      3. With the system in unlock standby mode, hold the front door outer handle assembly and check that all doors are unlocked.
        NOTE:
        • If the electrical key transmitter sub-assembly is inside the detection area, and if the key ID code transmitted from the key matches the one stored in the collation ECM (smart key ECM assembly), the system enters unlock standby mode.
        • If the electrical key transmitter sub-assembly is within 0.2 m (0.66 feet) of the front door outer handle assembly, communication might not be possible.
        • Use the same procedure to inspect the front passenger's door. Check that all doors are unlocked when you touch the passenger's side unlock touch sensor.
      4. Check the unlock response sensitivity. With the system in unlock standby mode, touch the part indicated in the figure and check that the door is unlocked.
        CAUTION: If you touch the sensor too quickly or too slowly, the sensor fails to respond and the door does not unlock.
