Terminals Of Ecu [06/2021 - 09/2022]

WARNING: This page is about a different variant/trim than selected.
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.

    Refer to INITIALIZATION [04/2020 - 09/2022]

  • Before measuring the resistance of the CAN bus, turn the power 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 (-) auxiliary battery terminal and leave the vehicle for 10 minutes or more before measuring the resistance.
  • This information describes the standard values for all CAN related components.
