Parasitic draws caused by network faults are the most challeging and time consuming faults to find. But you nailed it like a boss! 👏

My pappy said, "Son, you're gonna' drive me to drinkin' If you don't stop drivin' that Hot Rod Lincoln" - Commander Cody

The really interesting twist here is that the parasitic draw was cased by a component that uses hardly any energy itself - the draw was from keeping all the other things awake. Fascinating.

Wow - that was an epic diagnosis! It would be nice if brands implemented a 'force sleep' mode as a two way test so you don't have to wait 20 minutes to continue diagnosis. Thanks, Ivan.

I have been in the business for many years (retired now) and after watching the whole video parts 1 and 2 I am glad I am retired. You are amazing , more important is your flawless diagnostic process. Impressed to say the least. My last Parasitic draw was on a BMW 530d and after that I retired, yes I found it .Boy do I wish I had a scope in my day , thank you sir

Navy aircraft design..specifically the P3A orion. Systems were designed to make sure FLIGHT ESSENTIAL ELECTRONICS were able to survive in case of damage or fire. Crew members had to memorize all the circuit breakers inside the " tube" or interior fuselage. We had to know how to disable systems that were shorting the main bus bars or in case any electronic equipment was smoking or on fire. Very complicated indeed..but the engineers made sure we could keep the engines turning and get the landing gear down with catastrophic electronic failures. I wish car engineers would think like that. The rtm seems like an essential control, it should not have been buried like it was, and its loss should not disable the car. All that money spent on 30 modules, and they couldn't build in one more redundant back up to ensure the car could limp somewhere

You are so patient and thorough in your diagnosis. I'm 63 and have learned so much from your videos. Thanks for sharing your knowledge.

I like my (reliable) 20 year old Toyota more every day. Thanks for the reminder as to why.

At 16:03 mark you said " too many modules, is your head spinning?" YES..IT WAS ALREADY SPINNING IN PART ONE. this is job is for advanced electrical troubleshooters only.

Be careful when reprogramming the new module, as a tech at Mercedes i've seen a few times where the scanner wants the old module installed first and it copies the bad programming which winds up causing the same issue on the new module. sometimes we are able to get away with performing an Initial Startup of the faulty module and it fixes the problem without having to be replaced. Great Diag!

Unbelievable diagnosis. The thing about diagnosing vehicles is you have to have persistence. Many just don't have the will power to keep thinking and moving forward so they give up and usually fire the parts cannon. There are pressures on technicians to make hours and they can't win on a scenario like this so they give up and move on or order parts to move the vehicle out of the shop. But each time you find and fix one of these, it adds to your knowledge bank and helps you on the next one. Even Josiah learned a ton during this one and he will be better the next time he has a similar situation.

I have to say. I feel that electrical diagnostics ending up with a problematic, yet still functioning control module, can be some of the toughest electrical problems to find. This case study was a perfect example of that. The module in question here, for the most part, is still functioning. Just not exactly as intended. The shop I work for, everything is fast paced. So, it's pretty rare that I get the time to really dig deep into jobs like this. Plus, I usually don't have access to some of the tech I would need. So, it's a real pleasure for me to watch people like Ivan, roll up his steeves and get busy. Amazing detective work there Ivan! I can't wait to see the conclusion.

There is no better channel IMHO on automotive diagnostics then pine hollow. Thank you for these well informed documentative videos Ivan.

Wow. What a saga. Insane that a corrupted module keeps a series of modules awake and drawing some amperage. This is why you’re the master Ivan. You’re a blessing to so many diagnosticians my man. Sharing your wisdom an experience has exponential impact.

That was a complicated parasitic draw diagnosis Ivan! It's crazy how these newer vehicles are too dependent on modules that you literally wont be able to start it if one of the modules were bypassed. Looking forward to the last video for this vehicle.. thanks for again taking us along the process. Cheers!

it was like a 15 round boxing match against that car , a real technical knock out you had to do to win , great job Ivan !

I need a nap after watching that marathon 🤣🤣🤣 great video 👍👍

whats right is whats left when everything else you do is wrong, great notes you never got lost or going in circles, a problem solving template for all

Glad i am retired from working on cars for a living, they are getting more & more complicated with the amount of electrical crap they fit on them, but total respect to you for your patience & determination to not be defeated by it.

The hardest parasidic draw you've ever done and the best one we've seen, diagnosis was great to watch!

Your supreme confidence in your method and determination to see the job through served you well yet again in this brutal case study.

Wow.... This is the reason why former president Mr.Donalp Trump will watch PHAD on his free time , absolutely spot on and no guessing. How to gain knowledge like you Mr Ivan???

That electrical system is way too complex! I mean seriously, if it takes that long to diagnose the issue, the car isn't worth it! Whatever happened to putting the key in the ignition and turning it to start the vehicle? It's all about adding enough crap and tying it together to make repair (after the warranty has expired) unrealistic! If you ask me, it's a nice looking piece of garbage! And I know the FORD isn't the only manufacturer that ties multiple modules together! Amazing diagnosis, Ivan! 👍

I know from my time at bmw when individual modules all connected by can networks peaked at 68 (a lot of current every time you wake the car up), it was a fun time chasing current draws. Fibre optic, can high, can low, byte flight, i-can, lin bus, k-can, MOST etc etc lol. We found that in most cases for bmw. It was a control unit waking up and trying to communicate, causing a draw. Even better than this, everything would work faultlessly. Then they would often do it in the middle of the night. So we would have to set up long term oscilloscope track over night to catch it. I know your method is usually the most effective. We found that with absolutely everything interconnected and monitoring. Our trusted way was to trace the communication as you did but then (with the luxury of the cars full spec and factory wiring diagrams at our disposal) disconnect directly at the module one at a time methodically. If you pulled power (cutting it off at the head) as you did. Often the tail would wag and cause other parts of the car to react. Where as if you isolate the module, it would log a code but just be lost to the network. Not affecting anything else. Except the MOST obviously because it is a fiber optic loop in series. We would have to install a fiber optic loop out of the chosen module before putting the car to sleep. The real kicker is when you move into the module that you found at fault. You would actually find no physical fault. But with the advent of key-less ignition and entry, meant owners in the habit of leaving their car secure in their garage/house but unlocked. So because of software. The car would take 45min to and hour to go to sleep but then realise hours later, "hey, I'm still unlocked. Maybe I should stay ready". Wake up to look for the key. Or worse, the customer would leave their keys near the door or in their pocket and walk past the garage. Then because of proximity, constantly pinging each other. "Wake up, they're back!". Haha So then we had to re-educate our customers to yet another function, that they must lock their car always, even in their own garage. I will also say. As soon as this era haled in. We recommended that owners buy a quality smart charger accross the board due to the power demand and most people only driving small trips. As always, love the content Ivan!

This is just amazing...! Ivan, absolute insanity... I am recalling a good friend of mine whom was a factory trained GM technician..., telling me (1980-90’s time frame) that most of the vehicle(s) that came in for a problem was an electrical related issue... He referred to them as a “F.R.E.D.,” (f’ing ridiculous electrical device) problem... He also made not that GM had, at one point (to cut down on weight=fuel economy & overhead=the almighty dollar), gone to aluminum wiring in their autos..., for a couple of years, but then went back to copper..., as they were having some many problems related to using the aluminum wiring... Great video series, Thank you sir.

Honestly Ivan. I really enjoy watching you work. Your methodical, logical, knowledgeable aptitude is superb. Folks are very fortunate to have your services available in your trade area. I`m not a tech, but I have learned a lot from watching you. Thank you.

I'm not Worthy!!, I'm not Worthy!!.Your Awesome!! I enjoy very much your videos. Keep it up. ✌👍!!

What an over complicated monster. Do vehicles really need to be that elaborate? That was a mind bender Ivan, you are the man! Great Job!😊

This is crazy. The future of electrical diagnosis looks like it'll be an expensive endeavour for the customer. I can see now why it's taking such a long time to diagnose. Great vid Ivan. You did have my head spinning a couple of times with all the module interactions. Lots of folks entertaining the purchase of new cars might want to watch this and they'll have a better sence of what a technician goes through and why it's so expensive.

That fault does have a name, I work for a controls company and play with CAN type busses. Its called a babbling node, it grabs the wire and wont let go increasing network traffic and causing lots of headaches. It does usually mean a bad part. The fact it wont allow a firmware flash again usually means the part is bad. Nice job on the troubleshooting, you hung in there on that one. Network issues are always a pain! :)

Holy mackerel, 37 fuses linked to the BCM?, nuts I tell 'ya!, no way the dealership would have anyone on staff able to do this type of diagnosis!.

Very nice, Ivan. Very nice. Perseverance, determination, and careful documentation pay off! Another well done, series. I wonder how long it would have taken the dealership to solve--sorry, I meant how many modules would the dealership swap out before finally getting lucky.

You may have just edged out Eric O as the master troubleshooter. Impressive!

WOW!! This just solidifies my line of thinking that I will never buy another vehicle built after 2006 (preferably none after '72, lol) for as long as I live! If this were mine I probably would've lost it and tossed a map torch inside with the flame locked on! MAN, what a nightmare! They've got modules for modules, lol! Ridiculous engineering here. They go through all this complexity, and STILL use low-bidder garbage components. Just mind-blowing!! Impressive willpower, Ivan. I don't think I could've succeeded on this one without quitting in utter frustration! Nice work!

That is why this channel is a must have. U will never get this kind of guidance anywhere else. The hot shot Ford techs will know how to fix this car, maybe. But they will know because the dealer hotline told them we have a high failure rate on these modules, not because they got their scopes out and did the proper analysis. And that will only b at dealers that have the really good techs. Not many have them. I wonder if Brian at Ford tech makeuloco has seen this. Thank u Ivan for making this content possible!!!

They train you at BMW STEP for those type of draws. Apparently the doors keyless entry would keep the vehicles awake since they know which door you are approching and the touch sensitive handles would mess up. These complicated security systems are why carjacking is way up, because thieves can't steal them when your away. There's a great investigative report from Michael K Williams on vice that you can watch on KZfaq. He also reports on illegal guns and similar street crimes by talking to the criminals.

Ivan. We, your followers, are tired of giving you these accolade's - BUT! You've earned ALL of them and many more. Thanks for the ride - I don't know how you push on like you do. My hat is off once again, to you. Thanks

This was totally awesome! I think it would be accurate to say few would have hung in there long enough to get to the answer! Way to be tenacious and follow through! That list of modules in your notebook was jaw dropping-makes me glad I drive a 92 Ford OBS with a mechanical diesel! Nice to see you and Josiah working together again and I am very much looking forward to part 3! Awesome job and video as always!

Hope you were not too stressed out with this job. Crazy problem! Looking forward to part 3.

I used to wonder why you took copious notes on each case study, now I know why😣 Excellent diagnosis

Nice work. Even if the programming procedure worked on the old module I would have replaced it. Working with micro controllers I have found that corruption is a sign of decay and future failure is most likely. I enjoyed parts one and two and look forward to three. Also I appreciate you explaining how you bill for your work in the past. It appears that cars and trucks are continuing to subdivide into specialties like the people movers I work on which require five highly skilled crafts on site to keep them running with an additional group off site for support. Even in my craft we have specialists for subsystems. One thing is given, it is never boring. Frustrating at times but never boring. Cheers.

Had the same type of issue recently on a 2012 Dodge Journey SXT. Draw from the BCM, Took me forever to figure out! It ended up being the intelligent battery sensor(which in my case was a LIN style sensor) it was somehow waking up the BCM and subsequently several other modules in the car. Great Video!

There’s a hidden place in the glove box, center console or under the cup holder rubber that you can put the fob and the car will start. It’s incase the battery is dead in the fob :)

Some 2015 Lincoln MKC vehicles may exhibit a dead battery due to welcome lighting (display/radio/lighting etc) staying on or cycling on and off when the keyfob is left within detection range of the vehicle. If the vehicle is built before 8120/2014 reprogram the Radio Transceiver Module (RTM) to the latest level using IDS version 92.05 or higher, and continue to monitor oasis for updates. Use applicable 12651 D labor operations in section 10 of the SLTS manual and use causal part 15K602. Engineering is currently investigating this condition. To prevent battery discharge, the welcome lights function can be turned off through the cluster, or the key may need to be moved further from the vehicle when locked. If the vehicle is built on or before 8/20/2014 reprogram the RTM and the BCM to the latest level using IDS or Ford J2534 version 95.01or higher. If the vehicle was built on 8/21/2014 and through 1/31/2015, reprogram only the BCM to the latest level using version 95.01 or higher. Make sure you are connected to the internet when entering module programming to obtain the latest updates.

Very interesting diagnosis. Something you may want to add to your diagnostic kit for these new cars with key fobs that do presence detection is a faraday bag or box so you can quickly switch the fob from nearby (out of the bag/box) to far away (inside the closed bag/box). A simple metal box (such as a toolbox) would work, or a repurposed ESD-safe bag (like toll transponders or some PC parts come in). And of course you can buy something online specifically for key fobs

Ditto to many of these comments. Great video. Your content never ceases to deliver.I pretty much drop everything every time a new one drops. This one was fantastic!

Ivan, your patience is astounding! Not my brand of choice... glad you confirmed it. Happy New Year!

Forgive me for laughing when you said "it's either the RTM or the sync module". It might as well have a -kitchen- "sink" module.

Great video Ivan ! A current draw caused by active modules makes diagnosis much deeper and more time consuming when the initial approach is to look for a static current draw from component failure or shorted wiring. Enjoyed that. Thanks for sharing. 😄

My taking here with this many module. First look at the networks if still activity after good 30 min. Attack that problem. If module wont go sleep final result is current draw. Good approach. Newer cars getting more complicated to fix specially this one.

I haven't seen you get stumped yet.. it is fascinating to watch you work.. I can say I've learned a few things from you.. thanks

Determination and methodical procedures writing things down to keep your mind focussed all comes to fruition in the end . Another awesome case study looking forward to part 3.

Incredible work Ivan , well done

Not exactly related but Ford for years had parasitic draws from amps and phone transeivers when they were first installed from the factory (not aftermarket insall). very little info available at the time. Great job Ivan.

Your the one of the best also sma and scanner Danner , 👏👏👏👏👏👏👏

So happy to see that now you zero the amp clamp using the recommended procedure.

What a diagnosis. Hats off Ivan

next time put a battery disconnect switch inside the cab,, when they get to work they can switch it off, when they get home switch it off and plug in battery charger, they can pretend they have an electric car and really impress the neigbors,, lol

Bernie would be proud of you two! Fascinating case study. Thanks guys!

Wow great diagnosis bro, I see that many of us technicians and mechanics are still learning from you. And this is the first time I see a parasitic draw from a bus module like you diagnose.thanks a lot Ivan.

Wow...next time I'm bringing some popcorn👍

Wow, this’s really cool diagnostic 👍🏼

Awesome!!...as usual...you're diagnostics are cool!!👍😎

Wow. Very impressive diagnosis.

Great diagnosis very thorough! These videos have taught me a lot about looking into electrical issues and i just found your channel a month ago.

It was good to see you struggle a little for once. And thanks to you we all learned something here. Cheerz

thank you for improving our diagnoses great job

Awesome job, great video production as well as diagnosing :)

Awesome diag, you're setting the standard for these types of diag/repairs. I can only imagine what the dealership would have done. Thanks for the video.

Absolutely brilliant diagnosis!!

I am not sure why everybody here is so shocked about the abundance of electronics in vehicles these days. This has been going on for many many years now so not sure why the surprise. Get on with the times and keep expanding your knowledge base. Expand your tool kit with modern diagnostic equipment as well. If you want to be competitive you need to keep up with the technological advancements. No point in whining. I am sure back in the day when carburated vehicles were the norm, mechanics were crying about the introduction of the fuel injection... and look now nobody even thinks twice about it. Every device in our daily lives is becoming more complex for better or for worse, but there is no stopping it so get on with the program lads. :D

So. Many. Modules. Unreal. I am convinced to keep my 2004 Highlander forever, I don't want anything more complex, ever.

Have to say.. great job Ivan! So interesting watching your diagnosis path.. and finally nail it. Nice job!

My second comment on this: It does make me wonder how many parts canons have been fired by just unplugging fuses, finding a fuse that the high current goes through, just replacing modules on that power leg to find that didn't fix it.. One would have never found the actual cause that way. Very clever to monitor all can buses for activity. Thanks again for the education, Ivan.

Very good diagnosis. Gotta love a scope.

Really amazing diagnostics Ivan, I applaud your persistence! :-)

Yes! Part 2,,, Thanks!!! Your are one of the Best at auto diagnostics!!! Love your content & skill!!!

Impressive determination, both showing patience and courage! Professional diagnostics. Lucky it wasn't a intermittent fault in the module.

Wow!, well diagnosed and traced down to the faulty component. Top work Ivan!.

Definitely a tough nut Ivan, great work 👌. Excellent diagnosis and prognosis, thanks for sharing.

Fantastic process and very inspiring to hold on. Think clear and work it step by step.

Loved this diag. Thanks for sharing!

Yet again - excellent troubleshooting methodology example.. Many thanks & great work

Your the man!! Great job! Love your dedication to finding the root cause. Learning so much from you.

Very good job what a pain why can't things be like they used to be

Fantastic how you bite in these kind of problems🤙🏼 Fantastic to see Regards from Holland Europe😎

Once again proves the need of a good scope to diagnose today's cars thoroughly.

You da man Ivan !! I bet it was awesome feeling to go through that and finally find it !!

Good solid daigs. Nice to see positive tenacity at work :)

This has to be your pinnacle of a parasitic draw. Ivan, you could put inspector Clouseau to shame. I would imagine anyone owning this vehicle with a similar problem, you may save them tons of time and money with this video. I am so glad I DO NOT own anything made by FORD. I had one years ago...NEVER EVER again. I cannot express how impressed I am with your tenacity to never quit. Great Job man....seriously.👍🇨🇦

Insane! Great diagnosis Ivan.

Fantastic job there Ivan!

well done, the pair of you looked shell-shocked😆.. Excellent work Ivan, i hope he fead you well..👍🏻

Great end result keep the amazing content coming 👏 👍 👌

Awesome Ivan you definitely earned your diagnostic time on that one and you collected tons of notes so if you ever come across anything remotely close to this problem on another Ford you will be ahead of the game!! 👍👍👍👍👍👍👍👍👍👍👍👍👍

Amazing work glad you got to the bottom of it a total master class in diagnostic and the obd scanner in this case was a minor help

That was quite a wild ride.

Some of these draws in these new cars can get crazy. A couple of years ago I had a Chrysler van that had a small pinch in the rear sliding door harness that went pretty much just like this diagnosis. You’d think their programming would have some kind of pattern recognition to ignore something keeping everything awake after a certain point.
