Facelift & Pre-facelift central locking ecu's...

[PaulW]

Just a quick question...

Both pre-facelift (mini) and facelift, they have a seperate ecu to control the central locking don't they??

Wondering what differences lie between the two, ie, are they inter-changeable so to get the 3-button fobs with boot release??  And also, any major differences with the loom for them??

Fitted a facelift boot to my elite earlier, everything works, even the boot release, but it pops the boot when the central locking is unlocked, so just wondering if its possible to retro-fit the new ecu to get seperate popping control, or if i'm best just hashing into the wiring and sorting something else out??

Cheers

Can't answer your question, as I don't know. Sorry.  But be aware that the central locking is part of the alarm ECU if you have factory fitted alarm, and not a seperate ECU.  If no factory fitted alarm, it has its own ECU.

The whole thing is factory, alarm etc...  Have the imob. codes to boot aswell on the little card.

I'll try hunt down some sort of wiring schematics if I can find anything...

Wiring diags for 2002/2003 Omegas are on the later versions of TIS if you have access to that.

Have an old copy somewhere on CD, aswell as the online section via the TC site (if i subscribe to it that is...)

Wiring diags won't be on earlier CD ones, only the DVD ones from last couple of years

Not got the dvd one then

I've no electronic one, but its in Book of Lies...

Will steal my brothers

But, if I was to experiment, and get a new ECU from a latter car...  How would coding keys be done??

The multiplug where they connect to the loom looks exactly the same, so would I just need the new Imob code for the keys, and retain the original chip in the key??

I'm guessing (hoping) Tech2 will still talk to it...

Looking at getting this just to experiment with you see...

if you use the fobs that came from new car, that should work i would have though  :-/

Immobiliser is seperate, and should be able to use old one.

[PaulW]

Cool I'll see what I can find soon enough at the scrappers...  Or see if anyone is breaking a facelift, and get the bits I need!

[PaulW]

Just waiting on the ECU, fob and carpass card to arrive, so wondering if anyone might be able to shed any more light at all??

Yup

Appears to be the same connector and much the same wiring (made some notes at home jsut after the lakes meet).

The ultrasonic interface is different and the wiring to the boot lock solenoid is pretty much the same.

One extra wire for the switch and a few feed changes to.
