Need help to understand DSC and TCS in my 2004 RX8. Everything was working fine until we change the OEM steering wheel for an aftermarket steering wheel with a short hub and a quick release. Now the TCS (Traction Control System) light turn on as soon the car start rolling and stay on until we turn the car off, which reset the system until we start running again. With the TCS On, I can't dissable or turn off the DSC through the console switch.

What I'm missing? Is there something, other than the air bag, in the OEM steering wheel that need to be in place so the system works? How I can achieved or troubleshoot this issue? Hope you can point to the right direction.

Thanks for the link, but sadly that's not the problem. The light go off as soon the car is turn off, but comes back ON a few seconds after the car start rolling again, but the DSC is off all the time. At that point the DSC can't be disengage or turn off, no matter what for how long I hold the DSC switch down. If I disengage both the DSC and TCS once I turn the car on, the DSC turn off when the car is running. Basically the problem start as soon we change the OEM steering wheel for the aftermarket one. Is there a sensor in the OEM steering wheel that we should keep?
