Electric Parking Brake System AUTO Function Circuit [09/2020 - 11/2021]: Description
WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2024 Lexus IS 500, 2024 Lexus IS 350, 2024 Lexus IS 300, 2023 Lexus IS 500, and 2023 Lexus IS 350. 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 ECM 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 engine switch is on (IG), 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.
