I recently attended a high-speed lapping session at a not-too-distant track from here in Tx. An instructor took my car around the course for a couple of laps before handing the wheel (figuratively speaking) to me. Prior to his laps, I set the handling to "Competitive Mode." When my turn came, I switched on the ignition and received three Service warnings on the DIC: Service ABS, Service Traction Control and Service Active Handling. In the absence of those services, the car was downright evil but, I managed.
I asked our neighborhood Chevrolet dealer to effect a repair. After spending nearly a full day analyzing the problem (according to them), they called and said that my "ABS computer had to be replaced." It was not cheap (4 digits).
Was this a necessry expenditure or could someone other than the dealer when a penchant for computers, Corvettes, and low overhead possiblyu effect a more economical solution?
I'm new to Corvettes but, have been playing with cars since puberty (I'm not a new grandfather).
thanks in advance for your "Monday morning quarterbacking."

Just had to replace mine after the same symptoms and whatever the codes were(I don't remember the numbers, but I looked them up on the forum to determine the problem). Dealer cost was $1,900ish with part and labor. You can do the fix listed above for a lot less, or buy the fixed part and have someone install it for you. It will still be way less than the dealer. I was under warranty so I went with the dealer. If you're out of warranty you should definitely go the aftermarket route.
Rule number one with a C5 - *NEVER* assume that fault codes actually represent a problem. The systems are fairly decent, but far from bullet proof. Glitches can and will occur that trigger faults when no actual failure exists. Whenever you get a fault, first thing you should do is put the DIC in diagnostic mode and clear the codes out (you can do this for many of the codes while the engine is still running, contrary to GM's published instructions). If the failure is real, the code will come back immediately. No harm, no foul. If the failure isn't real, clearing the code will restore normal functionality. And if the failure is intermittant, clearing the code(s) might allow you to continue to drive the car and get it home, where you'd otherwise be forced to call for a tow.
The DIC "latches" some codes (safety related, mostly) and remembers them across some number of ignition cycles. So once you've the fault has been latched, the subsequent behavior of the system might lead you to believe the failure is permanent when it is not.
On my 98 Coupe that I owned before the Z, I had some kind of a major hiccup that triggered the "Service Engine Soon" fault and put the motor in limp home mode. The car was nearly undrivable in limp home. I pulled over and cycled the ignition a few times to no avail before deciding to try clearing codes in the DIC. Did so with the engine running and it made no difference. I thought I was screwed. But I tried it one more time without starting the engine - ignition to ON, clear codes, ignition to OFF, pause, ignition to START and viola! Problem solved.

I should have mentioned that my problem started as an intermittent no ABS/traction/Active Handling. I cycled my ignition and cleared my codes(same codes every time) several times over the course of about 3 weeks. It would usually reset. I kept driving it until it was no longer intermittent and would not let me reset it. It was at that point that I researched the codes online and then took it to the dealer under warranty.
Good tip to always try a reset first. I've had other codes that popped up once or twice, I've reset them and never had them again.
i just had this happen and all it was is that the passanger rear speed sensor came loose and needed to be recliped the the back of the rotor bracket! And all is well!
Paul, Turn around time was about a week, I didn't pay for faster shipping but you can recieve it back faster, I sent my module and got my module back. Also I requested any new mods that would help and they gave it to me for just asking. I think that it is somthing new that extends longevity. Jason will explain it if you go on their web sight.
