Really dont know, but maybe, this module is just a relay, when it received 6V close a circuit and send 12V to the cam (in order to turn it on), also to "convert" the signal video (from cam) to their own type of cable (instead of simple RCA)... all this is my guess.
This is what I understand about this...
When you shift to Reverse:
1) HU in PIN 30 (in connector M45) received 12V
2) HU in PIN 14 (same connector) send 6.2V
3) Module (Part #284A1-JA000) received 6.2V and (my guess) send 12V (or whatever Volts need the rear cam)
4) Rear cam (Part #28442-JA000) received 12V (or whatever need) and turn it on, then send video throu the module
5) HU in PIN 15 & 16 received video and it shows in HU Display
If this is correct... then just simple connect cable from a universal RCA rear cam in PIN 15 & 16 and supply 12V from reverse tail lights...
I cant do anything else, need first a universal RCA rear cam in order to test, but if anyone knows... please tell me

Do you have any other documentation??
