The six-seat Drive Concierge of 2009 with the 48-volt DC motor is coded YDRESVL_PTV6, and its service book is LIT-19616-29-08.
Yamaha assigned that volume to the 2007 and 2009 model years and used it for the early Drive group: the YDRA carburetted Fleet and PTV, the YDRE DC-motor Fleet and PTV, the YTF1 Adventurer One, the Concierge 4 in DC and carburetted forms, and the carburetted Concierge 6.
Longer-wheelbase cars carry extra seating and a stretched frame, and the body and chassis sections account for that while the drive chapters are shared with the shorter models. Motor, controller and battery checks, brake and steering work, suspension, and wiring diagrams are all included with their specified figures.
Confirm YDRESVL_PTV6 on the data plate; the number is LIT-19616-29-08.
