Frequently Asked Questions
Does this manual cover both the FK and FM model designations?
Yes. The manual addresses all three chassis codes sold under the Second Generation Fuso Fighter banner — FK617, FM617, and FM657 — covering cab-over medium-duty configurations in both single and tandem rear-axle layouts produced between 2002 and 2004.
Is the 6D16-T3 engine covered separately from the 6D16-T2?
Both turbocharger variants of the 7.5L 6D16 inline-six are documented within the same engine section. Specifications, torque values, and fuel system calibration data are clearly differentiated between the T2 and T3 tune levels throughout the manual.
Does the manual include wiring diagrams for the automatic transmission controller?
Complete electrical schematics are included for all four transmission options — the 4-speed and 6-speed automatics as well as both manual gearboxes. Transmission control unit wiring, solenoid identification, and shift-quality diagnostic charts are all present.

The manual is a PDF file with zoom-capable illustrations, menu-driven navigation, and full wiring diagrams.
