That ended up being the problem with the car I was working on. Crazy.

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. I blame Nissan mostly, particularly if what hellhoundTX333 says about it "being a problem for 20 years" is true.

    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.

    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.

  • @Craig1967

      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.

    This reminds me of the lady's car I worked on once. Had a six disc cd changer that wouldn't play discs. All her cd's she had in the car were all scratched because they were not in the plastic cases. I tried some clean cd's I had with no scratches on them and it still wouldn't work. I pulled the cd changer out and found a bunch of loose change inside of it. I think her kids thought they would get a candy bar out of it by putting change in it 🤣🤣. No reprogramming required? Cool. I like plug and play modules.

    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.
    Very often 2 of the modules will include the Terminating Resistor, and finding out which modules have them is a bitch...
    Years ago, I faced similar issues with Arcnet coax computer networks that needed the same Termination Resistors at each end, and if one was missing, the whole network would stop working..
    Amazing that you tracked it down...

    A nickel and a hair pin cost them many dollars in repairs. My grandson stored his dimes in the lighter plug in back door of my wife's 98 Olds. She told me her interior lights JUST quit working all of a sudden. That's the only time I ever got paid for working on my own car. Think I made 40 cents on that job. That's also the only time I've ever kept anything I've found in a customers car. I always use a plastic bag to store coins, pills, lottery tickets,etc. and place it in front passenger side floor. You find some really odd stuff any time you do dash, console or seat repair. and if they have kids, the back seat is a real treasure trove. GOOD JOB IVAN and THANKS.

    This was a very interesting one. I’ve actually had a similar case study a few years back which took me a couple days to solve. In my case the car was intermittent no start and also the engine would cut out and not restart after going over a bump at times. The end result was the lady’s toddler had been posting pennies (cents) into the CD player slot. They had made their way to the main board and were randomly shorting the internals. It was only after removing the unit and placing it down on its side by chance that I heard all the pennies jingling around inside. When I went to show the lady the issue she answered the door holding her child. During explaining the issue to the lady her child pointed at the radio and said “banky” 🤣 I instantly understood what had happened.

    At 7:51 , I think pulling fuses works only when can bus shows 12 volts which would mean module shorted to power .If not at 12 volts than disconnecting the modules is the best approach , some modules require a lot of extra time to get to.

    Reminds me of back in 2000 when I bought this 1989 Celica GT (5 sp manual) for 1200.00. The car had been sitting for about 3 mo. and had a crank no start condition. 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? It seemed to connect just fine, so I thought for the heck of it, why not try and start the car. It started right up. It was unbelievable. The car ran great till I finally sold it just a couple months ago.

    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.

    One of my diagnosis instructors told us about this problem! Dimes were the main culprit, they fall in and short out the circuit board, and the updated modules just have tape over the slot.

Nissan is known for a bad ground wire from the transmission to wheel well causing back feeding that will pop the coil fuse . If this ground is bad and fuse is popped , all coils should be tested/ replaced . Hope I'm wrong .

    "I can't believe it was the last module I had to check"... it always is. At work I'll have a stack of identical measuring instruments, let's say, for the sake of argument, thermocouple amplifiers/readers and I'll be looking for a particular ticket. It's always one of the last two labels I check.
    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.

    If I wasn't a Nissan tech I would have been pulling my hair out tracing this down (much like yourself). Good work though. This is a pretty common issue to see at the dealer - whether its from spare change falling into the unit, or customers that remove it during radio installs having no idea what it's for. After reading the description this was one of the top guesses I had - was watching just hoping you'd pull the dash apart and find it. Nice vid on the issue - you'll save a lot of techs on diag time
