This Mitsubishi FC/MC Controller Service Manual is the complete technical guide for the controller system used in FB13-20PNT and FB16-20PN series forklift trucks. It covers five or seven independent controllers linked by a Controller Area Network (CAN), the logic unit at the heart of the control system, and the inverters and EPS controller that drive each motor. The manual walks through every stage of controller operation — from system layout and communication protocols to detailed setup options and diagnostic procedures.

Inside, you’ll find complete troubleshooting procedures for every error code the controller can display, from traction motor overheating (E0, E1) and inverter faults (E5, E6, E7) to current sensor faults (14, 24, 34), contactor faults (40, 41), and sensor issues (50, 51, 80, 81, 82). Each error code section includes the fault condition, possible causes, step-by-step checks with connector references, and the correct repair procedure. The Run Time Diagnostics table lists every error code with its display icon, restriction, and recovery method, so you can quickly identify what the truck is telling you.

The manual also provides complete removal and installation procedures for the inverter, DSP card, logic unit, EPS controller, logic card, power supply card, input unit, and output unit — with all required discharge procedures for the inverters before working on the electrical system. Basic check procedures cover testing tools, card voltage measurement with pin-by-pin voltage charts for the logic card, power supply card, DSP cards, input unit, output unit, and EPS controller, plus contactor coil and tip inspection, inverter checking, and regeneration testing.

For technicians servicing the motors, the manual covers the traction motor, pump motor, and EPS motor in detail — specifications, structures, disassembly sequences, inspection procedures for rotors, bearings, splines, and insulation, and reassembly with all torque values. The circuit diagram chapter explains how to read the schematic and connector diagrams with all symbols, color codes, and equipment numbering, followed by the complete circuit diagrams for the FC/MC controller system.

The setup options section is comprehensive, covering Group 1 (basic functions like acceleration rate, travel speed limit, and service indicator), Group 2 (detailed functions like auxiliary inputs, regeneration adjustments, and steering settings), and Group 3 (model information including truck type, battery voltage, battery type, hydraulic control selection, mast type, and valve section). Each option is explained with its range, default value, and harness pin numbers.

Whether you’re diagnosing a fault code, replacing a controller component, setting up a new logic card, or servicing the motors, this manual gives you the correct procedures and specifications to get the job done right. It’s the same technical documentation used by professional forklift technicians, covering every aspect of the FC/MC controller system for these Mitsubishi electric forklift models.
