Anybody got an ENGLISH instruction manual/booklet
for this THING ? ?

My Dad's Celsior has one fitted to control the suspension,
but,
the manual is in Japanese ! !

Air suspension controller!!!!!
Has anyone got an English copy of the manual for this thing? I'd pay for p&p if I can get a copy of one and copy it!

Air suspension was available on US models. You should be able to workshop manuals from US dealers. Wiring diagrams would also be available from alldatadiy.com etc. There shouldn't be too many differences between the LHD and RHD models.

Hi
I have a 91 celsior with the same suspension problem.could you give me any advice on kickstarting the air suspension or replacing it with a less expensive option?? also looking for english hand book or manual for selsior

you can consider removing the air suspension and put in some 'normal' shocks and springs.

Or, you can put in some lower springs/shocks or even coilovers

Sorry, cant help if you an aftermarket air suspension controller, but if your Celsior has the standard air suspension, and its not working, has sagged low, or the dash 'NORM" light is blinking, first check that the suspension 'on/off' switch is turned on.
Its in the boot inside the tool kit compartment on the left side.
Apart from that, its just the normal 'Tems' (Toyota Electronically Modulated Suspension) sport/normal setting, or the 'Height' high/normal switches on the console next to the shifter.
