Hi there,
Does the suspension height switch inside the vehicle operate?
Posted on Aug 06, 2011
You did not post the year so i will give you the most common way to raise the car with the most common system.
1st, find the DLC1 test conector under the hood on the right inner finder it will look like this.
using a jumper wire jump termanals Ts and E1
then push the "DOWN" button on the height select switch 5 times or more within 5 seconds after starting the engine.
if you have done every thing right up to this point the height control OFF light will start flashing at a .25 second interval.
now with the light flashing and the engine runing and the car in park turn the damping mode select switch to "COMFORT" mode ----- push "UP" and the front will come up and if you push and hold the height control switch and the "UP" button the rear will come up.
make sure you do not raise the vehicle height higer then the "HI" position when raising it with this test.
good luck
let me know if there is any thing else you need.

No, I had someone look at the car and he said the sensors are shot, need new ones, and they are $300 a piece. He somehow was able to reset the car height and left it at normal height and said it should stay that way. Lift conrol reads off. This was about 6 weeks ago and now the height is down and the car is not giving a comfortable ride, I will unhook the battery and hopefully it will reset. If not, what would be the solution. Thank you
Tried unhooking battery did not work. any other way to fix height problem as Lexus is low to ground and giving a rough ride. thank you
