A common issue with the air suspension on the Lexus LX570 is it activating incorrectly and not deactivating when needed. To troubleshoot, start by inspecting the pressure switch in the air system. If the switch is faulty, the air supply won't fill, causing the vehicle not to lift. Test this by lifting the vehicle with a jack and placing it on jack stands, then draining the air tank using the drain plug at the tank's bottom. Next, start the vehicle to activate the pressure switch and use a test light on the wiring to check for proper connection. If the light doesn't illuminate on both ends, check the fuse and replace if needed. If the fuse is fine but the switch remains unresponsive, consider replacing the pressure switch.
