milk in my becm

someone smarter may wander along, but: The BeCM drives the rear door lock actuators directly. Does the dash tell you when the Rear Left is open? If no, then it may be worth pulling the door trim and checking the earth connection for the actuator, and then while you're there work out if the pink and orange wires and the CDL motor, are working.

If passenger rear window is also not working then maybe something is going on with the wiring in the door jam (or it's all been disconnected). A nanocom could also test the window via the BeCM... does the window not work from the door AND the centre console ? In which case wiring issue, dead motor or drive gear stripped, probably...
For rear right- sounds more physical ie linkage broken- door card off, for starters...

Hi
The problems are
1 Drivers rear door won't unlock, from outside or inside, or work with my key or fob
2 Passenger side rear door opens and can be locked manually with door button, but doesn't work with key or fob
3 Passenger side window will not close
4 The front doors work on the key and with my fob.

If front doors work on fob and key then sounds like central locking is working in that the microswitches are registering a change and sending the message. I'd try Marty's lock tests on the rear passenger door or take the actuator out and test the motor but the lightest of touches with 9V battery or power supply.

The driver's rear door does sound superlocked. Have you got a Nanocom or similar to try sending an unlock pulse?

Passenger window. Can you hear it click or grind or just dead? Could be the switchpack or given what has happened it might be the relay in the BECM. I'm not sure which it is but people have replaced them. Process of elimination if the others work, I guess.
 
Hi
Just been out to the this morning, car started ok, tired the passenger front window...….went up :):).....so I'm going to leave that for now.
Both my rear windows are working from the console and the door switches....
If I leave my passenger side door open a message does come on my dashboard indicating its open.

Thanks everyone for your help!!!

Going to remove rear door card and check the actuator.....if the signal / pulse comes from the BECM to unlock the doors what volts should I get at the wires?

12V brief pulse from memory.
 
Hi
Got the rear door card off, nothing standing out, unplugged the socket from the actuator. Does anyone have a link for pdf Rave Manual, hoping it will give instruction on how to remove the actuator from a superlocked door. Whats the wires for ( eg Black = Earth) and what readings should I be getting from the plug outlet.....do I get a pulse reading as I press the key fob through the BECM.
five wires
1 orange
2 black
3 orange / white
4 purple / white
5 pink
 
Hi
Cheers for the tag!
Wouldn't know the EKA code, and could never get to work.
Just thought I could put 12 volts on the right terminals in the actuator socket to just turn the cam into the lock position then maybe use my key fob or opening using the door button and internal door lever.

Get it from the main dealers,take the reg doc and photo ID.enter it as per users manual or if you don't have one search eka code,@DanClarke did a good write up.
 
Hi
Its been that long ago but bought my car 10 years ago with it having a Engine Disabled Fault, had a chap who when he came over from Ireland for his MOT, he would take booking to have your Becm 'immobiliser disabled' and I'm sure he disabled the EKA code for me, it was ten years ago and never had a problem. :)

orange wire and pink wire are going to the CDL motor. I think a pulse will do it, or try that first. I'd try a 9v battery for power too don't go for orange and pink - that's the super lock motor. Not sure you should have orange/ white ... check out section S3 of the Electronic Troubleshooting manual (in RAVE) for your year of car

Will those who claim EKA and immobiliser CANNOT be disabled with fault message on dash needing EKA code to remove take note of the above. Maybe learning how to use your equipment would be a good idea. :D:D:D

It can't be done with nanocom in the car.
I have a video to prove it.
Other equipment may well be able to do it with the becm on the bench but I can't comment on that.

I know exactly how to use it. Both myself and @martyuk have told you it can't be done yet you persist in saying it can.
Do you really want me to upload the video and make you look silly?

It can be done i have done it several times. If you don't know what you are doing that is not my problem.
