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 55.

(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 56.

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 57.

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 58.
NO : Repair the wiring harness between joint connector

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