Electric Parking Brake System AUTO Function Circuit [11/2022 - 11/2023]: Description
WARNING: This page is about a different car, the 2025 Toyota Corolla Cross, 2024 Toyota Corolla Cross, and 2023 Toyota Corolla Cross. However, it is still accessible from the selected car via links, so may be relevant.
The skid control ECU (brake actuator assembly) receives shift position signals from the TCM via CAN communication to control the electric parking brake system AUTO function (shift-linked function).
The electric parking brake system AUTO function (shift-linked function) is automatically disabled when the ignition switch is ON, the brake pedal is depressed and the shift lever is moved out of P. Then, if the shift lever is moved to P, the AUTO function (shift-linked function) automatically operates to apply the electric parking brake.
