Default CCR test?

ok, i've been doing some thinking and i'm not really sure if the CCR option is really working or not. i know for a fact that the ELC is just fine so the compressor works. I think i feel a difference in the ride but its so little of one that i might be immagining it. so how can i tell if those buttons are really causeing anything to change when i push them?

Ride shotgun. Have your driver change suspension modes while you have your eyes closed.

The difference is very subtle. In effect, if you have no faults in the system, it works. But just as with all gas-charged struts (which the CCR struts are), as they age, performance decreases. CCR struts will degrade over time to the point where the two modes feel very similar.

Myself and Haro ... were both able to feel the difference plenty... but as Willwren mentions..age could play a large factor.

If the lgihts work properly..assume it'* working and the system detects no faults....the struts are worn .

nope cause when you replace the Struts you disable the CCR and move on....Most aftermarket Struts are better than the OEM in Perf mode

CCR is built into the strut, and nobody builds it in anymore.

I went the route of finding a low mileage 98 with working ccr and pulled all the struts and replaced mine. my problem was a busted rear bellows for the elc, and didn't want to loose ccr.

Aftermarket struts will perform FAR better than CCR in Performance mode.

I have two cars with FE2 suspension. My SSEi does not have CCR, and performs WAY better than the SLE in Performance mode.
