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-

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.
