Yamaha's 2025 manual for AC-drive UMAX cars is LIT-19616-A3-90, and the UMAX 2 PowerTech AC is listed in it under YUM2E25.

Four 2025 configurations share the volume, all on the electric side, which keeps the electrical chapters central rather than tucked behind engine sections. Motor and controller diagnosis, battery pack and charging service, and harness testing all get full treatment with stated test values.

Mechanical coverage runs through the brakes and parking brake, steering, front and rear suspension, wheels, rear axle and body panels, with torque tables and wear limits. The wiring diagrams are complete, and the fault charts start from what the car is doing.

Check that your vehicle identification reads YUM2E25 before working from a specific procedure or ordering from a figure.
