DTC    C1310/51    Malfunction in HV system

for Preparation Click here


DESCRIPTION

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 ECB control by fail safe function.
C1259/59 is stored if the ignition switch on with the HV battery service plug disconnected.

DTC No.
