STEP 13. 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.

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 (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 3 and body ground.

OK: 4.7 V or less

(4) 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 14.
YES (vehicles with WCM) : Go to Step 15.
NO (vehicles with KOS and WCM) : Go to Step 24.
