Air suspension problem.

[frank watt]

Morning, Lexus RX 300 on 05 plate. Air suspension. { recently had front N,S suspension unit replaced ( leak on old one) Suspension refuses to operate to come up and consequently bouncing down road. Have had air compressor changed, whole system air and smoke tested, all lights on  dash working yet no response from sus.Is there a particular sequence that should be followed to correct this for re-set. Pressure on compressor producing app 75psi

If the compressor is producing air but the suspension refuses to rise then logically there's a blockage somewhere in the piping that's stopping the air getting to where it's needed?

After a quick google search I found very similar symptoms on another forum site where disconnecting the Battery for 15 minutes then reconnecting sorted the problem.

Apologies, welcome to the LOC Frank 😀

Has the height controller for the low corner been checked? It needs to signal for the air to go to that leg.

... and not switched off with the tiny button, low down in the driver foot well?

Any progress, Frank?

Morning Piers, no progress as yet as i am at present de-mounting all four sensors, cleaning them and replacing. I am then going to replace air pump (generator ) at rear offside as i have acquired one that is "guaranteed "  If I have not already mentioned fuse no 29 ,Air suspension which is a bolt in species involves the removal of the whole fuse casing by auto elec (£ 40.00) who also replaced the app relay.

Thanks for the interest from all forum members will keep you all posted! Regards from a cool and windy Nairn

Thank you. A great update. It sounds like quite a job.

I hope it all goes well.

Frank, As Piers said - thank you for the update - and I too hope all goes well......

I have a thought that owning an RX is just like owning a cat - we don't own it - - it owns us!
