anyone have any information on using the Receiver and a paired remote for anything else? like tapping into the signals for other purposes? (in my case same purpose but on a 240)


I'm sure the volvo software has some good information but I can't access it at the moment... anyone familiar enough to pull out what I need? Or know off hand somehow?

I do have the wiring diagram but there isn't much, just pin numbers and colors.

ok

it's 4/19, right under the board



some good stuff here


plug like


5--
4--
3--
2--
1--



I guess i'll see what's up with it

Pretty sure you can do it.

For the 5 pins, there will be: 12V constant, Ground, ACC Power (to disable when the car is on and to enable programming), Unlock, Lock.

yea it's written out next to the connector on the board... but what's the +9 about?

its +/- and 3 going to the bigger unit RCQ RSS RDA -- is it even disabled when the car is on? I thought i've opened the trunk with it while sitting idling


i could really use some vadis information about the pins of that alarm system box "LOCK ALARM CONTROL" p/n 9472463 (denso)

ok now i see where you're going with that... but that's all done from the 2nd, bigger module based on what those 3 other pins are saying. I'm going to hook those guys up to the arduino and see what I'm working with....... once i figure out how to do that.

also still concerned at this "+9" .. do i really have to step it down from 12v?

Not sure, but I think there's just a single lead from the remote receiver
to the lock module that runs a digital signal for various operations.
You might have some fun dealing with that, but it'd probably be easier to
just pick up a cheap remote module from the aftermarket security world.

There are a ton of keyless modules out there you can do plenty with.
Stuff like this may be a lot easier:

Here's a little more -
Looks like you've got power,
ground and the other three
( these are for the pin #s on the lock module end...)

B16: Test signal for the receiver
A8: Signal, data from receiver, ID code
A9: Signal, signal strength from receiver

[bdimag]

awesome thank you! there wasn't more info on the signals and such? I cant remember if it goes that in depth.

still, i think this is something I can work with...

besides look at what i'd have to carry around as an alternative

[BEJinFBK]

This is just what I found on VADIS.
Let us know what you find out.

so that's a +B not +9

I hooked everything up last night: computer power supply for power and then hooked up the other 3 wires to an Arduino to monitor the signals....

The new battery i thought I had for the remote was wrong kind (2032 vs 2016), so this is on hold for a couple days.


what I'm really curious about is... what will I see on those wires? i guess the arduino can really only see the voltage between 0 and 5... could it be anything else? pwm?
