its worse than that, its dead jim !!! 1996 p38 imobilised.

Good Morning, I recently went through the exact same thing. I have a 95 se that i thought was immobilized or the ecu was not communicating with the becm. After continuous research and 10 days of trying things...
I finnally got her started (thanks to datatek & mozz who posted on a past thread)

So, to give a lil back story......
I did everything you did..... with no luck at all
I changed my fob battery.. no luck or light on the fob
I changed the truck battery.. no luck
I entered the generic eka (1515).. no luck
I tried the positionII and battery disconect.. no luck

I have a 99 4.6 as well that has had the the alarm and central locking removed (how i dont know, purchased it that way); i took the key pad and battery back off of the 99 and put them on the 95 key. Now my my (the 95) remote lights up with no problem & key batt low message is gone. (the keypad was worn and the batt connector was a little loose; now firm and perfect)

I go to the truck resync the key and try to start.... NO LUCK!!
I removed my battery and put it in the 99.. the 99 started right up; so i knew the battery was fine...
Replaced the battery, set the windows & LOCKED THE DOORS tried to start.
I got the 'engine disabled press remote mess'.. pressed remote tried to start. no luck. Took key out of ignition and tried again.. This time i recieved the alarm triggered, ignition tampered message. That message was new, and remember reading something about the ignition

I pulled out my laptop and remembered reading a comment by datatek and mozz.
I go to a past thread and read to go under hood and check the 30 amp fuse in slot 2.. and to switch the relay from number 16

YUP YOU KNOW IT.. Fuse was good. Relay was brown at 2 points. I switched it with the air susupension relay since i converted her to coil, turned the key and VRRRRRM..
switched it back to make sure.. nothing just a click in the door and under passanger seat.
Switched them back... PERFECT..
I got in the truck.. LOCKED THE DOORS WITH KEY FOB, attempted to start. got message, hit button, turned key, VRRRRRM. She started right up.

Ive read that the relays can immulate becm conditions. Ive oredered a new relay kit from AB..

LONG STORY SHORT... HAVE YOU CHECKED YOUR RELAYS?
Thanks to datatek and Mozz; my rangie is rovering...

Gone quiet. Maybe he's hit the beers already? I think if I don't hear anything int he next hour I'll do the same!

Thanks for your valiant efforts tonight Grrrrrr.
looking on the bright side im saving a fortune in fuel

rangeroverfamily . fuse box and relays are all fine. fuse box was replaced about 4 years ago. when i inspected it the fuse box was still looking like new.

nanocom reports communication with the ems has not happened in the expected time frame

well had another look at the range rover today with the nanocom. tried clearing the rf memory , that made no difference.
disable alarm, it says nanocom has instructed the becm to change the alarm status,
but its still immobilised.
entered eka code through nanocom. still no good
security relearn, not happening as nanocom says communication with the security ecm has not happened within the expected time.
also when i input the various options , ie sunroof fitted, trip computer fitted, rhd, english, auto, and so on, then write settings, nanocom says settings written. but when i go back into the settings they are changed again.
am i doing something wrong or is the becm kyboshed ??? am i barking up the wrong tree thinking its the becm ??

I suppose the battery voltage is good at the BECM?

was worth checking thanks datateck. voltage is 12.4 at the battery, the same at the fuses in the under bonnet fuse box, and 12.3 at the thick brown connections to the becm.
i have to get this sorted soon, the mot is out on jan 12. :frusty:
and also at the moment i am running around in a suzuki wagon r (in turquoise blue)

Any luck yet? Were Mozz or RickThePick able to shine any light?

I still don't like the way the BECM kept forgetting settings.

no change yet jules. spoken to mozz on the phone and went through all his procedures but still nothing. cant understand why the nanocom wont re sync the becm , it will probably end up with bill over at autoland in houghton regis if i cant sort it my self. im a bit loathe to rip out the becm and ecm to send to rick if its only a re sync thats required. i think i was kind of hoping some one would say "i ve had this problem loads of times and it is definately an indicator that blah blah blah is wrong, do this and voilla sorted"

got to get a move on though, mot is out jan 12th.

You need to get the becm to me. Nothing you do is going to get you going.

well thats it then, BECM is winging its merry way to rick the pick for a thourough thrashing with a big stick.:deadhorse:

some say he rips their insides out :behindsofa:
i just want it working again :Cry:

well rick has given it the thrashing of its life, and it has promised to work now. so in the morning it will be time to refit the becm and see what happens. hope the weather holds out

its update time.
the becm is now back in place, however the engine really does not want to run properly.
it was fine before the shenanigans with the becm. im hoping its just the adaptive values that need time to reset. how long do they take to reset themselves ? i went for a drive of 14miles and it seemed to get better but after stopping the engine for 30 mins or so its as rough as before and doesnt want to rev freely, foot hard down and it just coughs and splutters not getting to full revs, this is both on petrol and lpg so dont think its fuel.
there is always something with a range rover

take maf off give good clean on thin metal strips ,i used nail polish remover witha couple of ear cotton buds then air dried it before refitting and it worked a treat that was 18 mths ago cheers mozz

cheers mozz will give it a go

It is running! Result!

Nice motor. Hope you get the niggles sorted out.
