Howdy. My 13 RX used to have xenon lights. They were replaced by standard halogen headlights at some point and the sensors for headlights leveling system were just sitting under the hood at a leveled position. From time to time they would give me a warning saying system is not working. I would re adjust the sitting position of those sensors and all would be well.

This time no amount of wiggling helps. Either one of the sensors died or I dont know. They dont make any noise or move up or down trying to make an adjustment.

Carista app shows b2424 code and cant reset it.

What can i do to disable the system? Or to get rid of the warning light on the dash which is very annoying.

Thank you.

 

I am not sure I understand. HID headlights are totally different than the halogen. The halogen, to my understanding, never had the auto leveling capability. Why would you replace the HID with halogen and expect there to be no problems?

 

It was done before my purchase.

 

Anyone ?

I bought a spare headlight motor but that didn’t solve the issue.
I used Carista to check for Codes, before it used to tell me that the left sensor is bad. Now it doesn’t come up with a code, but the dash message still says headlight leveling system check.

Anyway to by pass this feature since it’s not working anyway ?

Thanks.

 

It might be possible to disable AFS from the steering wheel multifunction display controls? On my 2010 I can disable it this way, but I don't know if that will prevent AFS errors from being displayed.

 

Thanks but that’s not an option. 2013 I think is the first year of the face lift. Few things changed.

 

I bought adaptive light sensors for both sides. I can see them moving and making adjustments when I start the car. I ran an OBD scan with carista app. Before I would get a code for one of the sensors. Codes are gone. Still the message on the dash come on to CHECK ADAPTIVE HEADLIGHTS.
I even disconnected the battery to clear the codes. Still the message come on.

Is there a module I can disconnect at this point?

Thanks

 

The adaptive headlight system is not the same as the leveling system. Adaptive refers to the side to side movement. The self leveling system runs on sensors in the rear to accommodate different loads. My 2015 has self leveling but Lexus did away with the adaptive system after 2013. (I think) My 2015 does not have adaptive. I have the adaptive system in my 2006 SC430 and in my opinion it is of very little value. I guess that is why Lexus discontinued it.

 

I appreciate the input, but does anyone know how to make the message on the dash go away.
