## NHTSA's summary

CARB Label Procedure Update The repair procedure removes the aftermarket change request, adds GHG label inspection, and directs dealers to open a TCS365 case to order new labels. Warranty codes for inspection and label replacement have been updated. Certain Battery Electric Vehicles that are subject to California Air Resources Board \(CARB\) regulations have GHG labels that are missing the CARB Enhanced EV and FCEV Statement.
