WARNING: This page is about a different car, the 2007 Pontiac Torrent and 2007 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
- Using a DMM to measure the resistance of the navigation antenna coax from the center conductor to the outer shield while the antenna is still connected will damage the navigation antenna.
- 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 navigation antenna coax connector from the navigation antenna.
- Test for infinite resistance between the center conductor of the coax to the metal outer shield.
- If not specified value, replace the navigation antenna coax.
- Test for less than 1 ohm resistance of navigation antenna coax connector from end to end.
- If not specified value, replace the navigation antenna coax.
- If cellular antenna coax tests normal, test or replace the VCIM.
