The Quietech EFI version of the four-passenger Concierge for 2024 carries code DR2A24_PTV-4. Its factory manual is Yamaha LIT-19616-A3-03.
That volume was written for the 2024 and 2025 injected Drive2 cars, seven models in all, including the Concierge 6 Quietech EFI, the Adventurer Super Hauler EFI cars, the EFI Quietech IRS PTV and the EFI fleet models on both chassis.
Quietech work centres on the engine and injection system, and the book treats both properly: fault code diagnosis, sensor and actuator readings, fuel pressure and pump testing, injector and throttle body service, valve clearance and engine assembly with torque figures. The clutch, belt and transaxle follow, then brakes and park brake, steering, suspension, wheels, the passenger seat structure and the body, with wiring diagrams last.
Verify DR2A24_PTV-4 on the plate. The PowerTech AC Concierge 4 of the same year is covered by a different book.
