Component Testing
WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. 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.
- Disconnect the cellular antenna coax connector at the VCIM.
- 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.
- 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.
- If coax cable tests normal, test or replace the VCIM.
