I am having some codes on my 02 Nissan Xterra 3.3L 4x4 Automatic with 200,000 miles, which I have been discussing in other threads. Today I went around testing and replacing fuses.
I noticed that mini fuse 7 (ECU, Daytime Light) isn't getting any power. The fuse it fine.
I understand what the fuse does but what could be a cause and what could it be effecting?

The vehicle runs and drives fine but I do have codes. I have been inspecting wires and fuses and grounds to see if that's why I am throwing so many ABS codes.

P1706-part ordered
P0327-relocated, code came back up after a few days

ABS
C1113
C1108-part ordered

C1104-part ordered

That fuse (the 7.5) is only hot when the key is in Start, so likely not an issue. The 10a below it (#8) does feed the ABS and should be hot during On/Start. Don't forget about fuseable links D and C under the hood

For the knock code, as long as you're not supercharged, it's not an issue.

So, that number 7 isn't hot when in the on position or when the car has started. Number 8 is hot. Is the fuse able links d and c in the fuse box under the hood? I don't see any fuses connected to the battery cables. Hopefully that is not a dumb question.

Yep, fuse box under the hood

We're getting to the point where you might need to start looking for a new to you pump. Don't forget to check at the connector as well for the voltages to rule out a damaged wire.

I think I am in over my head with the ABS. It doesn't help that I don't know the history of the car and why there are some of these fuse mods done to the car. I have a mechanic that allows me to purchase the parts and take them to him. He can use what he needs and I can return what he doesn't. I'm going to take him speed sensors, pump, and g sensor and see what he can do.IMG_9198 2.JPG

I don't understand the jumper wire in the photo above going to the low tire pressure warning system and I don't understand the jumper wires in the relay in the attached photo?
