Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hi, my name is ***** ***** I will assist you
When you removed this relay, what happened? Did you have to force it out or did it pop right out?
Hi, Chad. I have ran into a few myself, unfortunately.
I don't think I'm going to have good news for you but I wanted to ask a few questions anyway
So when you removed the relay, did it require any force or did it just pop out?
did you notice any markings on the prongs for the relay? And when you tried to reinstall them, were they met with any resistance as if they did not want to go back in?
By markings, I am referring to any score marks or solder marks
Most of the relays inside the integrated power distribution module are permanently attached, meaning they are soldered or pressed in. It is for this reason that what you read on Google is entirely true. However, depending on your comfort level with electronics, it is possible to remove the ipdm and take it apart, soldering the units back together. This is a risky procedure, but otherwise you are looking at replacing the unit anyway. I have done this once before when a junior technician at my shop made a similar mistake and caused a no-start condition. If you do decide to save the headache and just replace the module, I would suggest using a salvage part from a junk yard as this will be much less expensive.
I can help you with the removal and installation procedure for the unit (which you have already done most of if you were able to access a relay) but I will not be able to help over the internet with disassembly and repair if you choose to go this route. I wish you luck my friend and please don't hesitate to ask if you have any further questions!
The next step would be to remove the box and look inside. It is clear that there is a poor connection, most likely due to a press-fit that was not intended to be removed, but it is possible to fix it.
Not a problem! It can be difficult to carry on a conversation in a chat room! I would not doubt that Nissan used a relay that is used in other applications, even though the setup used here does not allow removal of the relays. The problem is not with the relay but the box wherein it is not designed in a way that permits removal and installation of the relays.
In this case, Chad, I think the best option is to open the box and look around. I think that you may run into a very obvious, simple repair and maybe even learn a thing or two in the process!
At least this means you are able to do the disassembly part without much difficulty...and you also should be able to discern visually what the problem is. I think you will find that it is pretty obvious.
The only suggestion I will make is to make sure you disconnect the battery terminals and leave it that way for about 2 or 3 minutes before continuing and of course make sure the key is out of the ignition before you begin. Other than that, have a clean, dry workspace with plenty of light and don't lose any parts! :-) Good luck!
Awesome bud, and you are very welcome!
It is ok, we can get back on it tomorrow.
ok no problem buddy, I'll get with you tomorrow. Goodnight
Those are probably the most difficult relays to remove on a car, Nissan was being a jerk when they designed those. The only advise I can give you is to use a small screw driver to release the locking tab on the side and keep pressure on it while you are pulling it out. You may try to pry it from the bottom to "break it loose" before you actually pull on it. Once it comes up a little bit, the locking tab should stay in the released position.
That's the approach I would take, man. I know it's scary but hey, you can't really make it worse. It sounds like you are doing it right from what I remember about the disassembly. Good luck buddy.
Hi, I'm sorry I just got home. I was talking with you from work. Why don't you send me a photo of what you are working on. are you able to do that?
And you say that when you pulled out the throttle relay and reinstalled it there was resistance, but it went in and then from there it did not recognize the throttle response any longer?
You are right, man, it does look like they can be. It clearly says in the owners manual that they are not to be tampered with though. When I ran into this problem in the past, though it was not the throttle relay, I found that the female pins for the relay were damaged from where the relay had been reinserted. Those female pins were soldered to the board and had shifted during replacement of the relay. I had to solder it back to the board and the problem subsided
If there is no damage to the board, the female pins or the relay it makes absolutely no sense that the relay removal and installation was the problem
Was there anything else that went on other than the relay swap?
When you made the relay swap was the key in the on position?
Chad, if you don't see any problems inside the ipdm, and nothing else has occurred other than what we have talked about, I am afraid I'm stumped. I am sorry that you spent all this time going through checking inside the ipdm based on my recommendation, I was sure that the issue would be in there based on my previous experiences with them. I will back out at this point and hopefully another expert may be able to shed some light on the problem.
