STEP 4. Check the wiring harness between joint connector 
(CAN1) C-103 and WCM connector C-29 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 5 and body ground.

OK: 1 k

Ω or more

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

terminal 16 and body ground.

OK: 1 k

Ω or more

Q: Do all the resistances measure 1 k

Ω or more?

YES : Go to Step 5.
NO :  Go to Step 46.
