In this video I show the steps and procedures I use to properly diagnose a bad IPDM And a bad engine relay. IPDM Stands for intelligent power distribution module. And Nissan uses them and all of their vehicles to control all the electric functions of the vehicle including the ECM. The ECM or engine relay or sometimes referred to as ignition relay is located in the IPDM. A bad engine really can give you a no start condition. As well as low power condition, also a stalling condition where the engine turns off unexpectedly. A bad eye PDM can give you issues with your wipers, headlights, AC compressor, condenser fan, and various other electronica components in the vehicle. When you purchase a intelligent power distribution module from Nissan it will come with a brand new AC relay and all the fuses already installed for you. I hope this helps some of you out. if you have any questions or comments feel free to leave something In the comment section and make sure to check the links in the description for the parts and tools are used during this video. Thank you for watching

Amazing video very informative and succinct. My Pathfinder is back up and running. ECM relay was the problem for crank but no start

@homesold Год назад

How is the “ECM Relay” labeled in the fuse box for Pathfinder? Having trouble identifying, while working on this crank and no start condition. *Fuel pump is hit & miss when key is cycled.

@kevinlennox1327 Год назад

@@homesold At 5 mins of the video it clearly tells you the start relay is on the bottom row and the third over from the right as you are looking at the board. You can swap it with another relay to see if it solves the start problem, however the start relay is specific so you cannot leave the swapped relay in place as it will cause other issues (It did on mine anyway). The Genuine Nissan replacement part is called a Control Unit-IP Part # 284B7-CW29E. I live in Canada and my local parts shop (Lordco) could not cross reference nor order it for me so I bought it online at a US parts supplier. I bought 2 of them for some silly reason so If you happen to live in Canada I will sell it to you for what it cost me plus mailing costs

@chrisstaten3732 2 года назад

very good video. I am trying to figure out what is wrong with my 2010 armada. I bought it used 2 years ago, and clearly it has been tampered with. (ie previous owner cut and spliced xm radio wires back together, a set of nonfactory rca wires ran to the rear passenger quarter panel) anyway its throwing the park neutral safety circuit code p0850 it cranks runs and drives aside from it rarely starts on the first several cranks. recently I have changed out plugs coils injectors new cats. still no help. the first year I had it I replaced the fuel pump, the throttle body & tbps assembly, and park neutral switch in the transfer case. however changing the coils plugs and injectors did make it start behaving differently it still struggles with starting. before it would take several tries to start & on rare occasions would start on the first try. now it starts stalls out and fails to start several times before finally starting. if I have recently cleared the codes it will idle and drive like normal if the codes are not cleared it will idle higher than it should (around 1k rpm to 12oo) and it throws p0850 , p2101, & p0172 codes any idea what could be causing this issue?

@bgd73 3 года назад

you make it look easy. I towed my neighbors 2006 nissan titan home out of a gravel pit. 5.6 liters. He went through all these repairs..truck quit again the other day. he is in over 1500 bucks at this point. it has been a 2 years path of torture. I feel bad.. he said he has given up and selling it for 500. Truck looks very good. I welded his westin step for him for free. I felt that bad. I can't even joke about my 400k mile gmc that needs nothing ever. Guy is broken over this. I love diving into trouble shooting.. but this nissan, it is hell on earth. I even wondered if it had a nuclear element. No rhyme or reason, erratic hertz like discharges. New everything.. alternator IPDM, relays, battery connections and some fixes under dash. The last I encountered japanese monster like this was a 1987 subaru.

@gabrielolivera7622 3 года назад

Well I replaced all 8 of my relays but it was turning but no spark. I’m going to restep the process and take off all harness connections and relays and replace and try a crank again.

@Agirlandherpuppys 3 года назад

Question Aaron...our ‘06 Armada won’t start, it just clicked loudly. We had lights on dash and everything inside the truck, so we didn’t think battery. We’ve tried to jump it just in case. Originally when the issue began, we swapped relays and it cranked and cranked after putting in a brand new one, but then wouldn’t crank again. I ran the IPDM self test this morning and it didn’t go through everything like it was supposed to. Now I don’t have the dash lights anymore or the click when I go to start. Any ideas?

@ibtowman 3 года назад

Good video! I'm having a issue with my 06 titan. Sometimes while driving I lose power to the gauge cluster and the engine loses power, have no response when pressing the gas pedal. Headlights and taillights stay on and within 5 to 10 seconds everything comes back on and works normal.

It was the idpm ecm relay. Nissan has a recall on it. I never took it to the dealership to fix. I ordered the relay from ebay and fixed it myself. Think it was a $8 relay. It's located in the box between the battery and firewall on my 06 titan

hi! I've a Nissan Nv300 1.6 145cv x82 2017 (van), and since some electrical problems I had with the charging system back in december (fixed), my front wipers are not working. According to my mechanic, he tested the wipers motor, the relay and everything seems ok... he saids that may be some electronic module... so I really want to do this IPDM selfcheck. The problem is that this VAN has not any "door" button that you can just press. Do you know how to do it in a VAN without this simple button? Ntw Thanks a lot for the video!!!

@yungavalor3192 2 года назад

Aaron Hines I have a question. When I go to turn my car on my fuel pump won't kick on. I tested the voltage of my fuel pump fuse and I do not seem to be getting voltage when the car is off or when it's on. But I didn't get to see what the voltage does right after I turn it on. Do you know when the fuel pump should have voltage when I turn the car on (not start it)? Like would the voltage normally show up for just one second while the pump primes or should it constantly be showing voltage? I'm trying to determine whether I have a bad IPDM or a bad fuel pump. Thanks.

@blufie 3 года назад

Good video. No one else mentions 12V at the MAF! I DONT' have 12V (4.5v), and swapping the relay made no diff. Is the IPDM replacement my next option or is thereanother work around to rule it out? (have the white original one). The self test powered everything up as expected. It would be worth a donate to your channel for assist. Thx!

I have an '04 Infiniti QX56 that has loss of power issues during driving. Not a complete loss but still has enough power to get off the road. But if I step on the throttle to pass briskly, the vehicle won't upshift and RPMs won't increase. Acts like bad O² sensors. But if I pull off the road and turn the vehicle off and restart it,it drives ok as long as I don't get heavy on the throttle. Is this an example of a bad ECM relay? Thanks for the video and any more information.

Of course after it is passes all the Diagnostic tests? If not then most likely IPDM needs replacement?

So I grab a used IPDM for my 2007 Titan because there is no power from IPDM to condenser fan..... I installed this IPDM, great to see the fan works great now but not without sacrifice.. my junkyard IPDM, will not energize my lowbeams, I learned this the dumbass way when later when it got dark i notice my bright new LED upgrades aren't present on. Highway signs and road ahead.. I get a IPDM to fix a problem that comes with its own problem,..Titan and armadas aren't abundant in my local spots.. this was the only IPDM available.. I am just going to order the upgraded newer IPDM.. no more salvage modules.. always a flaw, had similar experience changing a Dodge tipm.. you know...Chrysler's equivalent.. troublesome power control ... replaced one that wasn't engaging ac..That one had all function except left lowbeams.. dontget used tipms or ipdms.. always another dead function.. I swear..
