Circuit/System Verification

WARNING: This page is about a different car, the 2010 Chevrolet HHR. However, it is still accessible from the selected car via links, so may be relevant.
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.
    • If any speaker is not producing sound or the sound produced is distorted, refer to Speaker Malfunction .
  2. Ignition ON, Observe the PAL red LED lamp. Verify the red LED lamp is illuminated.
    • If the PAL red LED is not illuminated, go to Circuit/System Testing.
  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.
