STEP 5. Check the wiring harness between hands free 
module connector C-141 (terminal 1) and fusible link (36).

• Check the power supply line for open circuit and short cir-

cuit.

NOTE: Also check ETACS-ECU connector C-307, C-317 for 
loose, corroded, or damaged terminals, or terminals pushed 
back in the connector. If ETACS-ECU connector C-307, C-317 
is damaged, repair or replace the connector as described in 
GROUP 00E, Harness Connector Inspection  

P.00E-2

.

Q: Is the wiring harness between hands free module 

connector C-141 (terminal 1) and fusible link (36) in 
good condition?
YES : 
The trouble can be an intermittent malfunction (Refer 

to GROUP 00, How to use 
Troubleshooting/inspection Service Points, How to 
Cope with Intermittent Malfunction 

P.00-15

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary.

STEP 6. Check the power supply circuit to the hands free 
module. Measure the voltage at hands free module 
connector C-141.
(1) Disconnect hands free module connector C-141, and 

measure the voltage available at the wiring harness side of 
the connector.

(2) Turn the ignition switch to "ACC" position.
(3) Measure the voltage between terminal 15 and ground.

OK: 1 voltage or less.

Q: Is the measured voltage 1 voltage or less?

YES : Replace the hands free module.
NO :  Go to Step 7.

STEP 7. Check radio and CD player connector C-14 
<Vehicles with radio and CD player> or multivision display 
connector C-06 <Vehicles with MMCS> for loose, corroded 
or damaged terminals, or terminals pushed back in the 
connector.
Q: Is radio and CD player connector C-14 <Vehicles with 

radio and CD player> or multivision display connector 
C-06 <Vehicles with MMCS> in good condition?
YES : 
Go to Step 8.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection

STEP 8. Check the wiring harness between hands free 
module connector C-141 terminal (terminal 15) and radio 
and CD player connector C-14 terminal(terminal 17) 
<vehicles with radio and CD player> or multivision display 
connector C-06 terminal (terminal 82) <vehicles with 
MMCS>.

• Check the signal line for open circuit and short circuit.

NOTE: Also check intermediate connector C-15 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector C-15 is damaged, repair or 
replace the connector as described in GROUP 00E, Harness 
Connector Inspection 

P.00E-2

. <Vehicles with MMCS>

Q: Is the check result normal?

YES : Replace the radio and CD player or multivision 

display

NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary.

INSPECTION PROCEDURE 2: The USB adapter data cannot be replayed. <Vehicles with radio and CD 
player>

CAUTION

Before replacing the hands free module, ensure that the power supply circuit, the ground circuit and 
the communication circuit are normal.

TECHNICAL DESCRIPTION (COMMENT)

If the sound replay is impossible with the USB mode, 
the USB adapter, USB cable, hands free module, or 
radio and CD player may be defective, or a commu-
nication error between the radio and CD player and 
hands free module may have occurred.

NOTE: Before troubleshooting, check that the music 
file (the customer tried to replay) can be replayed. 

.

TROUBLESHOOTING HINTS

• The radio and CD player may be defective.
