Circuit/System Testing: Notes

WARNING: This page is about a different car, the 2016 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • The vehicle may be equipped with sectioned coax. Test each section and replace only the faulty section, not the entire length of coax.
  • The following verification requires the vehicle to be outside with an unobstructed view of the southern sky. Allow 5 minutes after turning the ignition ON for the GPS satellites to acquire vehicle signal.
