Nissan Rogue Service Manual: U1000 CAN COMM circuit
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle multiplex communication system with high data communication speed and excellent error detection ability.
Many electronic control units are equipped into vehicles, and each control unit shares information and links with other control units during operation. With CAN communication, control units are connected with two communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits and receives data but selectively reads required data only. Refer to LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart".
DTC DETECTION LOGIC
DTC detecting condition
|CAN COMMUNICATION FAILURE||U1000||When air bag diagnosis sensor unit is not transmitting or receiving CAN communication signals for 2 or more seconds.||Refer to SRC-95, "Diagnosis Procedure".|
DTC CONFIRMATION PROCEDURE
- Turn ignition switch ON and wait for 7 seconds or more.
- Using CONSULT, perform SELF-DIAGNOSIS RESULTS of AIR BAG.
- Check if any DTC is displayed in the self-diagnosis results.
Is DTC detected? YES >> Refer to SRC-95, "Diagnosis Procedure".
NO >> Refer to GI-41, "Intermittent Incident".
1.CHECK CAN COMMUNICATION SYSTEM
