TECHNICAL DESCRIPTION (COMMENT)

• The power supply to the hands free module is 

provided by the fusible link No.36.

• The ACC signal is received hands free module 

C-141 terminal (terminal 15) from radio and CD 
player connector C-14 terminal (terminal 17). 
<Vehicles with radio and CD player>

• The ACC signal is received hands free module 

C-141 terminal (terminal 15) from multivision dis-
play connector C-06 terminal (terminal 82).<Vehi-
cles with MMCS>

.

TROUBLESHOOTING HINTS

• The wiring harness or connectors may have 

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

• The hands free module may be defective

• The radio and CD player may be defective. 

<Vehicles with radio and CD player>

• The multivision display may be defective. <Vehi-

cles with MMCS>

DIAGNOSIS

Required Special Tools:

• MB991223: Harness Set

• MB992006: Extra Fine Probe

STEP 1. Check hands free module connector C-141 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: IS hands free module connector C-141 in good 

condition?
YES : 
Go to Step 2.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

.

STEP 2. Check the ground circuit to the hands free 
module. Measure the resistance at hands free module 
connector C-141.
(1) Disconnect hands free module connector C-141, and 

measure at the wiring harness side.

(2) Measure resistance between terminal 17 and ground.

OK: The resistance should be 2 ohm or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 4.
NO :  Go to Step 3.

STEP 3. Check the wiring harness between hands free 
module connector C-141 (terminal 17) and ground.

• Check the body ground wires for open circuit.

Q: Is the wiring harness between hands free module 

connector C-141 (terminal 17) and ground 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

).

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.

STEP 4. 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) Measure the voltage between terminal 1 and ground.

OK: The voltage should measure approximately 12 
volts (battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : 
Go to Step 6.
NO :  Go to Step 5.
