STEP 18. Check the wiring harness between joint 
connector (CAN1) C-103 and radio and CD player or radio 
and CD changer connector C-16 for a short to power 
supply. Measure the voltage at joint connector (CAN1) 
C-103.

CAUTION

A digital multimeter 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 10 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN1) 

terminal 23 and body ground.

OK: 4.7 volts or less

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

YES (vehicles without satellite radio)  : Go to Step 21.
YES (vehicles with satellite radio)  : Go to Step 20.
NO  :  Go to Step 28.
