Electric Parking Brake System AUTO Function Circuit [11/2020 - ]: Description

The No. 2 skid control ECU (brake actuator assembly) receives shift position signals from the EV control ECU via CAN communication to control the electric parking brake system AUTO function (shift-linked).

The electric parking brake system AUTO function (shift-linked) is automatically disabled when the ignition switch is ON, the brake pedal is depressed and the shift state changed from P. Then, if the shift state changed from P, the AUTO function (shift-linked) automatically operates to apply the electric parking brake.
