Hi,
Why you are writing twice Output_Low, one of them should have been Output_high ? No need to set TRIS?

Config word
3 1 c 4 normal Means pin RA3 can be used as input
3 1 e 4 used as reset can be used ONLY as RESET
I tried to figure out your C and I undertood (maybe WRONGLY) that you use RA3 as an IO pin,in this case Config word should be 3 1 C 4 or 11 0001 1100 0100 B
