I am attaching the procedure from the manual below on the testing information for this code.
Plus I am attaching the process below to replace this sensor. Yes you need to discharge the system just to be sure there are no accidental deployment. There is a process for this as well and I attached it below along with the other info.
Let us know if there are questions. Thanks
