Yeah the lights are working on the remote. New batteries, i know the remote buttons are working,
so its one of three things.
- the remote is wrong frequency for my car,
- the remote is not sending out the signal properly.
- there is a problem with the slcu in the car.

Given the price of remotes i don’t really want to buy one on a gamble it may or may not work.
maybe, i need a 315mhz remote, or maybe my 433mhz remote is not sending the signal properly.

which is where some input from some aussies maybe helpful to make sure i know what the Aussie market cars and remotes should be.

After i check the module on the weekend if i am still having issue i will ring some wreckers and see if i can get one or two to try but i know getting parts is likely going to be a PITA.

Ok, so, i took out the boot trim to access the SLCU.


does the 315 on that mean it would be 315mhz?
that would match what the antenna on the window looks like.

also what is this connector?


just sitting down near the slcu and fuel drain hose

 

BC is the only one for Australia on paper and yours is a BB

FCC is American Federal Communication Commission

BB is on the list for USA models and 315 was the early frequency in the USA before changing to 433

my 1996 VIN serial # is X and works with a 315 FOB

In the morning I can look at my SLCU and see the label with pictures

The picture may appear upside down in down under to you so you would have to flip your screen around

 

interesting the car is a feb 95 build and if this is an American SLCU then it a pure coincidence it was replaced with a feb 95 build slcu.

but yeah definitely looks like i will need to get a 315mhz remote.
all the info i can find points to 315mhz.

 

I see the white label date

Also the US on the white label

 

would be great.
and hahaha. I can certainly flip the pic upside down. Lolololol.

 

ok so,
no luck finding a 315 mhz remote here.

would it be easier to maybe swap out the SLCU for an aussie one that is 433mhz?
my concern with doing this is what may happen as a concequence.
i read something bout aussie cars having a transponder in the key whilst american ones did not?
if i did get one, and swap it in and then i ran into issues i assume i could just put the current one back in and it would just go back to how it is now.
i would have a guess by doing any of this i will lose my radio tho and without the radio code that is not ideal.

 

any Aussies able to help with part number on the SLCU and the frequency of remotes?
trying to work out what exactly is the best thing to do right now.
buying a 315mhz remote from US is expensive AF.
buying a new SLCU locally may give other issues i am not sure.

what part number should Aussie SLCUs be?
what frequency should our remotes be?
trying to determine if the SLCU has been swapped for a US one which would also bypass the transponder and immobiliser i assume

 

I can confirm that Australian models do have a 315MHz remote, number DBC11510. ( See attachment)
Does your car have an Australian compliance plate, located forward of the battery in the boot, underneath the plate stating build date.
Whilst you mention you have read all threads on this subject, did you miss my "Key remote solution" (See attachment)I have posted to the forum on many occasions.
It provides a cheap and reliable alternative to struggling with sourcing a reliable original style remote.
I have had this system in place for many years with 100% reliability.

Looking again at your photos, you are reading the details on the circuit board which shows FM433 and assuming this is the frequency,
The correct details are on the battery cover, which should show DBC11510 315MHz.
My original remote also shows FM433 on the circuit board, however the battery cover states the above.
You do have the correct remotes, but as I stated in my remote alternative article, age probably caught up with them.

i can't read any details on the remote battery cover at all.
need to find a wreckers with remotes that i can go and test one out before buying.

 

Attached photo of battery cover with very small text, may require magnifying glass.
Jaguar in large text then next line (smaller) DBC11510 315MHz

A trick would be to rub the FOB battery cover with some talcum powder , foot powder or tooth paste , or the kid next door

 

unfortunately mine is blank

 

Yeah i did see that post,
nd i may just have to go the route of installing an after market central locking kit.
that is a really good guide you have on that.
when doing that option does it still work properly with all functions of the original system? i assume the follow me home lighting on the 3rd push of the locking button? wont work? and the deadlocking on a second push of the lock button?
or would it work like the key does? where unlock and then lock (turning key left then right) activates the deadlocking?
would holding the lock button the act the same way as holing the key turned and close windows and sunroof?
or is this stuff controlled from other wires in the lock?
i assume you could also wire it in to the boot release wiring tho and have remote boot popping

and yeah build date is 02/95 and AU compliance is 06/95

 

So i will be going down the route of wiring in an aftermarket keyless entry to opeate the lock and unlock function as the key does.
my question here is two fold.
i am buying a remote that has a boot release button on it. now which wire should i wire this into to pop the trunk? the one i have marked as 1, 2 or 3? or any of them should function the same?
i am thinking not to use 2 as that would become inoperable if the car was in valet mode?
my guess would be 3 as that is the signal direct to the relay to pop the trunk and therefore operational even when the car may be in valet mode.

also @John Herbert in the guide you made and linked above you listed the lock wire as orange/green. the wiring diagram lists it as orange/yellow.

 

I was at the salvage yard a couple of days ago but was unable t see the SLCM ( part # for USA ) on the other X300 cars , will look at mine again as I looked at it a couple of years ago

Researching your last post

You mentioned that you have a key on both left and right fwd doors and the print you chose does not reflect that

Yours may be Rest of World

 

there is 3 wiring diagrams for the central locking, LHD, NAS and RHD. all 3 of them show the wiring colours the same and none of them show a passengers door key barrel.
the door lock/unlock wires should be fine.
it ust the boot release i was unsure best to use. but pretty sure the one i noted as 3 would be the right one.

 

You are correct. the lock wire is indeed orange/yellow.
Sorry for that, I do actually have it pencilled on my wiring diagram as orange/yellow but for some reason inserted it as orange/green in the actual article, which I have now corrected.
