REAR SIDE RADAR SENSOR INSPECTION

id152000020900

1. Disconnect the negative lead-acid battery terminal. (See NEGATIVE LEAD-ACID BATTERY TERMINAL DISCONNECTION/CONNECTION.)

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 lead-acid battery terminal. (See NEGATIVE LEAD-ACID BATTERY TERMINAL DISCONNECTION/CONNECTION.)

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.)
