Terminals Of Ecu [12/2019 - 10/2022]

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

    Refer to INITIALIZATION [12/2019 - 09/2020] , or refer to INITIALIZATION [09/2020 - 10/2021] , or refer to INITIALIZATION [10/2021 - 10/2022]

  • Before measuring the resistance of the CAN bus, turn the ignition switch off and leave the vehicle for 1 minute or more without operating the key or any switches, or opening or closing the doors. After that, disconnect the cable from the negative (-) battery terminal and leave the vehicle for 10 minutes or more before measuring the resistance.
  • This section describes the standard values for all CAN related components.
