DTC C1310/51 Malfunction in HV systemDESCRIPTION
DTC Detection Condition:
The skid control ECU communicates with the HV control ECU and controls braking force according to the motor's regenerative force.
The skid control ECU sends enhanced VSC signal to the HV control ECU and inputs operating signal from the HV control ECU.
The skid control ECU uses CAN communication for communication with the HV control ECU. If a communication malfunction is memorized, the skid control ECU prohibits enhanced VSC operation and a part of electronically controlled brake system control by fail-safe function.
C1259/59 is stored if the power switch is turned ON (READY) with the HV battery service plug disconnected.
HINT: This DTC is output from the skid control ECU when the HV control ECU sends a malfunction signal to the skid control ECU.
