How to remove ECU from tree in ISTA

[bavees]

Hi All,

I am looking at how to remove an ECU from the ISTA control unit tree so that the car no longer looks for it. 

I have a Canadian G30 but fitted some EU seats in it. My passenger seat no longer has a control unit but only the seat heating module. But the car is still looking for the ecu "SMBF". It shows in red in the ISTA unit tree and BDC registers an error because it cannot talk to it.

What I tried to do is:

TAL Calculation:
1 - Read SVT IST from car (the ECU is not listed there since its not connected)
2 - Calculate SVT SOLL (the ecu re-apears, in red)
3 - Edit SVT SOLL to delete that ECU and save

VCM:
1 - load the modified SVT SOLL in both SVT Current and SVT target
2 - write SVT target to VCM

But when I read the car with ISTA the ecu show up in red again.

The only thing that comes to mind is that because my typekey is still the Canadian/US one the car expects a passenger seat control unit. So wondering if I also need to write a modified FA with European typekey then re-do the SVT steps in VCM.

If anyone can comment I'd appreciate your input.

Thanks!


EDIT:

I forgot to mention I also tried to enable VCM update after TAL processing in options and run a TAL processing without checking any of the ECU's. 
Likewise also tried to load the SVT target in VCM then just code any ECU to force VCM update.

Neither of these make the ECU go away either.
