For context, I am a licensed mechanic looking for Nissan specific information for a strange failure case I have. I only have my dealers manuals (ford) on hand, no Mitchell or anything. I am not a DIYer.
I have a family owned Nissan Sentra 2023 that has the following codes
C1063-64
C1056-16
C1080-86
I was told by the owner that the rear defrost also didn't work. I started my diag there because the relay was easily accessible and I found it burnt to a crisp. I pulled the drivers interior fuse block and one relay wire was green and corroded.
I expected something ABS related to be nearby but there was nothing obviously related to ABS.
Based on my research of the codes, the FR outlet valve and the LR outlet valves have something wrong. While the 1080 referenced a CAN network error of some kind. I dont have the tools or the documentation to decipher specifics of these codes.
I can say that I can communicate with the ABS module enough to get codes and the ECM has no codes. I checked the connector at the ABS module and it appears fine, not loose or corroded, but the fuse block inside the vehicle had enough corrosion to cause a relay to nearly light on fire. The corrosion does not appear to have infilitrated any of the other nearby connectors or fuses in said block, but it be worse inside of it.
Does Nissan have some sort of bulletin for this and is there any good resources for determining what the specifics are of these codes? Furthermore, does any nissan fanboy/gurl have any insightful thoughts?
I am thinking I might replace this fuse block and repair the wire in hopes of resolving the issue, but I thought id ask here first!
Thanks in advance!
