Toyota Camry (XV70): Electric Parking Brake System AUTO Function Circuit
DESCRIPTION
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 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.
