Precautions for Removing of Battery Terminal

  • When removing the 12V battery terminal, turn OFF the ignition switch and wait at least 30 seconds.
    NOTE: ECU may be active for several tens of seconds after the ignition switch is turned OFF. If the battery terminal is removed before ECU stops, then a DTC detection error or ECU data corruption may occur.
  • 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.
    NOTE: The removal of 12V battery may cause a DTC detection error.
