Air suspension

Guys car converted to steel suspension(98 reg P38) want to change back to air,just need to fit newair bags when funds allow(baby coming),any how when key on is telling me EAS manual,is this due to pump unplugged or are there fuses or relays need to refit to get the air system working.Have an Ethos code reader but no comms with EAS any ideas? thanks

you can get eas software free off net cable from ebay and plug it in to laptop.

you will need to find out whats there that shouldnt be, also you will need to find out why the sus was changed, if air pump or block then obviously fix these first!!!

Ok thanks,where would i be looking for the software?
