    1. Disconnect the radio receiver connector.
    2.  
    3. Measure the voltage according to these value(s):

      Tester connection: Antenna body ground.
       
      Condition: Ignition switch on (ignition) and radio switch on.
       
      Specified condition: 10-14 Volts.
       

    4.  

  8.  
  9. If the voltage values do not match, replace radio receiver. If the voltage values match, go to the next step.
  10.  
  11. Check the optional components, (sun-shade film, telephone antenna, etc.) that may decrease reception capacity, are installed.
  12.  
  13. If the optional components are installed correctly, remove optional components and check again. If the optional components are not installed correctly, go to the next step.
  14.  
  15. Check the radio receiver by performing the following:


    1. Remove the antenna plug from the radio receiver.
    2.  
    3. Check for noise.
    4.  
    5. Turn the ignition switch on (ACC) with the radio receiver connector connected.
    6.  
    7. Turn the radio on and put into AM mode.
    8.  
    9. Place a screwdriver, thin wire or other metal object on the radio receiver's antenna jack and check that noise can be heard from the speaker.
    10.  

  16.  
  17. If a noise is not heard from the speaker, replace the radio receiver. If a noise is heard from the speaker, go to the next step.
  18.  
  19. Check the glass antenna by performing the following:
    NOTE
    When cleaning the glass, wipe it in the direction of the wire with a soft dry cloth. Take care not to damage the wire. Do not use detergents or glass cleaners with abrasive ingredients. When measuring voltage, wrap a piece of tin foil around the tip of the negative probe and press the foil against the wire with your finger, as shown in the illustration.
