The BTCS / HECU calculates the DISC temperature by looking at the Wheel speed, vehicle speed change, control mode and BLS(Brake Lamp Signal) signal.
The calculated DISC Temperature is used to protect DISC from overheating caused by over use 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.
