2009 Yamaha DRIVE CONCIERGE 4 (48V - DC MOTOR) Service and Repair M...
Service information for the 2009 Drive Concierge 4 with the 48-volt DC motor, code YDRESVS_PTV4, is published as LIT-19616-29-08.
Yamaha listed that volume for the 2007 and 2009 model years and used it for a group of early Drive cars: the YDRA carburetted Drive Fleet and Drive PTV, the YDRE DC-motor Fleet and PTV, the YTF1 Adventurer One, the carburetted Concierge 4, and the Concierge 6 in both DC and carburetted forms.
The four-seat Concierge shares its chassis and drive with those cars, so the repair text applies directly. Motor and battery work, brakes, steering, suspension, seating and body are all covered, and the wiring diagrams let an electrical fault be traced instead of guessed.
Match YDRESVS_PTV4 to the data plate and keep LIT-19616-29-08 for reference.
