Not sure if my '13 LC doesn't has AFS, but hopefully not... nothing but problems with it on my LS.
Mine did - I have a 2018 - and im trying to figure out why they've stopped doing it. It was an always on automatic sequence when starting the truck. I have a part number for the Headlight Leveling ECU - 89960-60052. but when I look the part up, all I get is an engine block schematic.... Trying to figure this out - whey they've stopped on start up.
yep - thats what the service writer tells me too. BUT, ive watched it for 4 years before they stopped so I know I have it....

That part number comes up as "Computer assembly, headlight leveling : KAZAKHSTAN SPEC" in the parts diagrams. Not sure why I think that's so funny..
Edit: sorry, I had been doing digging on LHD headlights and had it set to RoW. That part does come up for US 08/2017+ URJ200s without any kazakhstan notes.

Thanks - im trying to figure out how to get to it. Parts guy made it seem like a footwell panel to the right of where the feet are. This diagram - in the glove box?!? I cant tell. Sorry....

Foot panel will need to come off. Probably also the panel under the dash to look upward.
Possible that you need to remove the glove box which means removing the knee airbag, and that requires pulling the knee pad on the side of the console, and the silver trim. All of which is actually pretty easy.. just go slow and careful.
Sounds like a lot to take apart with no schematics. Looks like it’ll stay broken.
Had a service appointment at local dealer and asked them to see if they could find any faults with the auto leveling headlights not self checking on start up anymore. On pick up, I was told that there were no fault codes and the lights are working fine and that they "move on start up" when going through a test if there is something wrong, to try and fix the problem. So, no movement on mine means that all is well , they tell me.
So , this begs the question, if they dont move unless there is a problem, this means they must have come from the factory moving to try to self -fix a problem ?!? For 4 years until they stopped!
Can anyone tell me, once and for all, seeing as no dealer seems to know, or Toyota NA, what were the headlight doing when they moved on start up, are they suppose to and if they are suppose to, is there a way to tell what the issue is that causing them not to anymore and how can I fix them?

Does that light come on at startup?

This shows there is definitely a separate ECU for the leveling control “HL AutoLeveling”
If it was me, I’d want to see if techstream could talk to that ECU. I know in LXs with AFS, pulling the fuse to the AFS ECU basically deletes the feature and removes any warning lights and DTCs, and most likely leaves that ECU grayed out in Techstream. In that same post he screen spotted the data list as well for that ECU, so you can see all the sensors the ECU uses to make decisions. The vehicle in that thread is a 2018 as well.

No. Never has.
I went out and bought odb fusion. It doesn’t pick up any error codes. BUT, after I was unsure if I was testing correctly, I called them and was told it is not capable of testing for ecu for headlight leveling.
if the ECU doesn’t have power, there will never be a code. There also won’t be a light on the dash at startup. That’s what the notes on that table of dash notifications says (if you read between the lines). The fact that you don’t have the light at startup is a pretty good indicator. Assuming the user manual is right. I don’t have a 2018 LC so I don’t know for sure.
Techstream would be cooler, but I’d double check OBD Fusiion. My version talks to the AFS ECU. If you do a scan and can’t see any of those PIDs, then that would be another check towards the ECU not having power. You have to have the Toyota/Lexus pack installed to see these. The LC HL Autoleveling ECU will have less PIDs, but there should be something there.
You have to do a scan on the "enhanced" networks to get it to see them. But if you did that scan, and it didn't show up, then we are back to most likely that your ECU has stopped functioning.
Ok. Pretty sure I did that. Tied up for the next hour or so and will re scan to double check and post back here. Id
Like to get this fixed once and for all - appreciate the help!!
Pretty sure I asked this in the other thread. But, I checked the fuse and if I checked the right one, no issues. But I’m guessing if it was blown, other things would
Not work also, right?
Sorry to trouble you. But is the anyway you could just list the buttons / choices to select on the obdfusion I should select to make sure I’m doing it (scanning) right?
What to do after I’m connected Bluetooth to vpeek scanner…..
Theses steps are for OBD Fusion on Iphone
Step 1: Make sure you are disconnected from the scanner. (Do steps 2-4 when away from vehicle if you like)
Step 2: Click the little vehicle icon to get to the "Vehicle Editor" (Bottom left corner) (Alternatively, go to "Settings - > Vehicle Editor"
Step 3: Go to "Enhanced Network" and select "Network E" (this is what it is on the LX, i assume the same for LC. Look for the network that has HL Autolevel ECU listed.
Step 4: Click "Ok". It should now say "Network E" under Enhanced Network
Step 5: Click "Back" to go to the main screen and then click "Connect"
Step 6: Accept any warning offered. If you have never done this before it will most likely prompt you to scan all ECUs for new PIDs. Also, if you've never done this, then you've never actually scanned for your HL Autolevel ECU. Let the scan complete (might take 10-15 min)
Step 7: Verification: Now you can go back to the Vehicle Editor and click the "View Networks" button under "Enhanced Networks" section. Scroll down to the HL Autolevel ECU and see how many PIDs OBD Fusion found.
Mine shows 13 for the AFS ECU. Based on the screen shot from the other user, if yours if functioning correctly it will say 9 PIDs, and if not functioning it will say 0.
I suspect that the HL Autolevel ECU probably has its own fuse, so i would suspect it's entirely possible that the ECU could have a blown fuse. But also, possible that the ECU has failed.
