U1024 INFINITI Description
The Controller Area Network (CAN) is a serial communication line for real-time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Engine Control Module (ECM) and Variable Valve Event & Lift (VVEL) Control Module are connected with two communication lines (CAN H line and CAN L line) and transmit/receive data. ECM shares information and links with the VVEL control module during operation.
The Diagnostic Trouble Code (DTC) when the Variable Valve Event & Lift (VVEL) Control Module cannot transmit/receive can communication signal from the Engine Control Module (ECM).
