    Hitachi problem : What are the solutions?

    A large proportion of HITACHI's public works machines are equipped with ISUZU engines, mainly with Adblue SCR and DOC systems. These engines, although very reliable by design, can occasionally have problems with exhaust gas treatment. We'll show you below what our troubleshooting solution can do for you.

    Isuzu AdBlue engine types and problems

    Engines meeting the Tier IV standard may be subject to some AdBlue system failures. More specifically, we're talking about FT4 (Final Tier 4) engines.

    • ISUZU 6WG1
    • ISUZU 6UZ1
    • ISUZU 6HK1
    • ISUZU 4HK1
    • ISUZU 4JJ1

    If the above Isuzu engine codes don't appeal to you, please note that the following machines are supported (non-exhaustive list). Here is a list of some excavators, but other machine models such as ZW550 loaders are also supported, which is why we prefer to know the engine code above.

    • ZX130-6
    • ZX160LC-6
    • ZX180LC-6
    • ZX210LC-6
    • ZX210-6
    • ZX250LC-6
    • ZX300LC-6
    • ZX350LC-6
    • ZX380LC-6
    • ZX470LC-6
    • ZX670LC-6
    • ZX870LC-6
    • ZX135US-6
    • ZX245USLC-6
    • ZX345USLC-6
    • ZX190W-6

    How do I fix an Adblue fault in a Liebherr or Deutz engine?

    On HITACHI mining and public works machines equipped with ISUZU Tier IV / Stage IV engines (some with Adblue/DOC/EGR systems), a fault in the exhaust aftertreatment system will result in a major operating failure.

    • Power loss
    • Torque restriction
    • Limp Mode
    • Complete machine shutdown after several hours in fault condition

    To solve an AdBlue Hitachi Isuzu engine problem, our solution is to isolate the fault so that it no longer transmits information on the vehicle's CAN-Bus network, and thus stops faulting the engine management system.

    How to inhibit the Adblue system on a Hitachi ISUZU engine

    To solve the problem of restrictions due to incorrect information being sent to the vehicle's Can network, we use a virtualization module we've specially developed to run on Hitachi machines. In fact, our module is programmed upstream and grafted onto the vehicle's harness so that it sends AdBlue information rather than the basic management module.

    • Your machine regains its full power and torque
    • The vehicle is no longer in degraded or crawling mode with a limited maximum speed.
    • As a result, the hydraulic system regains its efficiency, with bucket lifting speeds returning to their original levels.
    • Lights on the dashboard disappear

    Advanced features and functions of the data virtualization module

    • AdBlue level remains constant and does not drop
    • AdBlue quality always correct
    • Sensors emulated to transmit information expected by the engine ECU
    • Frames sent over the CAN network do not interfere with other modules
    • You can return to the original configuration at any time by dismantling the box or disconnecting its power supply.
