Hi Maxx,
You have a control unit, a height control sensor, the struts, which have o rings that could be leaking down, valves and dampers, an airbag cylinder and an actuator. It is possible that fault diagnostics would help, but from what I know about this, sometimes even the Lexus dealerships are at odds with the causes of the suspension failure, oh they fix it, but usually by over kill, replacing sensors actuators and shocks to make sure they cover all the bases. Most who experience this problem on a Lexus with any age on it use a conversion kit and change out the shocks and eliminate the automatic air ride system. These kits start at about $250 and go up to around $800, and still cheaper than the repair at the dealership. If you have a bad sensor or actuator, you'll get out cheap if you do the repair yourself or at a reliable mechanic. If you go to the dealer...hold onto your wallet. I have attached a pic that shows the components and their location. Good Luck. I hope this is very helpful!

Air bag suspension system wont inflate on 1992 lexus ls 400


The first thing to check would be the compressor, check all fuses and see if compressor is running.

i can tell you that most air bag systems develop a leak in the bags and the problem is not fixed inturn the air compressor runs so much to fill leaking bags that it over heats and destroys the compressor. most of the time the compressor fuse will blow, so check fuses first and then compressor. I have never seen a 1992 lexus with air bags.

Lexus ls 400 air suspension stop working


If this light is flashing, there is a problem somewhere in your air suspension system. You can check to make sure its powered on in the trunk on the driver side. Behind the carpeting. This is a common issue with that particular year and model. The system tends to go bad righ around the 15 year old mark or so. Also if the light is flashing, the system is not working. Your just riding on the regular suspension.


Hope it helps
