Models Covered

This manual covers two 2024 NMAX variants:

• GPD155D-A (model code BLS1) — equipped with ABS, YECVT, and the full infotainment display.
• GPD155D-F (model code BTD1) — equipped with YECVT and a multi-function meter unit.

Where procedures differ between the two variants — such as ABS service for the GPD155D-A, wiring diagrams, or diagnostic code tables — the manual clearly identifies which model the information applies to.

• Self-Diagnostic Function — Fuel Injection, ABS, Smart Key System, YECVT System
• Wiring Diagrams (GPD155D-A and GPD155D-F)

Across its nine chapters, this 2024 NMAX service manual walks through everything from routine oil changes and valve clearance adjustment to complete engine disassembly, YECVT initialization, ABS hydraulic unit testing, and smart key registration. The specification chapters alone provide a full reference of tightening torques, service limits, clearances, fluid capacities, and electrical values, while the wiring diagrams at the rear of the book map every connector, coupler, and ground point for both model variants.

The engine chapter alone spans lubrication diagrams, compression testing, engine removal and installation, cylinder head disassembly with valve spring and valve guide measurement, camshaft lobe dimension checks, piston and cylinder bore measurement, and crankshaft runout limits. The V-belt automatic transmission chapter covers primary and secondary sheave disassembly, clutch shoe thickness measurement, V-belt width limits, and the YECVT system’s electrical and mechanical components.

What This Manual Helps You Do

With this 2024 Yamaha NMAX GPD155D-A GPD155D-F service manual on hand, you can confidently tackle:

• Routine maintenance: engine oil and final transmission oil changes, coolant replacement, air filter and V-belt case filter service, brake fluid bleeding, spark plug inspection, valve clearance adjustment, and throttle body cleaning.
• Engine repair: cylinder head removal and installation, camshaft and rocker arm service, piston and ring replacement, crankshaft removal and reassembly, and timing chain checks.
• Transmission service: V-belt replacement, primary and secondary sheave disassembly, clutch inspection, YECVT motor removal, and primary sheave origin position initialization.
• Fuel and emissions: fuel pump pressure testing, fuel injector diagnostics, ISC unit cleaning and learning value reset, and O2 sensor troubleshooting.
• Electrical diagnostics: fault code reading and clearing via the Yamaha diagnostic tool, sensor operation tables, actuator operation tests, and complete wiring schematics for both GPD155D-A and GPD155D-F.
• ABS service: hydraulic unit operation tests, brake line routing confirmation, wheel sensor inspection, and ABS warning light troubleshooting.

Every procedure in this manual is laid out with step-by-step instructions, exploded diagrams, and the exact torque values Yamaha specifies. Whether you are replacing a V-belt, resetting the oil change indicator, or chasing down an intermittent electrical fault, the Yamaha NMAX GPD155D-A GPD155D-F workshop manual removes the guesswork.

Why It Matters

Working on a modern scooter like the 2024 NMAX without the correct specifications is risky. The YECVT system requires precise initialization after any primary sheave or TCU work. The ABS hydraulic unit demands careful bleeding and operation testing. Torque values for critical fasteners — from the primary fixed sheave nut to the steering head ring nuts — are not generic; they are specific to this machine. Using the wrong figure can lead to component damage, unsafe handling, or a repair that fails shortly after.

This manual gives you the same reference data a Yamaha dealer technician uses, including diagnostic code tables, sensor operation tables, and actuator test procedures. It is the difference between hoping a repair will work and knowing it will.
