Replaced Airbags with Coils - Service Air Suspension Light stays on???
My '03 H2 went through two compressors when I said enough is enough. I went to a spring shop and replaced my airbags with coils.
Ride height and overall right is just as good as before.
My only problem now is "Service Air Suspension" light in the DIC stays on!
Is there a fuse or relay that I can remove to stop the message from displaying all the time?
I tryed unplugging the compressor harness but it didn't do anything.

Got tired of mine too  http://www.elcovaforums.com/forums/s...ad.php?t=24471
Look in the front drivers side fender well for a wiring harness that has a relay plugged into it, remove it, it is for the air suspension.
It will be just to the right of the shock tower in this pic. I took all the air suspension parts out, wiring and all but in there is a relay, try it and see if the light goes out, may have to pull negative lead on battery for a bit to clear codes/warning after taking it out.

Re: Replaced Airbags with Coils - Service Air Suspension Light stays on???
Thanks for the info Ed. I found the relay.
Can I just cut the whole thing off? I tryed unplugging it, but it seems that only one end can unplug exposing the prongs.
Can I leave it like that or does that whole thing need to come out?
Thanks.

Don't have a answer for ya on that, might pull the relay and wrap electrical tape around the plug to seal it off, at least to see if the warning goes out. All those wires are gone on mine, all the way back....and everything else too.
When you unpluged the module on the compressor did you pull the negative lead on the battery to try to clear codes/warning ?

OK, wrapped the end with electrical tape, pulled negative lead for about 15 mins.
Started it up and NO "Service Air Suspension" light!!!
Whoo Hooo... thanks ED!
I will drive around tomorrow a bit and see if it stays out.. i got a feeling I won't see that notification ever again!!!

Tried Quick Pull for the BlackBerry ? I have the Storm and used it until the BB's software version went to from 4.*.*.*** to 5.*.*.*** and found that Quick Pull does not play nice with the version 5 yet.
Ever hear of CrackBerry.com ? good site for the BB's
