Hello I am reaching out in the thread in hope to find someone that can help me figure out the issue with my Headlights.
I decided to wrap my car and I ended up disconnecting and front Triple beams and Led check marks to remove the bumper and after re installing everything back now my headlights and check lights seem to be out of sync and turning on at uneven times, even my light switch seems to not communicate with my headlights as they stay on even when I turn the light switch completely off.

I called a service rep for Lexus and recommend to bringing it in for a headlight “Re Initialize” and they said would cost 275!
I could imagine it would be like a mechanic tech trick like disconnecting the battery or turning on the key and moving the switch. Or something

I look forward hearing from someone with helpful insight!

 

I have an initialization thread and a video on YouTube, but here's the section of the manual. https://www.dropbox.com/s/zmyg1s3kol...ATION.pdf?dl=0

The dealership shouldn't charge you any more than an hour to do that.

You have 2 steps: 1) sync vehicle info, then 2) sub-assembly initialization.

The sub-assembly initialization is what I covered in my thread and YouTube video.

Easy mode for step 1 (sync hardware) is: turn on Ignition (don't start engine), turn headlights from on to off 8 times within 20 seconds, if done right, you'll hear a ding and headlight icon will blink, turn ignition off. Then follow steps for step 2 (initialize LH system).

 

Did you end up getting it to work? I have the same problem. My high beams don’t work also. Did yours work?

 

Hello, will this work for adjusting the triple beam LED headlight position? I have a UK spec, RHD, 2015 RCF, the lights shine to the left. I've brought the car to Germany and need the lights to shine to the right. Lexus says they only know about replacing the light assembly which is over €2000, for one!
Does anyone have advise on how to adjust the lights? The "L" or "R" does not do what it needs to do.

 

This is not an adjustment, it's a reset of the self leveling system that should be done after changing the ride height of the vehicle or changing parts such as the headlights or rear suspension.

I'd recommend performing this reset, then moving along to final manual adjustments. On the cover along the front in the engine bay you'll a label for 3LED and for 2LED. You'd use a really long philips #2 screwdriver to adjust the up and down. For the triple beam, you'll use the adjustment labeled 3LED. I'm not sure if the triple beam actually has left/right adjustments. They just use the same plastic covers for both headlight options.

 

OK, that makes sense, as I did not see the turnscrew for the 2LED. But, as far as I know, I do not have auto leveling headlights, so the reset wouldnt work for me.
In case it is disengaged, where would I look to see if i had the self leveling headlights?
Thanks for the response..

 

pretty sure they all have it, just isn't advertised as a feature. There's a sensor on the rear suspension that makes it obvious.

 

How did you solve the problem?
