my wife goes crazy if radio does not work then she gets to hear all the weird other sounds.

Back in the 60's a radio never kept us from driving the car, nor did the radio ever mess with the windshield wipers. Progress is wonderful.

I always learn something. Thumbs up for your tenacity.

You know Ivan...The more I see these new rigs more and more I appreciate my 1942 Dodge Army Truck..and my 1971 chevy half ton Pickup ~Your A Swell Mechanic and we all Honer that-Thanks 👍😎🌍

I have a 2011 Town / Country. When I bought it it had a Sony aftermarket radio with an adapter for the steering buttons. I replaced it with a better unit and while installing it, I turned the key on without the steering buttons adapter powered and I got the exact same problem you had. I turned the key off, added power to the steering buttons adapter and that fixed it. yes, the interior CAN bus being open was what made the wipers come on. There is also a video from Eric O with this same problem. In his case, the wires under the rear carpet were broken. Same bus goes all the way back in a Van.

Man, NO BUS Stellantis videos are some of my favorites. It always looks like someone fed fentanyl to the fuse box 🤣

Great diagnostic of a bus problem without the Pico - that's unusual. I was already expecting to see the bus going berserk on the scope 🙂 I guess "multiple annoying little problems" are also a Jeep thing 🙂

I like how you give us the conclusions and follow up bonuses at each case study video... Rarely No Cliff Hangers for this diagnostic technician!

Crazy how a radio can cause that... These vehicles these days are quite interconnected!

Great job Ivan.

Just started watching this video. We had a Jeep act the same way. It was a bad TIPM. Previous owner had replaced the TIPM with a refurbished unit and problem recurred shortly after we bought it. We got the previous owner to request a warranty replacement and had it installed. Still had problems but some symptoms were different. Bought a "new" TIPM from a different company, and the problems went away. Sold the Jeep.

Good lesson. Thanks Ivan!

My brother asked me to look at his ex's little foreign SUV thing years ago (can't remember what she drove now, been too long), but he was asking me to figure out why the outside marker and interior lights suddenly didn't work, as well as the door dinger and some other random interior stuff. He had pulled the radio out cause it crapped out, and they hadn't put an aftermarket one in yet like they wanted to. I plugged the factory one back in, and even dead it made everything else work again. He had to leave it in till he got a new radio

I've never experienced it but, on the Panther platform cars we have something called "Wacky Wiper Syndrome." This causes the windshield wipers to start working for no reason even when they are switched off. Seems the cavity where the wiper motor is mounted fills with water because the drains are clogged. I was thinking you had something similar here. Nope. It was the radio instead. Great video!

Ivan did it again, I didn’t expect anything less. 👍🏼

Nice and simple diag! Just pull the radio fuse out, lol. The radio carries the network of its not functioning right, it'll interfere the network on the tipm! Nice job Ivan! Surprisingly you didn't do a scope job to find the module fault! Awesome video!

Nice job Ivan 👍👍👍👍👍👏👏👏👏👏

Again Ivan, you cracked the case wide open. Always enjoy these videos, but I wonder how this guy is going to enjoy his new radio with that seat belt dinger constantly chirping.

Ivan you are a saint! I get a kick out of the myriad of electronic glitches that you can successfully diagnose. Yes,I watch all of you and Eric’s videos. Way back when I was a kid I had a 1943 Ford Jeep, had lights one wiper driver only. All that was necessary was gas,oil,grease, and brake fluid. It traversed the roughest terrain that West Texas had to offer. Was the best dang Jeep either side of the Pecos!

another genius diagnostic.

No bus! That’s right, it’s a jeep 😂

IVAN, thanks for showing ur PPROACH /THOUGHT PROCESS always learning from the best. cheeeeeeers

Even though engine teardowns and mechanical issues are fascinating, I love the air of mystery that network/electrical issues bring 🙂

Awesome video!

Good diagnosis regardless of using the oscilloscope or not.

My guess the micro switch down in the seat clasp needs a clean & adjustment. Short but goody one Ivan.

That’s a crazy case study

Well if it was me, I would say address all issues, at least I know that they will be fixed for good. But I do not see myself buying such a vehicle. Ivan is the Man.

I don't know if your the best diagnostician on KZfaq. But your one of the best and my favorite.

Excellent diagnosis. You used the most important computer too. The one God gave you between your ears. I know you mentioned it but as an almost Fifty year professional technician still driving a 99 Accord the electronic failure rate and lack of parts and technicians understanding is more than a little concerning. Also. You don’t charge enough for figuring this stuff out when no one else can. You deserve to be well paid for fixing these multi thousand dollar vehicles that would otherwise be yard decorations 😳

The shop owners own vehicle 😆. I like farming out DIRTY stuff, but love the challenge of evicting dashboard elves.

love your videos! really good work! =) / a swedish mechanic

automotive active obsolescence! Good luck keeping up!

It sounds like the stereo has a cold solder joint somewhere on the printed circuit board. Thanks Ivan.

Chrysler has had other issues as well with that style of radio. We had a van at work where the speakers would only work when really cold out and would only work for about five minutes or so. When it was warmer out, they wouldn't work at all. Maybe they should go back to putting 8-track players in vehicles?

Check near the driver's door retaining strap. There is a grounding stud there. Had that problem except for the stereo worked

On my xtool D8, I can go into the BCM and click the special functions in there and it has options to turn off the seat belt dinger; and also usually turn off the auto door locks when to shift into drive, and also the automatic roll down windows, dome light shut off delay, etc. You can turn all that stuff on or off if you want. I'm assuming it will be in every decent scantool. (at least I had all those options in my 2002 Acura MDX- but the car is pretty loaded and fancy with heated leather seats, heated mirrors, moon roof, auto dimming rear view mirror, dual climate control, etc.-- so maybe not every car will have all those options).

WOW he is good.

I just replaced the cluster in a jeep for a parasitic draw. I noticed that with the cluster out I could start the vehicle but could not shift it out of park. Also the windshield wipers ran anytime the key was on. Replaced the cluster with a used one and all was back to normal.

Ita a problem with the IHS net work. The wipers stay on and the head light stay on also. It's a safety precaution Chrysler builds Into their systems so you can get to your nearest destination so the network gets restored lol seen this a few times on the ram 5500 6.7's. Great vid Ivan man!

That crazy wiper issue is a Chrysler thing, part of the design so you can see what you are about to slam into when the electric steering fails, I reckon

First radio upgrade that I ever dealt with that was connected to canbus to power on was an 08 grand Cherokee. New radio I just left that two wire connector Disconnected.

Wow, a self diagnosing Chrysler product! 😂

Well for the time being the Jeep is back!

I've just had the cluster repaired on my ford cmax. made loads of issues with the car. Locking unlocking doors. Not starting. Going into limp mode with mechanical failure warning. Modern cars are just too much trouble! Repair was only £100 though and all works perfectly now.

You area very smart man.

Had strange problems with my PT Cruiser and Jeep liberty. Both problems caused by water somehow got into a connector under dash. Cleaned connectors all's well. Never figured out where the water came from.

I feel your pain, dealing with Peugeot, Citroen comms 2000 in the past, which were always a pain in the backside. I give French/Italian wiring three years before problems. Now Fiat/Chyrsler/Jeep vehicles are with us, life has just got a bit more interesting. Serviced a Fiat 500L 2019 and had to hook up the SGW lead to reset the service light, just another way to make life difficult for the independent. I suppose we could all go out and buy connex for 12000 lol.

Wow, almost identical symptoms to a 2011 Wrangler I had a few weeks ago, except mine had a functional radio and a bad multi-function switch that was messing with the LIN bus. The SCCM and SAS modules being offline certainly has my curiosity piqued, though!

Ivan, To have an early 60'2 Chevy, Dodge, Ford again. All this technology seems worthless. It keeps this channel going. Love your stuff.....Pete

Thanks Ivan for another great video.

on some Chrysler's models the front wipers and headlights turn on when there is a Can issues and it is a default state for safety

I've often heard people use the term clusterfuk, didn't know what it meant until now, thanks.

Aint got no gas in it!

My 2016 Jeep patriot JUST today. Wipers won't go off even though turned to off. Fog light come on and off randomly during driving. So. I Google searched Patriot electrical problems. Here's your sign. Lol Thanks

The estate I manage has a few jeeps and one a dem turns the wipers on one time when the piece of junk is started. Non serviceable ball joints are a jeep thing. New control arms.

Hey Ivan: Maybe you could make a video showing how you keep track of all your recordings--- how you organize your video clips and keep track of all your follow ups's, etc. It seems like you always have several videos in play at once-- and waiting a few weeks here and there for the follow up, etc. However you keep all those files organized and how you do your editing (using premiere I assume)-- ??? I think it would just be cool to peek behind the curtain and see how you keep track of everything and get a sense of your standard editing routine and how long it takes, etc.. I'd sure be interested in seeing that. cheers.

Guy must not have used the radio enough and it got tired of being ignored. Still nice diag Ivan! Cheers. Reminded me of my dad's oldsmobile, he tore out the seat to remove the dinger. Guess he really didn't like the seat belt. GM stood for "Gawd, Mom" I guess.

It's a Jeep/ Fiat / Chrysler thing.. When they work they're ok but when they fail or the plasticky bits "piss" oil all over, no fun!

maybe a wet amplifier. jeep doesn't put things in very good locations, and everything seems to get wet on them. when my seat belt latches act up, i spray some contact cleaner in the slot and latch/unlatch it a bunch of times.

I have a JK 2011 and does exact thing - I unhooked the battery waited 15 minutes and problem "solved" definitely a gremlim

Thank you Ivan for the loony tunes network! The network CRC error checking should stop broken messages. Maybe the Think tool could either merge with Pico or add more network checking capability. The think tool knows who is who so theoretically it should be able to monitor all good and bad modules messages to verify where the garbage is coming from. It's only going to get worse with more complexity.

We have a 2010 Dodge Nitro that has a failed ABS which causes the traction control light to come on. Apparently it's a very common failure (at least there are a lot of videos talking about it across many Mopar vehicles). I checked all the speed sensers in the scantool and they all work fine. The clock spring is bad too. I'm just not even going to fix it. lol.. The heater core is a 9hr job, and I just bought her a $15 heated seat cover and she's happy. So we're just going to keep running it as is. :). We should have sold it a year ago before it started all falling apart. Da^n the luck

I haven't watched the full video. First thought based on our 2015 Cherokee Latitude, steering column spiral harness turned out to be a spendy but correct part replacement. Wipers started at end of normal drive to church when parking. Climate control went blank. Was a dry day so we pulled the wiper fuse for the drive home later. Dealer thought it was resolved with some software updates, but turned out not to be the case. Many lose of communication errors and most related to controls on the steering wheel or column. Dealer called and stated it was a little bit of a stretch and expensive shot to fix, but best their best techs could conclude as the likely culprit. Thankfully it turned out to be the correct diagnosis for our Jeep.

Just fixed my issue same problem before seeing video would of saved lots of time, been dealing for couple months now. I caused it with Andriod aftermarket radio KEY1 KEY2 for steering wheel controls made mine go crazy. Once disconnected everything fine no 🎄.

Feb 28th. 12th LIKE 👍 of the month. 🤠🇺🇸

have a 2011 Grand Cherokee that would intermittently go into limp mode , diagnostics targeted the BCM , the transfer case shift module , the airbag control module ,the traction control module , turned out to be the transmission selector switch on the console , they have had 4 revisions of this part and not told anybody , do not trust the diagnostic functions on Jeeps , nor the electrical reference guide , for example , poking around under the dash i managed to blow a fuse controlling the cluster lights , checked the 2 fuses the company said controlled this ,no good , random contact on Jeep forum suggested a third fuse(not listed) which was blown ,renewed fuse , hey presto i had lights again !

I guess he shot himself with the parts cannon. You could probably make three or four more videos diagnosing all the faults. 😂

This surprises me that pulling power to the radio apparently relieved the symptoms because there were two options to take. One, remove power to the unit and two, remove the connector buss on the radio. Removing power would not eliminate proximity shorts and opens to the buss with wiring, on-board hardware shorts and opens and loading issues, capacitance and inductance. Removing power would find any on-board electronic component / driver issues.

I enjoy watching your videos more than regular TV. You could have your own TV show. I wish you would make a video on how to use the picoscope and software and breakout box and what subscriptions are the best for diagrams.

Like many Chrysler products, the wipers come on as a default (safety feature?) when certain electronic problems occur.

Great job! I predict that you will have all the work you have time for, until you retire or decide to pursue something else.... Why would the radio affect the wipers? Because "computer". That's what they do!

I've never had confidence in Jeep and here they can't sell them....Without seatbelt the bonger is out.. 😂😂😂

Had a '97 Caravan that the wipers would turn on randomly. I put a toggle switch in it.

Another American special

Wizard just fixed a similar problem on an Alfa Milano. A bad ground was causing it. In the case of this Jeep it may have been the radio since taking it out of the system by pulling the fuse stopped it. When he replaced the radio the new one got a new ground. I'd almost bet there was nothing wrong with the old radio. If there was an internal ground short, it should have blown the fuse. 30A seems to big for a radio.

Hubnut would approve of the surprise wiper action, I'm sure...

Had an 06 Grand Cherokee that, at 8 years of age, started having electrical problems. When I started the car everything on the dash would blink intermittently, car wouldn’t go into gear among other issues. Shut it off, restart and be fine. Traded it right after that. Last Chrysler product I’ll ever own.

I’ve had luck with ignition switch and clockspring

Bests thing is, he got MUSIC!!!

Hey Ivan, I’m also a diagnostic technician and Ive diagnose the same problem on a Dodge Caravan. I think its a Dodge/Jeep/Chrysler thing 😂 These radios are garbage 😂

When the factory radio died in my cousin's jeep, it somehow caused a parasitic draw by keeping the bus and all modules active. That shouldn't be possible as far as I'm aware. Instead of using a switched 12 volt source, the radio listens for messages on the bus and wakes up that way. It should not be broadcasting data that would keep other modules awake, but maybe the data it was transmitting was so garbled that the other modules didn't know what to do? Idk. Ripping the stock radio out fixed the issue and a Scosche dash kit and JVC head unit was a great upgrade.

I carry a bus pass whenever I ride in a Jeep.

Had this started to happen to me with my 16 jk before I traded it in but not as bad as this one. TPIM gone bad.

I'm just constantly wondering where these cars are going to be when they start pushing 20-30yrs old. Or are they all just going to be so far gone with electrical/cpu issues they're not around.

Maybe it’s supposed to say take the bus lol

When the bus system goes down, the wipers will turn on as a safety feature.

I'm surprised the radio was not causing a draw also, to pull the bus down you would think it had to short or ground it, those radios do get hot, it's surrounded by the vent tubes, solid diag as always. Have you had to work on any autoauth Chryslers yet? Would think it's a pain if you cannot get good internet signal while out on the road.

As a 30+ year 12 volt installer, I would bet dollars to doughnuts if you were pull that factory radio one will find some coins or bobby pins inside placed there by a bored toddler. I have seen this first hand, once with a dash fire. A 30 amp circuit is easily able to start an electrical fire. Add a plastic radio case and now you have a party.

I'm assuming you checked the oil first thing. Seeing that "oil pressure low' -- I'd be paranoid running it without KNOWING there's oil on that dipstick. I would assume you would check it as soon as the hood is open, just as a regular habit. So I have no doubts. ;). I know it's not related to the problem at hand -- But I just don't assume; it's bit me too many times: and it never ceases to amaze me how customers will run their cars all the way out of oil, not even know it, and keep on driving it.

Wipers and headlights are defaulted on Chryslers when there is no com. I believe heat and defrost are as well. That's their limp home strategy.

Wow now the Dinging .would drive Me half bonkers, At least the Switch for the belt should work 🤢

One of these days you're going to whip out the scope and pressure transducer to verify a low tire pressure TPMS alert. Lol. April fools special?

No transmission problems that's weird 🤣🤣

cars will drive you crazy

Evidently the odometer must have gone bezerk at some point also. 😄👍👍

👍

Pull the radio see what comes back.

Ivan "The Exorcist" Temnykh casts demon out of possessed Jeep.

I thought for sure TIPM 🤓
