DTC U1006-00: Lost Communication With Battery Energy Control Module 'A' (H-CAN): General Description
WARNING: This page is about a different car, the 2024 Kia Sorento. However, it is still accessible from the selected car via links, so may be relevant.
CANFD (CAN Flexible Data rate) is an improved communication system from CAN (Controller Area Network) communication. It is the same bus type structure as the CAN communication, and the data transmission speed has been improved from 1Mbps to 8Mbps. G-CAN and H-CAN are used for efficient information sharing between eco-friendly systems such as BMS, MCU and HCU and ECM/PCM.
Through G-CAN and H-CAN communication, each control unit shares important signals to perform efficient and optimal control.
