STEP 1. Check the wiring harness between joint connector 
(CAN2) C-04 and ETACS-ECU connector C-301 for a short 
to power supply. Measure the voltage at joint connector 
(CAN2) C-04.
(1) Disconnect joint connector (CAN2), and measure the 

voltage at the wiring harness side of joint connector 
(CAN2).

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN2) 

terminal 6 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN2) 

terminal 19 and body ground.

OK: 4.7 volts or less

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

YES <vehicles with ASC> : Go to Step 2.
YES <vehicles without ASC (FWD)> : Go to Step 5.
YES <vehicles without ASC (Electric controlled AWD)> : 

Go to Step 3.

NO  :  Go to Step 11.

STEP 2. Check the wiring harness between joint connector 
(CAN2) C-04 and steering wheel sensor connector C-209 
for a short to power supply. Measure the voltage at joint 
connector (CAN2) C-04.

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

.

(1) Disconnect joint connector (CAN2), and measure the 

voltage at the wiring harness side of joint connector 
(CAN2).

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN2) 

terminal 4 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN2) 

terminal 15 and body ground.

OK: 4.7 volts or less

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

YES <FWD> : Go to Step 5.
YES <Electric controlled AWD> : Go to Step 3.
YES <S-AWC> : Go to Step 4.
NO  :  Go to Step 8.

STEP 3. Check the wiring harness between joint connector 
(CAN2) C-04 and AWD-ECU connector C-128 for a short to 
power supply. Measure the voltage at joint connector 
(CAN2) C-04.
(1) Disconnect joint connector (CAN2), and measure the 

voltage at the wiring harness side of joint connector 
(CAN2).

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN2) 

terminal 5 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN2) 

terminal 16 and body ground.

OK: 4.7 volts or less

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

YES : Go to Step 5.
NO :  Go to Step 9.
