Model code SW1NLLPPL belongs to the 2023 L-TX LE EPS, and the service manual for it is LIT-12618-03-90. Yamaha covered seven sleds in that volume: this one with the L-TX GT EPS, L-TX SE, S-TX GT EPS, SRX LE EPS, X-TX LE and X-TX SE.
With power steering fitted, the electrical chapters carry more weight than they once did on a snowmobile. The manual gives the assist system's test procedures and expected values, and it keeps them separate from the general chassis electrical material.
Everything else is present as well: maintenance intervals, engine and turbo overhaul with torque figures and clearances, fuel-injection diagnosis, clutch and drive-belt specifications, suspension and track adjustment, brake service, steering, wiring diagrams and the troubleshooting sequences.
