Seat Retrofit -- New Module is throwing codes

[dalbreez]

Basically yes. 

If I had the original seat modules maybe I could just swap them in, and no need to install anything? But just risk the functions dont work?

Some modules have more PINs that others.  So, it's case by case, try and fail scenario.  Let's assume your new controller has the same amount PINs. Your original seat controller may or may not control the seat extension when installed on the new seats.  If the original controllers wouldn't control the seat extension, you could still enable it by using Orbit. 

Another point you have not mentioned. 
Your new seats with the extension, most of those seats are memory seats both passenger and driver.  You can verify this by looking at the seat motor connectors. If there are 4 wires connected to each motor, then you have memory seat(s). The additional 2 thinner wires are for the position sensor inside of each motor. 

This means that you could also enable passenger seat memory but you would need to replace the passenger door lock button, trim and do some simple rewiring inside the door panel.

Both of my old seats were memory seats (M1 and M2 in door panel, driver and passenger) and I believe had the same number of wires as the new ones before I did the swap (but hard to confirm). When I look at photos of the seat control modules online it does appear that they have a different number of pins. So who knows.....

At this point I'll probably try to download VIDA and download the appropriate software. Might happen in April. Thank you so much for your help, and if anyone else has tips please let me know!

I finally got around to this. Interestingly, when I loaded VIDA it said the same hardware changes that the dealer was seeing: 
TRM Remove
IMS Remove
PSMD Reload
PSMR Reload

I tried the TRM Remove, it worked and then I realized wait wtf why did I do this, my OEM towhook that came with the car no longer works! 

So I refreshed VIDA and then the 4/7 and 13 ppl app popped up. Sigh. Anyways, these installed fine but I spend $150 uninstalling and reinstalling.

As you predicted, PSMD and PSMR did not work. Error pops up saying the software is not compatible. 

From here, I have one of two options — either I find the old modules, put them in & lose the function of the chairs to update the vehicle, or I simply forego updating the vehicle.

Feeling frustrated with the process. Would have never swapped the seats had I known this would be the case.

If you still have your old seat controllers. 
You can try this. 

• Connect original PSMD PSMP, read out, order config test but not install it yet. 
  
• then connect the new PSMD/PSMP
  
• install config test
  
• after config test install, the PSMD/PSMP should be OK in the VIDA system, will not block Total Upgrade.

Sadly, the old control modules are are gone. Welp. I contacted them and everything but no dice.

I'm either going to have to just suck it up with no more updates (last one was in November 2023 -- seems like I've missed out on the window updates) or ill have to change cars. 

Too bad I've lost my VIDA access -- I've found a nice volvo nearby and I have the VIN but no longer have VIDA, so I cant see the list of options it came with. One of the most neat VIDA features I have to say!

You can get away with no cost other than VIDA 3 days subscriptions. 
You will need your original seat controllers though. Go to the same dealer and get them. Because even if you find the same exact seat controllers you use to have, VOLVO records have a different SN and HW numbers associated with your VIN. It will always mandate to do software reload before allowing a total upgrade. 

Without having the seat controllers, you can still clear all the others. 
1) Get a VIDA subscription.  $90 for 3 days. 
2) Before connecting the VIDA, revert the car to OEM and disconnect the TRM and IMS. 
3) Read out the car, it will give you HW changes (IMS remove, TRM remove,  PSMR and PSMD reloads) 
4) Order and install configuration changes. for $1.  This will re-read the car and update the VOLVO that all additional modules are removed. 

If you could get your original seat controllers, 
Basically the procedure is the same but with one change. 
1) Get a VIDA subscription.  $90 for 3 days. 
2) Before connecting the VIDA, revert the car to OEM and disconnect the TRM, IMS and put the original seat controllers back. (you don't need to remove the whole seat) 
3) Read out the car, it will give you HW changes (IMS remove, TRM remove,  PSMR and PSMD reloads) 
4) Order configuration changes. for $1, retrieve it  but do not install it yet. 
5) Remove the original seat controllers and connect the new ones that came with the new seats. 
6) Install the retrieved configuration change software. 



This will update the VOLVO servers with the new seat controllers and other added modules are removed. 
Do a clean readout again and HW changes TAB should be empty. 

The seat controllers would not bother you again but every time you visit the dealer or connect the VIDA, you must revert the config changes to OEM and disconnect the IMS and TRM.  


Do not believe those scumbags they simply want to rob you! They could not know if you need a replacement unit or not without trying to reload them first! 

IMS remove costs $35.  > You must disconnect the module. But as I mentioned above. Config change software should take care of it since you've already reverted back the OEM config.  
IMS reload costs $250 > This makes it official and here is no need for changing any module. No more disconnecting the module. Orbit will detect the new OEM settings. 
TRM reload costs around $90 > As far as I know, it's the same exact module for all models. You can install it and make it official, you don't need a new module. 
PSMR and PSMD reloads costs around $90 each.  > Here is the catch. You might not be able to reload the software depending on the part number. If the part number of the new modules are listed as compatible with your VIN. You are good. If not, VIDA will give you an error and won't install. VIDA will not let you know beforehand.  You must purchase and retrieve the  software first. But, you can always ask for refund, it only takes couple of hours or 1 day at most to get the money back.  

If you really want to know if it would install or not, 
Get the part number of the new modules.  Search the google and look at the official volvo parts web page(s). 
If your car's model and year is listed in "What it fits" of the part number itself or one of its Supersession(s), VIDA would install.   

Good afternoon. My car is Volvo S60 2024 USA. I’ve replaced two front seats. I had standard seats but then I installed two seats with knee support. Iэму also replaced two units - PSMD and PSMP. The seats work, the knee support also works. I also have used AUD and WAM modules installed. I want to buy a subscription to Vida Online and do the Global Update. As far as I understood from the information on the forum, I need to Reload the AUD and WAM modules. After that I should install my original PSMD and PSMP modules back and then do the Global Update.

You also wrote that it is possible to change the car configuration for $1, isn’t it? Can I install the PSMD and PSMP modules that are designed for seats with knee support, make an official configuration change? So that in the future, during subsequent Global Updates, I do not need to swap the PSMD and PSMP modules.

Can I Reload the AUD and WAM modules and then change the car configuration, so that the server has information that I have seats with knee support installed? Can I install the PSMD and PSMP modules from the seats with knee support (if necessary, Reload them) and then do the Global Update? Will the information about my configuration be saved on the Volvo servers? Or will Reloading the PSMD and PSMP modules download the software that was intended for me according to my VIN number when the car was manufactured?

First let's clarify two things! 
1) Software configuration change via Orbit or VDASH or something else. 
You MUST revert back any software configuration change before connecting the car to VIDA. Otherwise, the CAR's VIN number will be blocked by VOLVO for any software download and not limited to any ECU reload after the replacement of a faulty one. 

2) HW change such as ECU replacement or installing a module that did not came from factory such as IMS, AUD, IHU WAM. 
This does not block the VIN of the car.  On the contrary, VIDA detects all the HW changes and forces all replaced modules to be reloaded before allowing total upgrade.  

For the WAM and AUD. 
It's realy case by case depending on the replacement part number and the VIN of the car.  Since your car did not came with those modules, VIDA would detect those as HW changes and will force you to reload them.  You can purchase the AUD and WAM reload and try to install them but there is no guarantees that VIDA would actually install. It might give you an error message saying that "This software and HW is not computable with your VIN"  The risk is that, it will give you this error message only after purchasing and retrieving the reload software.   If it does not install due to that error, you can ask for refund and in most cases, VOLVO VIDA team issues your refund within 24 hours. (weekdays).  If somehow it installs the WAM and AUD, it will also enable the related configurations such as 360 view, and audio type.  

If it does not install, you will need to remove the WAM module, install your original AUD back and the install configuration change. This way, VIDA would clear any detected and recorded config HW change and let you to perform total upgrade.     

My advise, 
First, remove WAM. (disconnect the power), install your original AUD or disconnect the new one if you do not have the original and then try below steps for the seat controller. Once you clear the seat controller HW change after following the steps, run the total upgrade.  Below trick usually works because the seat controllers have many different interchangeable variants between the models and years and many of those variants supports common options unlike AUD or WAM which have total different options.   
  
For the seat controllers only!  
You can try this. 

• Connect original PSMD PSMP, read out, order config test but not install it yet. 
  
• then connect the new PSMD/PSMP
  
• install config test
  
• after config test install, the PSMD/PSMP should be OK in the VIDA system, will not block Total Upgrade.
  
• This workaround does not change any function configurations. It will only update the VOLVO servers with the new seat controllers so that it does not block the total upgrade. You will still need Orbit to enable the seat extension and other options you've enabled with the new seats.
