ASE Electrical and Electronic Systems A6 Practice Exam Prep & Study Guide

When considering what could cause only the console and radio to illuminate when the lights are turned on, a loose connection at G1002 is significant because G1002 is typically a ground point within the vehicle's electrical system. If this connection is loose or intermittent, it might allow certain components, like the console and radio, to receive power, while other lighting components do not operate correctly.

This situation could occur because the affected systems may share a common power source but have varying grounds. If the ground connection at G1002 is unreliable, it may lead to selective illumination, allowing more sensitive or lower-draw components to function while preventing the complete lighting circuit from energizing.

The other options involve issues such as a blown fuse, which would generally affect all components served by that fuse, or faulty connections at specific connectors that could disrupt multiple systems but would likely have broader effects. In contrast, a loose connection specifically at the ground would create the precise situation described where only certain lights operate while others do not.
