BTCS ( Brake Traction Control System ) is operated when the value ( Wheel acceleration value + speed difference value ) exceeds the specified value when vehicle speed is lower than the 50 Km/h.
The BTCS intalled HECU calculates the DISC temperature logically, which is an assumed value, by using the value of Wheel speed, vehicle speed change, control mode and BLS(Brake Lamp Signal) signal.
Assumed DISC Temperature is used to protect DISC overheating, caused by long-time operation, which may cause a decrease in brake efficiency.
The HECU calculates a disc's temperature for a normal operation and if the calculated disc's temperature is over 500 ℃(932 ℉), this DTC is set.
