STEP 9. Check the wiring harness between joint connector 
(CAN1) C-105 and radio and CD player or CD changer 
connector C-107 for a short to ground. Measure the 
resistance at joint connector (CAN1) C-105.
(1) Disconnect joint connector (CAN1), and measure the 

resistance at the wiring harness side of joint connector 
(CAN1).

(2) Measure the resistance between joint connector (CAN1) 

terminal 5 and body ground.

OK: 1 kΩ or more

(3) Measure the resistance between joint connector (CAN1) 

terminal 16 and body ground.

OK: 1 kΩ or more

Q: Do all the resistances measure 1 kΩ or more?

YES <vehicles without satellite radio> : Go to Step 12.
YES <vehicles with satellite radio> : Go to Step 11.
NO  :  Go to Step 31.

STEP 10. Check the wiring harness between joint 
connector (CAN1) C-105 and CAN box unit connector C-15 
for a short to ground. Measure the resistance at joint 
connector (CAN1) C-105.
(1) Disconnect joint connector (CAN1), and measure the 

resistance at the wiring harness side of joint connector 
(CAN1).

(2) Measure the resistance between joint connector (CAN1) 

terminal 5 and body ground.

OK: 1 kΩ or more

(3) Measure the resistance between joint connector (CAN1) 

terminal 16 and body ground.

OK: 1 kΩ or more

Q: Do all the resistances measure 1 kΩ or more?

YES (vehicles without satellite radio) : Go to Step 12.
YES (vehicles with satellite radio) : Go to Step 11.
NO  :  Go to Step 32.

STEP 11. Check the wiring harness between joint 
connector (CAN1) C-105 and satellite radio tuner 
connector C-18 for a short to ground. Measure the 
resistance at joint connector (CAN1) C-105.
(1) Disconnect joint connector (CAN1), and measure the 

resistance at the wiring harness side of joint connector 
(CAN1).

(2) Measure the resistance between joint connector (CAN1) 

terminal 2 and body ground.

OK: 1 kΩ or more

(3) Measure the resistance between joint connector (CAN1) 

terminal 13 and body ground.

OK: 1 kΩ or more

Q: Do all the resistances measure 1 kΩ or more?

YES : Go to Step 12.
NO :  Go to Step 33.

STEP 12. Check the wiring harness between joint 
connector (CAN1) C-105 and ETACS-ECU connector C-301 
for a short to ground. Measure the resistance at joint 
connector (CAN1) C-105.
(1) Disconnect joint connector (CAN1) and ETACS-ECU 

connector C-301, and measure the resistance at the wiring 
harness side of joint connector (CAN1).

(2) Measure the resistance between joint connector (CAN1) 

terminal 6 and body ground.

OK: 1 kΩ or more

(3) Measure the resistance between joint connector (CAN1) 

terminal 19 and body ground.

OK: 1 kΩ or more

Q: Do all the resistances measure 1 kΩ or more?

YES : Go to Step 34.
NO :  Repair the wiring harness between joint connector 

(CAN1) C-105 and ETACS-ECU connector C-301.
