2021 Yamaha UMAX RALLY 2+2 AC Service and Repair Manual
From 2020 through 2023 Yamaha covered the AC Rally 2+2 in one volume, LIT-19616-A0-37, and the 2021 car, code YUM2E21_UMAXCG, is in it.
Eight configurations across those four model years share the book. That continuity is useful on a car that saw running changes: where a specification differs between years the manual names the code it belongs to.
The drive chapters cover motor removal and testing, controller fault diagnosis, battery pack service and the charging system, each with expected values. Chassis work spans brakes and parking brake, steering, front and rear suspension, wheels, rear axle and the 2+2 body and seating. Torque tables, wear limits and full wiring diagrams are included.
