Default Battery Relocation Compact BST Coding

Hello Peeps,

I'm trying to understand why I'm getting this error after my battery relocation.

the car originally is a 316i compact, which did NOT have a BATTERY SAFETY TERMINAL.

It now got a m54b30 motor so i decided to relocated the battery in the truck for better weight distribution.
I have now moved it to the back with a complete battery harness from a 330ci.

I also wired in pin 49 and 50 for the BST disconnect. Upon powering the car, i got this code without any coding i got this error code in the airbag module.

I mean i didn't even connect the 2 Pins for the BST and it threw this code, how did it determine this without any coding. It still got a +12 to the airbag module.

"0B battery Positive terminal isolation 1." (will post inpa detailed code later)

So I added [*S832A* BATTERY IN LUGGAGE COMPARTMENT] to my FA list and coded the MSR4.
The code is still there. Is there anything else i should add?

or anything I'm doing wrong?

Lastly I also found this document in TIS,

[Only for registered users... ]

Safety battery terminal (battery terminal disconnection)

To reduce the risk of fire in the event of a head-on collision, the battery terminal disconnection ignition circuit is also activated.

A separate dedicated gas generator (safety battery terminal) disconnects the high current line (terminal 30) from the battery to the starter motor/alternator.

E46 4-cylinder models Left hand drive vehicle

Since no increased risk of fire can be observed when the battery is installed in the engine compartment, the safety battery terminal is dispensed with as of March 2002 (03/2002) for all E46 left hand drive vehicle models with 4-cylinder engines.
Will changing the Vehicle type help from AT51 to a 6cylinder help? (OT: is there replacement for ZEKO since it only runs on 32bit system?)
