Customer Spent $4000...and it STILL Doesn't Start! (Acura MDX)
The owner of this 2010 Acura MDX has been waiting for a month for me to make the trip and diagnose his unpredictable 2010 Acura MDX that intermittently refuses to fire up.
The green "Immobilizer" key blinks on the dash when the car is acting up, setting a mysterious "D-2" fault in memory.
This was a tough diagnosis due to the intermittent nature of the problem.
You will NEVER guess what the problem is!

I also owe Keith one, it was 2 bad fuel injectors in my mom's van and a faulty rad cap causing the water loss
The owner of the Acura was my favorite part of this video. A good-natured guy, in spite of spending lots of time and money on this problem. He even participated in the video!
In the early 90s I came across a 1982 Honda Accord for sale. It was covered with dirt from sitting. The owner was driving it, & it cut out on the freeway. Everything shutdown. She took it to Honda, & they replaced all kinds of parts. A few days later it happened again, so she took it to another shop, & they continued to replace everything they could think of. She drove away, & it cut out again. She had it towed home again, & was afraid to drive it. I bought it for 300 hundred bucks. I was grateful for all the new parts! It made it home , without cutting out. I spent a few hours going over everything under the hood. Then, While letting it run, I started grabbing the wires underneath the dash, & It shut down. It was a connector green with corrosion. I'm not sure how the water made its way under the dash, but I paid 50Cents for the connector at the JY. That sure was a nice little car.
What a weird problem! Luckily, Keith (the encyclopedia of weird cases), was able to save you the time it would take to chase goblins down the wiring. Great diagnostic and hats off to Keith.

When you call Ivan as the last resort and he has to call his last resort :)
I have an 04 Maxima with intermittent click-no start issues. I've tried new brushes, new solenoid on my starter, new relay, new grounding cable, i checked voltage drop on positive and negative side i even tried a new starter and a new battery - couldn't get rid of the problem. One day i just grabbed a handful of wires under my dashboard and wiggled them and the problem was fixed. The car has been starting super strong for a few years with zero issues. (The new starter was returned and i'm still using my old original starter) After a few years the same issue is back but not as bad. It's time for some wiggle-wiggle again. I may try kicking some things too 😄
$4k for "Green Crusties" 😮...... This proves that Ivan is always right about never using the parts cannon without a proper diagnostic. Well done 👍

The owner was too fucking stupid to Google? Apparently so…..
I had the same type of no start problem intermittently on a 2006 Accord. First problem I fixed was the ECU that had some damage from water dripping from the AC system. It was actually physically corroded the aluminum box and insides so I cleaned it up, put some spray plastic type stuff meant for circuit boards on the ecu board and sealed the casing better. That corrected the problem for a while but the final fix was to simply replace the ground wiring after which I had no issues with starting and no longer the green immobilizer symbol.
That feeling at 26:30 when you pop the connector out and a hail of green dust follows 👏
holy cow that it was amazing who would have ever thought a dang connection and a kick panel is going to affect your smart key crap
I truly miss Keith's 3 min long video's. Glad to hear he's still got his head in it. Hope his wife and son are loving the new life.
Good old water intrusion and of course Keith and his wealth of stored information..

Kieths a legend what doesn’t this guy know
Wow. What a case study. And Kieth might be the GOAT…..This is what you love to do Ivan. Solve the mysteries others cannot. Wow.
Your a top notch troubleshooter, I'd hire you in a second. I do have one constructive criticism comment. I've watched a lot of your video's and I've heard you say a few times it has to be a module. I was an electronics technician for 40 years and I have seen some weird stuff, bad grounds and crusties acting like resistors that can cause some weird results. So maybe don't be so quick to say it has to be a module even though you are usually right. Please don't take this as negativity, I give you top marks on your skills and I'm still learning too. In fact I learn a lot about cars from you. Keep the videos coming.
Crazy how Honda builds cars with pattern failures that luckily transfer from vehicle to vehicle. I always say they’re not perfect but very well built cars! Great find bro!
That was incredible! That’s wild that Keith pulled that from memory. Now, fix that smoke alarm chirp….😊

After cleaning the contacts mate and un-mate the connector a couple times. Then apply Deoxit D100 in the needle applicator bottle to the male pins re-connect and test for proper operation. If operation okay, you can then seal the wire side of the connector with Grote Ultra-Seal. The Ultra-Seal will keep the water out. Usually the power feed and power return for a specific function will route through a common connector. In this case, if you do not have the ability to replace a pin, you could add a connector and move the circuit power (which has the bad pin) and the return using a Deutsch DTM 2 Pin connector. You can select either a bent style crimp pin or a barrel style pin. Most common are either Tin plated or Nickle plated. Pins with Gold plating are available but very expensive. If this is done it is generally good practice to tie wrap the added connector to the parent connector.
keith defazio top graduate of the staten island school of diagnostics and every weird wired auto the man is a legend
That MDX body style were notorious for water leaks through the roof rails and A pillar and water would always find its way behind the MICU. Good find 👍
Nice to phone a Guru when you need it.....Give him a 9 volt for the chirping smoke alarm Damn....Nice one Ivan.
Brilliant deduction! I had such a grin on my face when you found the pesky problem!!
My favorite fixes are the no parts required ones. That was going to be a biatch to track down though. Amazing Keith ran across that and kicked the panel and found out. Divine intervention. Our cars here in So Cal are only impacted by heat. We have no rain or rust so ideal conditions for cars to survive. You'd be amazed what you see still running out here.
Up until the point you rang Keith, you were so convinced it had to be a module problem and not a wiring/connection issue. That it turned out to be the latter after all must have left your mind reeling a bit, Ivan. Feel for you. Experience can be painful, but you just passed another milestone. ✌Thank you for letting us be a part of that journey. 👍
That was it, you got my 2011 acura mdx up and running after 3 trips to honda, new immobilizer and reprogramming and still intermittent issue exactly like this car. I took your expertise and advise and now it's all good. Thank you so much

That's awesome!! You would think the dealers would know about this apparently common issue lol!
I know you would have got to the cause eventually, but you had already told yourself that it was a module problem and definitely not a wiring problem. Several modules were already tried and sitting on the table. That experience Keith has really pays off, and now this problem will not phase you again! You know... until you check that wire first and it's completely clean.
I'm really impressed With your awesome Diagnostics... You indeed Nailed It!.. Green Cruistes...4k grands for replacement of innocent parts😢
One of the best automotive diagnostic channels on yt imo.
I have a 2002 ACRUA MDX that I bought early 2020.. It has 3 rows of leather seats that fold down, heated seats and heated mirrors, moon roof, COLD dual climate AC that works TOO well.. it's AWD; has 3.5L vtec (j35A3) engine. It's in emaculate shape, zero rust, zero dents, not a single drop of leaking oil anywhere on this thing.. It had 155k miles and I got it for $1700 off of FB marketplace. lol.. over 2 years later and I'm still thrilled about it. It's such an incredible car........ It has an interference engine though, and I'm not sure if it has ever had a timing belt done on it. So that's on the list of things to knock out sometime in the future... I love these things though. Absolutely flawless design, even back in 2002. Everyone is trying to copy this exact crossover shape/ style and function, ect... -- and Acura got it right all the way back then..... I used my Xtool D8 to make extra keys and fobs for it. What a find-- I'm still pinching myself.
This just happened to me... i was all over the place... and came across this video... thanks 🙏🙏
Awesome case study as always. Thank you so much for sharing. Always enjoy them!
That was awesome, you and Keith never fail to impress Ivan !
Love these complicated cases, makes my brain think!!! Great job Ivan and Keith!!
You had a fault to VBAT and the immobilizer output is an open drain transistor with some series resistance to the transistor drain. The +5V is the normal logic that this immobilizer output is pulled up with a resistor at the partner to this module. All automotive outputs must tolerate VBAT so a fault list this one does not destroy an output resulting in a new module. Faults like this are the bane of electronics.....
Wow, Keith to the rescue. That call saved a bunch of time. You would probably have gotten there but man oh man, what a fix! Super cool!
That was a great vid IVAN>you've done a lot of the green crusty's ones before but this was special in that you asked for help,and Kieth DAfacio came through with a needle in the haystack idea and it was right on the money.i really think 90 % of mechs,would just keep firing the parts canon until the barrel melted or the customer ran out of money.what makes it such a good lesson is THAT IT'S AN INTERMITTENT ISSUE.Those are the hardest to repair.I'm sure this guy had no issues paying you for travel time.i know if it was me>>i would send a stretch limo to pick you and your wife up and take you back wherever you wanted to go.haha
Good job. Always love the No Part Required repairs. Keith is brilliant for having remembered that problem. Miss his videos. Thanks!

Hey Ivan, when you asked yourself the question "would I have found that failing footwell connector on my own?" I think you would have, given the right circumstance. But I'd say Keith just earned himself lunch. LOL. But my personal experience tells me, does the vehicle have a sunroof? If answer is yes, it may be worth a look in the footwell areas for signs of water intrusion. This is great content Ivan! A perfect example of what to look for. Thanks for sharing this.

Awesome job. Best diagnosis I've seen. Weird problem, but you handled it well. Great job. You're the best.
You are fantastic with that scope, would not have found it without the scope and your knowledge of using it. People like you and Keith are invaluable.
Hi, Kudos to Keith and to you to have the humility to ask him for help. If you don't ask you don't get. Many thanks for ALL your excellent and VERY informative videos. From Nr Liverpool UK.
That one was wild indeed! You would never find a problem like that without the aid of a scope unless you just accidently stumbled up on it. Great diagnosis and video. Amazing what problems a few green crusties can and will cause.
Love the videos Ivan. No criticism here just an observation. You can buy bulk assortments of OEM male and female connector pins for all makes and just re-pin the bad connector pin(s). It's very easy to do once you get the hang of it which I know you have the skill set. A special crimping tool is needed and an assortment of pin extractors for releasing the pin, all of which is very inexpensive. With a little practice there is no need to order harnesses or disable other systems in the car and the repair is 100 percent at the time of diagnosis.
Love how Keith has had that problem before , Master Tech ! Thanks Ivan !
If there were only 10 world class automotive diagnosticians in the world then you and Kieth would each get 9 Christmas cards. 😃
Great job for sharing. I am sure you would have found the issue after the owner called you back. Great to have friends, we can't know it all. But you do a great job at it. Love the analysis you do and explanation! God Bless you!!
Great Video Ivan! I was leaning towards the wire problem since it had the parts cannon already shot at it!
Holy Cow. Having a mate who's been in the ring before can relate crazy stuff. Connector in the side panel?? Green Kreep shorting 12v to a com wire. What a pal. You knew when to call.
Very good diagnostic ❤ i followed you since one year ago and i get a lot of information every time i watched your video
PSA: It's not a bad idea to use eye protection when spraying contact cleaner... I've gotten chemical burns on my hands a few times from CRC QD, would hate to get a drop in my eye.
In all honesty I believe you would of found the problem. I know Keith helped short cut the find but I do believe you would of found it eventually. Its nice to have someone as knowledgeable as Keith in your corner. You just gotta know when to call him. It's a better learning experience when found on its own but unfortunately time and money doesn't always make it possible.

Yes, Ivan, unbelievable. Nice that you gave Keith the credit on this fix - makes you an honorable man. Oh, I flew into Binghamton, once, in the Winter, and there was snow piled VERY high on each side of the runway. I was working on my Commercial license and my instructor was with me. He was actually delivering something there, and offered me to fly the trip for more experience. Was a memorable trip. ha, ha.

Great diag very interesting and Keith saved alot of time , you would have eventually found it on your own I'm sure.Location of connectors seems to be key kick panels seem to be a common place for water to seep into . Watching lots of diag videos over the last few years connector issues and green crusties always in vulnerable areas either inside or outside the cabin. The customer is ecstatic hopefully can resell the parts cannon ammunition on ebay again and retrieve some $$$$.
