service selective ride
Hello all,
I have a 2005 C6 with the selective ride system. I got some new tires put on by a mechanic other than my main dude, due to his garage not being able to work on run-flats. Anyway, when I got the car back I noticed a clanking in the front passenger shock. The tire guys were useless, pointed me in the wrong direction, and refused to accept responsibility for it. So I took it to my regular mechanic, who said it was the shock bushing. Rather than spend cash I didn't have at the time on a $1000 shock, he just replaced the bushing. The car runs fine now, just like it was in touring mode. However, the "service selective ride" message has been on since he replaced the bushing.
My question is: Is this problem attributed to the shock itself, or is there a separate controller that may have been damaged while the bushing-less shock was clanking around? Is there any way that I can figure this out without taking off the wheel?
(Before anyone jumps on me for not wanting to take the wheel off, this is the first car that I have ever had that I cannot even get a low profile jack under without touching the body, therefore if I can't fix it with ramps, it's off to the mechanic. Sucks, but it's the price I pay for driving a Vette and not having an in-ground lift.)
Thanks,
Marty

I don't know how you would adequately investigate the problem without taking the wheel off. May be possible but I'm not able to envision how. 
Anyway, there is the sensor and related electrical connector that could have been damaged. I think you need more than a basic code reader to pull those codes, probably a Tech II.

First of all, you can drive your car over 1 or even 2 pieces of 2x6 (or wider) to create the needed clearance for a floor jack 
.
As far as the shock, if you disconnect the harness from the main connector, system throws a code. If you only disconnect the main connector (the one that goes to the shock) by pushing the clip, it doesn't throw a code. I'd start by disconnecting the battery or removing the appropriate fuse, and if warning doesn't go away, then you have a real problem. If that's the case, I'd get the car on the air and investigate myself first. Good luck, and report back what you found.

Anyway, thanks for the tip. I'll check it out this weekend and report back.

Is the sensor an inseparable part of the shock, or is it something that the shock connects to, or sits in, or something? Is this the same as the controller units on the C5s?

No. The only electrical connection on the shock is at the top. You can clearly see and remove the passenger side connector by pressing on the metal 'bar', then pulling the connector up. But the driver's side requires removing the coolant overflow tank.
As far as the sensors, I haven't received my service manual, so can't answer that. But doubt they're the issue, unless they were molested somehow. The other things that might crap out due to being moving parts are the rheostats attached to the suspension, so check those with the car on the air. But keep in mind the rear has only one channel, so one of the 2 rheostats in the rear is for the HID's autoleveling feature. You can wait for somebody with a service manual to chime in, hopefully your same year, since the system has been improved a couple of times, I believe. Good luck.
