105, I am going to right away replace those cooling fans..without diagnosing it
In the old days a 1uf cap across supply and maybe a 10 nf to make sure hi and low frequency grounded out. Surely the fans are shape poled motors . I like to stop vid and see if you fix problem the way I would try to find fault . This time I didn't as I would of warmed control unit and froze to no avail 😁
Another great video DAN ...A bulletin is generally the result of some poor guy spending hours / days actually diagnoising the fault so others do not have too

The way they came to a stop they looked like brushless PM motors. Like the ones in your computer. Can't argue that the fans did it but I'm not certain there are brushes in there. Manf would not want anything that sparks near the batteries. Would love to tear them apart and see if they have any filtering on the supply wires.
@@OldePhart Could be some faulty condensators in the blower motors if there's a filter inside ? No idea why the motors else would give the noise on the line......
Excellent video..
A twist from the other side...
The software application have seen the problem and given us a DTC. If the application is well developed it has a ringbuffer in form of a transient recorder that records pre and post that event (DTC) automatically. Sometimes in some systems(trains) you can on top of it set the event in the software algoritm as a trigger and choose a couple of signals to be recorded (pre and post) that you suspect. But thoose functions is buried deeper inside the manufacturers system. If the systems are designed as I am mentioning you would not need to hook up a scoope to solve the problem. The surrounding information is collected and sent up to the cloud and you can see it there. But that is on swedish trainmanagement system and not on cars.
One proper guy, one proper channel, quality as always. DiagnoseDAAAN!!
Thanks!
@@Diagnosedan Very welcome!
Love the bloopers. One may always wonder how difficult it is to make a good YT video. It doesn't look as easy as you make it. Dan does it again!
I enjoy watching you and I can’t help but learn something.
Great video Dan thanks for sharing!! Now what went bad on the old fans? It’s interesting how they bring down the network while they are still spinning fine!!!
I'll do an update when i've examined the old fans
@@Diagnosedan that's awesome I'm looking forward to the update!!
Me too!
@@Diagnosedan do you have an update? Are these 12 volt fans?
What do you think inside the fan motors is disrupting the signal? Because I’m thinking they’re simple DC motors just like a cabin blower motor… Wear on the motor causing higher amperage? It would’ve been really cool if you had tested the amperage on the newer motors compared to the old!
Are they variable speed motors,do they have a built in resistor that controls the speed of the fan?
Thanks for the video! 👍
I'll do an update when i've examined the old fans
It looks like theyre not balanced really well causing vibration and premature wear, would like to hear why they failed
Thank you so much for generously sharing your time and expertise
Proving the old adage that good information is beyond price.I'm retired from that job, but back in the day I wrote service and troubleshooting manuals for equipment almost as complicated - ours had fibre optic communications so immune from that nasty electrical noise. Thus I appreciate the &*)) out of good technical bulletins. Glad to see you looking hale and active.
Thanks for the comment it's appriciated. You must have been writing those manuals for something to do with Audio and Video. Fiber optic is also used in cars mostly for the entertainment system.
@@Diagnosedan Actually, it was bank proof equipment that read the magnetic encoding of the MICR line, and sorted checks in to pockets for distribution to other banks. 500 documents a minute down the track with auto-feeder, read, encode, endorse and microfilming functions plus up to five 4-pocket modules with attached printers. You think your customers are fussy - bankers can be far worse about the read rates for garbage MICR printing.
great video, i missed checking the old fans and see what is wrong there :)
I'll do an update when i've examined the old fans
Dan you are worth every penny.
Please tell my Wife🤣
Man's got a completely separate hand wave for every syllable! :)
🤣🤣👍
Hello Dan from Hoboken New Jersey USA.
Love your videos Dan, so happy to see a new episode.
Keep up the good work.
Thank! That's appriciated
always is nice to understand new things the easy way just like you Dan do - appreciate your effort for helping us in our learning process - greetings from Caracas Venezuela to you, to your son and daughter - really like watching them helping you in your shop -
Thanks Mateo
Hi Dan, interesting stuff on the DPF. Do you know what sort of measurements you get when a car is doing a regen cycle? Is it still clean?
It should be, maybe we can do an experiment in another video
How does the scan tool turn the fans on and off, if the fans cause a no communication fault? I hope that makes sense... during the times when the network had all that static from the fans, how did the scan tool turn the fans off?
Ha good point. The fans are also connected directly to the Hybrid control unit with a direct single wire.
The only thing affected was the can comm. between the Hybrid control unit and the Battery contro unit. Communicating with the Hybrid control unit was still possible
Those squentimetres are rarely used these days but I fully understand the communication between the brain and mouth can get overloaded at times.
Also seeing the particulate instrument at work is scary information.
Such a useful info!
Great personality makes it even more greater! Thank you!
Interesting one Dan. But CAN BUS is supposed to compensate for external noise on the signal. I might have missed this if I listened to network theory! Also, no single fan was causing the issue? I wished you had diagnosed one of the bad fans to see why it was causing so much noise. But thanks again for a great video. Hybrid issues are only going to become more common.
Fantastic job boom! U are a professional in diagnostics thank ( DD). I love your video intro. Habib Auto all the way from Ghana West Africa
Thanks!
Dan has done it again, and it's always a delight! Thanks!
Thanks Brian
Dan, the last time I used a particle counter was in a clean room for semiconductor manufacturing, never thought of seeing one used for diesel exhaust checking. What about using some high frequency filter caps for fan motors to get rid of noise? Great video, clone yourself, not to many techs would take the time to properly diagnose the problem correctly.
Thanks for the feedback Alfred. I'll examine those fans on a rainy Day to see what's wrong with them
thank you my friend. The contents you provide are great but I have a question what kind of this device do you use and what do you recommend to use for Japanese and German cars to check it well
Launch or Autel
Awesome job thank you.... Mine intermittent also,... only occurred during high load... Fast speed, climbing hill. Etc. Fans were under stress. Since fans still worked, and appeared to be working up to speed, do you think they were slightly out of spec. To throw the code and disrupt the wave form??
Wonder if a new brush set would take care of the problem or perhaps a power feed circuit from the controller to the fan assemblies that has better signal filtering. I'm assuming that a cleaning of the commutator rings and new brush set would have solved the problem if they were replaceable. Increased arcing at the brush-commutator contact is probably the source of the noise that's finding its way back to the hybrid battery controller and giving it fits.
brilliant work Sir, I really enjoy your videos. thanks for sharing. best wishes from NZ
Thanks Dave
@@Diagnosedan your welcome Dan. I love your clips. always well done. cheers NZ
I always like your diagnostics,very proffesional, only to correct that the mesurements in the emissions are in millions per "cubic" centimiter(cm3), not in squere centimiter(cm2)
O did i say that? 🤦 You are right! Thanks for pointing that out!
Hi Dan,
I, too, have a similar problem ie. the fault code that I got was U029A- lost communication with the Hybrid Battery Pack service module. Would it be similar to what is explained in your clip?
Me too
I'd really like to see what the particle counter has to say while the DPF burns the particles in one of its cleaning cycles. It happened to me to drive my motorcycle behind few new cars that were (supposedly) doing the cleaning and I was suffocating...
how can you know that a car in front of you on the road is cleaning its DPF?
@@lordjaashin Well, unless they were all "new cars - meaning new models - with engine destroyed", they started to emit white smoke with a bad smell (not like a burning oil car) for some time, and stopped after like 2/3 minutes. Like this: ruclips.net/video/T7XjBa_9og0/видео.html or like this: ruclips.net/video/7qIh5PqeVqM/видео.html
@@AlessandroGenTLe tbf that doesn't look like normal dpf regen. theres white smoke coming out from the front wheel arch in first video. DPF regen doesn't cause that. AFAIK DPF regen occur at 2.5k rpm at highway speeds in diesel cars. don't know if that is the case with gen 1 DPF cars.
second one is forced DPF regen which doesn't happen in everyday driving conditions. they are wantonly revving their cars to clog up the DPF filter so that the ECU is forced to burn off the soot to reduce Exhaust pressure even though the car is stationary. this causes incomplete combustion of excessive diesel fuel producing more soot and nasty exhaust. so unless you revv your diesel like a maniac while stationary or in stop n go traffic you'll never face this situation in your daily driving.
@@lordjaashin Don't know mate, it happened with a BMW X3 while driving down a hillside big road here in Italy, one of those roads where you can drive at 90km/h constant speed. And it happened again with a VW Passat (if I remember right) on another "highway-style" road to the MXP airport... About the video with the Opel: a standing still car smoking out just needs a 1km/h wind coming from the back to looks like it's smoking from below the car ;)
that's a good point you've raised
That DPF side track was awesome!
Thank you!
Amazing content. Thanks Dan we all need to help you . You are a great help to the independent trade. A real resource
Amazing as always. We SO need this in the US!
Thanks for taking the time to leave a comment it's appriciated 👍
Great video. Very informative. I usually don’t work on hybrid cars but good information to know.
Thanks Steve!
Another excellent presentation and diagnosis.
A question for Diagnose Dan. Wouldn't a car with the DPF removed have an accumulation of black soot on the inside of the pipe? I've noticed all of the diesel vehicles here in the US with DPFs have 'squeaky clean' tailpipes. In fact we found a truck with a cracked DPF by seeing the sooty tailpipe. BTW, keep up the good work. You are an excellent teacher!
Soot are the larger particles we can actually see with the naked eye. The smaller particles that we don't see are even more dangerous for our health. A DPF filters Both. Alot of times when a DPF is removed the Car is also tuned, that is the main cause for the black smoke
Hi I have recently discovered you.. And watching your videos....its great please keep on making such videos😄
Hello Dan Your videos are interesting and professional and with all that you are also funny, thank you.
Thank you!
Awesome!!! Dan is such a great teacher. Thanks 👍😊
Good to see some battery based diagnostics, bring on the EVs!
I've made quite a few already!
The battery cooling blower fan on my Prius was full of white lint that restricted air flow which I believe caused premature battery failure.
Disassembly of the battery cooling system was complex compared to the Lexus.
I'm surprised that when the battery was replaced the technician didn't think to check for a restriction in the cooling system.
Mooie diagnose weer Dan, en wel makkelijk bij te komen gelukkig
Dat dan weer wel.....😁
Watching from Zambia 🇿🇲
Great! Thanks for watching
DearDanno,As always you have captured my attention.... Great Vid.
Thanks Dave
Thanks again Dan for the knowledge very useful keep up the great work love the technical stuff 👍🦘
Thanks Damien
Thanks Dan! Can’t wait to check out the new video!
Thanks for watching
you have the best content in your videos very educated keep up the great job Dan!
That's great to hear! Thanks
Sie sind gute Mann und haben viel Ahnung.
Very informative video. Thank you.
Nice to see you are finally doing videos using Japanese cars then the usual German car group. 👍
Thanks!
@@Diagnosedan quick question , in your experience would you say Japanese cars ( here I am referring to ICE. Hybrid, and electric) are more electronic reliable than the German group cars.
Hi dan it's not hard to understand if you got a good explanation for the faulty ... Thx for the video.. tis een zeer goeie video zoals altijd bedankt hé 😉👌
Graag gedaan!
Great video Dan. But what was wrong with the fans? Worn commutators producing RFI?
Good to see your video again,Dan. So should I encounter this particular code,P3105, I am going to right away replace those cooling fans..without diagnosing it
What's the reason the fans caused the communication error?
Great diagnosis. Any idea what deteriorated in the fan to cause the "noise" and communication failure?
I'll examine the old fans and i'll do an update
In the old days a 1uf cap across supply and maybe a 10 nf to make sure hi and low frequency grounded out. Surely the fans are shape poled motors . I like to stop vid and see if you fix problem the way I would try to find fault . This time I didn't as I would of warmed control unit and froze to no avail 😁
Thanks for watching Ian👍
Another great video DAN ...A bulletin is generally the result of some poor guy spending hours / days actually diagnoising the fault so others do not have too
I know i make alot of those Bulletins myself🤣
