STEP 4. Check the wiring harness between joint connector 
(CAN3) C-127 and ASC-ECU connector A-05 for a short to 
ground. Measure the resistance at joint connector (CAN3) 
C-127.

CAUTION

Disconnect the negative battery terminal. For details refer 
to 

P.54C-7

.

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 (CAN3), and measure the 

resistance at the wiring harness side of joint connector 
(CAN3).

(2) Measure the resistance between joint connector (CAN3) 

terminal 6 and body ground.

OK: 1 kΩ or more

(3) Measure the resistance between joint connector (CAN3) 

terminal 19 and body ground.

OK: 1 kΩ or more

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

YES <M/T> : Go to Step 5.
YES <TC-SST> : Go to Step 6.
NO  :  Go to Step 13.

STEP 5. Check the wiring harness between joint connector 
(CAN3) C-127 and ECM connector B-10 <M/T> for a short to 
ground. Measure the resistance at joint connector (CAN3) 
C-127.

CAUTION

Disconnect the negative battery terminal. For details refer 
to 

P.54C-7

.

.

(1) Disconnect joint connector (CAN3), and measure the 

resistance at the wiring harness side of joint connector 
(CAN3).

(2) Measure the resistance between joint connector (CAN3) 

terminal 4 and body ground.

OK: 1 kΩ or more

(3) Measure the resistance between joint connector (CAN3) 

terminal 15 and body ground.

OK: 1 kΩ or more

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

YES : Check intermediate connector C-131, and repair if 

necessary. If the intermediate connector is in good 
condition, repair the wiring harness between joint 
connector (CAN2) C-104 and joint connector (CAN3) 
C-127.

NO :  Go to Step 14.
