Default Problem with C6 2008 NEW car....

Iím from BrazilÖ. and here we dont have GM dealer that knows about Corvette... I bought a new Corvette C-6 / 2008 (from Tom of Marrone Pines Blv - Miami). I shipped the car over sea until Brazil, they but the car in container and turn OFF the battery (negative).

When Iíve got I fix the battery (negative) after that I turn ON the car.

The car was all right but after first 200 miles some problems appear.

I was driven and some lights start to appear in panel, first Tire pressure, anti-lock brakes system, park brake light and air bag lights, torn ON too. At same time the warning messages appear on DIC :
- SERVICE ACTIVE HANDLING SYSTEM
- SERVICE ANTI-LOCK BRAKES
- SERVICE TIRE MONITOR
- SERVICE VEHICLE SOON
- SERVICE FUEL SYSTEM
I tried to stopped the car turn (engine off), waited 10 min. and started engine again. In a fill seconds the panel all lights came ON again.

Itís very stranger, at morning all the car/panel works fine in the first 8 min, after thatÖ. the Traction Control lights on panel turn ON Ö.and after more 3 min. other lights (SECURITY SYSTEM , ABS, AIR BAG, PARK BRAKE), turn on too.

Iíve check with SCAN tech-2, it lives some DTCs messages:

Curiosities :
PS1: - When a turned on the Traction control system( first 50 miles), the (TSC Traction Control system) light still ON in the panel. Is it common ???
The TSC was working, but I try to turn it off but it still working, I tried to slippery but the TSC doesnít turn OFF, and Iíve checked the ABS Brakes and it works too.
PS2: - Some times the watches in panel goes all DOWN ( Fuel, Battery, Oil pressure, RPM, Engine temperature and some times the lights too. It doesnít following a constancy. It works different every time, any time. (It works all right only at morning (first 10 minutes)
PS3: - When the problems appear in panel, Iíve observed that the turn lights work a little bit slowly in the panel, but the lamps out-side works all right.

Things that I already did:

1- I already double checked the BatteryÖ turn it off waited 30 min and turned on. But the problem still appear.
2- Iíve tried to change the battery, but still the same problem.
3- I checked the grounding near the engine and in the back off the car.

Any idea what is could be ??? What can I try ???

Please help me Ö.Iíll thank you for the rest of my lifeÖ

At a quick glance it sure sounds like a wiring or connection issue. Seems the error codes point to the BCM. I would check all the connections to the BCM which is located in the right foot well behind the carpet. Disconnect the negitive terminal on the battery first. Is there any change or sign the car had water around it?

With all the loss communication faults I think a loose connector is your problem somewhere in the car. I would check the fuses since the problem seems constant. A fuse could have been fried when the battery was connected.

The Traction control comment sounds somewhat strange. Push the button and the light will come on normally. The traction control is on when you start the car until you push that button. Regardless, I would try to figure out what the problem causing the codes are first.

It could be relatively simple to fix. Was the container water tight?

Disconnect the battery for a few minutes and then reconnect like he said.

If that fails, my second step would be to get a fresh, new, quality battery.

Good luck and let us know what happens.

BCM.
Do you have on star? GM has a TSB on the module.
Plug on the back of the tranny loose?, not clipped?

If disconnecting the battery does not solve the problem, I would try your local GM dealer. The dealer should be able to handle the problem because other GM vehicles use the same type of computer controlled system to operate the car. Although they may not know Corvettes in particular, they should be experienced enough through the repair of other GM products to handle this problem.

Best of luck.

Onstar can do a vehicle diagnostics. I say check fuses and then disconnect the battery to clear bad codes.

On star module is under the pasenger seat? There is a recent GM TSB on 2008's on faulty OnStar modules.

Do you have an aftemarket stereo?

"Aftermarket stereo" means, do you have a new radio/stereo? If you have only the original stereo that came with the car, that's fine.

By the way, Karl K, I thought the OnStar module was the black box located to the right of the inside mirror, high up on the windshield?

Your english is fine, Tiago.

Is the car stereo the original car stereo from the factory? Did you add any options at the dealer or by yourself? I would take it to a GM dealer. It doesn't matter that they don't have specific Corvette dealers near you, a GM dealer should be able to help.
