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!

You surely don't owe me a thing. Glad to share the knowledge and happy it led you right to the problem! Great video brother , see you soon!
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!
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.
$4k for "Green Crusties" 😮...... This proves that Ivan is always right about never using the parts cannon without a proper diagnostic. Well done 👍
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.
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.
When you call Ivan as the last resort and he has to call his last resort :)
keith defazio top graduate of the staten island school of diagnostics and every weird wired auto the man is a legend
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.
Keith has diagnosed thousands of cars. How in the heck did he remember hitting the left kick panel in a Honda? Incredible. Good friend to have.
That feeling at
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.
That was incredible! That’s wild that Keith pulled that from memory. Now, fix that smoke alarm chirp….😊
Good old water intrusion and of course Keith and his wealth of stored information..
Keith is a man with impeccable memory and experience! Good person to have in your corner. Good find!
OMG, the Keith guy is clutch, I mean talk about random facts and remembering odd cases, that's nuts!!!
Kieths a legend what doesn’t this guy know
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.
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.
