Component Testing

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 navigation antenna coax cable from the navigation antenna within the wiring harness.
  2. Disconnect the navigation antenna 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 greater than 1 ohm resistance at the navigation antenna coax center conductor from end to end.
    • If less than specified value, replace the navigation antenna assembly.
