While in the process of troubleshooting an AHC system problem I came across this abnormality on my 2013 LX. Pictured below is my actual fuse box. The red circle indicates where the fuse box cover says an AHC relay should be:
Here is a picture I found on Ebay of a fuse box pulled from a wrecked 2013 LX570. Other pics I could find show the same configuration
I bought the vehicle from a dealer back in 2020 with 109K miles and have now been trying to troubleshoot an issue with my AHC detailed in this thread: 2013 LX 570 AHC issue - Code C1763 and Possible Missing AHC Relay? - https://forum.ih8mud.com/threads/2013-lx-570-ahc-issue-code-c1763-and-possible-missing-ahc-relay.1380151/
Ever since a sensor lift 50K miles ago (truck has 175K now) the AHC would work but the pump was running constantly trying to raise the truck. Pump finally quit a couple of weeks ago and I've been troubleshooting since (see thread). So while the AHC "worked" in this configuration I cant help but think my strange fuse box may have something to do with the issues I'm having.
If you guys were in my shoes would you change out the fuse box for one with a relay socket for an AHC relay? Could the existing fuse box be modified? The AHC fuse under the glove box is intact. Pretty please with sugar on top help me figure this out!
