Antenna, Radio: Testing and Inspection

Inspection

Glass Antenna Test
1. Wrap aluminum foil (A) around the tip of the tester probe (B) as shown.




2. Touch one tester probe to the glass antenna terminal (A) and move the other tester probe along the antenna wires to check that continuity exists.






Glass Antenna Circuit Inspection
1. Remove the right side rear quarter trim.
Then disconnect the antenna feeder cable(A) from the glass antenna amp.




2. Turn the radio ON.
Measure the voltage between terminal 2 of the harness side feeder cable(A) and body ground(B).

OK :approximately 12V (ACC+)




3. Disconnect the 2P connector of radio wiring from the glass antenna amp.
4. Check for continuity between terminals of harness side connector(B) and antenna grid terminals(A).




5. Check the grid lines for continuity.
6. When a poor radio reception is not repaired through the above inspection methods, replace the amp.
If the radio reception is still poor, check the radio cable for short and radio head unit for failure.
