Note:..It should be no need to adjust the adjustment bolt. Look at the first pic when I said " I moved it in every position and had no luck" on page 3.( I think everyone that couldn't fix it was moving the same part) Also note the elbow part in that pic is also in the up position. I got that pic from the IS side. Thanks guys

so if you lower your car differently front and back, what happens is that the computer "thinks" your car is pointing one way and want to correct it, but if it falls out of range then the light comes on.

so the way to fix it is by adjust the leveling sensor so it's within range again. and that's why doing alignment wont' change anything, it's about how your car is lowered.

and also, you need to adjust it smartly as well. as i explained, when you adjust the sensor, you are adjusting how the computer thinks of the "inclination" of the car is. if you adjust it too much, maybe it's within range again and the light it gone, however the headlight might be pointing at the wrong direction still. so you should always do this where you can shine the headlights on a wall or so to make sure it's not shooting too high

Would an 06 - 2013 IS 350 experience the same issue if, installing shocks / springs from the Sport Tuned suspension into base IS 350?
