Electric Parking Brake System AUTO Function Circuit [01/2019 - 09/2022]: Description

for M/T 

1. The electric parking brake system AUTO function (IG-OFF linked function) is controlled by the skid control ECU (brake actuator assembly) based on whether it receives input voltage or not.

   When the engine switch is turned off, the electric parking brake system AUTO function (IG-OFF linked function) automatically operates to apply the electric parking brake.

for CVT 

1. 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.
