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.
