I'm not here for this video specifically, but I'm sure glad I watched it.
I stopped by to comment on your most recent video to let you know I just purchased your MYODE book in printed form from Amazon -
I look forward to reading it and putting it to great use.
I've always liked this channel. So much useful information here packed into short videos. The man behind the channel has a descent speaking voice. I can hear him and understand him clearly. Mandy, you sound much better than your robot buddy. Stick with this please.
Awesome repair thank you for sharing your knowledge
Awesome repair thank you for sharing your knowledge Big thumbs up
Thank you very much for this valuable information.. could you make a video explaining all of the ECU components?
That's awesome. I love that you are getting into the ECU for a relatively simple repair instead of treating it like a scary mystery box. I'd be tempted to use your discrete part substitute method using higher power FET's as an upgrade to keep it from blowing again
A Sayler I did it just to prove the repair without waiting for the part.
Even more so, how often would a tech just swap the whole ECU?
99% ?? 😁
Dylan that's why i think this is a great video!
Very cool video sir. We're still having this issue 4 years later ha
Keep looking. The IAC control is easy to find and fix.
@@ADPTraining I messed up two solder pads, now let's see if my ugly "hack" works... jumper wires from two pins, one tapping into a trace and the other to another pad down the line to resistor or something whatever it is :D I'll let you know how it goes.
thank you friend for sharing

Thank you Great understand video channel
The same condition exist on Nissan and Infinity vehicles with respect to the EGR control solenoid.So I believe that a video relating to that solenoid driver in the ECM would be most welcome.
I forgot to mention that the same condition seems to exist with the VVT oil control valve.The ECM looks like it is losing control of everything.
Please put more videos like ecu soldering
Super explaination bro
I learned ALOT here.
Thanks for posting.
Thanks sir Nice idea video channel I like more video to learn more
👍
Cool! Although some people do like to know how mosfets work 😉
More videos like this. Great.
Also, we much prefer your real voice to the computer :)
+Benjamin Rich thanks, Benjamin. I'll keep doing videos so long as folks keep watching.
I'm still watching :-)
... and lurking thru the comments too
ADPTraining hello would this work on a 2008 Infiniti QX56?
Why didn't you provide a year range for the vehicles affected? It can't be for every Infiniti model year.
Loved the video and explanation but could you tell me what behavior/ issue the vehicle had. Leading to this fix I have a Nissan lafesta and I feel this is the issue
Irratic idle
Do you think this scenario is related to a faulty ECU. My shifter had stuck in Park for not sending grounding signal to the shifter solenoid. The mechanic made a jumper now the shifter is good, but the transmission shift at a higher RPM. From 2nd to 3rd and so on, you have to reach the RPM to 3200 or 3300 and then the trany upgrade the gear. Do you think the ECU is what causing the trany shifts funky? Thanks.
Grounding the Sol is a bad idea. Your overreaching the trans to force a shift, another bad idea. You need to fix your problem. Yes, the antitheft could be the issue or the ECM or any number of other causes.
Take the signals out with the cable and conect to 4 wey 12v mosfet amplifier its good like that ?
Cool
Hey I'm trying to repair a honda p28 board...my first and can not find were to buy board schematic...do you have any recomendations
That's impossible, anyone that can repair ECMs guards those secrets. I like teaching so I don't mind shearing. Try combing the web for more info.
Thanks for taking the time to teach us. .. do the ecm needs reprogrammed?
Is this should work on 2001 nissan maxima?
Or can i get it from an other ecm and swap just the part? Thank you
colas solorzano just swap part
ADPTraining because i replace the iac. But the idle is up and down. Only in parking .. but when is in drive is normal rpm.. i just can swap the part from another ecm. Right . Thank you.
@@colassolorzano6353 that's what mine is doing. Did you change the chip, and did it look burned or no? There is also a fuse for it as well left side engine bay. I'm going to change my chip hopefully it does the trick but it isn't burned I already checked.
@@WCGwkfdid it help?
Hi sir need help with try to replace the new replacement nissan xtrail euc but car diddnt come with ecu now I need to try to use other modules to the the data and match it to this replacement one is it possible to do it?
You can try a universal programable ECM
I'm really curious to know how you had success replacing power FETs able to manage 3 amps with little ones able to manage 15 times less current.
No, these were 1Amp FETs. And it was a temporary deal for a customer. www.autodiagnosticsandpublishing.com/pulse_width_pwm_controller_driver.html
Maybe this is a long shot. . But any chance that u have the electric diagram. For a crankshaft sensor on a 2011 chevy sulverado 4.3.. thank you.
+colas solorzano no, not really. All repair shops backward engineer them.
Not a bad idea if your having trouble getting the right part.
Hi friend, would like to get training about ecu repair.how can I ??
I have a '95 Maxima. The ECU doesn't seem ground the ECCS relay. I bypassed the relay, now the check engine light comes on when I turn the key ON but not start. Does that necessarily mean the ECU is fried?
Don't bypass, find the issue. ECU may not be bad
@@ADPTraining OK. Someone mentioned the security system and to lock/unlock the car three times. I did that. Now the ECU grounds its relay, and the engine light comes on but still no start. rpm needle does not move as I crank, the crank and cam sensors seem good. Please share any thought as I'll keep diagnosing. Thanks a mil.
Do you know where NATS is located in the ecu? Like if it’s a desolder-able chip?
Unfortunately no, it’s no longer a chip but coded into the ecu software. Only way to disable would be uprev
**besides having access to dealership software. Cheapest and easiest imo
marvellous
Thank you...
Sir..is there any way to contact you...i have nissan sunny...my cars ecu suddenly stopped working...is there anyway to repair it??
Sure, but not remote control. I don't see how.
Hello. How do you know the mosfet chip is the source of problem. Can you explain to me. Happy to hear from you sir.
That chip is the one that controls the iac. 99% of the iac issues are caused by a short which fries the chip. You should also remove the 15a fuse and use a 7.5a fuse to keep this from frying the ecm in the future.
@@venomx4093 hello, can you tell me what is the 15amp fuse, on an infiniti qx4 2001, thank you
very goood work
Thanks
Very usefull!
Freeporn.
how about for 2008 altimas? with 4 cylinders mine idle abou1700 and it wont learn .
Same deal
hi do you have this but for jeep xj 2001?
I have this for ECM repair... www.autodiagnosticsandpublishing.com/ECM_TCM_ABS_PCM_Repair_Signal_Simulator.html
Please what could have gone wrong as am trying to replace accident seatbelt that was stuck but I do not disconnect the battery connectors and the plug was loose from the clip which bring out a loose wire then car dashboard displaying KEY SYSTEM FAULT and would not start. It’s a Nissan. Thanks
Ok, you triggered an antitheft system issue. All these things are tied together. You need to plug in a scanner and go from there.
ADPTraining Thanks buy all the call out that have diagnose the car could not see it reading as they could not enter the car ECU, I have other a reader and will be very happy to no what to do. Thanks
ADPTraining Thank you so much as I can truly see that an icon was flashing in red that show it was and car with key in it, I tried to scan the car and it was connected to the ELM but could not connect to ECM and later said connection problem
Hey Mandy, Awesome video. How did you get the circuit board to come out so clean? I've tried more than a dozen of these same modules and the circuit boards were burnt and deteriorated under the chip. Appreciate your reply
Hamed, how are you. My best customer. Well, I needed to rig this ECM temporarily, so I did what you saw. Customer needed the car. 3 weeks later he passed by, and I replaced with original part. I just picked out that the PCB wasn't lost. I can always rebuild PCB with conductive ink and solder paste. Time consuming though. Thanks so much for watching my videos. Nice to hear from you again, Mandy.
What are the symptoms a car has if I need to do this I have a 1999 pathfinder
Idle problems, stalling.
@@ADPTraining Would these symptoms trigger a misfire code and no other code? I've been struggling to find my problem as it's the only code thrown.
Had this problem six years ago here in Oz with a Nissan Maxima about a 1995 model. This car suffered coolant ingress into the IAC through an oring in the throttle body that stopped the driver in the ecu working. Just another example of rubber seals not working with coolant.
After you fixed that MOSFET, Is it worked?
Yes, but I did this because I didn't have the part. Part was cheap too.
@@ADPTraining still running ?
wow
Good

How about 08 Pathfinder ecm not start when cold 🥶?
Crank sensor
@@ADPTraining I change the crank sensor and both cam sensors and still doin the same I think is the ecm ecu I was wondering if you work on 2008 generation
24v Sany excvator ECM monitor repair solution please help me
What do you need?
autodiagnosticsandpublishing.com
After repaired ecu , white smoke coming
.what is the reason?
You did something wrong or IAC is shorter.
@@ADPTraining no..now its ok..that was mixed up overpumped fuel .Not sure what happened
Can you make a Video on 12v systems automotive Voltage drop ?
My chip does not look burned but I'm going to change it anyway. Assuming I'm not tracking down a bad harness, I'm having communication issues it seems. Have power but still doesn't work with a new iac and good fuse. Ses light does not flash on relearn and with dealer level scan tool relearn process does not work either. Sits on "communicating" status endlessly. Now just waiting on slow ass usps first class
You're doing good diagnostics logic. Yes there's a big possibility that this cheap chip is faulty. Of course relearn stays hanging. That's because it's trying and trying but the IAC is not responding. Keep me posted. autodiagnosticsandpublishing.com
@@ADPTraining I've just verified a short to ground on ecm on one of the 4 signal wires by back probing for voltages and verifying with a test light. Almost certain it's the chip. I'll have to probe around on the ecm board but since nothing is burned I think that's all. Hopefully that's it! Made a video of it just posting now
The STA509A's rating is , ID= 3A , and 2N7000 only 0.5A max. STA509A RDS-On is 0.2ohm , and 2N7000=1.2 ohm , Power dissipation for 509A is around 4 watts per mosfet, the 2N7000 not even touching 1W. You can't replace the STA509A with low rated 2N7000 , it will not going to work , 2N7000 will burnt within minutes. Please download spec sheet from original manufacturer and read it before modify any Mosfet.
You're splitting the current. Furthermore, you're dealing with a stepper motor, so pulses. And you may substitute test and post here so everyone can see, for free, like I did... Thanks.
Soo confused... i throw out my icu... change it with manual carburator...simple and easy to fix out 😂
Good, them nothing to worry about.
may I ask for a design picture, in theory, I want to learn? there is an email address or phone number ... please help me, I want to learn.
