Determination Procedure
CAUTION:
- When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.
- When inspecting the connector, touch it with a paper clip or similar thin pin without directly inserting a tester probe into the terminal.
- Disconnect the negative battery terminal before performing any work that requires handling of connectors.

| No | Go to Step 9. | ||
| 8 | INSPECT PARKING ASSIST UNIT (ULTRASONIC) FOR SHORT BETWEEN CIRCUITS
|
Yes | Repair or replace the wiring harness between the parking assist unit (ultrasonic) and connector C-58 because the wiring harness is shorted between circuits. |
| No | Replace the parking assist unit (ultrasonic) because there is a short between circuits in the parking assist unit (ultrasonic). (See PARKING ASSIST UNIT (ULTRASONIC) REMOVAL/INSTALLATION .) |
||
| 9 | INSPECT BETWEEN REAR SIDE RADAR SENSOR (RH) AND CONNECTOR C-60/C-70 FOR SHORT BETWEEN CIRCUITS
|
Yes | Repair or replace the wiring harness between the connector C-60/C-70 and connector C-58 because the wiring harness is shorted between circuits. |
| No | Go to the next step. | ||
| 10 | INSPECT REAR SIDE RADAR SENSOR (RH) FOR SHORT BETWEEN CIRCUITS
|
Yes | Repair or replace the wiring harness between the rear side radar sensor (RH) and connector C-60/C-70 because the wiring harness is shorted between circuits. |
| No | Replace the rear side radar sensor (RH) because there is a short between circuits in the rear side radar sensor (RH). (See REAR SIDE RADAR SENSOR REMOVAL/INSTALLATION .) |
||
| 11 | INSPECT CAN LINE BETWEEN CONNECTOR C-68 AND CONNECTOR C-69 FOR SHORT BETWEEN CIRCUITS
|
