Service bulletin TT474
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
TECHNICAL TIP BULLETIN TT474: LIVEWIRE - POWER DISCONNECT UPDATE. PURPOSE: Revision. An update to the power disconnect procedure has been made. The wait time of 2 minutes has been increased to 5 minutes to allow for proper system shut down on Electric LiveWire™ (ELW). This Technical Tip reinforces the ELW power disconnect procedure found in the owner's and service manuals. The power disconnect procedure must be followed whenever removing 12 V power. Disconnecting OBC [307-2] and not waiting 5 minutes after placing the OFF/RUN switch in OFF position can cause electrical issues including, but not limited to: • Diagnostic Trouble Codes (DTCs) generated. • Communication errors between the modules (OBC, Electric Vehicle Power-Train (EVPT), Rechargeable Energy Storage System (RESS)) that may be unrecoverable requiring replacement of the part.
