Work Procedure

  1. Check that EVSE is not connected.
    NOTE:

    If EVSE is connected, the air conditioning system may be automatically activated by the timer A/C function.

  2. Turn the power switch OFF → ON → OFF. Get out of the vehicle. Close all doors (including back door).
  3. Check that the charge status indicator lamp does not blink and wait for 5 minutes or more.
    NOTE:

    If the battery is removed within 5 minutes after the power switch is turned OFF, plural DTCs may be detected.

  4. Remove 12V battery terminal within 60 minutes after turning the power switch OFF → ON → OFF.
    CAUTION:
    • After all doors (including back door) are closed, if a door (including back door) is opened before battery terminals are disconnected, start over from Step 1.
    • After turning the power switch OFF, if "Remote A/C" is activated by user operation, stop the air conditioner and start over from Step 1.
    NOTE:

    Once the power switch is turned ON → OFF, the 12V battery automatic charge control does not start for approximately 1 hour.

    • For vehicles with the 2 - batteries, be sure to connect the main battery and the sub battery before turning ON the power switch.
      NOTE:
