becm won't go to sleep

hi,
because all the trouble i had with flat batteries and stuff, i was looking on the web and found this site. Does anyone worked with them?

Sending your Becm for Test-P38 Range Rover Electrical Common faults and Fixes

allready thanks

kristof

befor i sent it anywhere i would pm irishrover. he is the man to sort you out.

have you tried searching landyzone for help?

Disconnect the Remote locking aerial behind the back seat and see if that will do the trick.

but the problem is, i can't close the car with the remote. Only with the key. And than the turn lights will not blink. When i disconnect the battery for the night. The next morning when i connected te battery again, every thing will work propperly. Event the remote works. Turn signals blink en the becm will go to sleep in seconds.
BUT, and now it come:
when i put the key in to start, without starting. When i than get out of the car and try to close the car with the remote, is't game over. Not the remote not the becm will go to sleep not will blinke the turn signals.
It's like there is a problem with the code in de remote and becm. One of the 2 is forgetting the wright code. Think i start with buying a new remote and see what it will bring.

or does someone has an better idee?

already thanks

have you tried putting key in door pressing lock and turning to lock the same for unlock? what year is your car?

I'd go for one of those Synchmates before getting a new fob. At least if it doesn't solve the problem you'll be able to sell it on.

tried that. pressing the key but i read that it not working on a '98 car. Only for the older cars it works.

works on mine. 2000 4.0. is it starting ok?

starting is no prob

i just got new fob and thats how i synced it to the car, how is it now with rf off?

Hi what is this?

BECM not going to sleep (or repeatedly waking) and draining the battery sounds like an RF issue. If you unplug the RF unit behind the drivers-side (RHD) rear parcel shelf the RF will still work but only when you put the key near the window.

If the remote won't lock the doors but the car starts fine etc then it sounds like the lock motors might have burnt out - common if getting RF interference.

Question: if you unlock or the doors when inside, do all the other doors lock OK (or unlock)? Same passenger and driver's side?
