The Final FRONTIER...No-Start, No-Comm (Part 2 - Reman ECM?) 

Best Mechanic on RU-vid Period . This guy knows how to troubleshoot I love watching his videos keep them coming !!!!!!!!!!!!!!!!

I put a Flagship One ECU in my Honda Accord about 3 years ago and have not had any problems since I installed it. I've seen some complaints about their products/services but I have none. Lifetime warranty on the ECU as well.

Outstanding! That company did a fantastic job with the computer.

Ivan, I suspect Flagship One is like any other business. The more computers they see the better they get. Diagnostic equipment is also getting better. I also hope auto manufacturers are becoming more sharing with their schematics on these devices. From the comments below it sounds like Flagship One is committed to a positive outcome as an end result. Hearing that truck fire sure sounded sweet! Thanks for Sharing!

Wow good job! I was a mastertech at a nissan for 20 years. I like watching your videos. It reminds me when I was on the field. It takes skills to trouble shoot different brand like you do. In Quebec where I live, corrosion appears sooner then you. I’ve seen a lot of problems with ecm cause by the battery to body ground just next to the battery. There’s a little bracket that can be discard to avoid voltage drop. Also, the immobilizer is located in the BCM. It means that you can simply cycle the key to program then. Can’t wait to see you troubleshoot other nissan!

Just watched What’s up Wednesday with Eric O now I got Ivan. What a great day. Thank you both for all the knowledge you pass alone!!! Man Love from Billy G

Thank you Ivan. I find the most difficult to diagnose car problems are computer based, electric signals and their devices. You really focus on these... so again thanks.

I just took apart my GM van ecm cleaned it out checked solder joints 2003 with 360 k miles still perfect. I sealed up after to prevent moisture water entry.

It would be interesting if you could ask the repair facility for the ECM why your backup/spare computer was buzzing, hissing, or fizzing......;-) It would also be interesting to know what they fixed and how. Did they find a blown component or just reflow some connections? Great video as always Ivan.

This is my truck! Ivan is amazing, if you couldn’t 😂 truck still going strong thus far!

got my fs1 ecu in two weeks. had cold weather no start. pluged it in and started right up' no key reprogram or anything else. hardest part was getting that bottom bolt out. very happy. 2007 pathfinder.

I bought a ford exploder from a dealer non running and sent computer to flagship one and had one mishap with it sent it back and they fixed it no problems. Like you said have to give them credit they are getting better i believe. Always enjoy your videos. Thank you.

I've never personally delt with FS1, but I know a number of people who have. And it's been mostly good stuff from them. Every one of them had no complaints with their customer support.

Great job!! I have same truck 2005. Giving me gremlins and phantom codes. First , o2 sensor, then weirdly the crank sensor. My mech couldn’t figure it out. Thought my ECU was fried. Saw this, ordered new one from Flagship. Got car running , let it idle for 15 minutes or so, then idled jumped to about 2k, 4wd light went on. Shut it down, dials on dashboard ( rpm and speed) started jittering and clicking. Tried to restart, nothing battery felt dead and did read about 8 volts on ammeter of dash . Disconnected battery. Went back to your videos. Can’t figure out. Must be a communication issue. Man I wish you were on Staten Island or can refer me to someone just as good as you here. Keep up these great and super informative videos.

I just started watching your videos man you're good I got a no calm no start 07 Miata waiting on a PCM hopefully it'll start will keep you updated

Hi Ivan, kudos to Flagship One, well done everyone and many thanks. From Nr Liverpool UK.

Ivan, I had my Pcm off my cummins repaired at ELSEEA repair in Victor NY. Not to far from Eric O. Very happy with them

My family has had like 6 of that platform truck and this video makes me miss our old frontier even more. Just a port injected v6, normal 4WD with low range, no front axle disconnect, and an optional 6 speed. Plus IMO the engines sound great.

I love watching you work and walk us through your thought processes, I only wish we had some like you, as skilled here in Australia

The Final Frontier.....These are the activities of Ivan Temnykh......His continuing mission......To seek out strange new issues......To establish new methods of repair and replace......TO BOLDLY DO WHAT NO MAN HAS DONE BEFORE!!!!! All kidding aside, I got the distinct impression you weren't thrilled with Flagship 1. There always seemed to be some issue with something they did; looks like you have them headed in the right direction. Now, if you will excuse me, I am going to enjoy some traditional Russian Borscht. Great video!

Well done. Btw, you have a nice place. I always enjoy watching your vids and your surroundings.

Purchased the Thinktool Pro S from Ivan's Amazon store. Ended up paying $789 after rebates and discounts ! Love the Tool so far.

It seems like you have a 50/50 shot with Flagship 1, but it also seems they keep you 100% satisfaction with them

I'm keeping both of these videos. I have an 06 Frontier 4.0L, 6 Speed Manual, 4X4, with an ARB Air Locker in the rear differential. Mine has 117,000 + miles on the odometer. It is resting in my garage, will be coming out near Christmas to haul gifts to family members on Christmas Day. When we have snow (Southern California, Antelope Valley, Palmdale) the 4WD makes it easier, and sometimes fun to drive. Good fix on this one Ivan.

Good on Flagship1. Another confirmed diagnosis and repair by the Russian Yoda of diagnostics

Hey Ivan. Thank you for sharing this information. Merry Christmas to all!

I can’t pass up one of your videos. I had to chuckle remembering the last diesel truck I had. I sent the fuel injection control module off for a rebuild and it fixed the crappy running engine. And the same truck had a knock in the suspension system that my wife couldn’t hear and said I was obsessing over. It turned out to be a shock bushing.

Hooray for Flagship 1. Glad you brought this to a happy ending.

Great video, diagnosis and out come. I was worried you would have to take part of the pasture to store all those beached whales. I guess you could create some car art like the Cadillac ranch down in Texas along I-40. 😂😂

Wow, flagship made the right call and actually fixed it? Lol. I'm amazed by that lol. I've heard horror stories, haha. Nice fix!! At least everything is working! Great job Ivan!!

Glad to hear Flagship 1 was able to come through for you. Unfortunately that wasn't my experience. How about reading their terms for warranty to the subscribers. The part that got me was if you use the warranty once the life time guarantee is done.

Ivan you are always going above and beyond!!!

What about "Maic Salazar Diagnostics" for your ECM repairs? I recently came across his RU-vid channel and seems to be good at repairing ECMs and all sorts of modules. Plus he usually makes a video of the actual repair too. I think dealing with an individual instead of a corporation will get you better customer service for sure! I can't vouch for him, no idea how good or fast his service actually is, but maybe worth a shot if he's got a good rep. If anything, his videos take you deep inside the ECM and various modules and help you get a component level understanding of how they function. Who knows, it may help you start to get to component level module repair, we all know you like to actually fix the problem and not just replace the bad modules.

Congrats on a successful diagnosis and a very happy customer. It doesn't get better than that. God bless the work.

The final Frontier....sounds like old Star Trek with Scotty and Kirk...Beam me up.

👍👍to You Ivan, and ditto to Flagship for this one. Nice work!

Big happy Ending for ivàn💯👍🏻

I got a FlagShipOne on my 06 Jeep Liberty. 4 years old. No problems.

Great diag and repair Ivan

GREAT Solution in the end with oem original ecm Fixed..

Nice work, technically a No Parts Required Repair? ;)

Nice title (a play on Star Trek's opening theme).👍

I'm not a big fan of Nissan's, but I like that year Frontier. Fingers crossed for the owner.

great videos, i have an older nissan pathfinder doing a similar thing.. im gonna check the immobilizer relay first but I think maybe the ecm or perhaps the key code got reset when draining the battery. I really hope my ECM isnt blown but It wasnt connecting also so

I hope Flagship keeps doing good

WONDERING WHAT THE LOUD POP WAS THAT STARTED IT ALL

This Guy is not a mechanic this Guy inginer his super good is one of the best technicians I haven't ever seen before good for this Guy congratulations to have guy's like this they can help us to pinpoint some ur problems

Flagship 1 took months and 2 computers to resolve the issue with my 1994 Jeep Grand Cherokee Laredo. Not a good customer service experience at all but eventually all is working very well.

Very cool! Say - When they refurb a component, do they describe the nature of the failure, which components were replaced (if any), etc? No doubt some 'fixes' are cold/cracked solder joints if it's like any other modern electronic gizmo. Might wanna talk the customer into having the 2nd ECM sent in for repair! (I like having spare parts on hand. ;) )

Ivan when will the time come when you get a computer repair station going? Npr ecm repairs with a microscope?!

Good & smooth diagnostic. Would you mention the cost range of fixing or refurbish the car compter?!

Nice job Ivan, I think our thoughts on Flagship one are very similar. I hope they're doing as good a job for everyone as they did for you this time. Perhaps your national exposure has picked up their socks a bit. Their service is almost indispensable in today's auto industry. I hope they step up :~>

Nissan 4.0 6 speed manual . . . Dang...... 🏎🏎

I think I would have checked the sleep current of the repaired module. Then I would make sure the cooling fan(s) are cycling correctly and confirm the fan(s) operation with live data with the scan tool. Usually, I find the EVAP monitor will not pass until the tank is below 3/4 full and above 1/4 full, and it will require two drive cycles (trips) of proper set condition operation.

Wish you were closer, my haunted truck has visited 4 garages with a crank/no start issue that is still unresolved.

I'm sure the knowledgeable information, symptoms, and test results, did a great job of providing them with direction!

Way to go! So any info on what went bad in the original ecm? Thanks Ivan

Hmm... I would never have plugged a good ECM without first doing a resistance and voltage check on the 5V wires to see if there was a dead short or spurious 12V backfeeding from somewhere. I literally puckered up when you did that. And then you didn't kill the power immediately when the noise happened.... As mentioned by some other commenters, that whistling was probably an unhappy switching power supply, possibly because of being under heavy load (think the mysteriously low 1.5V on the 5V rail). It is possible you still have an intermittent short on the 5V line, which could reassert itself and blow up the 5V supply again... As mentioned, it would have been good to ohm out the 5V line while you had the ECM connectors off.

Very cool. Thanks Ivan!

GREAT PROGRAMMING! IF U REFURBISHED EXISTING ECU....WHY DID U HAVE TO RE-PROGRAM?????????

IVAN, great fix as always really enjoyed the videos and good for FLAGSHIPONE will be looking for them for used computers and did ur scanner think tool pros give the pin code for IMMOBILIZER or u pay for it to get the CODE thankyou and as always learning from the best cheeeeers.

Tbh I hope that's not the way it is and that they give all of their customers good service. Cheers

Well done ivan :-D The nissan is no longer a garden stealer lol. I hope flagship One keeps improving it's diagnostic ability. They are needed. Being ripped off by the stealerships or the parent company is greed. Don't i moan a lot lol :-D

Great video Ivan. Only question I have is. What's the difference between the thinktool pro vs the pro S? Any input would be greatly appreciated because I am looking into buying one.

Good video. Thanks

I have a 1992 Nissan Sentra Sitting here that has a Vin number of 666 and Believe Me it lived up to that Vin Number.

Awesome video, I'm needing to replace the ECM on my Pathfinder, it looks like the same setup here. Do you have any advice on how to remove the bottom bolt on the ECM? I can NOT get to it.

Great ending, Ivan! I'm still wondering about the parasitic draw - did it go away after ECM repaired? Could be the ECM drawing through faulty 5V reference.

Amazing you can send a dead computer to someone and it come back perfect again I love that

I remember Scotty Kilmer telling a story about a guy he knew back in Houston who 'refurbished' engine computers, the extent of the refurbishing was spray painting them silver, lol

Is there a tool that you could plug modules in to see if they are good? They should invent one as it would surely cut down on the parts cannon.

I always had good luck with flagship one

Flagship one for the win, all in all Nissans are pretty good, I can't remember any vehicle where they screwed the pooch

Anti-climatic but glad it worked. I don't think the owner would of had that level of success with the other shop even if they made the right call.

Is there any possibility that you could have done what flagship1 did? or is it quicker and cheaper to let them do it? great job Ivan

Maybe Flagship one finally getting their act together.

I'll be shopping for either a car or pickup 1972 or OLDER.

My brother had an intermittent no crank no start. I could not figure it out. I found a PDU recall. He took it to the dealer and they replaced the PDU for free. Solved it.

My Pathfinder is making same noise from same spot front shocks lower bushing

What was causing the buzzing in the "parts" ECM that eventually went away? Also, I'm wondering how Flagship actually tests the ECM since there are so many with different configurations. Perhaps you got lucky. Maybe you'll be able to fix them yourself.

Thanks my ecu went in my 2015 nissan frontier 😒

send it in get it back plug it in , start it up and test ride. Wait for snow. I will send it.take care.

Ivan, are there any other computer rebuilders beside FlagShip 1.

Come on ivan..Ivan... I'm team #partonefinal

What type of screwdriver did you use to unscrew the bolt from the ECM from the car

Should be called Flagship 100000000

If they repair the same computer you still have tobreprogram? What about if you buy used one same code

Does your scan tool check the 4wheel drive system. I am sure that my 2013 Nissan Titan makes a chime while you rotate the 4wd switch, but now it’s gone ,but the 4wd system works fine. Will the think tool able to turn the chime back on.

2008 Nissan Titan LE. When I turn the key to the On position, the security light remain on constant, the cooling fan comes on, the lights come on, and the vehicle does not start. I need help getting the vehicle back on the road - can you help?

How much was the ECM repair Ivan? If you could share.

Why dont you send ecms to United Radio in Syracuse? Great group of people

Maybe they watch people tear apart ECMs and replace parts and have started doing that along with testing equipment for many vehicles, there is money to be made if you can go beyond finding computers in junk yard vehicles that work. Getting a bunch of 'dead' computers from repair shops is a lot cheaper than maybe working computers from junk yards, a broken computer you know what the problem is while junk computers may have intermittent problems you don't know.

What 'Popped' in the ECM? Did they say what they fixed?

Hi sir good morning, please i have a problem with my Nissan frontier, security light is on, but the is no check engine light. So please i need your help. And i have a code u1000.and i check the wires, they are ok.

This control unit is normally attached to 2 screws at the top and bottom. And not on a screw like in the video. But how do I get to the bottom screw? It's a shame you can't see that in the video

Does Flagship1 tell you what they found wrong with the computer?

Yea! 😆

does FS1 tell you what they found and fixed?

I don't have to go through all the muss and fuss to "program" my keys: the Friendly Hardware Store copies them very effectively. 🙃🙃

Dude how much did it cost for the reman ecm??
