Technician A says an ohmmeter can be used to measure the resistance of the airbag inflator module. Technician B says a test light should be used to check for voltage at the airbag inflator module. Who is correct?

Using an ohmmeter to measure resistance on the airbag inflator module is inappropriate because airbag systems contain components that can be sensitive to resistance measurements. These components are designed to deploy under specific electrical conditions, and an ohmmeter might inadvertently apply a voltage or cause an unwanted current flow, potentially damaging the module or creating a safety hazard.

Additionally, using a test light to check for voltage in the airbag system is also not advisable. Test lights can draw too much current and may inadvertently trigger an airbag deployment. Furthermore, airbag systems require specialized diagnostic tools that can safely interact with these modules while monitoring their operational status without risking deployment or damage.

Both technicians provide methods that are not suitable for checking the airbag inflator module; therefore, neither technician's statement is correct. Proper safety protocols and diagnostic procedures must always be observed when working with airbag and restraint systems.
