Electric Parking Brake Control Module

INFOID:0000000010318117

• The parking brake actuator is controlled by the signals from the

parking brake switch, sensors, and units. 
NOTE:
The parking brake is released and applied by controlling the park-
ing brake actuator.

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

Parking Brake Switch

INFOID:0000000010318118

• Pulling the parking brake switch applies the parking brake.
• Pressing the parking brake switch releases the parking brake.
• When the parking brake is applied, the parking brake switch indica-

tor turns ON. In addition, it turns OFF when the parking brake is
released.

Parking Brake Actuator

INFOID:0000000010318119

• The electric parking brake control unit (1) sends the signal form the

harness (2) to the electric parking brake actuators (3) to apply and
release the parking brake.

System Description

INFOID:0000000010318120

• When the parking brake is being operated, the electric parking brake indicator lamp in the combination meter

and the parking brake switch indicator turn ON.

• When the parking brake is released, electric parking brake indicator lamp in the combination meter and the

parking brake switch indicator turn OFF.

• This sends the parking brake switch operation signal to the electric parking brake control module.
• The electric parking brake control module drives the motor in the parking brake actuator.
• The motor generates the rotational starting torque, which is transmitted to the rear calipers to apply and

release the parking brake. 

• When a malfunction occurs in the system, the Parking brake warning lamp (yellow) turn ON and the function

for entering the fail-safe status is held. 

• When parking brake switch is pulled/pushed during system malfunction, electric parking brake indicator

lamp blinks and Parking brake warning lamp (red) turns ON when electric parking brake cannot be operated.
It restricts braking and release operations of electric parking brake.

ELECTRIC PARKING BRAKE OPERATION

Normal Operation

• When the parking brake switch is pulled while the vehicle is stopped, the parking brake begins to be applied. 
• When the parking brake braking force reaches the prescribed value, the electric parking brake indicator

lamp turns ON.

• When the power switch is turned OFF, the electric parking brake indicator lamp turns ON for few minutes

until vehicle sleep.

Normal Release (power switch ON)

BCM

Mainly transmits the following signal to electric parking brake control module via CAN 
communication.
• Stop lamp switch signal

Combination meter

Mainly transmits the following signal to electric parking brake control module via CAN 
communication.
• Seat belt buckle switch signal (driver side)
Mainly receives the following signals from electric parking brake control module via 
CAN communication.
• Parking brake warning signal
• Electric parking brake indicator lamp signal
• AT/CVT:

Mainly transmit the following signal to electric parking brake control module via CAN 
communicatoin.
