    Ok, 6 days ago we unplugged smart alternator cable and our 2019 Armada is running like a “big dog”. It runs so much better getting the gas it needs to preform. I was to the point of great hesitation running short errands and taking on responsibility of loading up friends to run around playing. Well no longer, it’s like having a new car. Thank you !!!!

    Thank You! I was working on getting the alternator replaced thinking it was going out. I'm on my second battery and noticed the rev limiting problem and figured out it was related to a low battery charge. I even got a battery with a higher CCA I had resorted to charging my battery with a trickle charger about once a month. I was told that the problem was because I only had short trips and the truck was not able to fully warm up most of the time. Causing the Battire to slowly get lower and lower from driving. This should be something that Nissan Fix's outside of the warranty or at the very least puts out a PSA.

    Thank you for this video. I have a 2018 Armada, which I bought two years ago obviously used. Previously to me buying this vehicle it had two new batteries and since me buying this vehicle, I have put two new batteries in the vehicle. We just removed this plug last night and my car started right up this morning. I will keep you posted! I was getting tired of my car, not starting and having to jump it. And never know when going somewhere if my car would start back up.

      I had the same issue with my wife’s 2018 Amanda. She uses it mostly driving 4 miles ro and from work every day and the battery was requiring to be charged or jump every 3-4weeks. We would charge it and it would run fine for a bit but slowly would become slow to start. Took it to the dealership several times and they constantly said nothing was wrong. We replaced the battery twice and after investigating a bit found this and similar posts and videos saying the smart alternator was the issue. Unplugged it and it’s like a new vehicle. Better throttle response and no start issues after a few months. We still plug it up for long drives or trips just in case but it’s made it so much better.

    Randomly not starting for my 2019 Armada has been a big problem. Nissan does need to be accountable.
    I bought the SUV with 58k miles. According to Car Fax the previous owner had 2 batteries replaced at dealership while under warranty. Now 2019 Armada has approx 80k miles so I’m currently using 3rd battery. It’s been frustrating to nightly trickle charge and carry a jump box around never knowing when it’s not going to start. It’s made me crazy to have a car that I love, yet it’s not reliable.
    Thankfully on RUclips I am finding answers- solutions. When husband gets home we are unplugging smart cable. I will keep you posted and will be a happy camper if it solves it. Thank you !!!

The manager wants me to (maybe VVCS, but can't recall) return so they can do a diagnostic for $183 and he mentioned bypassing something. I am sure it is this smartplug.

    2017 Armada
    Same issue for a couple of years. Even found someone mentioning issues with the A/C not acting properly when idling as a symptom of this “smart alternator.” Had that issue in our Armada as well as the battery drained and caused no starts at inconsistent times. Happy to find your video.
    I told my mechanic about it (because they ran an electrical diagnostic test on it and were stumped). It helped them. They looked into it and said on their certified mechanic forum (not sure exactly the name of it) mechanics are saying that Nissans has it down as something you can go into the dealership to get an update for that remedies the issue with the smart alternator. He also said it isn’t listed as a recall. Soooo, I called the local dealer. North Ft Worth TX area. Lady at the service desk said no recalls. Yes ma’am, I know. She wanted me to come in for a diagnostic test and see if a “bulletin” pops up for that specific issue. I asked surely there is a way you can look up to see if there is a bulletin on a generation of vehicles on a specific part. She said her techs said no, and they needed me to come in for
    the $185 test and see if maybe a bulletin pops up. Pfffft 🙄
    No thanks. Maybe if I confirm from other vehicle owners that are having this issue. I tried poking around the internet for a minute but didn’t find anything about a bulletin. If I knew there was for sure a bulletin I probably would go in and have them do it.
    *makes me angry that these companies don’t recall things that will make bad PR and cost them. Who knows how many millions of dollars Nissan owners have lost trying to fix this.
    Similar with my 2019 Chevy truck (first year of that body style)…got some recalls but had to figure out that they didn’t have the correct transmission fluid from the factory and the transmission needed to be “reprogrammed,” until the symptoms got bad enough to take in to the shop.
    Seems worthy of a recall 🤦‍♂️
    Nope they just make the vehicle owner get beat down with issues and save the bad PR from a recall…just my opinion.
    Sorry for being long winded.
    Hopefully I contributed something useful to the conversation

    Excellent video, and I can't wait to get home and see if my truck has that smart plug. I have a 2017 Titan Platinum Reserve. The battery that was in it when I bought it (used 3 years ago...had 58k on it then, and I now have 86k) lasted until back in February this year. The only "modification" I added was train horns, but we wired the pump directly to the battery and put a toggle switch in the dash inside the truck...so we didn't tap into the fuse block at all, so as to eliminate a potential parasitic draw. I had a couple different days that the truck had to be jump-started. I had power, but not enough to crank the starter. Finally after the 2nd jump start, I went ahead and replaced the battery figuring 3 years was about right. I put in a new battery back in February and then last night when I went to move the truck again, it had to be jump started. I took it in to an Auto Zone and someone came out to put their "tester" on it and she said the battery tested "low" but good, the alternator tested good, but I was told it said "bad starter"...which I didn't buy at all. If the starter was bad, the truck wouldn't have started, AND a bad starter isn't going to cause your battery to go dead. This truck often sits in my driveway and only gets used for short trips sometimes...so your video makes sense. I'll try a volt-meter before, and after unplugging that plug and see what the results are. I will re-post after that. I'm really hoping this is my issue!! Thank you!

    I wish I would’ve known this 5 years ago. I’ve always wondered why my battery voltage would drop so low when I run my ac in the city. It would go down to around 11 sometimes and the air would blow less. I just unplugged that dumb thing and it’s right at 14.4 and isn’t moving. I’m still in the original battery with 67,000 miles but recently I’ve been having weird starting issues where the truck shakes pretty violently trying to start. Doesn’t happen all the time so it’s been hard to get a diagnosis on it. ECU was a concern from other videos but I’m going to swap the battery this weekend and see what happens. Thanks for the video!

  • @mahalsmer
    @mahalsmer 10 месяцев назад +1

    I have a 2017 titan XD, and it keeps going into limp mode. The transmission goes into some sort of a lockout mode, similar to being in tow mode. I have heard that if the alternator has a bad diode in it, it will create AC current in the system, and that will affect the speed sensor of the transmission, causing it to go into lockout mode and I’m getting ready to test the alternator or disconnect the alternator and see if that eliminates that problem even temporarily. I thought it would be easy but I can see that the alternator is down below the engine and not too accessible. I’ll let you know what I find out and I appreciate everything that you’re doing, all the information you putting out. Thanks.!

      I purchased a new 2021 Pro4x and only had it about a month when the truck went into limp mode. After the dealer keeping it for about a week, come to find out it had a bad throttle body sensor. They replaced it and it’s been running great ever since. I now have 48k on the vehicle.
      I did however put in a XS power D4800 AGM battery about 6 months later because I am running a aftermarket subwoofer and amplifier and I was just at the dealership for an oil change and they said the cold cranking amperage was low on it.
      After reading reviews on AGM batteries, vehicles that don’t come with AGM batteries don’t have the charging capabilities they need to keep them fully charged. So if you run an AGM battery in your vehicle, be prepared to give them a trickle charge every now and then. And this was told to me by one of the technicians at XM Power.

    2019 Nissan Titan. I had issues with the engine starting up but only seeming to be running on half the cylinders almost. Super rough idle, try to turn the truck off with the starter button and it wouldn’t react, would have to put the truck in gear and choke it out. Would restart fine most of the time. I took it to the dealership on 2 separate occasions, they had it a total of 3 weeks and couldn’t figure anything out. I disconnected this plug and have had no more issues. I think the voltage was dropping so low at start up that it would affect the canbus system.

  • @aeroengines1
    @aeroengines1 Год назад +1

    Great insight and thank you! So, my 2019 Titan SV has been having an intermittent slow-to-crank problem. I sometimes observe large voltage (driver display) fluctuations when driving and when I do see this activity almost always the next time I start the engine its a problem. Sometimes starting is absolutely normal but 1 out of 4 or 5 starts are sluggish and twice it failed to crank altogether resulting in needing a jump start (battery tested normal after each). The intermittent nature of it interests me since I tend to think this (mostly) rules out the battery itself and places the problem on a "smart" charging system and its components.
    I took the truck to Nissan yesterday who gleefully charged me the full $140 diagnostic fee to tell me the battery was outputting 490 Amps versus its CCA rating of 760 Amps (something autozone or similar could do for free) and blamed it on the battery. This particular battery (AGM) is only 12 months old and if I replace it, as per Nissan's advice, it would be the vehicle's third battery in 35,000 miles.
    My question is this, if the battery voltage is dropping every so often due to charge deactivation, as appears to be the case with mine, why doesn't the smart charging system detect that condition and wouldn't a depleting battery force the charging system on all of the time? Might this indicate a fault within the systems ability to detect or act upon a low voltage.
    Thanks again for putting this out!

It’s starting to drag upon starting, again, and the local dealership told me the battery terminal was loose. They wanted to charge me $80 to tighten it! Of course, when I got home and tried to tighten it, that wasn’t the case. I couldn’t locate a loose bolt anywhere. None of my other trucks had this problem. Maybe because they were SV models and didn’t have as much stuff on them?

I thought maybe the dealership rapid charged the battery from dead before I drove it off the lot. It's always showing between 71-75% charge when first hooking up the trickle. Also have been looking at trying to install an Odyssey group 27, or group 31 "if it will fit". Would have been a $500 mistake if that smart plug was connected as I'm sure a group 31 is going to need 14-14.5 almost constantly.

    I have a 2008 Armada with a lot of miles, some years it got driven a lot, some years not so much, but regardless how much I drive it, I get 2 years out of a battery, lead acid or AGM. I had a cheap $59 walmart battery last 2 years and a $159 AGM last 2 years. Lead acid batteries require a saturation charge around 14.4 volts, also they need a periodic equalization charge around 14.6. Periodic overcharging will desulfate the weak cells. Constant undercharging will cause the weakest cell to sulfate and eventually fail. How much fuel does it have to save to offset the cost and inconvenience of having to buy a battery every 2 years?

  • @TurbineDynamics
    @TurbineDynamics 4 месяца назад +1

    Not disputing your findings, but my concern is the video only proves there is a charging system regulator, what the video doesn't address is whether or not there is serial canbus data present. Most certainly, everything visually seen through the voltmeter makes sense in a conventional sense, what isn't discussed is the constant higher voltages effect on all the control modules running constantly at a voltage they may not have been designed to handle without a duty cycle. The new models use electric pumps in the transmission, which may now be providing a higher than designed pressure, among other systems. The battery can certainly handle the higher voltage without cooking, but the other systems longevity is now in question.

    • @4KMotoring
      @4KMotoring  4 месяца назад +2

      Definitely something to consider, but my opinion would be that the alternator stays charging at high output if you're on the interstate all day long, only disengaging at idle or low load scenario around town to save MPGs or whatever their reason is. If it can handle constant voltage on the interstate for undetermined amount of time, I doubt constant engagement will be a problem.
      Time will tell, I'm hoping to find out more about exactly how the system works to find any potential problems within.

    • @TurbineDynamics
      @TurbineDynamics 4 месяца назад +1

      Oddly, mine fluctuates at highway speeds, same as in town driving, on/off so I'm thinking different years have been modified, if the module is addressable and is also programmable, Nissan may have made corrections, without taking a a few years apart we won't know.

Now, 18 months later at 53,000 miles, truck starting to have those sluggish starts. Also, the crash detection/parking sensor system randomly disabled the other day while driving down the road on a clear day. Possibly a voltage drop?

    The big issue with the VARIABLE VOLTAGE CONTROL is the current sensor is located near the battery along the negative battery cable. If you add electrical accessories to your vehicle, be sure to ground them to a suitable body ground such as the frame or engine block area. Attaching accessories directly to the battery terminal bypasses the current sensor and the sensor is unaware of the additional drainage and doesn’t compensate for this.

      No warranty issues here, just plug it back in before taking it to the dealership.

    Interesting. I've had my 2018 P4X since April of 18, between 0-40k miles I had 2 or maybe 3 times where it would start funny. Start & immediately bog low rpm, electronics going wild. Once I'd turn it off, give it 10s or so, and start again, it was fine. Around 45k miles, I could tell that the battery was getting weak, no real funny business, but it just sounded strained at times. I've had shit luck with OEM batteries in the past from multiple mfgrs. I chalked it up to being an OEM Nissan battery, and went and got a new AGM Platinum something or other from Autozone/Advanced. Just about to hit 50k on it. No issues at all since the battery change, though a much shorter period to notice such a thing. I'm just now hearing about this plug. I may disconnect mine as I dont really understand the point anyway. With a 3" lift and E rated 35s, and a 5.6 V8 pulling a 6000lb vehicle, I can't say fuel economy is great (though not any worse than any other like vehicle regardless of maker) Dumb alternators have been working great for decades....Guess I'll try this and see what dumb can do for me! Hey sometimes dumb works out! Cheers.
