Nissan Left Customer STRANDED!! (Titan Crank No-Start) 

When you hear your engine start after a malfunction - "oh my baby" I can relate to that. Great job Ivan, as always

Thanks for helping us learn. I am 83 and do just about all repairs on my car and other family members. I enjoy working on cars. Never too old to learn. Life is like that. THANKS for all you do.

95% of techs would have insisted in replacing that expensive module. This is fantastic work!

Chrysler has the same issue with their TIPM, and it's the same fix. Find the wires, cut em out of the TIPM, wire in an external relay. I also think Eric of south main auto has pulled the TIPM apart and soldered a new relay onto the actual board and fixed it, but that requires a lot more work than just wiring in an external relay.

I like it, i like it, i like it🤣 I guess he liked it🤣

That was a great work around and saved the customer a lot of money. Another happy ending.

I love this kind of thing for older vehicles that you’re just trying to make last longer with as little expense as you can.

I love it when you can fix a vehicle without having to replace a part. Genius!

Great job Ivan. When PHAD shows up for a diagnosis it's always what's best for the customer and the least expensive way when possible.👍👍

I love the "no parts required" mantra. I've always been this way myself as well, but you take it to the next level with these work-a-rounds. I'll be adopting these hacks for sure. lol

A genuine diagnosis, by an expert technician, and a cost effective fix, result? A very happy customer! This is the way things should be!!! Thanks for sharing 🥰

You saved this guy Ivan, the dealer would of greased him up real good.😂

That was an absolutely awesome explanation on that. I have someone that was gonna buy a whole other board just to have it running. Your wording and guidance just saved me and them a huge headache. I commend you, sir.

Love it. Especially leaving information for the next person. I’ve done stuff like this for years. I have a starter switch hidden under the dashboard of my 79 Datsun truck. I didn’t think of theft prevention I’m just cheap.

Absolutely brilliant analysis Ivan. Bravo work!

Nice job Ivan!! Almost no parts required! Great fix! Thus saving the client money!! Im sure he'll go back to you on other issues or more fixes!! You got another client on your book! Love it!! Great video! Many thumbs-up!!

It's good you RELAYed that information to us.

Wow! Excellent Ivan! You save that owner a lot of money! Good to see a truck with 180K on the odo and still running good!

Bonus points for bonus footage. That's great labeling Ivan, I wish everyone did that. Very important to show the good example.

Thanks! Same to my nissan Titan 2007 6 months seating and everything I do changed but still not run you are so great after I watch your video I did finally is running

Honestly you have been the best mechanic that thrived on diagnostics, I get that man thank you so much❤

Great repair Ivan ,customer is one happy man .👍

Thank you so much!!! My son's 03 armada is having the same problem. We swapped the camshaft sensor and realized the fuel pump wasn't kicking on. Then after much searching and frustration we found out the relay was built in. We ordered another module but I am gonna rig up a relay just in case. Thank mucho!!!

Ivan is a master mechanic and can fix everything. Amazing he can fix any car problems.

Most excellent work Ivan. Fixing it the way it should have left the factory. FYI, I love relays too, like for example, headlight switches that melt after a time, relay removes the current from the switch that caused the failure.

Thanks for this video. It has saved me alot of time on a truck I'm working on with the exact same problem.

Many thanks for labeling the new circuit, had an old Chevy years ago that someone bypassed the fuse box and shoved the replacements out of sight, naturally the left the fuses in the box....

Hey Ivan. Your videos have gotten very good. Thanks for sharing.

Great fix Ivan. I have found those ISO relays on Amazon with the fuse built into the relay. Makes for a tighter setup. Your patience with these engineering disasters is very enviable my friend. I have some cars in Kentucky if you run short of video material ‼️

I like the waterproof relays for outdoor applications, but this will do fine where it is located. Great work as always.

That was very cool Ivan. Great idea and solution. Bill was pumped!!!

Crazy that a relay isn’t removable...... Nice add on and yes maybe only the external is best maybe

Ivan, you are a master at your craft bro. And you use your gifts for the betterment of others.

We need a lot more people like you who understand all this electronic stuff....

Good on brother,I love watching and learning cheers.

Wow, what a fix. Think I'm gonna have to watch this one again. Thanks for Sharing!

Amazing stuff Ivan! love it

Unbelievable diag and fix. Well done Ivan!

Nice work around. Great job ! Just did similar repair with a plow control interface module for an inoperative plow head light. $300 for a new module or a little study of the wiring resulted in a simple jumper install to correct. Yes I'm a cheap guy, was my personal truck.

Great job Ivan. I love it.

one of your best videos .

Hello Ivan Although it takes a lot more equipment and electrical skills now it is still nice to see that at least some back yard Mechanical repairs are possible. Keep up the good work.

Great troubleshooting and fix Ivan 👍

The IPDM is one of a number of fail points on the Titan Armada platforms. Typically it burns out resulting in a no start no run due to the ECM circuit being burnt. Then you have to replace it or keep swapping the relay over and over until it blows the IPDM fully. Thankfully Nissan actually updated the IPDM and this one doesn’t burn out.

Great fix and great bonus footage :)

Any relay controlling an inductive load will fail much sooner than the same relay controlling a resistive load. The inductive kick back when the motor is turned off is hard on the contacts. Some relays (for DC loads) may have a snubber diode across the contacts to shunt the back EMF when the motor is turned off but most don't. Add to this that most manufactures won't glue a heavy parts like a relay to the PCB so you have a problem with the solder joints cracking from vibration. Then to hide the relay in a 'module' just adds insult to injury. And what a silly place to put the under hood fusebox Nissan!

Brilliant...sure wish I lived closer to you!

Excellent work

very nice find. i had a town and country ( i believe) that has a defected internal fuel pump relay and i remembered the jeep grandcherokee fuel pump relay recall where you do exactly what you did! wired it up and never seen it since!

I love these real world GSD (get "stuff" done) fixes! Sometimes you gotta do what you gotta do.

Wow !! No idea what n how you did diagnosis. The(old school) fix is miraculous !! 👍👍👍👍

Great diagnostic and work around.

Nice work , well done

Great to see the customers reaction "oh my baby" Good job buddy

Great Job saving the customer money.

As always back to basics why if failed can't say it enough !! Thank s Ivan

Educational video. No dumb music. Good stuff!

I love it when the evil engineering of the dastardly designers is circumvented by a thinking technician with a simple solution! Either they don't care about the customer or are intentionally ripping him off.

Aftermarket garbage such as car alarms/engine immobilisers can cause a headache when diagnosing a vehicle which conks out on a person because they're obviously not shown in the vehicles wiring diagram. I had to fix that problem up for my great uncles stepdaughter about 3 months ago & so far there's been no bad news !

N I C E ! Your experience is showing!

Nice work! I was concerned about the parallel connection to the new relay which would have doubled the normal current to the ECM control circuit. But of course, you had already thought of that! Great video!

Nice work Ivan. 👍

Wooohoo got up early and a PHAD video. Going to be a good day

excellent solution, thank you for this video

Dude you are the man! I bought and 08 titan that if you let sit for and hour it cranks and cranks then finally starts. I was getting a code for po850 which is a neutral safety switch circuit low. I thought that was the problem this whole time but I’m pretty sure what you described in this video makes way more sense. The only thing my po850 code causes is it for it to start in reverse and drive and my back up lights don’t work. But this has definitely shed a light on what it probably is causing the crank no start it varies with tempature

Awesome fix! We need more Ivans in the world! I've got an 05 Titan. At least this one has good paint. Mine is baked off the top and the hood. The paints don't hold up well here in the hot south. No rust though so I guess it's a trade off.

I wish we had Ivan in our area. Great work Ivan.

Great fix Ivan!

Great job as always....

Great diagnostic and better solution! These integrated power modules are a pita and manufacturers are stepping into even more integration, which is bad news for customers. Luckily, there is Ivan to the rescue :-)

Another great video. Best wishes to all.

Great way to start my day.

Ivan, you know how to think outside the Box! Very good attention to detail with the label.

I really like how you do a *_clean, thorough_* job--no hurry and run. Maybe think about going to electrical Engineering School. I bet you could build all kinds of run-around fixes. Ivan, you make people very happy--if there is a heaven...you will be there one day because of the way you have kindly treated your fellow man

After working for a major automobile company for almost 30 years, what happens is that the engineer(s) who designed the IPDM is just that, an engineer. Often, these engineers have no automotive experience on the technical/repair side and although they test relays for durability, they cannot duplicate real world driving conditions. So, they run a relay through thousands of tests and if they don't fail, then they say it will never need to be replaced and incorporate it into the fuse box. They aren't concerned with serviceability because in their mind, the part will never fail or the failure rate is very low. I worked with an engineer once that didn't know where the power steering pump that he designed actually fit on the car. I was shocked. I did learn though that often there are very good reasons for how they design things so while it may look stupid to us in the repair field, it makes sense in the manufacturing and safety side of things.

A nice repair of Titan ic proportions! 😁👍🇨🇦

Move closer to me, we need someone like you here. Hard to find good honest mechanics anymore

you're the man way to go !

Best part of the video. Document your work. I did low-voltage for years and years. I hated those service calls when you would open up the cabinet or anything and see a bunch of wires not knowing anything it would take a hour at least to figure out what was what too many cooks in the kitchen when they have subcontractors doing all the work. Great video. Seriously it’s the best I’ve ever seen no joke. What diagnostic equipment are you using? What is the refresh rate?

very good bypass solution..wish we had gotten that 2005 v8 titan engine here in Australia but we did not :(

It’s not a Nissan, it is a Renault. The fuse panel in the back for some of the fuses has to be unlatched and raised to get to some of the fuses. Yikes.

Absolute way to go!!!!👍

Good job man 😎😁💪💪

Yes, 2005-2007 had fuel pump lemons and relay problems strait from the factory. Nissan changed design and manufacturing. But, once relay (IPM) goes……well….your fix is the best answer. Nice Job! Ok👍

I’ve been there and done the exact same fix on an ‘06 Lucerne which also has some of the relays integrated into the fuse box

Great almost NPR repair cost and time effective and a very happy customer . I am always abit worried by the back EMF of some of these general types of relay coils being much higher than than the original factory relay coils , usually those general kind of block relays have a free-wheeling diode installed across the coil to limit back EMF voltage spikes being produced by deenergising relay coil . I always check those general relays have a internal diode installed across the coil then make sure the polarity of the coil supply has the diode reverse biased when energised so it works correctly.

This is a really interesting channel.

Terrific job.

The diode across the coil is there to suppress a back voltage spike caused by removing power from the coil. Depending on the mechanical sensitivity of the relay that might cause a bounce and a momentary contact closure but the main purpose is to prevent the spike from causing noise on the constant supply line. If you reverse the polarity of the supply to the coil, you might cook the diode and blow the fuse but the relay would be fine.

Nice video Ivan. Keep up the good work 👏 Which Thinktool do you recommend Master, Master2 or Master X?

I have a 2014 Ram 3500 6.7L diesel with only 10.4 volts from PCM to MAF. I checked it at PCM (10.4 V) and its supposed to be battery voltage. Have you ever seen anything like this? great videos. keep them coming. thanks for great video information.

Good job

Иван е човека. Ivan is the Man. Thanks

Visited State College, PA a few years ago on business with the local International Truck dealer there. Beautiful region of PA, though the community appeared somewhat depressed economically.

Great work Ivan. I'd have done the same.

Great job , it will be interesting to see when workarounds are attempted on electric vehicles , lol

You are a wizard!!

Ivan, awesome video! By far one of the best I’ve seen! I have a 2005 Titan and I’ve had issues with my relays and fuel pump. I’ve changed them both but I still have had issues. I want to add this as a preventative fix, but want to clarify what you did: Pin 30 connects to battery Pin 85 to gray wire Pin 86 to blue/white wire Pin 87 to black/yellow wire or to fuel pump Now you cut the gray and black/ yellow wire and direct connected them. Did you cut the blue/white wire too and direct connect to it? It was the only part of the video that was difficult to affirm.

12:00 Now that's one happy customer👍!

I am having an issue with a 2009 pathfinder 5.6 4x4. Okay a loose ground bolt on right side of engine caused a smaller 16 gauge wire on left side of engine to carry all the current when trying to start the vehicle causing it to melt on driver's side inner fender. This wire runs under air box all the way into the main harness runs down the left side of engine behind the intake manifold back to the ipcm & ecm. So I opened the harness pulled the melted wires apart the ones that were showing bare wires and no broken strands I used liquid electrical tape to cover wires and the very bad ground that was melted completely I cut out and soldered a new wire same gauge back to the original grounding point. Checked each wire for proper continuity all the way back to the ecm ( battery disconnect and pulled out of vehicle ) all tested fine. No breaks or other wires touching together anywhere else. Put it all back together and found cop #1,2 & 5 were not sparking. Moved cop around and the coils were working on other cylinders but those 3 1,2,& 5 still had no spark with good known cop. Pulled harness again and found more comprised wires that were melted together deeper into harness fixed them put it all back together and now #1& 5 no spark #2 is working again. I put new cop on the vehicle so ruled out bad coils just to be safe. Checked for codes still getting random misfire no other codes. I guess time to get out the oscilloscope grab my laptop and add this vehicle to my alldata diy to figure this out. I feel like it's the ecm but want to check wave pattern and signal quality to make sure it's the ecm. I hate throwing parts when it's not the part that failed
