EC-308 < COMPONENT DIAGNOSIS > [VQ40DE] P0607 ECM P0607 ECM Description INFOID:0000000005257302 CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul- tiplex communication line with high data communication speed and excellent error detection ability. Many elec- tronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only. On Board Diagnosis Logic INFOID:0000000005257303 This self-diagnosis has the one trip detection logic.
