Open wire check (GND line):

Open wire check (GND line)

?1.	Turn the vehicle to the OFF (LOCK) mode.

?2.

Check for continuity between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Millimeter wave radar 10P connector: disconnected
Test point 1	Millimeter wave radar 10P connector (female terminals) No. 1:
Test point 2	Body ground

Is there continuity?


	YES

Go to step 5.


	NO

Repair an open in the GND wire between the millimeter wave radar and ground (G202), or repair poor ground (G202).?

Open wire check (ACC CAN-H line, ACC CAN-L line):

Open wire check (ACC CAN-H line, ACC CAN-L line)

?1.

Disconnect the following connector.

Multipurpose camera unit 20P connector

?2.

Check for continuity between test points 1 and 2.

Test point 1	Multipurpose camera unit 20P connector No. 7
Test point 2	Millimeter wave radar 10P connector (female terminals) No. 3:

Test point 1	Multipurpose camera unit 20P connector No. 18
Test point 2	Millimeter wave radar 10P connector (female terminals) No. 2:

Is there continuity?


	YES

Go to step 6.


	NO

Repair an open in the ACC CAN-H wire or the ACC CAN-L wire between the multipurpose camera unit and the millimeter wave radar.?

Shorted wire check (ACC CAN-H line, ACC CAN-L line):

Shorted wire check (ACC CAN-H line, ACC CAN-L line)

?1.

Check for continuity between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Millimeter wave radar 10P connector: disconnected
