    After all doors (including trunk lid or back door) are closed, if a door (including trunk lid or back door) is opened before battery terminals are disconnected, start over from Step 1.

    • For vehicles with the 2-batteries, be sure to connect the main battery and the sub battery before turning ON the ignition switch.
      NOTE: If the ignition switch is turned ON with any one of the terminals of main battery and sub battery disconnected, then DTC may be detected.
    • After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
