@@dancarney106 Hey Dan. I think you're mostly right. But cars need to be idiot proof, otherwise idiots will find a way to hurt or kill themselves, or damage the car. Nissan should have known that people would find that spot a convenient place for coins to rest. Also, if that hole is an access point for an optional connector or test point that is not always used, then Nissan should have installed a clip on cover of some sort, or even just a piece of gaffer tape - anything really.

[@trelipscomb8137]

Nissan are some of the most misunderstood vehicles on the market today. But you found the problem the correct way. Process of eliminating. Also the explanation of why the car restarted after it died is because the immobilizer had already released the ECM and BCM authorization signal. Since you didn't cycle the key the immobilizer system didn't have to reinitialize. So as long as you don't cycle the key it will start all day.

[@thephantom1492]

@@throttlebottle5906 LOL - yeah, that would be nice. I do miss those days. With my 52 truck, you can see what it does and where it goes. Of course, you'd have wiring looms the thickness of your wrist, if you want to implement the same functionality that modern cars have. CAN is ok; it works well under most circumstances: It is pretty fast, deterministic, somewhat fault tolerant, decent noise immunity, no bus collisions, etc. The protocols (those JXXXX numbers you see your scanner search for) that they bolt on top of CAN are actually pretty sophisticated. But, when the physical interface gets hosed up by a hungry mouse or one module indicates it wants to hog the bus because it was bobbypinned, you're done. It would be better if they had two buses for redundancy. If a module can't get on bus 1, it tries bus 2. If everyone is on bus 2, bus 1 is toast and throw an indicator up. At least the car would still run. It would definitely make that system more reliable. Regardess, Ivan did a great job showing what kind of weird problems you can have.

Exelente Diagnóstico My Friend

[@Fix_It_Again_Tony]

Nice work on the diagnosis. It's more expensive to segment the network into a power train and body control network, for instance, but then you don't have some faulty ancillary module on the CAN network bringing down the entire car. I know other automakers do this. That hole in the module is for a programming/debug connector. You can see when you peer inside that the connector was depopulated from the PCB, they just chose not to make a plug for the hole in the housing or change the mold for the plastic cover to block off access in the production modules. Its common to design a board with footprints for connectors like this and when the design moves to production you just don't populate the connector. In this case the hole in the module was an oversight and that should have been covered to keep conductive material out of the module. Even a sticker would have worked. Definitely a lesson for product designers.

The can Bus is a 2-conductor bus, terminated at each end with a Terminating resistor, and if one is missing, it will cause "reflecting signals" on the Can Bus and it won't work properly.

Nice Find Ivan. From the voltages I believe that HVAC module as asserting itself to a dominant state on the bus, but not talking. CAN− to supply 0 V and (simultaneously) switching CAN+ to the +5 V bus voltage making a current path through the resistors that terminate the bus. This was preventing any of the other modules from talking, they were stuck in a recessive state, because they saw it was asserted.

I didn't know much about cars back then, but I tried almost everything to get it running and was about to throw in the towel when one day I was just looking around the engine and noticed some electrical tape on a wire connector. It wasn't easy to see hiding under some other wires and stuff, but I carefully unwrapped the tape and noticed the connector was kind of loose so I first pulled it apart to look at the condition of it, then put it back together and got a nice click and wondered why the tape?

Which, after a few iterations is actually a good thing as, from that point onwards, I could find the other ones blindfolded if I had to. 🤣 Edit: the module doesn't need the display to function, but, apparently, there's no code to handle the display not responding. So the module "hangs", the microcontroller's watchdog times out and reboots the module. That's why every keypress you made was, seemingly, immediately annulled. The module and the display are not really interdependant, but there's a bug in the module's code which makes it seems like they are.

Wow! Just couple coins and Bobby pin??? That brought the can bus down! Dang! I hate interrelated modules in order to work! I guess it's Nissan thing lol!! Glad you were able to find and fix it! Great job! Awesome video! 👌

[@andrewturchan6065]

You guys have better scanners than we at Honda ......

[@Rein_Ciarfella]

Ivan, you left me hangin’, dude! I wanted to see you put those two fuses back in their slots! 😉👍🔧🧰

[@imp736]

That seat position switch should work, doesn`t work, oh well, what ever, I about fell off my chair. Priceless.

[@jeffjankiewicz5100]

Well that was a wild ride Ivan!

[@drivewasher]

Go on Ivan, take the old unit to bits! Lets see if we can see what went wrong. You know you want to

[@bigdaddymak1439]

Bonus footage with PHAD is like getting bonus fries at Five Guys!! Great stuff Ivan

[@ronw9901]

All i can say is ,wow, never give up

[@Santiago-je5ki]

WOW! a diagnostics like that i'm thinking runs at what $600 + ? Amazing work!

[@vwwrenchie314]

Now that,s what you call a real MONEY light..amazing discovery.😎👍

[@ganeshnarayan5505]

O That's nice put you change in one of the modules. Great video Ivan.

[@1paultv22]

I took an adult-ed electronics repair class years ago and the teacher stressed one thing when working on electronics...90% of the time when an electronic device or a circuit fails, it's usually going to be the first thing plugged in or the last thing coming out, because that's usually where the electrical spikes occur.

[@Cheepchipsable]

Joe's Auto Electric had this problem, but I can't recall the vehicle or what it symptoms were in his case. The replacement unit had two small slots instead of one long one. Designers can't foresee everything that users will do.

[@Cheepchipsable]

IIRC it was a common problem on that car too. People would shove coins in the trim for tolls. There was a "fix" from the manufacturer to put a piece of tape to make the one long slot 2 smaller ones with a bit of tape, as that slot was for cooling.

[@100SteveB]

Who would have thought that saving your loose change would turn out to be such an expensive mistake! And glad to see you put some tape over that coin slot! 😁 But this study just goes to show the pit falls of modern cars where everything runs off the one CAN bus. Yeah sure it might save the manufacturer a bit of wiring, but is it really worth it when just one module going down can kill the whole car? And once that bus is down your scan tools have no way of telling you where the fault is. It is sad to see that cars are made so cheaply these days. I think I will keep my old 1997 Ford Mondeo a bit longer!

[@PineHollowAutoDiagnostics]

I'm keeping my '96 Mercury Mystique too! It's such a solid ride, and handles like a dream :)

[@EL_TORCIDO]

@@PineHollowAutoDiagnosticsI have this same issue but the car I’m working on someone removed this module and it’s a crank no start do u think putting this module back in would fix it

[@chejohnny3706]

great find! yrs ago was a bmw tech, bmw would 'shop' its shops. they'd send out 'customers' to c if we'd mis diagnosis their cars. very common was pennies and dimes in the cig lighter sockets and seatbelt buckle holes. May be grounds for a class action against nissan for that hole. I c there's 1 against bmw for putting the srs module under the cup holder on its x7

[@brucebratschi4300]

Awesome work and I could use your patience. You have a lot and it affects the final result. ❤️

[@JDX123]

Outstanding video of diagnostic procedure!

[@manuelvpr]

This was an excellent job, but I find it crazy that such a small slot allowed that hair pin to fall and short that computer causing the car not to start. Just unbelievable.

[@DJ-tn7vj]

Yo Ivan. When I saw the ac controls not working.i thought to myself that this is going to o be a long bonus videos

[@josephwash109]

If that module houses the A/C amplifier, I'd figure that it has a temperature sensor inside. That hole may also serve to allow the inside air into the module so the sensor can monitor the cabin temperature.

[@notsureigaf]

Nice! Wouldn't be surprised if that unit had a few more coins or pins rattling around inside once you got it out of there.

[@MrTonmit]

There is a TSB on that same problem. Been out for years.
