Maybe the early BECM are different to mine ? He has a 1995, but I tested it on my 1998.

Another possibility is the GEMS ECU could have the security disabled ? (There is an LR bulletin on how to do it)

I doesn't make a lot of sense for the EKA to operate the way you describe but with JLR anything is possible.

edit: @pwood999 Having re-read your posts the penny has dropped. I realise you are not turning off the immobiliser when you turn off the EKA function. Petrol or diesel, that can never work.
Briefly, the sequence of events is as follows:- starting with the car locked. press unlock on the FOB, if the BECM receives a valid code, it enables the immobiliser function, the mobilisation code is sent when the key is inserted in the ignition.
Again, starting with the car previously locked with the FOB, open with the key blade, no valid code received by the BECM so the immobiliser function is not enabled. At this point the EKA code is required which in effect replaces the FOB code. If EKA is turned off, you are in the shyte at this point as diagnostics are required to turn the EKA function back on..
If EKA and the immobiliser function are both turned off, the sending of the mobilisation code to the engine ECU becomes automatic and is repeatedly sent when the key is inserted in the ignition on the diesel. With the petrol it may be sent only once as it's a rolling code but I have not been able to check that At no time is EKA required. The BECM is the same for petrol and diesel so I doubt there is any difference in the way the system works.

Ahoy all. so some time has passed.

i have changed the RF receiver to a Mk3 True Green dot.

the key fob worked a few times, happy days.

Came to get into it the next day, "engine disabled".
i now have to input the EKA code every time i want to disable and drive the car.

So two questions:
1. why do i have to put the EKA code in every time now, when i didnt before?
2. is there a way for me to disable this EKA Engine disabling safety feature through the BeCM?
so that i can unlock it with the key, start it and drive off, care free.

Thanks guys.

so a potential fix could be to turn both the immobiliser and thr eka off using diagnostics tool?

That is how I run both mine, it means that access and starting with the key blade is always possible if the FOB fails, although if locked with the FOB and unlocked with the blade, a lock unlock cycle with the blade may be needed. I did this after getting stuck in a multi story car park where RF from a radio transmitter aerial blocked the FOB and I didn't have the EKA code.
It is essential that both the EKA function and Immobiliser are turned off, this in effect sets mobilisation to automatic mode.
 
Given that it's a 1995 car, and might have an earlier BECM, it's probably worth trying Kieth's settings.

Disable both Immo & EKA using diagnostic, and then make sure you successfully write settings. Then lock & unlock the car using the FOB & see if it starts without errors ? After that try lock & unlock using key only & see if it starts.

*** Before you start, open the drivers window so you do not lock yourself out !!

great stuff, thanks chaps, will have a bash at this later this week.
ill come back and let you know how i get on.

also out of interest, could it be that they key/fob arent syncronised? or would that be doing something different?
apologies for the rookie questions.

If the Fob is not synchronised it will not work. With EKA and immobiliser turned off, the key blade will work as long as it fits the lock and the door lock micro switches are in working order.
 
hey guys, thought id come back and let you know how things were going.

i turned off the immobiliser and the EKA using diagnostics tool and this fixed my EKA lockout issue.

i changed my rf reciever to a genuine MK3 however, locks were still bouincing, so i changed my drivers door lock mechanism, and locks were still bouncing... AND when i pressed the tailgate button, it would ctivate the central locking... AHA!
i read on here that the tailgate button takes its earth from the drivers locking mechanism, so i took the door card back off.

mine being a early model it had the door lock mechanism with the seperate black earth wire on its own socket, so i wiggled that socket and black wire and the central locking made some noises and lo & behold.... it all works perfectly, locks stopped bouncing, tailgate locking unlocking operates as it should and all the central locking works using the key blade! Victory!

down side: no central locking on the key fob though, tried to sync the fob using the guide from RAVE and users manuel but no luck. so content to keep using the key manually for now until i figure that one out.

Thank you so much for your help and advice, no doubt youll hear off me again soon!

Do you know for sure your RF receiver is a good one? Clear the RF memory in the BECM, then try to sync using the key in the drivers door lock method. If that doesn't work recheck the RF memory, if it is still zero you may have a duff receiver or FOB. If not zero, it could be the driver door lock micro switches.

hmm good point, unsure how to test it myself. didnt realise you could clear the RF Memory, ill do that tonight.

Dont think its the fob as its reasonably new.
dont think its the microswitches as i changed the drivers side recently.

im hoping clearing the memory helps, if not then it could be the receiver itself. buggar.

will have a play later and let you know. thanks again for the help

New FOB? where from??
 
If that black wire isn't tied up properly it can foul on the window mechanism and break inside.

All 3 microswitches need to be working for the EKA input. Boot grounds through the centre one. There's a test sheet on here somewhere.
