2016 gx460 Air Suspension Stuck on 'high' setting

[mattds]

Hi All, so here is what i have tried so far. I have a 2.5" Fox Front lift and for the last 3 years i've had the rear air suspension 'adjusted' up to match, it's been good offroad. (i have a bunch of other mods, but unrelated to this). This also all started after i was carrying a heavy load that required the air suspension to increase pressure to keep the ride height level.

- reset the air suspension ECU using the jumper from pin 4 to 13...although it's possible i didn't do this correctly? it went into air suspension diagnostic mode, but pressing the brake pedal down 8 times did not seem to do anything.
- checked the two fuses under the hood (is there a relay?)
- I have no error lights
- I've checked that my little swing arm that you can adjust to 'lift' the rear is not sized
- When i go down to 'low' it does not let any pressure out.

I could switch to coils, but believe it or not i like the adjustability and do at times carry heavy loads, etc.

Any other suggestions?

Thanks
Matt

Is it not on high all the time considering you have the 2.5" front lift?
Or it is on high but very stiff ride because of the rear being over pressurized?

Hey, no it's still on the 'high' setting. Even when i adjusted it up, i only had to raise it about 1". So on the high setting it sits about 2" higher then the new norm. It's the strangest thing. I know poeple pull the bags, but i really like the adjustability and i've had no issues so far. Granted i know i would get more flex if i pull the bags...ugh.

I would also try to leverage Techstream and/or OBD Link. You can test components with TS though.
