bleeding air from read height control system

bleeding air from rear height control system

hey guys...some background...last week my wife was going into a pretty low parking garage so she hit the lower button on the rear suspension. system went nuts after that. When she got home I went under the truck and noticed that the driver side bracket that connects to the frame for the sensor had split. This was due to the sensor being frozen and not allowing the movement required when she dumped the air from the airbags.

I managed to get the system to re-inflate the airbags to normal height...but stupidly I didn't pull the fuse. I have sourced a new-used sensor but haven't had chance to get it installed. We were about to leave the house today and somehow the system got it into it's head to raise the rear end waaaaay up!
I can't get it to dump the air via the control in the truck.

Does anyone know how to manually dump the air? I won't have time this week to swap the sensor (13 years of canadian winters have made the connections a bit of a pain to undo) so I was hoping to get the truck driveable till at least next week.

Help!
Thanks all!

I don't have a definite answer to your issue, but thought I would share this link to a pdf of the RAS:

It would look like you need to access the exhaust solenoid valve at the compressor - but this is just a guess on my part.

I would refer you to fellow member ARK_SWAMP_RIDER for his expertise.

thanks... before I went to bed I realized that since I had the replacement handy I could just crawl under the truck and hook up the new sensor temporarily to drain the air out and get it back down to normal height.
I did this and got the truck down from skyjacker mode...lol.. pulled the fuse afterwards so it wouldn't re-inflate.
Still need to actually pull the broken sensor out. Stupid that toyota put something so finicky in an area that would get hit by all the winter crap.
