When you press DTC button once and you get DTC light on means you have turned OFF the dynamic traction control but it will keep DSC running. Now you’re allowing wheel spin only if you’re driving forward but in case of any side slipping the car will not allow the spin to happen and that, of course, to prevent drifting.
DTC has two major uses: to regulate traction and to enable sports-style driving while providing active stability control. When the drive wheels start losing traction the DSC automatically begins stabilization measures. The Dynamic Stability Control system curbs the engine output and stops slip on the wheels.
Dynamic Traction Control, or DTC, is a regulation system that controls stability and traction, allowing for sports-style driving, handling, and performance. As part of the Dynamic Stability Control system, DTC provides stabilization when you need it most, opening the door for tighter turns and controlled drifts.
