Code C1310 Description

The Skid Control ECU communicates with the Hybrid Control ECU and controls braking force according to the motor's regenerative force. The Skid Control ECU sends Enhanced VSC signal to the Hybrid Control ECU and inputs operating signal from the Hybrid Control ECU. The Skid Control ECU uses CAN communication for communication with the Hybrid 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.
