1.Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)].)
2.Remove the front side radar sensor. (See FRONT SIDE RADAR SENSOR REMOVAL/INSTALLATION.)
3.Connect the front 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 front side radar sensor. (See FRONT SIDE RADAR SENSOR REMOVAL/INSTALLATION.)
