Question

Quizplus · Accepted Answer

Neither technician is correct. A self-powered test light may be used to diagnose basic electrical circuits but not air bag circuits, which require specialized diagnostic tools. Similarly, a conventional 12 v test light should not be used to diagnose automotive computer circuits, as it can cause damage to sensitive electronic components. These circuits require specialized diagnostic tools such as a digital multimeter or an oscilloscope.
