Hello
I did hsa and dds retrofit normally i never found hsa and dds supported a car upward 2011 as you know opel changed the abs socket after 2009 and i could not find abs ecu which supported hsa and dds on z13dtj. i bought a new old socket abs ecu. A friend help me about VIN for sps programming so only thing how to do converter between old abs ecu socket and new abs ecu socket. i made it within 1 day..so it worked very well no DTC.. but i got new problem central auto lock is not working regular but it s strange auto central lock is working sometimes or not so i can work it manually from switch button as you know auto lock function is activating after 10 km/h...even stop engine and restart it s not working...
what i have done maybe you can give me an idea about issue...
what i have done and what happening:
1) ABS ecu socket is not compatible with my car that s why i had to make a converter between old abs socket and new abs socket..
2) after replace old ecu with my converter tool , i didn t realize but it was working central lock and ignition 1 radio problem.. maybe i remember wrong
3) i changed the hazard switch because of dds button maybe i thought problems is hazard switch and i changed it with old one but no luck it s same problem it was not working..
4) i thought maybe problem is BCM i replaced the old one but auto door lock system did not work on old bcm but i noticed one thing when you remove battery or bcm it s working until to remove key but when you remove the key from ignition it s not working..
5) Last chance i will replaced abs ecu with old one i think problem is the new abs ecu..
6) i need to do sps programming to abs ecu for new software...
7) t&c is turning off when you stop the engine normally it was open until to remove key from ignition...
My question:
1) where does the central door locking system get the signal?
2) I did not check the cables but when i press the lock switch manually it works that s why i don t think it s about loom
i don t have any DTC it s clear but i have these problems What do you think about that ??

where does bcm get the speed signal? bcm is fine because i replaced old one it didn t work also on old bcm..yesterday it worked any time like new but when i removed the key from ignition it does not work anymore..i will replace old ecu if it s work i will change the can bus loom because can bus looms are 0,5-0,75 around maybe problem is?

Speed usually is calculated from abs/speed sensor in front wheel hub
So if it goes to abs ecu look for bad solder joint in your adapter.
But check wiring first where them cables goes

i will replace old one if it work very well i will understand problem is abs ecu loom or incompatible with my car so i will do sps if it does not work i will drive like that..
