Hi!
Stupid me! I was istalling the PAC unit, which my friend carried out from US.
Probably smth. happends (circuit or smth!) but now, neither the radio is wornkig, but also the climate control!
The front panel is not lighting at all!
The display (OEM Yellow on) works fine, but no information from RADIO is shown.
It shows temeperature and other stuff.
When I connect Radio, then it shuffles with CD's insisde, so I think, the radio is fine.
The fan is not working as well, althought, I thought it was wornkig.
Non of the buttons on front panel is wroking!
Help ... is there any fuse I should check?
I have a very bad feelings, that something burns out at the front panel... and this will be VERY problematic in my situation, since I do not thing, I could get that by the dealer in Poland :(
ADDED:
Welll ... this is funny:
1. The panel lights are working (while lights turned on)
2. Eject button for TAPE and CD is working
3. Rear defroster button is working (and it shows on display as well)
but non of the radio control buttons, clock, maitenance, and non of the climate control knobs as well as buttons is not working.
Buttons on steering wheel are not working as well.
I can not turn or turn off the radio.
Diagnostic mode for lights (???) PREV + MUTE/PAUSE is not working as well.
Clock is not shown at all, and now all temeprature values are shown in F instead of Celcuis ..
Any idee?
The panel part number is 28395-CA105 Calsonic Kansei (if i'm correct) probably unreachable in Poland.
But even I could get it ... how can I be sure, that thats it?
Heeellp ....
Best regards, thank's in advance for any ideas what to check and help...

matik-
My only suggestion is to retrace your steps and make sure all connectors are properly seated. You should also check the fuses to make sure none have blown.

well ... I think all checked a lot :(
I was mounting and dismountig this several times, with detail checking of all connectors, and it seams to be fine.
I've checked as well the fuses (two in cabin: booth ele parts, and one under the hood: radio) and they are all ok:(
I do not know, is there any other fuse, which secures the electronic mentioned above (instrumental panel).
To the panel, there are two connectors comming:
One, is comming from harnes, and second one is comming directly from radio (small one, like a band).
There is no possibility to connect them incorect :(
Does anybody have an electronic schema of this, or knows, which pins on connectors are which funnctions?
Sinnce fallow function works: rear defroster, lighting when lights are turned on, ejecting of the tape and ejecting of the CD, I think some of the panel functions are working.
With the bigger connector the power is delivered probably, and these functions, are probably beside of all electronic on this panel. Otherwise, it will not work.
If there is no additional fuse, then maybe there is just one element which burnes out.
Having electronical schema, I could have check all elements, by electronician, and just replace this on ... if it is not some kind of CPU or memory chip sitting on the panel ...
There is one box contaning some electronics as well under the radio, with three connectors (i think there were three).
I think, this one is for climate control separately.
I hope this one is not burned out as well ... :(
I am very sad ... my wive (which is driving now with the car) is really angry with me ... ;) and I think she will be much more angry, when she will find out how much it will cost (wihich I think will be not cheap:( ).
May I ask somebody of you, to ask a dealer in US (since in Poland they do not have expierience enought), what can it be, or/and how much will cost this part ?
Thank you for all your help

You need to figure out whether its the PAC that is causing the problem, or a connection you might have forgotten to plug back in.
Try disconnecting/removing the PAC and putting it all back together.
1) If everything returns to normal, its the wiring in the PAC.
2) If things are still busted, its probably a fuse or a connector you forgot to plug back in.
Until you pinpoint exactly what is NOT causing the problem, we can't really help you figure out what IS causing the problem. Throwing parts at it will not help.
Good luck. |

So, what I did:
1. Removed fan panel, to get access to display and screws for radio unit.
2. Removed plastic cofers at booth sides of radio, to get the access to screws for radio unit.
3. Removed screws of radio, to slide it out.
4. Then, stupid me, I've remofed the front panel, which was connected with two conecotrs: one from harnes and one from panel to radio (like a band).
5. Then I've connected the PAC unit, which was unable to connect different way then described in manual (because the plugs do not match different way).
6. Then I've tested by playing from ext mp3 player over the PAC unit the radio (the key was in ignition, turned to ACC). Everything was working fine, and as it was described in manual of PAC unit.
7. Since everything was working fine, I've stated to assamble the unit back. Stupid me. I just switched the key in ignition to off, but I couldynt remove the key, since the gear lever was on L (for convinance dissasambling of the unit), and it was unable to remove it.
The batery was on, as well, as I was hearing the beep signal of left key (the doors was open).
8. While assambling, I was focused on one of the screws, and I noticed (which I'm not 100% sure), that the radio unit, toutched te back of the panel in the area where the power/volume buttnon/knob is (at the back). Then, I think there was a small circuit.
9. I've assambled everything, and then happends that:
- non of the knobs/buttons on the front panel was working,
- only buttons for ejecting the tape and CD was working, as well as the rear defroster was wroking (but it was not confirmating with light, that that one is turned on).
- the lighting of panel was working.
10. After noticing that, I've removed the PAC unit.
11. The problem still presist.
12. After that, I've checked all fuses: two in cabin area, and one for radio under the hood. They were all ok.
13. After removing then, and turning everythig on, the display shows in Fahrenheit, and it forogots the temperature settings which was before (this can be regognized from the fan speed after starting the car, before I've taked out the fuses, and after that).
So now the situation is, that the PAC unit is not connected, all connectors are correctly connected, when using the tape, I can hear the music, but without any control from panel, neither from steering wheel, I can eject tape, eject CD, turn on the rear defroster (without led showing that is turned on, but with the icon shown on display), no control over the climate, and no other control over the radio, as well as the clock is not displayed on the display, and the other buttons (maitenance, trip and so on) are not working (as well as none of the climate control, besides the rear defroster).
I'm like almost 100% sure (if you think as well) that this "motherboard" of panel, is burned out.
I do not have schema (maybe someone from you does: please provide if possible), so I could check the electronic devices on this board by electrician, which one is burned out.
Since some of the functions are working, I am assuming, that not everything is destroyed. Maybe it might be fixed, just by replacing one of the components by the board (just like they did, after my laptop was dystroied after a storm, when they replaced some of the chips/components, of the motherboard).
What I'm afraid of, is that this box (under the radio unit, which probably contains the climate control functions) is not busted as well. This will makes me more troube :(
I do not know, is there any other fuse, I could check, which is responsible for the panel (hope there is any), but I do not think so :(
I hope, I described it a litte more in detail, enought for you, to help me .
Best regards

I would
1. Return everything to the origional condition as it was befor the PAC installation ever started.
2. Also, remove ANY other add ons or accessories that you may have installed.
3. Take the Virgin condition car to the dealer for repair. |
|
|
| matik |
Well ...
Everything is in oryginal condition (right now).
There is no add ons, additionaly (besides this PAC, which is not installed right now).
My dealer will not help me probably, since this is a little different then in US :(
I mean, I will ask them anyway, but they will probably say to me, that this panel is broken (which might be true) but most sure, they will tell me, that they can not find the problem, since is to complicated ;) and need an electrition to check on this, or that this is an US model, which is not supported in Poland ;)
Or ... they will tell me, that I need to replace this panel, which I need to pay for it, even, that this is not that, what might be broken :(
And I will have to pay for it (and it is not cheap, I saw in internet in US, and if it's that, it will be around 400$!).
Does anybody has a detail description, of the fuses which are located under the hood, on the passanger side?
And instruction how to get to them withoout any problem ?
Since there are fuses for ENG CONT (Engine control I supose) I do not want to remove them (for checking) unnecesarly to make it even worst then it is already :)
Best regards and thank you for any help

There are a lot of wiring diagrams, and I'm not sure we can post enough of them for your needs. You can download the Factory Shop Manual from www.nissan-techinfo.com for $20 I think. |

Searching threw the grat forum, I found one picture, which might be helpfull as a additional description for the problem, which I've caused by my "joyfull" creation;/
Oryginaly posted by jaak, in post:
http://www.nissanmurano.org/forums/...rs&pagenumber=3
Hope the jaak will have nothing agaist, that I've used his picture, with my additional comments.
This one pinpoints the location where the probably circuit happend, as well as the box (climate control) which I'm afraid of is broken as well.
And also the connectror, which If You might share, what the pins does mean.

Ericks Suggestion
"There are a lot of wiring diagrams, and I'm not sure we can post enough of them for your needs. You can download the Factory Shop Manual from www.nissan-techinfo.com for $20 I think."
Is a good one. You can download over the internet and pay with a credit card. It will have a lot of detail as to what is need to do this yourself.
DO the models in your country not have the same panel? If so they have to know how to support it. If not There are countries in Europe that do. Is the Car Drivable.
Look you are in trouble here nd like it or not it will cost some to fix it. If you "broken" some intergrated circuit you will probably have to replace the Head unit. Yo must ultimately decide to finde a electrical technician to work on the unit or replace it. Do you even have the necessary test equipment to determine what is broken?
I am sorry I have no suggestions better than: To get the wiring diagram if you wnat to keep trying yourself and to get an assistant to help you otherwise take out the head unit and ship it to a friend in the US for fixing or buy a new unit, |

If a short circuit happened because of a human mistake, there is certainly no fuse blown but rather circuitry damages.
It is a little late to hear this but you should never attempt to dismantle the head unit when it is still fed with DC. In fact, to install a PAC, you do not need to dismantle anything at all. I have done it many times and it is clip on so there is nothing to blow.
I don't know how you did what you did but no one here will be able to tell you anything else than to put everything back together as it was before you touched it and pray that it works. If it does not, and I guess that your MO is not on warranty anymore so you can try eBay for a new head unit (including the climate controls). I have seen a few from time to time on eBay. Otherwise, you'll have to contact the junkyards. |

Its kind of difficult for the guy since he has a US Murano in Poland, and Europe uses a different climate control panel (so the dealer probably cannot fix it).
In either case, best bet would be to get the factory shop manual and see if it gives you any clues. Good luck Matik. |

Thank's Guysfor your help ...
I think, this is what I'm gonna do (download the manual).
It was not my intention to repair it by myself. I do not have enought expierience and knowledge, to mess up with all chips, capacitors, resistors and all other stuff you can find on this plate.
The diagrams and/or schemas was more for some electictians, which I wanted to deal with it. Since it might be more helpfull for him, not for me :(
It could give him a clue, where to search for a broken part, since this is probably not so popular, to deal with such a "motherboards".
Just one more question: by Factory Shop Manual for 20$ you ment Service Manual Book? Can I download it? for 19.99$ is just a one day online subsription ... I don't think, it is possible to dowload it ...
To buy it, its like 300 smth dollars ....
Am I correct?
Best regards

Matik,
yes, the $19.95 subscription fee gives you access to all manuals and you can download them freely. However, a word of warning - the schematics you are looking for are not there. You would need a different manual - and I do not know it it is available at all.
Before you do anything - remove the PAC unit and return everything to the "normal" state, I mean how it originally was. Then try what is working and what is not. Start from there... |

matik,
If you had that panel opened up as shown in your post and touched it while the battery was connected, then you are SOL.
I would suggest that you start looking at ebay for a complete replacement. They are actually selling for not too high of a price.
good luck.

1. Numerous folks have said put it back to origional.
2. You Have said it is and the problem remains.
3. IT is pretty evident it is not a connection but a circuit component problem.
4. You need to get a new Head end to fix it.
5. after you get things back to normal really thinkif you want to try again.
My advice is no. Go Luck! |

Ok ....
So I've spoked to the dealer. They told me, to get this panel oryginaly, I need to pay for it 2500 zł (which will be around 892$ !!!), and I can have it in aprox. 3 weeks.
This is much more expensive than that, what I've found in internet in US (357$ on http://www.trademotion.com/partloca...M&siteid=214102 with part number 28395CA105).
Therefore, is much more better, to buy it there, and get shipped even with UPS.
Now, one of the guys by the dealer, is an electrictian, and he told me, he was dealing with such a kind of electronic several times. He told me that what I was thinking as well, that unless no company programed chip is not destroyed, it might be possible, to get it fixed, by replacing the broken element.
He told me, he might have look on that, and can take it over night, to get it checked.
If that will not works, there is one more company I found in Katowice, which deals only with electronics in cars, including computers, airbags controllers etc.
The guy said to me, exacly the same, that they might check the unit (which he said might take just 5 minutes, or even a week, because without having a schema, they need to go step by step, and redraw it), but he can not promise me (from the same reason then above) that they will fix it (as minimum, they will not charge for not repaired thing :)
I will let it check. I do not want to buy new unit, unless I'm not sure, that this is not it ...
Othrewise, I can buy a new one, install it, and because fault presist somewhere else, it will not work anyway, or it will burn out again.
I will keep you posted how does it looks like.
Maybe, while the guys will go over this unit, it will be possible to get the redrawed schema from them, and posted it, since it might be interesting for the future...
Thanks for advices
Best regards

Well ...
Finaly the issue is solved. The man has to pay for his mistakes:)
I've ordered a new panel in US (thanks to my friend who did that for me) and get it shipped to Poland.
I've replaced the panel, and now everything is working how it supose to be.
My doubt is, in that panel, the microprocesor is just burned.
Maybe, I will give it to my friend right now, to play with it a little, and find out what was really broken.
Curently, I'm dealing with another issue ;)
Since I've connected the PAC unit, and it seams to work but ... I hear the sound only in left side speakers ;)
I think, only the connector might be loose ... but, if you have anny suggestions, I will appreciate ...
Funy thing is, when listening to radio, CD or TAPE, the sound is comming normal over all speakers ...
best regards
