I would prolly check the connections, and fuses first to see whats going on. Its really easy to take out the assembly (im guessing you already have taken it out to change the wedge bulb).

Do all the connections line up? might want to look for a busted headlight on ebay and grab the leveling motor.

Edit: Do both of them not work? or both of them work but the message still shows up?
if its the ladder, i would check the leveling sensors.

Quote: if both are down id check the connections at the headlighs and then try to find a new headlight ECU.

other possibility is that its a wheel sensor (one of the 4 sensors at each wheel for the leveling system)
Pure, does the car need to be on the ground then? Right now car has no wheels and is on jackstands due to coilover conversion and brake upgrade.

Ok, first of all, congrats on the 98, just found out. Power to the 2.5gen crew

Second, try this. Turn on your headlights, then start your car, and see if they headlights move up and down. check both of them. If they both go up and down, its most likely the leveling sensors.

Thanks Grand its nice to move up, (Ill miss the firt gen its been fun)I had a oppurtunity I couldnt refuse. 500.00 more for this car than I paid for the 93 a year ago! Car will be back on the ground tomorrow so i will see if they both move and go from there. Are the wedge bulbs DRL or just a accent light?

In case this can help someone.
The Lexus manuals are useless for this problem.
There are 2 motors which consist of each headlight adjustment.
There are only 2 sensors which are located on both right front and rear lower control arms. They have a large "n"looking hoop to allow the sensor to be adjusted up and down.
The arms usually bend and need to be straightened out every so often to work properly. The front sensor never needs adjusting so leave it alone.
When the car is started it turns the system to do a check and raises the lights to max up and down position before leveling out. If you get a "headlight malfunction on your readout after driving for a few meters and have an ABS light it is because the ABS light is on and disrupting the system. Fix the sensor and it will disappear. If you disconnected the arm and left it hanging it still would not trigger a fault on the ecu for having no change in output.

How do i know these things?
I bought my car and noticed the rear sensor was hanging. No issues with it not working except blinding oncoming traffic. Fixed it 3 times by welding it ,but it kept snapping off for some reason of torsional pressures.
Had my car worked on by the dealer and they broke a ABS sensor which threw my headlight sensor on also. Could not figure it out for weeks as i waited for the sensor to be installed. Realigned the arm and no change. As soon as the sensor was fixed the light disappeared .
I am now a sane man again with no dash lights.

im still having this problem and i have had my car in the air several times doing other things but never got back to the leveling. it drives me carazy but i just click the button and learn to live with it. i never could find the sensors or i justdidnt recognize them so ill go back under when the rain dries up and see what i can do. thanks SK

sha4000, before getting deep into this, try something very simple, disconnect the battery and reconnect one minute later. Sometimes that's all it takes to "clear" things up.
