General Description

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 installed 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 SIGNAL. Assumed DISC Temperature is used to protect DISC overheating, caused by long-time operation, which may cause a decrease in brake efficiency.

DTC Description

If the HECU decides that the Disc is over-heated (above 500 °C), then it turns the TCS lamp ON and inhibits BTCS operation to protect overheating of the disc. If the calculated temperature becomes lower than specified value (approx. 250 °C), then the HECU turns the TCS lamp OFF and operates the BTCS again.
