Service Air Suspension?

[CBR_Raven]

ok, i just changed out both of the rear suspension air bags and now it's reading "service air suspension" it was working fine after the bags were installed but now i don't hear the air compressor turning on. does anyone have a clue what the problem could be?

Try disconnecting the neg battery term. for 10 mins to reset the computer.

Make certain that the valve cap is on your compressor nipple.

where would that be located? i only replaced the air bags...i didn't touch anything else.

It's the fitting by your air compressor switch to whitch you attach the tire filler hose. It looks like the top end of a schraeder (tire) valve. Leaving it uncapped will produce the exact problem you describe.

i've never had a cap on that valve but i will be sure to put one on it from now on.

I have never had a problem without a cap on my hose fitting. I think I lost it about a month after I got the car. 2 years and no problems. If you're losing air thru that fitting, I'd say theres something wrong with it or the compressor wouldn't ever turn off.

CBR : I replaced an airbag on my rig once, (2 days old) and we didn't have to recalibrate the computer.

Anytime any air suspension components are changed A ride height calibration needs to be done which to my knowledge only the dealer has the right tools to do. Need A tech 2 scan tool and ride height calibration blocks. The light may be out but that doesn't mean ride height is learned.

ok, i'll keep that in mind. however, everything seems to be fine for right now after i disconnected the battery for a while. i'll keep an eye on it to see if anything changes. i would hate to have to go to the stealership just to get the system calibrated...i'm sure they would charge me at least $120 flat rate.
