Code YUM2A24 belongs to the 2024 UMAX 2 EFI. Service reference is LIT-19616-A3-12.
That manual was written for eight 2024 UMAX configurations, so it documents the two-passenger EFI car alongside its electric and Rally siblings. Chapters shared between them, body and chassis, brakes, steering, suspension, wheels, are written once; the engine and fuel sections belong to the EFI cars specifically.
Fuel injection coverage includes fault code retrieval, sensor and actuator testing and fuel pressure checks. Engine work runs from removal through overhaul with the clearances and torque values a rebuild needs. Ignition, starting and charging tests are given as measurements against stated values.
Before you start, confirm the vehicle reads YUM2A24 and pair that with part number LIT-19616-A3-12 when sourcing parts.
