Answer: Technician B is correct.
Step-by-step explanation:
When servicing SRS (Supplemental Restraint System) systems, it is important to follow proper safety procedures to avoid any potential hazards. Disconnecting the system fuse and battery is a necessary step in disabling the SRS system to prevent accidental deployment of the airbags during service.
After disconnecting the system fuse and battery, it is recommended to wait for approximately 15 minutes before proceeding with any repairs or maintenance. This waiting period allows the capacitors in the SRS system to discharge fully. Capacitors store electrical energy and can potentially cause an electrical shock if not discharged properly. Waiting for 15 minutes ensures that any residual electrical charge in the system is dissipated, reducing the risk of accidental deployment or electrical hazards.
Using a memory reminder to retain radio presets and other memory functions is not directly related to servicing the SRS system. It is a separate consideration for preserving the settings in the vehicle's electronic systems during a battery disconnect. While it is a good practice to use a memory reminder, it is not directly related to discharging the SRS system capacitors.
Therefore, Technician B is correct in stating that the vehicle should sit for 15 minutes after disconnecting the system fuse and battery to allow for the capacitors to discharge.
I hope this helps :)
