Remote lazy locking / venting.

[phenonix]

as in not splicing into the BCU but somehow into each door control?

i have looked into the sunroof, it has a separate BCU? in the roof.
I already put an extra loom there having done the footwell and ambient mod so these wires are waiting the be connected the the roof BCU, what were you thinking of how to get around the remove key timing?

Sorry mate, you've lost me there

You are right in your assumption.

If you think about it, remotely starting the engine, whilst I wouldn't do it, (certainly not in a manual car) would be remarkably easy.

Good, good. I have an auto now so if left it in reverse i could get it to back out of works carpark for me. Home James.

I can follow that.

What I can see compounding the issue, is the fact that that circuit is also disabled a short time after the ign key is removed.


I think the sunroof has the same disabling function, i believe it is a safety thing built in.

If you were directly wiring it there shouldn't be a problem. If necessary, you could isolate the sunroof ecu with the same relay that you'd use to provide the drive voltage. That would be the same requirement as for the powerfolds (IF I can't do the required surgery within the OEM switch pack).

Ten channel Receiver is now fitted and working

Just the four channels enabled so far (lazy locking, lazy venting, boot release and FBH control).

Remote powerfold opening and closing will be added when I've sorted out how I'm going to do it.

I'd still like to be able to sound the BBUS at will from the remote as well but can't see (yet) how to do it...and more importantly, how to switch it off

[Raistlin]

Now with added remote control powerfolds

Well... it keeps me off the streets.

The story continues

This is a simple drawing of the circuit I used for remote operated powerfolds:-



As far as I can tell, the sunroof control switch has much the same function so if you substitute the sunroof ECU output for the OEM switchpack in this diagram and assume only one motor, this circuit will work.

Both lines are held at earth by the switch regardless of whether the delay is in operation or not under normal operation. (The doted lines indicate the original wiring).

Clearly, all you are doing is open-circuiting one of the lines from the control of the ECU and connecting it to 12 volts to drive the sunroof one way using (as per the diagram) relay 5 with relay 6 driving it the other way. The relays are, of course, channel relays in the remote control receiver module.

This operates directly upon the sunroof motor, of course, thereby bypassing the delay function which is clearly built into the ECU.

However, when the remote isn't used and the relay contacts are in their N/C position, the function of the original sunroof switch is unimpeded.

I know it is a desperately simple little circuit but it works

Hope this helps


BTW. IF I can get hold of a powerfold OEM switch I'm going to have another look at simulating the operation of the switch itself by momentarily contacting it to earth. If this works then it will only require one remote channel to drive the mirrors in both directions. I didn't fancy experimenting with my only powerfold switch though

Thanks Paul
I'll give it a try
