Mitsubishi Fuso Truck & Bus TRUCK, BUS 2009 Repair Manual

You’ve got a truck with a busted harness. Maybe a short, maybe a broken connector, maybe corrosion in a terminal. You’ve been there—chasing wires, guessing which terminal tool fits, hoping you don’t pop an airbag or short out a sensor that costs more than the job is worth. The Mitsubishi Fuso Truck & Bus TRUCK, BUS 2009 Repair Manual is what you need on the bench. 355 pages, OEM factory print from September 2009. No aftermarket garbage. This is the actual document Mitsubishi Fuso Truck & Bus issued to their dealers for harness repair, not some third-party rewrite that loses the critical notes on waterproof grease and proper crimp force.

What the Mitsubishi Fuso Truck & Bus Repair Manual Covers

The manual is split into four main sections. First, Descriptions of Procedures—that’s the how-to for electrical system maintenance, connector repair, waterproof grease application, and airbag handling. The INDEX lays out the entire structure. Second, Supplied Parts List—includes special tool numbers like caulking tool MH063570 and MH063677. Third, Procedures for Each Connector—33 different connector types from AA (NMWP) to PG (187+090II). Fourth, Terminal Tool (Releasing Tool) List. That’s it. No extra chapters on engine rebuild. Just harness work, done right.

Connector Repair: 33 Types from NMWP to High-Pressure Waterproof

Each connector type gets its own procedure. You get the correct caulking tool, the proper heat shrink method—Dura seal or NICHIFU seal—and explicit instructions for assembly and removal. The manual covers waterproof, non-waterproof, high-pressure waterproof connectors. If you’re working on a 2009 Mitsubishi Fuso TRUCK or BUS, you’ll find the exact connector you’re dealing with. No guesswork. For example, the BS/BU connector (DSD/RDSD) is in section 3-12. You’ll see the pin layout and the correct terminal release tool.

Read the Airbag Section Before Starting

Section 1, point 3: Points to note on vehicle with airbag. If you’re touching anything near the SRS system, read that first. I’ve seen techs blow airbags by shoving a test light into the wrong pin. This manual tells you the procedure to avoid that. It’s not a suggestion. It’s a safety requirement.

Don’t skip that section.

Why Factory OEM Harness Repair Data Matters

Aftermarket manuals love to say ‘generic wiring diagram’ or ‘typical connector pinout.’ That’s how you burn up a $2000 ECU or cause an intermittent short that makes the truck fail a safety inspection. This is Mitsubishi Fuso Truck & Bus’s own document. They built the harness. They know the exact waterproof grease spec—it says ‘waterproof grease’ in section 1, points to note on repair of connectors. They know the exact crimp stroke for each terminal—the manual lists caulking tool numbers for each connector type. The precision is the same as a torque spec on a head bolt. You follow this, you get a repair that lasts. If you want to understand the basics of how an Internal Combustion Engine works, that’s another document. For the harness, this is it. Period.

Tools You’ll Need for Harness Repair

The Supplied Parts List includes special tool numbers. Caulking tool MH063570 for one type, MH063677 for another. The manual tells you which tool for which connector. You don’t guess. You buy the right tool or borrow it. Also listed are other supplied parts—terminals, seals, boots. If you’re rebuilding a connector, you order those parts. The contact info for ordering is in section 2.

If you’re working on other vehicles, the same OEM philosophy applies to Interact 4.0, 6.0 2003 Repair Manual – OEM Factory Specs, Ika-renault 627, 626 1973 Repair Manual | OEM Factory Specs, and Minsk MINSK Repair Manual – Factory Repair Procedures for Two-Stroke Workhorse.

Frequently Asked Questions

Does this manual include engine or transmission repair procedures?

No. It covers only the wiring harness and connector repair.

How is this different from a generic wiring diagram?

A generic wiring diagram might show pin colors but won’t tell you which special tool to use for releasing the terminal, whether the connector is waterproof or high-pressure waterproof, or how to correctly apply heat shrink. This manual comes from Mitsubishi Fuso Truck & Bus and includes every detail: the types of grease, the caulking tools (MH063570, MH063677), the order of assembly for each connector type, and the safety precautions for airbag systems. If you’re working on a 2009 Fuso truck or bus, this is the only document you should trust.

If you need to rebuild the gearbox, the Manual Transmission service manual from the manufacturer is your next stop.

Stop wasting time with forum hacks and aftermarket PDFs that skip the critical steps. Access the Factory Manual from AutoRepairManuals and have the actual OEM document on your tablet or printed at the bench. You’ll thank yourself when the harness repair holds up for years.
