Component Testing

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: The vehicle may be equipped with sectioned coax. Test each section and replace only the faulty section, not the entire length of coax.
  1. Disconnect the cellular antenna coax connector at the VCIM.
  2. Test for infinite resistance between the center conductor and the outer metal shield of the cellular antenna coax cable.
    • If meter does not read infinite, replace the cellular antenna coax cable.
  3. Test for less than 1 ohm of resistance at the cellular antenna coax connector from end to end.
    • If greater than specified value, replace the cellular antenna coax cable.
  4. If coax cable tests normal, test or replace the VCIM.
