2002 Yamaha G20-AX "CONCIERGE 4/6" (CARB) Service and Rep...
LIT-19616-G2-0A covers the 2002 G20-AX Concierge 4/6, the last of the three model years Yamaha put inside this one manual. The code on the car reads G20AX.
Coverage begins with the 2000 cars and runs through 2002, taking in the G20-AU and G20-AW as well, so the differences between seasons are handled in the same pages rather than left to guesswork. Quote the part number and the code together and you can be sure the reference matches the machine.
Inside, the layout follows the factory pattern: identification and specifications, periodic service, engine overhaul, fuel system, power train, brakes, steering, chassis and electrical. Wiring diagrams are complete rather than simplified, which is what you need when a switch or solenoid is suspected.
This is the same documentation a Yamaha dealer technician would open to diagnose a running complaint or rebuild a component on a Concierge that has carried passengers for two decades.
