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.

Yes	Repair or replace the wiring harness between the parking assist unit (optical)/360° view monitoring camera unit and connector C-47 because the wiring harness is shorted to ground.
5		No	Replace the parking assist unit (optical)/360° view monitoring camera unit because there is a short to ground in the parking assist unit (optical)/360° view monitoring camera unit. (See 360°VIEW MONITOR CONTROL MODULE REMOVAL/INSTALLATION (US) .) (See PARKING ASSIST UNIT (OPTICAL) REMOVAL/INSTALLATION (US) .)
6	INSPECT CAN LINE IN JB No. 1 FOR SHORT TO GROUND Disconnect the connector C-46. Connect the connector C-47. Inspect for continuity at the following terminals: Between body control module (BCM) terminal 2E and body ground Between body control module (BCM) terminal 2G and body ground Is there continuity?	Yes	Replace the JB No. 1 because there is a short to ground in the JB No. 1.
6		No	Go to the next step.
7	INSPECT FOR SHORT TO GROUND BETWEEN CONNECTOR C-13 AND CONNECTOR C-46 Disconnect the connector C-13. Connect the connector C-46. Inspect for continuity at the following terminals: Between body control module (BCM) terminal 2E and body ground Between body control module (BCM) terminal 2G and body ground Is there continuity?	Yes	Repair or replace the wiring harness between the connector C-13 and connector C-46 because the wiring harness is shorted to ground.
7		No	Go to the next step.
8	INSPECT FOR SHORT TO GROUND BETWEEN CONNECTOR C-39 AND CONNECTOR C-13 Disconnect the connector C-39. Connect the connector C-13. Inspect for continuity at the following terminals: Between body control module (BCM) terminal 2E and body ground Between body control module (BCM) terminal 2G and body ground Is there continuity?	Yes	Repair or replace the wiring harness between the connector C-39 and connector C-13 because the wiring harness is shorted to ground.
8		No	Go to the next step.
9	INSPECT FOR SHORT TO GROUND BETWEEN DRIVER MONITORING CAMERA UNIT AND CONNECTOR C-39 Inspect for continuity at the following terminals: Between driver monitoring camera unit terminal 1F and body ground Between driver monitoring camera unit terminal 1E and body ground Is there continuity?	Yes	Go to the next step.
9		No	Go to Step 11.
10	INSPECT CAN LINE IN DRIVER MONITORING CAMERA UNIT FOR SHORT TO GROUND Disconnect the driver monitoring camera unit connector. Inspect for continuity at the following terminals: Between driver monitoring camera unit terminal 1F (wiring harness side) and body ground Between driver monitoring camera unit terminal 1E (wiring harness side) and body ground Is there continuity?	Yes	Repair or replace the wiring harness between the driver monitoring camera unit and connector C-39 because the wiring harness is shorted to ground.
10		No	Replace the driver monitoring camera unit because there is a short to ground in the driver monitoring camera unit. (See DRIVER MONITORING CAMERA UNIT REMOVAL/INSTALLATION (US) .)
