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

2.Remove the rear side radar sensor. (See REAR SIDE RADAR SENSOR REMOVAL/INSTALLATION.)

3.Connect the rear side radar sensor connector.

4.Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)].)

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) and related wiring harnesses.
― If the system does not operate normally even though the inspection items are normal, replace the rear side radar sensor. (See REAR SIDE RADAR SENSOR REMOVAL/INSTALLATION.)
