I've ordered an EWD, but I am currently troubleshooting trying to find why the fuse keeps blowing. 1 day while driving all the gauges we're inoperable which led me to stall out then I learned the alternator was not charging as it's on the same circuit as this fuse. I replace the alternator had battery checked investigated around the fusible link almost too many things to list problem still exist. The fuse blows as soon as the key hits the on position. I've done things like check then clean grounds have a Power Probe and I ect3000 trying to trace the problem, I've looked all over for signs of melted wires broken connections xcetera. if anyone has any parts of the electrical wiring diagram showing 2001 Land cruiser 15 amp Gauge fuse circuit that can help locate this issue sooner rather than later would be greatly appreciate it

This happens to me when I move the transfer lever to L4, Haven't found the solution yet but I'm guessing it involves my L4 switch and the wiring harness. You can check the Service manual available on MUD, it's under the "Body Electrical > Combination Meter" Section

Using a light bulb connected to 15a gauge fuse terminals, identified two harnesses behind glovebox that when unplugged would make the bulb go out. Oddly enough another nearby harness showed signs of getting overheated but at this time seems to be okay otherwise. I also discovered some apparent amateur rewiring at the antenna relay I was not aware of but that doesn't seem related at this time and apparently has been that way for 10+ years, prior to me owning the vehicle. Using torque pro I am getting P0500 VSS code, which makes sense because I remember disengaging the cruise control right before gauge fuse blew and all gauges went out. I am going to investigate the VSS problem shortly, hopefully this gets me to root cause of this issue. I will keep this updated for others that may experience same issue. Photos of two harness signaling a short and the one harness (two pics) that shows signs of overheating at some point. One question for the VSS code should I be checking the connections at diff and transmission or the four sensors located at each wheel or all of above?
I am getting the P0500A code. My Speedo, Tach, and ODO are dead. I replaced the VSS and it did not do anything. Please elaborate on your findings when you get a chance. Mine is a '99

My issue began with losing all gauges due to 15amp gauge fuse blowing. I'm guessing yours are just inoperable but not due to a fuse. I think I've actually narrowed mine down to being the VSS sensor in the center diff, and (hopefully) not the wiring, as I cant locate a wiring issue and with the original VSS removed from the plug, my fuse isnt blowing any longer. I should receive a replacement VSS tomorrow and hopefully that takes care of my issue as it seems the short I had was in the sensor not in any wiring (hopefully). I have the 2001 LC wiring diagram if you re need of any diagrams let me know, may not be exact for your 99 but could help possibly.

Issue solved!!!!! Replacing the VSS was the remedy, just would have been easier if I wouldn't have disassembled half the dash to trace the issue down to the center diff.........

I sent you a PM. Question on this, with the gauge cluster dead, did you notice your alternator not putting out correct voltage? I winched a lady out of the mud on Monday. Noticed my gauges died in the process. Replaced the fuse, it was fine for a day. Noticed the next day it was blown again. I also noticed that my alternator was only putting out 11.5 volts and it always puts out 13.5+
I just replaced the fuse again and read the code. I have the P0500 VSS A Circuit code. This sounds very similar to your issue

15A gauge fuse referred to was located DS kick panel.
Its prob not blown because you'd lose the entire cluster if it was, and alternator would not charge the battery, at least on a 01 LC

According to my amazon purchase history this is what I tried first and its still working today
Amazon product ASIN B079R16ZZJ
Thanks! My code reader says speed sensor A. That’s this one?
