My tcm got transfluid in it. Blew the tcm fuse under dash. Put a used tcm and valve body in. And my 4x4 light is still on. Picturegram is blank. Has a p1819 code. But fuses seem good. The relays click. This happend the exact same time the tcm went out. I have a new valve body comming because nissan says they cannot reprogram a used tcm. Wondering if the tcm has anything to do with the p1819 code not being programmed. Or could the tcm failure caused something else to blow other than a fuse. What pin on the transfer case harness can i check for power.
P1819 Power supply circuit for transfer control unit.
This is electrical even if you wanted to reprogram the unit , it not foing to work when there is a DTC stored in it.
The 40 amp fusable link has to be checked, the 10 amp fuse which is fuse 21. and fuse 57 and 58
