STEP 13. Check the wiring harness between ETACS-ECU 
connector C-301 and body ground for a short to power 
supply. Measure the voltage at ETACS-ECU connector 
C-301.
(1) Disconnect ETACS-ECU connector C-301, and measure 

the voltage at the wiring harness side of ETACS-ECU 
connector.

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between ETACS-ECU connector 

terminal 6 and body ground.

OK: 4.7 V or less

(4) Measure the voltage between ETACS-ECU connector 

terminal 7 and body ground.

OK: 4.7 V or less

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

YES : Go to Step 25.
NO :  Go to Step 14.

STEP 14. Check the wiring harness between joint 
connector (CAN1) C-105 and combination meter connector 
C-04 for a short to power supply. Measure the voltage at 
joint connector (CAN1) C-105.
(1) Disconnect joint connector (CAN1), and measure the 

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

(2) Connect the negative battery terminal.
(3) Turn the ignition switch to the ON position.
(4) Measure the voltage between joint connector (CAN1) 

terminal 3 and body ground.

OK: 4.7 V or less

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

terminal 14 and body ground.

OK: 4.7 V or less

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

YES (vehicles with KOS) : Go to Step 15.
YES (vehicles with WCM) : Go to Step 16.
NO (vehicles with KOS and WCM) : Go to Step 48.

STEP 15. Check the wiring harness between joint 
connector (CAN1) C-105 and KOS-ECU connector C-05 for 
a short to power supply. Measure the voltage at joint 
connector (CAN1) C-105.
(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 9 and body ground.

OK: 4.7 V or less

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

terminal 22 and body ground.

OK: 4.7 V or less

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

YES : Go to Step 17.
NO :  Go to Step 49.

STEP 16. Check the wiring harness between joint 
connector (CAN1) C-105 and WCM connector C-07 for a 
short to power supply. Measure the voltage at joint 
connector (CAN1) C-105.
(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 7 and body ground.

OK: 4.7 V or less

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

terminal 20 and body ground.

OK: 4.7 V or less

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

YES : Go to Step 17.
NO :  Go to Step 50.
