assembly connector D-14 (terminal No.8) and and ground

OK: No continuity

(4) Check the wiring harness between reciever anntena

assembly connector D-14 (terminal No.12) and and ground

OK: No continuity

(5) Check the wiring harness between reciever anntena

assembly connector D-14 (terminal No.3) and ground

OK: No continuity

(6) Check the wiring harness between reciever anntena

assembly connector D-14 (terminal No.5) and ground

OK: No continuity

Q: Is the wiring harness between receiver antenna

assembly connector D-14 (terminal Nos.1, 8, 12, 3, 5)
and the ground in good condition?
YES : Go to Step 10.
NO (receiver antenna assembly connector D-14 terminal
No.1

− ground.) : Repair the wiring harness between

receiver antenna assembly connector D-14 (terminal
No.1) and the KOS-ECU connector C-05 (terminal
No.12).

NO (receiver antenna assembly connector D-14 terminal
No.8

− ground.) : Repair the wiring harness between

receiver antenna assembly connector D-14 (terminal
No.8) and the ground.

NO (receiver antenna assembly connector D-14 terminal
No.12

− ground.) : Repair the wiring harness between

receiver antenna assembly connector D-14 (terminal
No.12) and the ground.

NO (receiver antenna assembly connector D-14 terminal
No.3

− ground.) : Repair the wiring harness between
