Circuit/System Testing

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify there are no obstructions that may block the infra-red port located at the lower edge of the video display screen.
    • If an obstruction exists, remove the obstruction.
  2. Operate the DVD player in play mode. Press multiple buttons on the remote control in succession and verify the remote is inoperative on every button pressed.
  3. Test the remote's functionality with the other screen.
    • If the remote is inoperative, replace the remote batteries.
    • If remote batteries are OK and remote remains inoperative, replace the remote control.
  4. Replace the suspect display screen containing the infra-red port if the remote and batteries are OK.
