DESCRIPTION

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	Memory	Note
C13A0	Open circuit in Power source circuit	Both of following conditions are met: Ignition switch ON or electric parking brake switch (integration control and panel assembly) pulled to lock side with ignition switch off. Parking brake ECU assembly's power source relay is open for approximately 0.5 seconds.	Parking brake actuator assembly Parking brake ECU assembly	Yes	An electric parking brake system malfunction is displayed on the multi-information display.
C13A5	Electric Current of Motor	One of the following conditions are met: Detection conditions (1) Ignition switch ON or electric parking brake switch (integration control and panel assembly) pulled to lock side with ignition switch off. Parking brake ECU assembly's internal current is abnormal for approximately 0.1 to 0.5 seconds (differs according to malfunction contents). Detection conditions (2) When current zero point calibration is not completed within 3 seconds after turning the ignition switch to ON	Parking brake actuator assembly Parking brake ECU assembly	Yes	An electric parking brake system malfunction is displayed on the multi-information display.
C13B0	Electric Parking Brake ECU Malfunction	Both of following conditions are met: Ignition switch ON or electric parking brake switch (integration control and panel assembly) pulled to lock side with ignition switch off. Internal current of parking brake ECU assembly or ECU components abnormal for a maximum of 60 seconds (differs according to malfunction contents).	Parking brake actuator assembly Parking brake ECU assembly	Yes	An electric parking brake system malfunction is displayed on the multi-information display.
