Active Trace Control Function

Intelligent brake assistance OFF indicator lamp turns ON when a malfunction occurs in the system [ABS actuator and electric unit (control unit)]. The control is suspended for Active trace control function. The vehicle becomes the same as models without Active trace control function.
CAUTION:
Lamp ON condition of intelligent brake assistance OFF indicator lamp is that intelligent brake assistance OFF switch is in the pressed and not turned ON status.
Mode is fixed to the mode when a malfunction occurs if CAN communication malfunction (DTC "U1000", DTC "U1010""U0424") occurs between ADAS control unit and A/C auto AMP. The mode is fixed to STANDARD mode after ignition switch turns OFF to ON.
