Air bag DTC's

I'm hoping someone can help with some info on the cause of some airbag DTC's

Background. I bought a damaged JDM 2015 Leaf Model X (the middle spec) that had driven into a truck trailer on left hand side just above the reinforcer. So pretty superficial damage. I had a bunch of SRS codes, and have been trying to eliminate them.

Initial DTC's were B1421-00, B0001-13, B1431-13, B1430-13, B1433-13, B0010-13, B142A-16

I have used 2.2 ohm resistors to simulate the SRS components that I know have activated in the collision. These are LH front air bag, LH seatbelt pre-tensioner, RH front air bag, RH seatbelt pre-tensioner, driver lap seatbelt pre-tensioner

Remaining codes are B1421-00 and B142A-16

I am unable to reset either of these codes

Can anyone help with the cause of the 2 remaining DTC's?

Thanks in advance for any help

Years back, on a different Nissan car, to reset the air bag codes you had to put the car in Aux, an push the diver door open switch like 7 times in rapid succession. The switch on the frame that senses door open. I am not kiding, it worked for me on a 1999 Nissan Frontier.
