Abs Actuator and Electric Unit (control Unit)

Component Description

FUNCTIONS WITHIN THE SYSTEM

• The parking brake actuator is controlled by the signals from the parking brake switch, each sensor, and each unit.

  

  NOTE:

  The parking brake is released and applied by controlling the parking brake actuator.

• When a malfunction is detected, the system enters fail-safe mode.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

Controls the parking brake actuator.

PARTS LOCATION

Refer to Component Parts Location.

Parking Brake Switch

Component Description

FUNCTIONS WITHIN THE SYSTEM

Electric parking brake is applied/released by the parking brake switch operation.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

• When the parking brake switch is pushed / pulled, the circuit between the ABS actuator and electric unit (control unit) is established to input the switch signal.

• When parking brake is applied, parking brake switch indicator is turned ON by the ABS actuator and electric unit (control unit).

INDIVIDUAL OPERATION

Parking brake switch is constructed by a combination of normal open type switch and normal close type switch.

• Parking brake switch is pull: Parking brake is apply and parking brake switch indicator is turn ON.

• Parking brake switch is push: Parking brake is release and parking brake switch indicator is turn OFF.

PARTS LOCATION

Parking Brake Actuator

Component Description

FUNCTIONS WITHIN THE SYSTEM

The parking brake actuator activates / releases the parking brake by moving the piston of the rear brake caliper assembly according to the signal from the ABS actuator and electric unit (control unit).

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

Parking brake actuator is composed of a motor, gear, etc.

INDIVIDUAL OPERATION

It operates/releases the parking brake by transmitting the motor rotation output to the piston of the rear brake caliper.

NOTE:

Braking condition is mechanically maintained. It is not always controlled.

PARTS LOCATION

Refer to Component Parts Location.

CAUTION:

Never reuse the parking brake actuator if the parking brake actuator is removed from the rear brake caliper assembly.
