Inspection Procedure 6: The AM/FM Radio Broadcasting Cannot be Received.

CAUTION

Before replacing the multivision display, ensure that the power supply circuit, the ground circuit, and
the communication circuit are normal. (Check that the voltage is 10 V or more.)

.

TECHNICAL DESCRIPTION (COMMENT)

In case of AM/FM radio broadcasting cannot be
received., the roof antenna (antenna rod, antenna
base), antenna fender or multivision display may
have a problem.
NOTE: The radio wave may not be received if the
vehicle is placed in the area which is exposed to a
special electric field. Thus, check that the radio
broadcasting can be received using the radio of
another vehicle before carrying out diagnosis.

.

TROUBLESHOOTING HINTS

• Malfunction of roof antenna (antenna rod,

antenna base)

• Antenna feeder malfunction

• Malfunctions of multivision display

• The wiring harness or connectors may have

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

DIAGNOSIS

STEP 1. Check the state of the antenna rod and
antenna base.

Q: Is the roof antenna assembled?

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

STEP 8. Substitute a known good multivision
display, and check the trouble symptom.

Q: Is the check result normal?

YES :

Replace the multivision display.

NO :

Either repair or replace the antenna rod and
antenna base.

Inspection Procedure 7: GPS signal can not be received.

CAUTION

Whenever the multivision display is replaced,

STEP 2. Check for the vehicle's current position.
Check that the vehicle is parked on a well-ventilated place.
Q: Is the vehicle parked on a well-ventilated place?

YES : Go to Step 3.
NO : Move the vehicle to a well-ventilated area.

STEP 3. Confirming GPS signal reception
(1) Activate the multivision display.
(2) Press the [INFO] button.
(3) Select [Vehicle Position].
(4) Wait for 5 minutes, and then check whether GPS signal can

be received.

Q: Can GPS signal be received?

YES : The diagnosis is complete. (There is no failure)
NO : Go to Step 4.

STEP 4. Substitute a known good multivision display, and
check the trouble symptom.
(1) Temporarily replace the multivision display.
(2) Activate the multivision display.
(3) Press the [INFO] button.
(4) Select [Vehicle Position].
(5) Check if the GPS signals are being received after 5 minutes

have elapsed.
