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.
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.
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.
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.
