STEP 3. Check the wiring harness between joint connector 
(CAN1) C-105 and KOS-ECU connector C-05 for a short to 
ground. Measure the resistance at joint connector (CAN1) 
C-105.
(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 9 and body ground.

OK: 1 kilo ohm or more
