DTC No.	Detection Item	DTC Detection Condition	Trouble Area	Memory	Note
C13AD/23	Open in +B Circuit	All of following conditions are met: Engine switch on (IG) or electric parking brake switch assembly pushed to lock side with engine switch off. When parking brake is not operating: +B voltage is less than 7.79 V; when parking brake is operating: +B voltage is less than 3.21 V. Not operating: Approximately 1 second Operating: Approximately 0.5 seconds. HINT: *: This value is based on the assumption that the battery voltage is 11 V. The threshold changes according to the battery voltage. For details, refer to "Threshold Changes According to Battery Voltage".	Wire harness or connector Parking brake ECU assembly	Yes	An electric parking brake system malfunction is displayed on the multi-information display.
