Inspection

Glass Antenna Test
  1. Wrap aluminum foil (A) around the tip of the tester probe (B), and move the probe along the grid line to check whether it is open.
  2. Place one end of the tester probe on the glass antenna connector (A), and move the other end along the antenna wire to check continuity.
Glass Antenna Repair
To make an effective repair, the broken section must be no longer than one inch.
  1. Lightly rub the area around the broken section (A) with fine steel wool, then wipe with alcohol. Attach masking tape as shown below.
  2. Mix conductive paint with thinner and apply the mixture three times at 15-minute intervals.
  3. Before applying power, remove the masking tape. For a finished surface, remove excess paint with a knife after the paint has dried (approx. 1 day).
    After completing the repair, wipe the glass with a dry soft cloth or wipe the grid line with a slightly damp cloth.
  4. Check the continuity of the repaired wire.
  5. Remove the right glass antenna from the rear quarter trim, then disconnect the power wire from the amplifier.
  6. Turn on the radio. Measure the voltage between terminal 2 of the power cable on the harness side (A) and body ground (B).

    OK: Approximately 12 V (ACC+)

  7. Using the tester, measure the resistance of the AM wiring between 1 and 2.
    A. AM / FM Antenna Grid Terminal
    B. Body ground
  8. Using a tester, measure the resistance of the FM wiring between A and B.
    A. FM2 antenna array terminal
    B. Body ground
  9. Check the grid lines for continuity.
  10. If radio reception is poor even after checking the circuit, replace the glass antenna amplifier. If reception quality does not improve, inspect the radio cable and audio unit.
  11. Check continuity between the center terminals of the antenna cable.
  12. Check continuity between the outer terminals of the antenna cable. There should be continuity.
  13. If there is no continuity, replace the antenna cable.
  14. Check continuity between the center terminal (A) of the antenna cable and the glass antenna terminal (B). There should be continuity.
  15. If there is no continuity, replace the antenna amplifier.
  16. Check continuity between the center terminal (A) and the outer terminal (B) of the antenna cable. There should be no continuity.
  17. If there is continuity, replace the antenna cable.

Removal

  1. Disconnect the negative (-) battery terminal.
  2. Remove the roof headlining. (Refer to Body - "Roof Headlining Assembly")
  3. Remove the roof antenna (A) after loosening the nut (B).

Installation

  1. Connect the roof antenna connectors.
  2. Install the rear roof garnish.
    • Make sure the cables and connectors are connected correctly.
    • Check the audio system.
