Circuit/System Verification

NOTE: Verify that the iPod® is in good working order and visually inspect the iPod® connector cavity for any signs of damage before performing this diagnostic. Verify the most up to date software has been downloaded from http://www.apple.com/support/ipod/ to the iPod® before performing this diagnostic.
  1. Tune to a strong AM or FM station and verify each speaker is producing clear and even sound, with no distortion.
  2. Ignition ON, Observe the PAL red LED lamp. Verify the red LED lamp is illuminated.
  3. Set the radio to the iPod® interface menu and attempt to operate audio from the iPod®.
  4. Inspect the interface harness at the connection to the iPod® and verify that audio quality from the iPod® is not changed when the harness is bent in multiple directions.
    • If the audio changes quality or drops out, inspect the iPod® connector cavity or interface cable for damage. If no damage found, replace the iPod® interface cable.
