The Hitachi Construction Company Ltd is an internationally renowned manufacturer of various types of construction equipment. Along with this niche, it is also into sales and service of transportation machinery, and other machines. The company is no longer a subsidiary of the Hitachi Group.
The Hitachi Construction Company was established in 1970 and was involved in the production and manufacture of the first Japanese mechanical excavator. It has since grown exponentially and is today one of the largest and major manufacturers of construction equipment in the world.
Hitachi started its manufacturing journey with bulldozers, crawler cranes that was subsequently transferred to Hitachi Sumitomo Heavy Industries Construction Crane Ltd, and excavator models UH- and EX-series. These are not among the company’s products today. Presently, Hitachi is a major manufacturer of Excavators model ZX series, loaders, recycle machines, and dump trucks.
Now, where does the Jaltest Hitachi diagnostic tool for construction equipment come into the picture?
All modern vehicles, construction equipment, or material handling equipment have an onboard computer that indicates through fault codes any malfunction in systems or parts of the vehicle or equipment. Also known as Diagnostic Trouble Codes (DTCs), these codes are shown on the display system just below the dashboard on the driver’s side.
The same goes for Hitachi construction equipment too. You can then take the help of the Hitachi diagnostic software to interpret the code, identify the source of the malfunction, and then be guided on corrective actions to be taken up.

Functioning Of The Hitachi Diagnostic Software
The Jaltest Hitachi scan tool offers options to check the health of the equipment and ensure that it is always in peak operating condition. There are two ways to go about it, preventive maintenance and troubleshooting by symptoms.
The first is diagnostics which are done at the first hint of trouble to ensure that a minor issue does not become a major full-blown problem at a later date leading to downtime. This is done by periodically scanning the equipment and figuring out whether there are any slight trouble that can lead to potential severe faults later.
Generally, such issues do not cause much trouble and are known as temporary fault codes. Suppose our Hitachi excavator diagnostic software identifies an issue with the transmission of an excavator. In case it persists and does not go away within a few driving cycles, more attention should be given to it since it might transform to a permanent fault code in the future.
Now, once a permanent fault code is detected, the same Hitachi excavator diagnostic tool will tell you what the fault code refers to it and suggest actions that will clear it. Our user-friendly software makes sure that your equipment is always on the job and any fault code is read and cleared at the earliest.
Deep Coverage With The Jaltest Hitachi Scan Tool
If you are operating or own a fleet of Hitachi construction equipment such as excavators, loaders, front shovels, and others regardless of the models, our Hitachi diagnostic tool is a must-have. You ensure that no malfunction goes unnoticed and you do not suffer because a small problem has escalated into an unmanageable permanent fault code leading to downtime and loss for your business.
Our Hitachi excavator diagnostic software offers excellent coverage of your construction equipment of this brand. You can carry out basic procedures to keep your equipment running or in case of more critical fault codes, perform complex procedures like force regents to bring your equipment back on the job.
Additionally, you get access to our user-friendly dashboard which provides a wide range of technical data and information that allows you to carry out bi-directional functions and control engine operating speeds and oil flow adjustments through detailed live data monitoring wiring diagrams.
No job is too difficult for the Hitachi scan tool as you get services that are typically offered at the dealer level.
Hitachi Excavator Diagnostic Tool And Force Regens
One of the most complex activities that is facilitated by our Hitachi diagnostic software is force regens. It becomes necessary for equipment that is powered by diesel engines, something that is very common on Hitachi excavator models. So, what is the Hitachi construction equipment fault code that requires forced regens to clear it?
Even though our Hitachi excavator diagnostic software is highly optimized to settle issues with transmissions, hydraulics, lights, and more, forced regens are a very critical activity that it does to keep the engine running without a break. Forced regens is carried out when there is a large soot buildup in the diesel particulate filter of diesel engines and the vehicle or equipment goes into limp mode in the most severe cases.
It typically happens when the usual passive regens cannot clear the soot in the DPF and forced regens activity must be done. It is a phenomenon that is typically seen in engines that are not run on long stretches but have stop-go actions continuously. Forced regens is the highest form of DPF regeneration.
Our Hitachi diagnostic tool through the onboard computer will warn you if soot has accumulated in the DPF and requires clearing up. The software will guide you through the power of force regens required from High to Very High. To perform forced regens, the engine should be running for about 40 minutes at an RPM to be calculated by the maintenance tool. This raises the temperature of the exhaust gasses which ultimately burn the soot off the diesel particulate filter.
Hitachi Excavator Diagnostic Software – Clearing Fault Codes
We have seen in this post how the Hitachi diagnostic tool reads and clears any malfunction with your equipment as shown by fault codes in the onboard computer. While fault codes are not standardized, they are common among different models of equipment. For instance, the Hitachi excavator diagnostic tool analyses the fault codes of most series of Hitachi excavator issues and provides cutting-edge solutions.
Here are some fault codes of Hitachi excavators and what that means for you.
- 11100-2 engine speed is abnormal
- 11101-3 engine speed control knob sensor high pressure abnormal
- 11200-3 Pump 1 oil pressure sensor high pressure abnormal
- 11200-4 Pump 1 Oil pressure sensor low pressure abnormality
- 11301-3 Rotary pilot pressure sensor high pressure abnormality
- 11302-3 Boom lifting pilot pressure sensor high pressure abnormality
- 11302-4 Boom lift pilot pressure sensor low pressure abnormality
- 11304-4 Walking pilot pressure sensor low pressure abnormality
- 11400-2 Pump 2 Maximum Flow Limit Control Solenoid Valve Current Feedback Abnormal
- 11401-2 Torque control solenoid valve current feedback abnormal
Now let us check an example of the full process that our Hitachi excavator diagnostic software will take you through.
Fault code: 11301-3
- Fault problem: high pressure abnormality of rotary pilot pressure sensor
- Fault reason: voltage 4.75V or above
- Affected control: (1) Stick regeneration control (2) Attachment flow control (3) Slewing alarm control
- Symptoms of machine operation when the fault occurs: (1) Stick retracting and swiveling combined operation stick speed is slow (2) If the machine is equipped with a swing alarm and when the swing alarm is active, the swing alarm continues to sound
- Remarks: (1) Check the wiring harness (2) Replace the rotary pilot pressure sensor
As can be seen, our Hitachi diagnostic tool takes you through the full gamut of fault clearance. It starts from the time a fault code is detected on the onboard computer and reflected in the software after our laptop is linked to the equipment, right up to the time the fault is cleared.
Live Data Monitoring and Technical Information From the Hitachi Scan Tool
Our Hitachi diagnostic software for construction equipment provides deep coverage of all critical parts and components including engines, hydraulics, transmissions, body computers, and more. The goal is to ensure that temporary faults do not become major permanent ones and arrive at resolutions that always keep your equipment running at optimum efficiency.
Take the instance of Isuzu and Cummins engines that power Hitachi equipment. In case there is soot accumulation in the diesel particulate filter of the engines, the software warns you that necessary action is required to prevent disruption of work. All parameters of the engines are before you on the diagnostic menu of the Cummins or Isuzu engine code reader and you can take any corrective action and dealer-level servicing without having to fall back on the manuals.
Our software is flexible enough to allow you to set metrics within which you want your equipment to function. These might be engine operating speed, pressure accumulator, oil flow adjustment, and any other that you want to adjust to maximize the use of your equipment. With Cummins and Isuzu engines, you can even set up flows and pressures on excavators, calibrate transmissions in wheel loaders, and other dealer-level services.
