DTC B2785 COMMUNICATION MALFUNCTION BETWEEN ECU CONNECTED BY LINCIRCUIT DESCRIPTION
DTC Detecting Condition:
The smart key system uses the LIN communication line for communication. LIN communication sends and receives signals by serial communication, and connects with CAN and multiplex communication via the gateway ECU.
The LIN communication bus directly uses battery power. It consists of a single wire which only uses the transceiver and pull-up resistance of the open-collector.
