Have you added any equipment to the back of the car like a tow hitch? I would measure at the center of the wheel on both sides from the ground to the top of the wheel arch and see if it’s like 35.5 inches. I had a friend who exhibited the same thing you said and it turns out the air suspension dropped an inch when the tow hitch was installed at the dealership shortly after delivery.

Wait.....

2015 premium does NOT have air suspension so you can't really change the modes. Are you pulling our legs?

Thanks, but no, I have not added any new equipment. I will check the ground clearance.

Fadeyemi

Lol, well, mine does.
Will send a picture when I get back home from my trip.

Tire pressure is fine. I've checked it, dashboard low tire pressure light is also off.
Thank you

I checked . . my error. My car is the Luxury version

How many miles or kilometers are on vehicle?

Are you able to see the rear end of GX go up and down a few inches when you adjust suspension height?

Outside the vehicle can you hear the compressor when it is lifting the rear from low?

Any oil showing up on the shocks?

Do you know what diagnostic tool or software was used to troubleshoot? General OBD reader wouldn't pick up issues here.

Can you post pictures of the rear axle on both sides take from the rear and underneath showing the relation of the bump stop to the axle and also include air bags in the pictures?

Fadeyemi

Thanks for these helpful questions . . .
i. Yes, I am able to see the rear end of X go up and down when I adjust the suspension height
ii. Yes, I can hear the compressor humming as it does its job
iii. No, I can see no on the shocks
iv. No, I do not know the diagnostic tool or software used. It is these type of closed garages where you submit you car out front and it goes in the back for repairs, no access to the owners to get to the back
V. I will post some pictures . . .

Fadeyemi

... also, it has got like 60k miles on it

Fadeyemi: These Timbrens at least on the rear should help with impacts that are hitting the bumpstops.

You could also run your own scan with this:

Although if the shock valve adjusters on AVS were malfuctioning I think the suspension error message would show up on center screen.

What pressure do you run your tires at?

Are you able to tell differences on yours between Sport and Comfort mode?

Maybe some front pics as well.

Thanks!

I noticed something while looking at some Prado documentation and the Eurasian 460 FSM that high mode can be run up to 31 MPH versus 18 MPH for North American spec GX 460s. Module is almost $1K new so not interested in undertaking this potential mod myself.

[North American GX 460]


[Eurasian GX 460] - This could include GCC states as well / Take from Eurasian FSM





I wonder if this just dependent on what Suspension Control ECU revision is installed like a MTS module swap?

I see the following PNs for Suspension Control ECU

89293-60060
89293-60061
89293-60110
89293-60111
89293-60112
89293-60113

Anyone seen this before? It flashes for a second when I start the vehicle, but does not return, manual up down cycling of air suspension still works.

Can you check see if there are any codes stored?

Only code was for a seatbelt indicator light...Tesla style radio install
