Can s90 seats be fitted to S60

[AnttiH31]

Yes, you can. The heating and ventilated seats are controlled with the same LIN slave module and it's not even connected to the seat module. 
Yes, you can transfer them from your old seats to the new one but you should also transfer the seat controller(s) otherwise, next time you connect your car to VIDA, it will detect them and force you to reload PSMD and PSMP. 

If the new seats have seat massage and side support you just need to wire positive wire to PIN 15, that's it 
You will need these for pining. https://www.amazon.com/dp/B0CH15J4BJ?ref...asin_title

Thank you for the reply. Do you have any pictures/info on how to replace the seat controllers? I’m aware of how vida will detect it. I’ve just thought that I would disconnect both seats before taking the car in for service but if the controllers are interchangeble, then maybe it would be better to swap them.

I live in the EU and consumers can’t access VIDA here :/


I’m also quite new to vida functions for the aformentioned reason. If the dealer reloads PSMD and PSMP software, what happens after that? Would they work the same but VIDA wouldn’t act up when connecting the car to it?

No, sorry. I do not have any guide for removing / replacing the seat controller. But it's under the seat and looks this. 
Yes, you could disconnect the seats before visiting the dealer but then you would receive DTCs for Airbags, seat controllers and etc. The service could just plug it in and connect to the VIDA.  ( you should tell them specifically not to do that. However, the person you talk to and the person who does the actual work are different)  In my case, they just ignored the note on the work order. 

VIDA would detect every replaced ECU. Some of them are interchangeable and VIDA just reloads the software depending on if the replaced part number is listed for your VIN. But in some cases, the replaced part is not listed for your VIN and VIDA would not reload it, " Incompatible Hardware" although it just works perfectly fine. 

The only way I could find to somehow determine if VIDA would load or not is that, search for the part number of the replacement unit on google. 
Check the official volvo part stores.  If the part number itself (replacement) or one of its (replacement) supersession(s) fits your car, the VIDA would reload it.

Okay!

So if I rip the seat controllers from the new seats and replace them with the ones I already have, then code in seat ventilation with OrBit, it should work straight away? So the ”brains” would be transferred over and the car would just read the new seats like the old ones? Then I’d just need to revert to the factory setting in OrBit before taking my car in for service? If I’ve understood correctly, all seat types have the same controller but just with different software.

The seats I currently have are the R-Design ones which have everything that the ventilated comfort seats do except the side bolsters and massage?

[IMAY2023]

Ok, I just pulled out the seat controller from my original momentum seats. It's pretty. Disconnect the cable connectors, remove the two screws and slide it down. 
As I said, heated and ventilated seats has nothing to do with the seat controller (PSMD / PSMP). It has its own LIN controller connected to the CCM (climate control) It has its own power supply.  You just need to enable   179 FRONT SEAT VENTILATION and that's it. 

Usually ventilated seats come with side support and massage. Look underneath of the new seats;  if there is a airbag and couple of pipes, you have massage seats too.

No, they are not.  I just compared my original s60 Momentum seat controller to the one I replaced from an s90 Inscription L (heated, ventilated, massage and side support). 
Controllers look exactly the same but there are missing pins on the s60 Momentum one. So, check yours too.

Ah, okay. So in the worst case scenario I would’nt have all of the pins in my current seat controllers. Wouldn’t this just mean that I could get all of my current controls to work + ventilation but not the side supports and massage as the pins would be missing?

Also, is there ant chance you could help me with the installation instructions in VIDA? Mainly on how to swap the airbags and how to disassemble the seat belt to get the seats in and out.

Yes,  but I wouldn't give up on side support and massage.  You can keep the seat controllers and before visiting the service, just disconnect the seat controller and not the main connector. So that you wouldn't get airbag light on DIM.  In addition,  you can attach a piece of paper, "DO NOT CONNECT"

Here is a guilde how to remove the back cover of the seat.  And here is another one, scroll down in the forum. 

how to disassemble the seat belt to get the seats in and out.

The seat belt is hold in place with one big torque bolt.  Easiest way to do it is, remove the four bolts that holds the seats. Raise and move seat further so that you would have enough room.  you will need leverage and there is not much space between the seat and the side pillar.  You can use battery powered impact wrench to remove the bolt.

Thank you so much for your help!!

I’ll update once I get the seats.

I’ve ordered the seats and they’re on the way. I don’t know for a fact if they have massage/side support but let’s assume that they do.

I’m a complete newbie on connector, pliers etc and I need more insight.

-On the seat connector, are the PINs numbered on the plastic connector or do I need to find a pin chart of the connector to know which PIN is number 15?

-What kind of crimping pliers do I need to crimp the PIN connector to a wire?

-How did you route the wire from the drivers seat to the fuse box? I’ve not removed seats from my car yet so I have no clue on how the looms are routed from factory.

-Looking at my cars owners manual, it says that Fuse 40 for seat massage uses a 5A fuse instead of 7.5A that I’ve seen on here. Which one is correct?

-The PIN connectors you’ve mentioned previously on here (https://www.amazon.com/dp/B0CH15J4BJ?ref...asin_title) are listed for 0.50mm2-0.75mm2. You’ve advised to use 18AWG wire which is 0,82mm2. Does the small difference matter at all?

Since the massage function is 1 wire per seat away from working, I’m keen to give it a shot.

-On the seat connector, are the PINs numbered on the plastic connector or do I need to find a pin chart of the connector to know which PIN is number 15?

Yes, the connectors are numbered but you will need to take picture and magnify it because they are very small. 

-What kind of crimping pliers do I need to crimp the PIN connector to a wire?

 I used small needle nose pliers.  Those pins are not widely used, I couldn't find traditional multi crimping tool for it.  Buying one just for that type of pin does not justify the cost of it. 

-How did you route the wire from the drivers seat to the fuse box? I’ve not removed seats from my car yet so I have no clue on how the looms are routed from factory.

After you remove from seats, you can easily pull the carpet if you want.  It really does not matter from where and how you route the wire.  There is only one thing you must pay attention. Make sure that there is enough free length of wire left under the seat so that when you move seat full back and full up, the wire is not stretched.  Route the wire from the connector (if you are pinning or from the tab point through the main main harness and tie the wire with a zip tie at the end of main harness where it goes under the carpet.  Basically make sure that the wire you are adding at least same length of the main harness from the edge of the connector to the carpet.   

-Looking at my cars owners manual, it says that Fuse 40 for seat massage uses a 5A fuse instead of 7.5A that I’ve seen on here. Which one is correct?

I used 5amp fuse as indicated in the VOLVO book.  Both front left and right seats are using the same fuse.  So, you can route one wire from driver seat to passenger and than tab it to the second wire that goes from the fuse box to the passenger seats.  I used these fuse tabs with 5 amp.   

-The PIN connectors you’ve mentioned previously on here (https://www.amazon.com/dp/B0CH15J4BJ?ref...asin_title) are listed for 0.50mm2-0.75mm2. You’ve advised to use 18AWG wire which is 0,82mm2. Does the small difference matter at all?

 No, I used 18awg wire with those pins.  You can also use 20awg if you like.  If you are not feeling comfortable with pinning you can also use cable taps like these .
