Seat Control Module
#1
![Default](/forum/images/icons/icon1.gif)
Been snowed in all week and decided to fix one of the postponed little issues. We seldom move the passenger seat and only discovered that it would not move a few months ago. It did work at one time in my ownership and had a '05 date so it has been replaced before.
Fuses #1 and 8 are good. Removed the module and opened it looking for the case damaged edge printed circuit. Found some blue/green corrosion at the Z1 diode at the suspect edge and it appears that it is open in both directions. Best I can tell the printed circuits lines are not damaged as I get continuity using sewing needles clipped to a VOM.
Haven't got a response from a car-parts.com query.
Anyone know of one of the module repair folks that might repair the seat module?

I think you can swap Driver's/Passenger's to check for proper operation. Back in the late 1990s and early 2000s I remember having to configure the replacement passenger seat modules in the driver's harness because the WDS would not recognize the passenger seat module. I called Tech Line and was advised to install it in the driver's seat, configure it and reinstall it in the passenger seat.
Swap modules side-to-side and see what happens.

Bob, thanks for the TSB. I put all your TSB posts in my Jaguar library.
Pulled the driver module today and the passenger seat works fine with it so the problem is clearly the module. While I had both out noticed that the VCAT extension was /100 on one and /400 on the other. I know the passenger module worked at one time in my ownership. Thought they had to be matched or can they be programmed by WDS / IDS? Both modules had dates much later than the car's manufacture date so both had been replaced by a PO.
I have replaced one on another Jaguar from a wreaking yard with a matched number and it was plug and play. Will it be if I find a mismatched /XXX extension? I have also replaced one on another Ford car for about $35. My module says Ford, made in Spain on it. Any chance of finding a Ford part match?

test point,
Modules for XK8's through 2002 were not programmable in the field, that commenced in 2003. The/XXX suffix is the specific software level programmed at the factory for market and application; i.e. RH, LH, Memory Seat, Non-Memory etc. To assure correct operation, you'll want to get a module with the correct suffix.
Cheers,
