Lexus LS 460 air suspension issues

[Duncan chapman]

Looking for some advice really. I had my ls460 on axle stands for 6 months. The Battery died. When looking to get it back on the road I took it off the axle stands and the driving height has dropped right down. I then connected a fully charged Battery expecting the compressor to kick in and nothing. 

I have tried disconnecting the negative terminal for 30 mins then connecting again and nothing. 

im guessing there needs to be some re calibration or maybe some fuses or relays have gone……….

Any help is much appreciated

I believe you need to start the engine. The compressor draws a LOT of current so the engine needs to be running or it won't run.
Otherwise check the height sensors were not dislodged when it was on the axle stands.

Good and simple point by george above.

I had to put mine on a longer charge before the suspension started working correctly. I did a Battery recondition as well. Sometimes takes 10-20 miles of driving to work
