Will your tool monitor the wheel speed sensors while driving? If not then your tool can only get engine codes. Which is why you can not get the codes from the ABS module.
Have you done any diag steps for the codes you have?
The all caps message is making it to hard for me to focus on all you have written. I will opt out and let another see if they can assist.

I am confused. Why are you concerned with injector function? I say we focus on P0420 and P0430 and see what happens from here. Can you monitor B1S1 O2 sensor data? and B2 S2 sensor data? please graph if possible and send a idling after engine warm screenshot.
Sorry all caps will not work for me. I will opt out
