(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 

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

NO (receiver antenna assembly connector D-14 terminal 
No.5 

− ground.) : Repair the wiring harness between 

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

STEP 10. Replace the receiver antenna assembly, and 
retest the system.
Check that the keyless operation key can be registered.
Q: Is the keyless operation key that cannot be registered 

using scan tool?
YES : Go to Step 11.
NO :  The procedure is complete.

STEP 11. Check the wiring harness between the receiver 
antenna module connector C-08 (terminal Nos. 2, 1, 8, 12) 
and the KOS-ECU connector C-05 (terminal Nos. 11, 12, 32, 
7) for open circuit.
(1) Disconnect reciever anntena module connector C-08 and 

KOS-ECU connector C-05, and check the wiring harness.

(2) Check the wiring harness between reciever anntena 

module connector C-08 (terminal No.2) and KOS-ECU 
connector C-05 (terminal No.11)

OK: Continuity exists (2
