2007 lexus ls460l air suspension is at very top! Can I reset it
Hey fellas, I woke up this morning got in my car and the suspension is as high as it can go the car drives like a Mack truck and it's flashing check suspension.
it's -10 Celsius here in Canada and I'm wondering if that had something to do with it this is never been a problem before does anyone know how to reset the system I've already tried to reset through ODB clear all codes and also pulling the battery it's absolutely a misery to drive please someone help me

hmmmm I wonder there must be a suspension ecu if I could find it I would pull the fuse on it after I disconnect both battery terminals as well as the main ecu fuse the leave it off for a good 30-40 mins the fuse back reconnect best thing I can think of.
Unless you have techstream I am sure there’s a fix there. But I don’t have it so can’t advise. Let us know that happens good luck

Great news I took it to a mechanic buddy of mine it was slow today so I spent a bunch of hours with him and found out that it was just a bad faulty wiring on one of the units fixed it for about a hundred bucks now the car drives like a dream again

Oh, no.
"Resident expert"...that's the kiss of death, right there.
I've found, there are really only two ways to diagnose this system, one for hardware, one for software.
Software = Techstream There's no way around this, if you want to keep it OEM.
Hardware = start taking stuff apart
I'd wager the damaged wiring was near a rear corner's height sending unit. It's a rheostat with an arm attached to the control arm while the main body of the component rides on a fixed part of the chassis. A simple, but critical, piece.
The suspension's mechanical design is fairly simple and straightforward. Now, the combo of physical and computerized aspects of this suspension design...that's another kettle of fish.
Timarm, I'm glad you got it sorted, and for next to nothing, money-wise!
