It’s time for the PHAD 2024 Halloween Special!
This 2012 Nissan Titan with over 200k miles went into LIMP HOME MODE and refused to start the next day. Apparently the ECM is offline.
The owner said it spent 6 WEEKS at the Nissan Dealer, and 13 WEEKS at another shop with NO RESOLUTION! In fact, now it’s BUTCHERED!
ECM and IPDM have obviously already been replaced…
As a last resort, he had it towed it to PHAD 8 HOURS from Michigan.
Let’s dig in to this “Possessed Beached Whale Titan” and see if we can find the GHOST…

 Nissan Dealer & Shop STUMPED for 6 MONTHS?! (Possessed Titan No-Start)')){kind=link}
Big difference cranking with a good ECU, it was trying to inject fuel and fire plugs. First ECU definitely bad, and second as well. TRhe only difference between 6 and 8 cylinder ECU is the programming flashed on them, the actual drivers for the extra cylinders will be there, as it is cheaper for Nissan to make the ECU in bulk, and simply flash it on the way to the assembly line for the vehicle, as they have to in any case flash in the VIN, and an extra 10 seconds of flashing the latest firmware is already there, so making it generic is no extra time at all. Just different option bits set in the ECU, telling it which maps to use, and number of cylinders and timing to expect.
You're constantly getting better, and better at being a problem solver! As i am a poor old backyard mechanic, I really enjoy your videos!
Man, that brother in law went above and beyond on his diagnosis. Good for him. Great information given.
I have a new flagship one computer for a 99 jeep that's burnt on a completely different driver than the original.
I run a garage in Lewistown, nice to see someone else able to fix the un fixable.
I wonder what the code is for Titan Truck Missing.
Nissan no run.
It would have been a really fun surprise if it started and actually ran on all 8 cylinders.
However it would have been interesting to see codes after the crank attempt. It could have at least revealed some other possible issues.
The TCM that sometimes was available seems to me to be a bit of an issue, but we'll see later.
I knew the V6 ECM was going to scan because the check engine light came on immediately instead of a long delay.
curious the original issue was a limp mode. always go from the beginning. what causes limp mode? work from there. it seems to be the same scenerio. customer tries then other shop then dealer and then ivan. too many fingers making too many other problems. does make for fun watching though!!!!!
I still don't understand why the TCM is usually down. Is that TCM built into the ECM? I also don't know how the truck knows it's in park and can display a prndl with no TCM.
Firing order is completely different definitely wouldn't run on the V6 ECU
What is Flagship1's business model? How do they make money selling broken ECU's? Surely everyone should be sending them back for a refund and surely their name is just mud now?
Every single automotive repair channel I watch, if it's got a Flagship1 "reconditioned" ECU in the car, then the ECU is faulty
Just because it’s new, doesn’t mean it’s good…
Is there a place to repair the computer
Nice video.
I visited a fairly well known ECM store not far from here. I needed one and was going to pay extra shipping costs , then realized they were 20 miles from me. So I went there.
It was a guy in a semi trailer with boxes of used ECMs, and he was painting them flat black and putting decals on them.
You working the night shift now Ivan?
One guy actually told me point blank that how to repair a car is find the cheapest thing it could be and replace that, if that doesn't fix it then replace the next thing on the list (by cost), replace that and keep going
Main reason people struggle with diagnosis is that critical thinking has gone by the wayside in education. It has been replaced with rote memorization. If you dont know how something works you cannot fix it if the answer isnt in the book. Service manuals will usually get you in the neighborhood but if the answer isnt in the manual knowing how a system works is 100% necessary to pinpoint a problem.
I have tried numerous times to explain issues and what was tried to a service writer. They smile and are polite and then you see the service ticket and all it says is "Customer states car wont start".
I’ve seen and experienced plenty of poor “reman” pcm stories. If manufacturers aren’t going to supply electronics then they should release the design info to see if someone will build new units so good vehicles don’t get crushed.
Just my thoughts.
Flagship! gets mentioned again
It's a sad day, that the customer does better diagnostics than a maun dealer and many repair shops.
Good on the customer for giving it a really good try.
It absolutely amazes me that in this day and age, a factory dealer can't fix their own products, which begs the question, Why even buy a new car when after a certain amount of time it will become unfixable even by the "factory-trained mechanics"?
I think one thing that probably makes a difference is the customer recording what they tried and what the results were. At least then you know what has been touched already.
