CAN COMMUNICATION SYSTEM TERMINALS OF ECU

Note


  • After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work Click here.

  • Turn the power switch off before measuring the resistances between CAN main bus lines and between CAN branch lines.

  • Turn the power switch off before inspecting CAN bus lines for a ground short.

  • After the power switch is turned off, check that the key reminder warning system and light reminder warning system are not operating.

  • Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the power switch, any other switches or the doors. If any doors need to be opened in order to check connectors, open the doors and leave them open.

  • This section describes the standard values for all CAN related components.

Tech Tips


  • Operating the power switch, any other switches or a door triggers related ECU and sensor communication on the CAN. This communication will cause the resistance value to change.

  • Even after DTCs are cleared, if a DTC is stored again after driving the vehicle for a while, the malfunction may be occurring due to vibration of the vehicle. In such a case, wiggling the ECUs or wire harness while performing the inspection below may help determine the cause of the malfunction.


  1. CAN NO. 1 JUNCTION CONNECTOR (for LHD)


    1. Check the CAN No. 1 junction connector (Engine room main wire side).

      Tech Tips

      The following tables contain information about the items and buses connected via junction connectors. The junction connector may be used for multiple separate buses. In this case, the name of the bus will be shown below the name of the item that terminals are connected to. The bus name will be shown in brackets (example: (for Power management bus)).
