CAN COMMUNICATION SYSTEM (for RHD), Diagnostic DTC:U1002 (CAN No. 2 BUS)

DESCRIPTION

• The network gateway ECU stores this DTC when no signals can be received from the ECUs that have been memorized as those connected to the CAN movement control bus.

• When the network gateway ECU receives a response signal from the ECUs connected to the CAN movement control bus, the network gateway ECU recognizes and memorizes that the ECU is connected to the CAN movement control bus. Based on this memorized data, the network gateway ECU monitors for malfunctions in the ECUs connected to the CAN movement control bus when communicating with those ECUs. If the network gateway ECU cannot receive response signals from the ECUs that have been memorized as those connected to the CAN movement control bus, the network gateway ECU determines that a malfunction exists.

• If 2 or more DTCs are output during the DTC check, one side of the CAN branch wire may be open (one side of the CANH [CAN branch wire]/CANL [CAN branch wire] of the ECU and/or sensor is open).

INSPECTION PROCEDURE

PROCEDURE

1. PRECAUTION

   Note

   After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work Click here.

   
   

   NEXT

2. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

   
   

   1. Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the CAN main wire and the CAN branch wire.

      CAUTION:

      For vehicles with an SRS system:

      Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.

      Note

      When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.
