The manual provides detailed coverage of diagnostic communication with on-board ECUs that incorporate diagnosis functions, including reading error codes, displaying actual values (service data), actuator testing, coding/resetting/programming adaptations, and transferring data between the FUSO Diagnostics system and USB storage devices. It walks through vehicle model selection, safety rule confirmation, quick test execution, and interactive troubleshooting for each control unit. The coding sections cover manual settings, default string parameters, and injector injection quantity adjustment with authentication via inquiry number and password obtained from the FRN. The FRN section explains how to download ECU data, request rewriting data, upload history, and search past rewrites.

What This Manual Enables You To Do

This FUSO Diagnostics operation manual gives technicians the complete workflow for diagnosing and servicing Mitsubishi Fuso trucks and buses equipped with on-board electronic control units. It covers the full diagnostic process: connecting the FUSO Connect interface between the PC and vehicle, running quick tests across all control units, reading and clearing error codes, monitoring actual values in table/bar graph/curve graph formats, and performing actuator tests.

The high-functional operations section is particularly valuable for part replacement and repair scenarios. It details how to change coding parameters when vehicle specifications are modified, how to perform control unit replacement when an ECU is swapped, how to reprogram software during service campaigns, and how to reset learned values after component replacement. Each procedure includes the authentication steps (inquiry number and password from FRN), the parameter values to select, and the after-run process required for changes to take effect on the ECU.

The manual includes extensive examples of use in part replacement and repair, with detailed coding tables for Canter, Rosa, Fighter, and Super Great models. These cover injector replacement, PTO installation, cab-back engine control, air conditioning, headlamp leveling, ISS equipment, exhaust brake, speed limiter settings, and more. The FRN section explains how to download ECU data before starting work, request rewriting data from the server, upload history after completion, and cancel or search rewriting records.

For technicians and workshops, having the correct diagnostic procedures and coding parameters is essential to avoid incorrect ECU configuration that can cause error codes, equipment malfunction, or vehicle performance issues. This manual provides the exact parameter options, authentication requirements, and step-by-step screens needed to complete each operation correctly.
