2009 Yamaha VMAX VMX17Y(C) Service Manual (P/N LIT-11616-22-64)

• Coverage and document identity: Covers the 2009 Yamaha VMAX VMX17Y(C), including model code 2S31 (USA) and 2S32 (California). The set contains 585 PDF pages total: the 584-page, first-edition Yamaha service manual, P/N LIT-11616-22-64, plus the one-page Yamaha Tech Bulletin M2012-003.
• Engine and transmission repair: Covers engine removal and installation, camshaft and timing-system work, cylinder-head and valve service, clutch and hydraulic controls, crankcase separation, connecting rods and pistons, crankshaft and balancer inspection, transmission assembly, and middle-gear backlash and alignment.
• Chassis, brakes, and shaft drive: Details wheel removal and static balancing, ABS wheel-sensor service, brake caliper and master-cylinder repair, ABS hydraulic-unit operation tests, fork disassembly, steering-head and swingarm service, rear-shock removal, and final-drive backlash adjustment and gear alignment.
• Fuel, intake, and cooling systems: Includes fuel-pump and injector pressure testing, throttle-body cleaning and synchronization, throttle- and accelerator-position sensor adjustment, YCC-T/YCC-I system coverage, EXUP cable adjustment, and repair procedures for the radiators, oil cooler, thermostat, and water pump.
• Electrical and fault diagnosis: Provides circuit diagrams and troubleshooting for ignition, starting, charging, lighting, signaling, cooling, fuel injection, and the fuel-pump system, along with ECU diagnostic mode, FI fault isolation, ABS fault-code diagnosis and deletion, and component-level electrical tests.
• Workshop diagrams and specifications: Supplies exploded job charts, torque tables, fluid-capacity data, inspection limits, electrical test specifications, an engine-oil lubrication chart, cooling-system diagrams, cable-routing drawings, ABS connector views, and the full VMX17Y(C) wiring diagram.

Factory Coverage and Intended Use

Yamaha produced this manual primarily for its dealers and qualified mechanics, and it assumes a basic understanding of motorcycle mechanics and repair techniques. It is suited to experienced technicians and mechanically capable owners who already have the tools and background required for major engine, brake, fuel-system, and electrical work; it is not a simplified owner-maintenance guide.

The core publication is specific to the 2009 VMX17Y(C). USA and California differences are carried into the specifications and routing information, including California-only evaporative-emissions canister checks and hose routing. The separate M2012-003 bulletin has a narrower purpose: it corrects two crankshaft-position references in the valve-clearance adjustment procedure on page 3-5 and applies that correction to all 2009–2012 VMX17(C) models. It does not provide full later-model service coverage.

Repair Depth Beyond Routine Maintenance

Periodic service sections cover valve-clearance adjustment, throttle-body synchronization, engine-oil pressure measurement, hydraulic clutch bleeding, coolant replacement, ABS brake bleeding, steering-head adjustment, suspension settings, and final-drive oil service. The repair chapters go much further. Engine work includes the decompression system, timing-chain guides and tensioners, valve guides and seats, starter clutch, oil pump and relief valve, crankshaft and balancer bearings, shift drum and forks, and the middle drive and driven pinion assemblies.

Chassis procedures address front and rear wheel-sensor rotors, brake hydraulic components, ABS hydraulic-unit removal and testing, fork internals, suspension linkage, swingarm, drive shaft, and final-drive pinion/ring-gear setup. Exploded views are paired with job charts that identify removal order, parts, replacement items, lubrication points, and related technical data without leaving the technician to infer assembly sequence from a parts illustration alone.

Electronic Systems, Schematics, and Diagnostic Support

The opening feature section explains FI operation, ABS functions and self-diagnosis, and Yamaha Chip Controlled Throttle and Intake operation. In the electrical chapter, that system overview is backed by ECU diagnostic mode, symptom-based test paths, fault-code checks, sensor and actuator testing, and dedicated ABS warning-light and fault-code workflows.

Useful visual references include the engine-oil lubrication chart, cooling-system diagrams, cable-routing drawings, fuel-injection circuit diagram, ABS component and coupler-location charts, and the VMX17Y(C) 2009 wiring diagram. The 71-page specifications chapter also consolidates engine, chassis, and electrical specifications with tightening torques, lubrication points, system diagrams, and routing information.

Special Tools and Repair Cautions

The manual identifies Yamaha tools by number, including the test coupler adapter 90890-03149, vacuum gauge 90890-03094 / YU-44456, fork seal driver 90890-01502 / YM-A0948, middle-gear backlash tool 90890-04080, radiator cap tester 90890-01325 / YU-24460-01, and fuel-pressure equipment 90890-03153 with adapter 90890-03176.

Its repair cautions are component-specific. Incorrect camshaft-cap bolt release can damage the cylinder heads, camshafts, or caps, while foreign material left in a wheel hub can damage the inner ABS sensor rotor and wheel sensor. Brake/ABS hydraulic work, pressurized fuel testing, and internal engine repair should be performed only with the required mechanical knowledge, proper support equipment, and the complete factory procedure in front of the technician.
