Model code YDRAX4F marks the 2013 Drive Fleet with fuel injection. Its service procedures are in LIT-19616-JC-01.
That book closes at 2013 and opens at 2010, taking in the DC-motor Drive Fleet, the Concierge 4 and 6 in DC and carburetted forms, the DC Adventurer Sport 2+2, and the Drive PTV in base, DC, carburetted and EFI trim.
Injection work is documented with the checks in order: fuel pressure, sensor and injector testing, then engine service with the factory's inspection limits. Clutch and drive line, brakes, steering, suspension and body follow, and the electrical section supplies wiring diagrams rather than generic schematics.
Fitment is confirmed by the YDRAX4F code on the frame plate, and LIT-19616-JC-01 is the number to quote for the manual itself.
