Retrofit Memory Seats

Dave1987 · February 21, 2021

Hi guys,

So I have another thread about retrofitting a satnav into my 2007 S-Type Diesel XS, this one is about retrofitting 10 point memory seats into it.

The seats it came with had no memory module, so what I have done is:

Installed memory switch pack in the door handle
Installed door module
Installed seat with a programmable seat module

However, although the dash will ping and say "memory 1 saved" and "memory 1 recalled" the seats don't move. They won't even move with the switches on the seat itself. Is there a module I'm missing? Or does it need a computer plugging in to tell the car it has memory seats? I figured it would be plug and play, since the dash recognised the switch pack straight away. But no joy.

I have noticed some differences in the DM23 20-Way socket under the seat. But I can't find anywhere that tells me what the wires correlate to.

The Doner car has The New Car has

[] [] [] [] [R/W] [Y/R] [U/W] [N/O] [N/G] [] [] [] [] [] [R/W] [Y/R] [N/O] [U/W] [N/G] [N/G]

Doner New

[B] [W/U] [U/Y] [N/G] [Y] [U] [U] [] [] [] [B] [W/U] [U/Y] [] [Y] [U] [U] [] [] []

Do I need to move the Brown/Green (N/G) cable from the 10th pin on the top of the new cars DM23 to the 4th pin of the bottom so it matches the Doner car's configuration?

Also is there a way to tell from these pics if there are the wires for heated seats already in place?

Thanks

Dave

You'll need SDD to configure the car. Also beware of SRS warning light as occupancy sensors will need matching.

Dave1987 · February 21, 2021

Awesome, thanks for the reply Raistlin!

So all of the manual stuff is done, I can just get my mechanic to program it? I think he has the computer thing, hangs it on the steering wheel and plugs it in.

Can the occupancy sensors be configured from the computer too, or will I need to swap them over from the doner car? If they need swaping, where can I find them?

Raistlin · February 21, 2021

If you have the SDD both can be done at the same time

Dave1987 · March 3, 2021

Raistlin, wondering if you can still help?

So, I got the SDD and a mongoos cable, plugged it in to the car, made a connection, read the VIN, read the diagnostics and it came up with all those bubbles with green ticks showing whats installed.

The Driver Seat Module (DSM) is coming up as an orange question mark and I can't for the life of me figure out how to tell it the module is now installed.

Dave1987 · March 3, 2021

Update: I ran the diagnostics went to "Extras" and ran the "Configure New Modules - Front electronics module" and "Configure New Modules - Rear electronics module"

......now, as well as the seats still not working, my electronic parking brake light flashes and I get a message on the dash "Could not initialise parking brake" .....yay.

Raistlin · March 4, 2021

Sorry Dave, but if you're diving into SDD and coming up with errors I can't get involved any further because you CAN brick your car with SDD. I hope you get the fault cleared.

I'm not having a pop at you here it's just that I can't be sure what has been done now and I could make it worse.

Dave1987 · March 4, 2021

Ah that's fair, I guess there's rules about not being held responsible. lol

I've shipped it off to a mechanic, so hopefully he can fix whatever I've broken. He's not an auto-electrician though so I may need to track one down.

Raistlin · March 4, 2021

Thanks Dave. I appreciate your understanding 🙂

Dave1987 · March 4, 2021

Aye no worries mate, I will post here as the story progresses. Hopefully it'll help someone out in the future before they do the same as me.

Dave1987 · March 5, 2021

Okay update, the mechanic couldn't sort the Parking Brake flashing on and off. Said it might need a new ECM. I got it back today and figured I had nothing to lose running SDD again. I managed to find this:

The Electronic Parking Brake. So I ran that and now the brake works fine. So I swapped back the old seats that don't have the DSM installed and they work fine now. Getting it back to standard so I can sell her and I think I'm going to get an XF, rather than trying to install all the upgrades I wanted in this one. (Now that the government are offering 5% deposit for mortgages I have a bit more money to spend)

Hi David,

I have used the same system for few times.

Installing all the upgrades can be a real nuisance. When I bought my s type almost 8 years ago, I was able to discuss with a main dealer the bells and whistles that I wanted, and the dealer was able to provide a 2007 model at a reasonable price. I have not had any real problems.

The Government can assist sometimes! I have had the pleasure of not having to pay a mortgage for the last 26 years, which does help an impecunious pensioner!

Regards,

Peter.

Hi Peter, yeah I thought because mine is the XS all of the looms and such would already be installed and everything would be plug and play. It's just not that simple unfortunately.

Right now I'm looking at a nice XF (2010 3.0 TD S Premium Luxury) which has all the bells and whistles already installed for £6k. Going for a jag again because I just feel like they're a nice place to be inside, I don't need super sports drifting round corners. I just want to not have pot holes jerk my back and a nice interior. It also seems that the XF is more economical, even though it's a 3.0L it's reported as getting around 30 mpg whereas the 2.7L S-Type I have at the minute is averaging 19 mpg and thats without using Sport mode. Would be nice to get a few more miles between fill ups heh.

Well done on paying off your mortgage! That's the dream, nice car, paid off mortgage, family and a secure job. lol

Hi Dave,

My s type is the SE, and the first owner must have had a reasonable good back pocket. I checked all the factory fitted extras and they added up tp £11,984. Even a spare wheel, jack etc was fitted.

My employer used to deduct my mortgage from my salary and I forgot about it.

Regards,

Peter.

Raistlin · March 7, 2021

SDD works fine on your new XF 🙂

Jaguar Voice, for example, a ridiculously expensive option when new, can be achieved with three clicks of the mouse and NO extra hardware required Dave.

Pleased to hear your car is back to normal.

Yeah I had a 3.0L SE a long while back, that had loads of extras including the sunroof which seems to be very rare for some reason. Probably because fitting one after the fact is a complete pain. I had to move from that one because the sills completely rusted through. It's a shame because it was one of the last ones built by Jaguar before they started fitting Ford engines. But it was bought by a Jaguar Specialist who wanted it for his wife, he wanted to restore it.

Oh sweet that's what we like to hear. Just simple things to make like a little easier. I do like the lighting inside the XF too.

I'm more pleased, was having a heart attack for a minute there. lol
