Technically no--the compressor on the engine will begin inflating the air bags as soon as the engine starts. Never tried this but am told you can hold down the "dump" button on the HWH panel to keep bags from inflating. But why would you need to do this?

He needs to pull the coach into his garage and it only clears when it is lowered. LOL just guessing.

Steve, when you say "unplug" could provide some detail?

Try opening the purge vale in the service bay.

Tim - On the bottom of my compressor there is a two wire cable with a connector that plugs in to the bottom of the compressor. If this is disconnected no power will be applied to the compressor...therefore no air in the bags.

Interesting--don't recall a 12v compressor plug on my 03 [ISL400]--could this be an ISC 350 thing?
