Component Testing

WARNING: This page is about a different car, the 2008 Saturn Outlook, 2008 GMC Acadia, and 2008 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Vehicle may be equipped with sectioned coax. Test each section and replace only the faulty section, not the entire length or coax.
  1. Disconnect the VCIM navigation antenna coax cable from the radio antenna.
  2. Disconnect the navigation antenna coax cable from the VCIM.
  3. Test for infinite resistance between the center conductor of the coax to the metal outer shield.
    • If it does not read infinite, replace the navigation antenna coax cable.
  4. Test for less than 1 ohm resistance at the navigation antenna coax center conductor from end to end.
    • If greater specified value, replace the navigation antenna coax cable.
