Before servicing the supplemental restraint system, what should a technician do as a safety precaution?

Before servicing the supplemental restraint system, disarming the system is essential for safety. This precaution ensures that the airbag and other related components do not inadvertently deploy while the technician is working on the vehicle. Airbag systems can be sensitive to electrical signals, and if the system is left armed, it poses a significant risk of accidental deployment, which could result in injury to the technician.

Disarming the system typically involves disconnecting the battery and following specific manufacturer instructions to ensure that the airbag is completely disabled before any repair or maintenance work is performed. This step protects both the technician and the vehicle's safety systems during servicing.

The other choices, such as cutting wires or probing with a test light, are not standard safety practices and could create additional risks by disturbing the integrity of the system or leading to accidental deployment. Removing the airbag is not necessary before servicing and can be dangerous without first disarming the system.
