Hey there guys!

I wanted to retrofit a Coming Home Module for my Astra J (A16XER).
The aftermarket Module needs a „door open“ signal to trigger the relay inside of it. I looked up in Autodata and searched the Internet but I cant find any useful information unfortunately. All I know is, the Body Control Module (BCM) should process the Signals but there are many cables to measure them all for my needed voltage signal.
Does somebody know or has a Wiring diagram/Pin assingment picture or something like that?
In the best case it should have a (short pulse) 12v Signal and no Canbus Data signal.

Thank you guys in advance!

Best regards from Austria,
Eric

Hey there Rusty again, today I had a look at your pdf files and I thought it would be K6/Pin 21. But this Pin isnt even in the named plug. I measured the whole plug for the signal and came to a result it would be K6/Pin 4, I provisonally tried the module with Pin 4 and it worked I guess but after connecting and triying it out, the remote unlock/lock doesnt work anymore if the module is connected to this pin. Only after disconnecting the module the unlock/lock action worked again. It seems like, if you put any load (a relay) to the related pin, it doesnt work.

Maybe did I miss any pins relating my unlock signal? :(

Have you tried K6 pin1 or 2 Or K2 pin15

**EricMod** · 11:th-Oct-2018, 08:56:00

Tried them all too yesterday, unfortunately nothing usefull :/

Isn‘t behind the Speedometer dash, the key transmitter module itself?

Yes it is.

Could be wrong, but I think the OP wants something different to this.

Pretty sure what you're suggesting is standard fitment on most Vauxhalls now, so the OP would already be able to do this.
