1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the following parts:

(1)  Set plate (See SET PLATE REMOVAL/INSTALLATION.)

(2)  Fresh-air duct installation bolt (See INTAKE AIR GUIDE REMOVAL/INSTALLATION.)

(3)  Front bumper (See FRONT BUMPER REMOVAL/INSTALLATION.)

3.  Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

4.  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.)
