How to remove memory from key fob
#21
That's what mine looks like....exactly the same. Yes...I did wonder about that myself...but it must be correct.
On another thread...a Member rigged up an aerial directly from the security module (where the other end of this cable is plugged in) in order to by-pass the existing aerial and cable in order to eliminate any potential faults or breakages in them.
My fobs don't program at all...no chirps...and only the light flashing near the gear change when the light stalk is pulls 4 times...but not when the fob buttons are pressed. At least you are further ahead than me! Lol!
Best of luck!

It might not be correct Andrew, they might both be broken off
There were no audible chirps from mine ... only the light flashing ... and it only flashed on the occasional press with the fob almost touching the rear screen.
For other peoples benefit in future ... it was counting the flashes rather than the presses that was important. Five flashes spread over whatever number of fobs being programmed.

2003 Electrical diagram:
Fig 13.1 has the antenna coax schematics:
There is text, too:
This suggests this is a traditional coax cable. That coax plugs into the control module in the trunk. Probably fairly easy to check what the other side of that coax looks like, and make a determination one way or the other. On the face of it, that "center pin" is missing...

I think the two connections are meant to be insulated from one another on the two elements of the stud ... The other end of the cable has a high quality coax aerial connector on it ... with two connections ... an inner and an outer.

I've been working on this short range problem on mine too and can assure you that it is a coax cable, connected in the normal fashion at the security module end. At the aerial end, the centre core wire is indeed connected to both of the tabs on the screen, while the outer sheath is connected to the ground point that is on the roof itself (in the coupe). That ground point is about 2 or 3 inches inside the roof liner. Easily seen with a torch and a mirror.
At the module end you can check between inner core and sheath and you should find open circuit, Also check that the sheath has a good ground reading that proves the roof ground is good.
As for the convertibles, it would seem that they depend on the module ground alone.
I've also been inside the module where I found it in as-new condition, as were the three multi pin connectors.

It is indeed a conventional coax cable from the SL(C)M, and has a 'proper' FME coax connector at that end. However, the connection to the window glass is a simple stud. The ground at the antenna end is made separately, so there's no need for anything more elaborate. Unfortunately, JTIS doesn't help by describing it as a 'coaxial connector', which it isn't.
The layout on the rear screen just makes it look like a dipole arrangement...
This pic. courtesy of Doug Dooren from the MKII/XJR forum explains it best:
Convertible is different, as astro notes.
I have no fob range issues.

Well I guess that would be the Security Locking Module.....not really a sensor. Unless there is another "sensor" that they replaced? Be interesting to know in case this might be causing key fob issues for other members (including myself).
Anyway, I'm very happy your issue has been resolved.
take care
