Is the condition bad in comparison with other vehicles?
Are there any additional installation parts?
(Sun shade film, telephone antenna, etc.)
Check if there is any scratch and breaking of a wire on
the glass antenna and the defogger pattern.
(visual check. tester)
(See page BE-126)
Is the contact of the plug jack of the radio OK?
Does the condition get better by using the outer
antenna (such as pillar antenna)?
Is the contact of the antenna terminal on the glass
surface and the defogger terminal?
Is the continuity of the antenna cord OK?
Check the grounding of the antenna, antenna cord,
choke coil, and noise filter. (See page BE-126)
Does the condition get better by replacing
the choke coil?
Does the condition get better by replacing the
antenna cord?Take a measure for contact. An electric wave environment is bad.
Does the condition get better if
removing them?
Influence of additional installation parts.
Repair. (See Pub. No. RM588E on
