Terminals Of Ecu [11/2024 - ]

WARNING: This page is about a different variant/trim than selected.
NOTE:
  • After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.

    Refer to BEFORE DISCONNECTING BATTERY [11/2023 - ]

  • When disconnecting and reconnecting the auxiliary battery.

    HINT: 

    When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.

    Refer to AUTOMATIC LEARNING CHART [11/2023 - ]

  • 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 (-) auxiliary 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.
