SIGNAL PATH

When Operating The Parking Brake 

• The electric parking brake control module receives a parking brake switch operation signal from the parking

brake switch is pulling.

• The electric parking brake control module transmits a electric parking brake indicator lamp signal to the com-

bination meter via CAN communication according to the received electric parking brake indicator lamp sig-
nal.

• The combination meter turns ON the electric parking brake indicator lamp when receiving a electric parking

brake indicator lamp signal.

When The Electric Parking Brake System Is In Abnormal State (Blinking)

• The electric parking brake control module transmits a electric parking brake indicator lamp signal to the com-

bination meter via CAN communication when detecting a malfunction (following condition) in the electric
parking brake system.

- When a status cannot be judged between applied and released.
- When the parking brake switch is operated under the condition that the parking brake switch is malfunction.
- When the parking brake switch is operated under the condition that the parking brake actuator is malfunc-

tion.

- When the initial position adjustment of the parking brake actuator is incomplete.
• The combination meter blinking the electric parking brake indicator lamp when receiving a electric parking

brake indicator lamp signal.

• For the relationship between indicator lamp and DTC, refer to 

PB-36, "DTC Index"

.

LIGHTING CONDITION

When any of the condition listed below is satisfied while the engine is running:
• Electric parking brake is engaged.
• When the parking brake switch is pulled while driving the vehicle, resulting in parking brake activation.
• While measuring braking force.
• For the relationship between warning lamp and DTC, refer to 

PB-36, "DTC Index"

.

BLINKING CONDITION

• When any of the condition listed below is satisfied while the engine is running:
- The combination meter not receives a signal from electric parking brake control module via CAN communi-

cation.

- When the electric parking brake system is not activated. (Unable to judge malfunction) 
- When the parking brake switch is operated under the condition that the parking brake switch is malfunction.
- When the parking brake switch is operated under the condition that the parking brake actuator is malfunc-

tion.

- When the initial position adjustment of the parking brake actuator is incomplete.
• When the parking brake is not automatically activated even when the ignition switch is turned OFF.
• For the relationship between warning lamp and DTC, refer to
