[@jeffjankiewicz5100]

You have an amazing property and view Ivan. Lucky guy.

[@dustcommander100]

I'm with the other commenters who think the hissing sound is a switched mode power supply. Could be how the ECM makes the 5V reference, but it could also be how the ECM makes all the power used internally (I don't know what other voltages it uses). That's just how power is handled these days. Sometimes the noise is an issue, sometimes it's just normal and just wasn't noticeable before. It would be cool to put the scope on the 5V reference and see how much ripple is on it. In the non-automotive world, high ripple voltage is one of the failure modes of this type of power supply - and if the computer runs on 5V, it would be very confusing to the computer if there was a lot of AC ripple there. Very interesting diagnosis, and so cool that you had a spare! Just consider how many ECM's are out there, and how lucky it is that you had a partially compatible one!

Good evening Ivan. During last week. I've been driving about 300 miles total to diag a 2013 explorer would not start after the owner disconnected the battery to his truck. He was doing other repairs and playing it safe. After he got done. He reconnected the battery and no crank and no start.?? On the first run. We discovered a broken encoder ring. Luckily he had bought one. We installed it and cleared codes. No luck. Still dead. ?? Engine fail to start message During my scan. I did some more research. My Dependable launch scanner would not allow me to go into the bcm to see why or how many keys are available. With my tail between my legs. I head home. Now back to research. I find a program call Forscan for Ford vehicles to code keys and code modules. I order it. Tell the owner. I have another car I'm finishing up. As soon as it done. Bring the truck up. 2 days ago I get the truck. I load my laptop to the truck. I'm allowed into the system. I see the bcm is there and online but I see no keys programmed?? I try programming the old keys. Nope. Truck says keys are already programmed?? I sleep on it. Next morning. I buy 2 new keys and get them cut. I successfully program 2 new keys. Still no start. ??? A youtuber says similar thing happened to him..says bought a new module. Just like you taught me about powers and grounds. I recheck things. I go back into the bcm module. All info is still there.?? I Ask myself a question. Maybe the bcm went to safe mode by shutting itself down?? I go back to the bcm and initialize the module. This entire process I'm at 4 hours into the diag. And then the final test. Truck starts. I test the old key and it still works good. I'm very very new to this kornputer stuff. I sure learned alot from you sir. The next day my wife's niece shows up with her Taurus. I also get 2 new keys after the dog ate the remote😄😄. So..this Forscan program cost me next to nothing. I can work on ford vehicles after I buy the extended liscense. I'm super happy and my customer is pleased too. Next on my plate is any 07 silverado. Crank no start. I'm getting spark but Injectors are not firing. Wish me luck. It's another 2 hour trip to and from. I'm donating my time to help and elderly couple. 😄😄 and I'm 67 now..

[@basshunter428]

Oddly enough I just recently purchased a PCM from FS1. I gave them the VIN# (for a 98 Wrangler Sport) and expected a working unit. What I got was something completely different! I made 5 phone calls and sent pics before they would accept a return. I then tried to purchase one from a Jeep dealer. It was discontinued (not a big surprise) but I did get a part number based on my VIN and it was NOT the part number/PCM FS1 sent me! Then when I told them the part they had sent was wrong (as per Jeep) they tried deducting an $85 "restocking fee" from my refund! I will NOT do business with them again.

[@PineHollowAutoDiagnostics]

Ugh customer service is hit or miss..

[@JoseSilveira-newhandleforYT]

Great title and great diagnostic! That hissing on the ECM sounds a lot like an internal switchmode power supply being overstressed by excessive drain (+5V?) - maybe that's what made the original ECM make the "pop" sound customer mentioned. I would be careful when the replacement ECM is installed - could be an intermittent short on +5V. Very curious for Part 2 :-)

[@jessicav2031]

Shouldn't every automotive electronics device be tolerant of a short on the output? Just like every pin should tolerate being shorted to battery? It might fail to function properly until the short is resolved but it shouldn't cause damage. I thought that was the standard.

[@cygnus58]

Good call! SMPS!

@@jessicav2031 Yep, but aged electronics may fail with a bit more stress than the usual.

[@Sandmansa]

@@jessicav2031 Should they? Yes. But do they? Not always. I know that the early (99 to 03) Volvo S80's for example, have no external relays for the O2 sensor circuit. If an O2 sensor had a high resistance load or dead short to ground, it will burn the circuit board inside the ECM.

[@richardcranium5839]

why on earth would you install a switch mode power supply on a strictly dc system??? you would need an inverter to power it. if it had both 5 and-5v rails its possible but there are better ways of doing it.

[@mrjamespenske1881]

Your cliff hangers are something else! Makes people want part 2 even when there isn't one like its fixed but there must be something else wrong you could fix!

[@cyberslacker5150]

Ivan. CHANGE THE THROTTLE BODY TOO. The hissing sound is likely caused by the ECM constantly adjusting the throttle body position. The throttle body will eventually fry the new ECM. I'm sure you know that Nissan's of this era are notorious for the throttle bodies blowing ECMs all the time. If you don't replace the throttle body with a NEW one (not used, not refurbished, sometimes refurbished short out the ECM too) your going to blow the ECM too. It's happened to me lots of times. When I started diagnostics I blew four replacements ECMs on a Murano. Lessons learned. Scope the throttle wires. It could me that, or it could be something else. It's wise to do some checks before replacing the ECM.

[@davidanthony1569]

That weird noise from the ECM sounds a bit like an overloaded switching module.

[@moayado436]

Right on the money bro

[@jessicav2031]

Or maybe a bad capacitor on a switch node? It's weird, I would expect a high pitched beep and not a broadband fuzz. Modern switching chips have intentional frequency jitter for EMC but that sounds excessive?

I'm curious about the 5v system! I'd like to put an amp clamp around the 5v ref wire, or even unplug the ecm and ohm-check the harness to ground. Should be a very high resistance ckt that only supports milli-ohms of current, right? Also, with the bad ecm, you could use your own external power supply to bring the circuit back to 5v and see if the original computer will work again! Either way, and based on the other comments about the ecm's sizzling sound, it sounds like you'll be tracing down a 5v issue in the harness, I'm guessing related to the clutch explosion/changeout. Can't wait!

Impressive work as always Ivan!

[@jcmobilediagnostics8611]

On any car if the 5v ref is shorted it will be a no com except if the vehicle has multiple 5v regulators. The 5v ref is a modules internal power supply. If you pull that down, the module cannot power up to function.

[@PineHollowAutoDiagnostics]

Definitely an essential check before condemning any computer 👍

[@donkaiser6704]

Your substitute ECU was hissing because a switching power supply inside it wasn't working correctly. Probably because its load was either shorted or open; possibly because the switch mode inductor came loose from its mounting....

[@jackpatteeuw9244]

What do you think of this as a diagnostic step AFTER detect Vref out of spec. Assuming there is only one Vref, cut the wire near the computer and measure the voltage there across a load. Yes, you now have a wire repair, but you know whether or not anything in the rest of the Vref wiring pulling it down.

[@dharley189]

That’s how we were taught in the 90’s on Chrysler systems. They had multiple 5v reference wires but tied together internally. Diagnostics have sure changed. We had scopes but never used to check data lines back then.

[@windward2818]

Problem happened after repair work. Check to make sure there are no missing ground connections or a pinched harness in relation to the work done. A popping sound can mean that a module capacitor exploded. Most likely it is a surface mount AL Electrolytic.

I'm putting some money on bad electrolytics inside the old ECM which may even have been worsened by some moisture ingress. That could definitely explain the 'pop' in the passenger compartment as that is where the ECM was located. Main filter cap probably went kapoof. Meaning that ECM may even be fixable if only the capacitors went bad.

[@randy1ization]

that truck is giving hints.,., first a loud pop, then no comm,, now a computer that is hissing, likely a capacitor gassing out due to a short.. sounds like there is an intermittant short somewhere.. I wouldnt put a new computer in until its found. Im wondering if when the clutch job was done, they pinched a wire to the body or frame somewhere or plugged something in the wrong connector.

[@AP9311]

I have seen a dodge durango oil sending unit short and pull the 5 volt reference down to around 1 volt. The tps signal would act like its sending a signal but with a 1.1 to a 1.5 volt range. I believe that was how it acted, it could have been pulled down to 2 volts and read 2 to 2.5 on the signal wire. It acted like the signal voltage from 1 to 5 but in the tenth of a volt scale . unplugged that sending unit and everything was normal

[@bradfaught1695]

I bought a 11 pathfinder same engine, intermittent stall with a crank sensor circuit code. I finally got it to act up yestetserday and gave it reach around and read 2.3v, cranked it no change. So I must of been on the 5v feed. I'm expecting a harness issue since it's only code I have.

I cAnt get it to act up now but I have power, around 2.3 on the signal and ground.

[@mikecalvin1402]

[@byrd203]

Ivan, if a computer makes a hissing sound, that means it is trying to put power on a trace but can not go through a resistor that's out of spec, either to high or too low or missing ground on the data line where it is cross-talking over anther route that's the sound you hear check to see if you hear a resistor going bad or is bad

[@MakersEase]

My armchair quarterbacking... The hiss was whatever was pulling the 5v reference down was pulling too much current - replacement ecu able to overcome the draw?.. (the switch mode supply was whistling..) then maybe burned out what ever was taking too much current? Just thinking out loud.

[@PineHollowAutoDiagnostics]

Also hissed with Key OFF...

[@MakersEase]

@@PineHollowAutoDiagnostics Oh - so never mind :)

[@roxanneabbott8424]

I like the way you think. Now on my Nissan frontier I have a no com. So I'll go with the simple things I need anyway. New battery. Pos ground post. And all relays that run other fuses and of course the 2 ECM relays. 1 passenger side , other in fuse box second over bottom. As I hope the ECM is good after I reboot it. If not it will get the boot. I'll order another one as I see just have to match part number and give the vin. To get the right one. A shame the code doesn't say no com. --- simple fix. 😀 👍

[@Sandmansa]

Interesting case here. So, the other shop made the right call? You would have to admit that it had all the right signs to point that way if all they did was test for powers and grounds. But we can all see that you were very thorough. Still, an unanswered question remains. What caused the original ECM to die in the first place? They don't just pop for no reason. Any possibility of opening up that dead ECM?

As you had with this Nissan either part or the whole system usually goes down, plus a load of codes are set that makes you know its impossible for all of them to be set under normal conditions. As these vehicles age and you plan to keep yours, its wise to get a spare ECU, either used or new while you still can.

Oh Ivan, your video was blurry, hard to follow along. Was that your focus or screen on computer? Still a good video always!

I had one of these trucks, the overheating on mine was caused by a bad radiator cap - they are considered a consumable and only last about 30,000 miles. 🤦‍♂

I wonder can it be revived with external 5v? )

Ivan, my friends mini van Vauxhall 2002 does not want to start over 1 year now, they fix it and its ok for about 1 month and then again it does not want to start, then again they fix it and again 1 month later is dead and this cycle still continues for about 1 year now. Its horrible.

He did say something popped. Think it's a relay?

[@Friend_of_the_One-Eyed_Ladies]

To me, 5:15-7:15 is completely redundant. I know they teach guys that way in tech school, but seriously.... if you test powers and grounds AT THE MODULE and everything's good, then you know for a fact that everything upstream (fuses, relays, etc.) is just fine. I don't see the point of doing it in reverse order like this, especially when the module is right there in your face easy to access. Possible exception could be made for intermittent problems, which this wasn't.

Maybe that hissing noise is actually a fuse about to detonate. Lol

[@greg778123]

Are the Horses in the background. yours ?

[@foxccc7517]

Ivan any videos Xterra issues?

[@nickmalone3143]

Hissing could be a bad capacitor in the ECU
