STEP 10. Check the wiring harness between joint 
connector (CAN1) C-103 and satellite radio tuner 
connector C-111 for a short to ground. Measure the 
resistance at joint connector (CAN1) C-103.
(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 3 and body ground.

OK: 1 k

Ω or more

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

terminal 14 and body ground.

OK: 1 k

Ω or more

Q: Do all the resistances measure 1 k

Ω or more?

YES : Go to Step 11.
NO :  Go to Step 30.

STEP 11. Check the wiring harness between joint 
connector (CAN1) C-103 and ETACS-ECU connector C-301 
for a short to ground. Measure the resistance at joint 
connector (CAN1) C-103.
(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 k

Ω or more

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

terminal 19 and body ground.

OK: 1 k

Ω or more

Q: Do all the resistances measure 1 k

Ω or more?

YES : Go to Step 31.
NO :  Repair the wiring harness between joint connector 

(CAN1) C-103 and ETACS-ECU connector C-301.

STEP 12. Check the wiring harness between joint 
connector (CAN1) C-103 and combination meter connector 
C-03 for a short to power supply. Measure the voltage at 
joint connector (CAN1) C-103.

CAUTION

A digital multimeter should be used. For details refer to 

P.54C-7

.

CAUTION

The test wiring harness should be used. For details refer to 

P.54C-7

.

(1) Disconnect joint connector (CAN1), and measure the 

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

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN1) 

terminal 4 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN1) 

terminal 15 and body ground.

OK: 4.7 volts or less

Q: Do all the voltages measure 4.7 volts or less?

YES (vehicles with KOS)  : Go to Step 13.
YES (vehicles with WCM)  : Go to Step 14.
NO (vehicles with KOS and WCM)  : Go to Step 22.
