1.  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].)

2.  Remove the front bumper. (See FRONT BUMPER REMOVAL/INSTALLATION.)

3.  Remove the radar unit. (See RADAR UNIT REMOVAL/INSTALLATION.)

4.  Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].)

5.  Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).

•  If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s).
―  If the system does not operate normally even though the inspection items are normal, replace the radar unit. (See RADAR UNIT REMOVAL/INSTALLATION.)
