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.

.

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?
