Dedication to your craft at its absolute finest. Ivan it is because of techs like you that makes watching you a joy

For cases like this it would be really interesting to use pico serial decoding to get the CAN ID of that first message that appears on wakeup. Once you have the message ID, you could find out which module that belongs to by just monitoring the network in a normal ignition on state, and pulling fuses for each module on the network until the ID of interest disappears. For this to work you would need to sample the network at a high enough rate to be able to decode it, and also use the very first message only, as once one module has started transmitting it may wake other modules as well.

I was just coming to write your comment as I downloaded the pico data and see that the sample rate isn't enough to do serial decode. A parallel suggestion would be that there are purpose-built CAN decoders/encoders that could be connected to the network to do this capture a little more simply if you want the serial and not needing the waveform. There's some information over on redit's CarHacking subredit in a pinned post and sidebar.

For techs 60 yrs and up. Do you all find this as overwhelming as I do. I’ve been at this since 1972 before electronic ignition, fuel injection , computers and networks. I’ve seen the expansion of electronics. But using this many networks just blows my 68 yr old mind. I enjoy watching Ivan tackle these jobs but I realize there has to be a limit to how many techs understand these systems. I’ve seen the blank looks in class on a lot easier systems over the years. I’ve seen the number of cars Ivan tackles that dealer techs can’t figure out with their overwhelming info advantage. I wont be surprised to hear there are a lot who don’t comprehend everything he does. I’m not too proud to admit I don’t. I consider myself in the top 10% of techs on electrical diagnostic skills but see that I’m falling behind since I retired 6 yrs ago. Just interested in what you older guys think. The young 40 and less can chime in too. I won’t be offended. Del

Create one such as trunk light and go through motions of tracking it down. Very few are cut and dried. Good luck.

I love watching you diagnose. I feel smarter and have learned a lot

Wow, Ivan that was really cool diagnosis of the parasitic draw!! Glad you had the experience to find out right down to brass tacks!!! Nice job Ivan. Let's see what happens in part 2.. i bet it is the cluster or the radio problem, as i remember your past videos!

Every 1 minute & 40 seconds! No wonder the battery goes dead! Part 2 hopefully has the answer to what it is! Thanks Ivan! Very interesting for sure!

Customer complaint proved! Now the challenge is finding which module or modules awaken and hopefully the cause. It is a bummer when the only thing you find is the module that awakens and not what actually awakens the module. I appreciate the module could be faulty, however identifying the module is only one part of the diagnosis. the other is determining if it is a faulty module or if it is an external issue that is buried in the depths of the vehicle or wiring loom somewhere, either OEM or worse still, aftermarket. Either way, confirming the root cause before calling the module could be an expensive bugger. I am looking forward to part 2.

Very interesting case, if not annoying for being intermittent! Thought process of a real Sherlock Holmes, Ivan 🙂Like most network problems, impossible to have a clue without a scope. I find it maybe telling, that there is only a slight increase in current, before it triggers an event that wakes the network. If it weren't regular like a clock, I would say a parasitic current somewhere (green crusties or water intrusion), but being so regular, it must be a module on its own. Curious to see which one is the culprit - let Part 2 begin soon 🙂

Thank you Ivan for showing how valuable a scope can be in helping track down misbehaving modules like this. Knowing the info you just gathered from the scope will seriously cut down the list of suspects in this case study. Your right though. Without the help of the scope, a problem like this could take days, or even weeks to hopefully discover the problem. And would most likely allude someone like me from ever finding it. I can't wait to see what you find in part 2.

Thanks Ivan for sharing your knowledge and wisdom. That is what makes a true loving human being. Peace. Scott.

You do great step by step diag never forgetting to start with the basics. 👍🏾

Hi Ivan , part 2 ASAP please, can't wait. Many thanks super interesting problem.

Oscilloscopes are awesome tools. I was a computer software engineer (retiired now), and for much of my career, I kept an actual old fashion analog oscilloscope on the workbench next to my desk along with a variable power supply, a digital multimeter, and a signal generator. Those were the basic tools of an electronics bench technician in the 1970s-90s, but I found that o-scope useful for all sorts of realtime computer software debugging, as I was working on IO device drivers much of my career.

Hopefully the wiring diagram will be helpful in locating the problem module. Taking the problem CAN network out from the gateway loop or taking it apart also called isolation is the best way to find the problem, IF you can do that. THIS problem should be "Very Interesting!" Very much looking forward to part 2 ! !

"...four channel scope!" Beautifully detailed capture of the event. Well done Ivan!

3 amps for 10 seconds every 100 seconds is only 0.3 amps average. Your typical car battery is at least 50 amp-hours so it should hold out for at least 100 hours. So it should not be dying overnight, more like after 4 days or so. Or maybe the stress of losing 1/4 of the charge and recharging that much the next day, maybe that wore out or dried up the battery. Waiting for part 2!!

@@dizzy2020 I understand that one can't describe a battery with just one number, the power curve is going to be a bit .... curved. But not to the extent that a 300 milliamp load will discharge a battery "overnight"! That's over ten times the expected discharge rate. But then on the other hand, if the battery has been repeatedly discharged to zero many times, it's amp-hour capacity can be greatly diminished, even if it's relatively new. Long ago my father had a mercury with a tit-switch controlling the trunk light. If you parked the car on a hill, facing down, the trunk light would go on and discharge the battery quite a bit overnight, leading to eventual battery failure.

Just thought I would let you know my favorite tool to find parasitic draws in general is a thermal camera. Found a P.A.T.S. module awake in a Lincoln Navigator last time I used it and it was behind the dash. Found in about 20 seconds.

Ivan, you tend to focus on the fact that Ford vehicles take extended time to go to sleep. I bought my Mercury when it had 92 miles on it and was being used as a demonstrator. I got the car home and was admiring my new car (I have grown up since then!) and suddenly the air compressor started (it is equipped with rear-air-suspension.) I talked to a technician at the dealership and he told me that air compressor can run up to 29 minutes after the ignition has been cycled. That car is 27 years old. So, I can conclude that has been going on for many years. Great video!

You are a genius to diagnose this parasitic draw. Similar to looking for the proverbial needle in a haystack. You should take bets on which module(s) are the culprit.

Ran across your video - Well done - I have 2016 MKX that is experience a parasitic draw as well - Thinking it is having the same issue - Telematic Control Module - I believe that module is 3G based and with the U.S. shutting down the 3G network in 2021 I am thinking that module is continually trying to connect to the network and never shutting down which would cause the drain - I know Lincoln offers a upgrade to the 4G work but is outrageously priced. Let me know thought if you think that could be it

I recently bought a scope for can wiring diagnosis I just wonder where do you hook up your leads to? Most can networks have + and -, does it matter which one you hook up to?

you're the man.

Just acquired grandfather’s 2016 3.7L MKX, has only 12,000 miles. Put new battery, air filters etc, drove home 750 miles. Week later battery draining parked overnight. Unplugged a AAA device from port under steering column thinking that maybe cause. Now battery holding for days but on last road-trip and since last jumpstart the Nav and infotainment have gone black? Car driving fine just missing all the tech

The cause of this is the "welcome" feature on your Lincoln (when your car seems to wake up once you get close enough to it with your key fob). If your Lincoln is dying overnight it's because you're parking your car close to the house or in the garage, and keeping your keys in a spot close enough to initiate the "welcome" feature, door never opens, allowing it to fade out, and then once off it re initiates the same feature and same cycle over and over until your battery completely dies....you're welcome. And if you actually watched this whole video ... 🤦 You'll never get that time back

Looks a new model to be giving trouble. Isolating the networks has done the business. Very time consuming exercise but seems to be showing results. 3 amps is a bit over the top. Too troublesome for a dealer, especially with the extended timeframe involved. You'll soon be crowned 👑 of the parasitic draw division.

Someone mentioned in a comment how locking your vehicle can prevent some electrical draws, not sure if this is true. I think the commenter was talking specifically about Subaru's.

I'm about 9 mins in and wondering, if ambient temp was cold enough, one couldn't watch the fuse box with an IR camera when the amps spiked up and get an idea which fuse was heating up then see which modules were powered on that fuse. Together with your scoping the different networks might narrow it down to a single, or very few, modules really quickly

My 2017 MKZ when I first got it, had an ACM firmware issue which caused the module to never sleep correctly. It will kill batteries. Pretty known issue across Fusion/Fusion Sport and MKZ. I'm not sure about MKX. All those modules are tough on batteries, especially cold.

What is concerning me more than anything is the fact that these cars are taking multiple hours/days to diagnose. I just don't see this fitting in with the dealership business model. It isn't likely a service writer/dealership is going to commit the time, training, equipment and expertise to properly diagnose these issues. The best part, these are NEW cars.
