2024 Yamaha UMAX BISTRO EFI Service and Repair Manual

Beverage-body UMAX cars for 2024 are coded YUM2A24_BEVER, and they sit inside LIT-19616-A3-12 with seven other 2024 UMAX configurations.

Yamaha's approach with this volume is to write the common work once. Chassis, brakes, steering, suspension, wheels and the shared body hardware apply across the group, while the EFI drivetrain chapters are marked for the injected cars.

Those include fuel injection fault codes and circuit tests, fuel delivery checks, engine removal and overhaul with clearances, and ignition, starting and charging diagnosis. Torque figures are tabulated and the wiring diagrams cover the full harness.

The beverage body changes access more than it changes mechanics, so panel removal sequences are worth reading before you start. Verify YUM2A24_BEVER on the vehicle identification first.

Fault diagnosis on the injection side is a sequence: read the code, test the named circuit against its stated value, then decide. Nothing in the book asks you to guess at a component.
