Not heard of it on here before but it sounds like the TC part of the (ABS) computer logic.

Mine has a light that flashes if TC is activated (you have to try quite hard on normal roads in an STR to make it happen). Is yours flashing (it'll be brief I expect)?

Assuming (gulp!) the sensors etc are OK now, check the wheels & tyres very carefully in case of lumps, mis-shapes, odd tyre pressures or and I do mean this different size rims or tyres!

 

I have a 2004 s type and i have a dsc not available poppin up (no other codes) and im wondering if it can be from my battery .. it only holding 9.0 volts when the car is off.. what do u think?

 

Hello, and welcome to the forum. Yep, 9.0 volts is bad. That is extremely low. There's a slim chance you've got a good battery that is just discharged, but most likely the battery itself is toast. If the battery is more than a few years old, I wouldn't even mess with it, and just replace it. Such an extreme discharge typically damages the battery. Make sure the new one is fully charged, as they often only have a partial charge from the parts store.

Once installed, make sure your charging system is up to snuff. Your car has a smart charging system. Right after engine start, you should see around 14.5V as measured at the battery, tapering off around 13.5 after a few minutes.

Lots more details here about problems caused by low prestart voltage:
