Abs and Pas are on different branches of the can network and if you plug either unit it it drags down the entire net work. I can't see how both units have crashed at the same time.
I also think that very early on I had both units unplugged with no change to the ecu comes.
It was the latter stages when I noticed the CAN trace at 6 and 14 had improved and allows vehicle to start.
I believe the CAN to be not strong enough to support more than 2 units and add anything else it crashes
Will go out today and confirm with ecu unplugged what the coms to PAS is like.
Thanks for input
