Manually activivating factory air ride pump?

[2UZ-FE]

Like everyone else who has a factory air ride model, mine **** the bed. Most likely due to the sensors rusting out. It's stuck in neutral height and the "off" light flashes. And of course there's no aftermarket lift options without converting to coils. But I just want to throw a daystar kit in the front, and somehow lift the back up so I can do some offroading before the season ends. Then in the spring convert to coils.

Is it possible to trip the motor and add air to the bags manually/vice versa to lower it as well?

I have the wiring diagram, and the motor is connected to a relay to the main 50A fuse along with 2 connections to the suspension ECU. Will tripping the relay add air? or does it need input from the ECU connections? I have a feeling the ECU connections are just for diagnostics/monitoring of the compressor motor. The other variable of course, is that pesty valve hooked to the air reservoir, which I assume is a solenoid.

Not sure on your question, but I think doing it this way may work (not sure if it will with it not working, but worth a shot). Setting rear Air height on 4R/GX and Prado - Toyota 120 Platforms Forum

Issue is my system does not function right now. I have to find a way to activate the compressor to get more air in the bags.

To put it in cole's:

System does not function due to faulty sensors
I want to trip the system to turn on the compressor and raise the rear end.
