To disable the airbag system, Technician A states that disconnecting the negative battery cable may be necessary. What does Technician B say?

The correct response highlights the importance of safety when working with airbag systems. Using a self-powered test light to verify the condition of airbag components is a recognized practice. This method allows technicians to test the circuits without activating the airbag system, effectively ensuring that the airbag is not deployed inadvertently while diagnostics or repairs are being performed.

In the context of airbag safety, it is indeed critical to properly assess components before engaging in work that might interact with the system. Self-powered test lights can reveal circuit continuity or faults without posing a danger that might arise from directly interfacing with the airbag system's wiring or components.

This choice signifies adherence to safety protocols that should always be followed when dealing with automotive safety features. It stands in contrast to other options, the relevance of which may be less significant or safe in the context of airbag maintenance. For instance, while the negative battery cable is often disconnected as a standard precaution, simply ensuring that a test light is employed appropriately provides an added layer of caution during the repair process.
