Passenger Seat Module -

[PTR200Jag]

The seat electrics don't work on the passenger side. When I picked the car up just over week ago the previous owner told me this so it was not a secret

When I looked under the seat the module was hanging by the wires
Looking closer the module itself has been ripped or levered off the seat.



The plate is supposed to be bolted to the module then the plate to the seat..
This is what is left of it;



As a matter of interest the electric headrest appears not to be wired directly to this module and works independently of it when the seat back is tilted... although the height adjustment IS connected?

I took the drivers module off (to substitute test) and found it with one side of the bracket ripped out, so I eased the bolt head and bits back together and got out the glue ! Not pretty but unless you are lying in the footwell, upside down, holding a mirror and peering through a slot.. you won't see it!

With the driver one connected to the passenger seat (they are not handed) and the controls now work, so the passenger module is duff.
A visual inspection reveals nothing amiss on the circuit board and I can't check much more than that because of lack of specifications.

What I do know is it is a Ford part number 1w8f-13c789-ab with a Jag part number LJE2160AB/XXX

any one got one to sell??

[PTR200Jag]

I have established that there are some different modules that look exactly the same but have different codes on.
The crucial part to the code, assuming the first part is correct is after the forward slash... so in my case I need a LJE2160AB/XXX...... the XXX seems to have a code of 001- 004 how do I determine what mine is?

I have also found some that have similar codes LNC2160AD off the XJ8 which fits anything upto 2003 model...
They look exactly the same externally with the same number of pins in their plug sockets.

Anyone tried these?

Some more information has just come to light

Apparently there is a code on a "Vcats" sticker in the boot on the left hand chassis rail under the carpet.

I have just had a look and the drivers side module has a different suffix to the passenger side.. drivers 003 and passenger 004

These codes are programming codes... so presumably they have a some different functions, each seat, that is.

What I do know is that transferring the drivers side module to the passenger side got the seat operating in all functions.

So the question now is how do I determine the suffix code off the ACTUAL module when it is shown as "XXX" LJE2160AB/XXX

Or does it REALLY matter?

In a further update it appears that the modules are vulnerable in the location under the front of the seat, they do not sit far enough under the squab and either get kicked off or jammed on something left under the seat.
They are absolutely loads of broken units and people reporting finding them broken when they investigate faults. The casings also seem "too tight" as reports of chaffing the board are consistently coming up on forum discussions. Some investigation of the possibility of relocating these units further back under the seat is warranted.. anyone done this?

[PTR200Jag]

I can find no fault that appears to be repairable on the circuit board, i.e. no dry joints/ missing connections but I have found a burnt out resistor,,, or what appears to be a resistor so in the meantime I seem to have got a little further in my quest for a seat module in that I am told that there are modules for the early non headrest seats and ones for the later electric headrest versions.

It would appear that I can get any variation on the LJE2160AB where the "XXX" equates to 001 -004... I cannot, still, determine which code they are by looking at the labels so I suspect this may be a Jaguar only access.
However, now I have been informed that apparently "neither passenger nor driver side" module is relevant and it is possible to use either /or.

I am about to find out because hopefully I have the correctly coded s/hand unit on its way to me.

The plan is to remove the passenger side unit, which I will re install in the drivers side (originally on there) and put the "new" one in the passenger side, when it arrives.

Hopefully I will have fully functional seat movement !

Did the 'new' one work PTR200?

[PTR200Jag]

Did the 'new' one work PTR200?

err, still on its way to me so I am informed expected this week !

will post updates as soon as I have re installed the "drivers" one back on the drivers seat and installed the "new" one on the passenger seat.
This is only to prevent any possible problem with the "new" one having a fit and causing a problem on the "apparently programmable" drivers side

Off to have a look for the cabin filter now

[PTR200Jag]

always happens... mention its on its way not expecting it for a few days and its ARRIVED !



Old one on left, new one on right, old manufactured / checked 28/01/02, new 02/10/02 and checked by the same person!



Got outside early today, thursday, sunshine and marginally warmer with no wind as such. Got the doors open, left the boot open AND THEN disconnected the battery !

No dramas re taking off the module on the passenger side (to put back on drivers side where it came from) except to note that it is impossible to get the module off when the seat squab is down at the front by more than halfway.. it needs to be put into the highest mode, at front, to get really good access and be able to lower the module from its mount on the seat base.

That suggests that if the module fails with the seat in a front down attitude then it is almost certain the the module will have to be broken off the mounts... unless there is a way to manually adjust the seat that is possible to get at such as mentioned in the seat refurbishment article in the December 2014 JEC mag.

The cables are very short to the modules and it requires some manual dexterity coupled with head in the footwell, torch in the mouth juggling.. and the M6 nuts that hold the module to the seat are not in a great place for access!!



Anyway, the good news is that the "generic" module that I received works perfectly in the passenger side seat. Result

As a bonus I also found a £1 coin, 10p coin and a 50 euro piece under the seats ! plus a Christmas tree air freshener, several sweet wrappers and another unknown coin that disappeared into the back somewhere never to be found.

Hello all.

This seems to be a familiar story for myself and other members of my local JEC. My 2003 XKR had a XJ8 module fitted beneath the passenger seat, neither the seat heater or the door mirrors extension functioned. It is the seat modules that control the door mirror pods folding in and extending out functions.

The good news is that I found a replacement from a very helpful second hand parts company in Ilkeston, Derbyshire. I travelled to them and they let me 'try before buying'. Unfortunately, on the way there, the driver seat module malfunctioned (Seat back went back and could not be brought upright). They had only the one module at that time, but as soon as a second became available I journeyed up and purchased it. Both seats functioned normally.

I have made a spanner to release the nuts of the mounting strip, finger feel only though. When I bought the car, both modules were attached to the seats with cable ties and both casings broken as in the photos.

I have noticed some very suspect conductor strips on the circuit board of the original driver seat module and intend to attempt repairs. It would appear the later modules are harder to find than the earlier types and also more expensive.

As for the codes, I have found these not to be absolutely imperative, make sure you have the correct module for your car's seat functions. For mine with the headrests it is LJE2160AB/XXX (From MY 2000). For the earlier models it is the LJA2160AG/XXX (To MY 2000) module.

I hope this is of help.

Hello all again.

This is a follow on to my previous reply. Hopefully this will also help other owners of the notorious seat modules.

Firstly, I find that there is usually just 1 function that fails relating to the module. In other words, if the seat fwd/aft movement fails you still have the seat up/down operational. Here you will still be able to raise the seat. If the up/down movement fails you will probably still be able to move the seat in the fwd/aft directions to remove the front holding down bolts and slacken the rear. You will again be able to lift the seat and remove the module.

I prefer to secure the module as originally designed but there is the alternative of using a couple of cable ties. Don't put the ties round the round bar just up from the floor, the module can still move and may be crushed. Put the ties round the metal plate used for securing the module carrier that is just under the foam padding under the seat. It is relatively easy to push the ties between the metal strip and the foam. As has been said many times, double jointed wrists would be helpful!!

A bit more on the type numbers, the last module I purchased has the code LJE 2160AA/XXX and a label on the cover dated year 2000. I don't know from which type of XK the module was taken.

All the best, I'll post another reply if I have any success with the soldering of my failed unit. I can see broken tracks on the circuit board.

[Wheelspin]

I have what I suspect is the same problem - 1998 XK8 with an unresponsive passenger seat back, although everything else works. I’ve seen a long thread on a US board about a guy who can repair the circuit board with a soldering iron - is there anyone in the uk who can do the same thing ? Thanks in advance.

Try swapping the passenger and driver modules to check your diagnosis. If that proves the passenger unit is faulty, take the number from the module and contact BBA Reman (www.bba-reman.com) which is a company able to supply some Jaguar seat modules. Mike.
