Caterpillar is a brand to reckon with in various sectors. They are the world’s top manufacturer of diesel and electric locomotives, industrial gas turbines, construction and mining equipment, off-highway gas and diesel engines, and material handling equipment such as forklifts. For more than a century, Caterpillar has maintained standards that are synonymous with ruggedness, durability, dependability, and quality right across their product range.

Caterpillar has always kept up with the times and has implemented cutting-edge technological innovations in their products. Recently, they have launched machinery that leaves behind a vastly reduced carbon footprint than before. Another example is the CAT Command, which allows operators to take control and operate the equipment while outside their machines. This is a very useful high-tech feature that is very critical when working on challenging and difficult terrain and considers the safety of the operators.
However, the best machines do face issues and owners should be prepared to resolve them at the earliest possible time. The same is true for Caterpillar equipment too. If you have a fleet of construction equipment such as dozers, excavators, skid steers, compact track loaders, articulated trucks, motor graders, and material handling equipment like forklifts, the CAT diagnostic software is a must-have tool for you.
Even though Caterpillar manufactures machines and equipment across several sectors and industries, this post will be limited to the use of the Caterpillar diagnostic scanner for construction and material handling equipment only.

Functions of the Caterpillar Diagnostic Maintenance Tool
The CAT diagnostic software offers deep coverage of a wide range of equipment of various makes and models. Among the leading ones covered by our Jaltest software are the CAT d6t dozer, CAT 930H wheel loader, CAT 259D compact track loader, 336F excavator, Skid steers, and many others. With the software, you can quickly check for fault codes and have them cleared before a minor issue becomes a full-blown one, leading to downtime and upsetting your project deadlines.

Before proceeding further, a quick word on fault codes is necessary since they have a big role to play in the working of the software, and clearing the codes will keep your equipment on the job.
Fault codes, also known as Diagnostic Trouble Codes (DTCs) are codes in alpha-numeric format that pop up on the display panel of the onboard computer in Caterpillar machines whenever there is a malfunction in systems or components. At this point, you must connect the Jaltest Caterpillar computer diagnostic software to the onboard computer to identify and interpret the numbers and take corrective action to clear the fault codes.
The benefit of the Caterpillar diagnostic tool is that once the issue is identified, the software takes over and handholds you through what is necessary to clear the trouble. The Jaltest software provides detailed wiring diagrams so that you can quickly locate where the fault lies and ensure that it is rectified.

Moreover, the Jaltest CAT digital diagnostic tool provides technical data and information in real time so that the solutions implemented are what you will expect from company-certified engineers. Hence, any fault code is cleared in-house without wasting time waiting for technicians to show up.
Our Jaltest CAT diagnostic software has a very user-friendly and intuitive dashboard. Once you connect it to the onboard computer, you get the complete picture of the current health of your equipment. Fault codes related to engines, hydraulics, transmissions, brakes, HVAC, and others will show on our maintenance tool and you will be guided on how best to clear them.
It is not necessary that you should wait for fault codes to show up, scan the system by symptoms and then initiate the required fault code clearance activities. Our Jaltest CAT diagnostic software has a provision for preventive maintenance too. You simply have to choose the “full system scan” and run the maintenance tool. It will automatically scan all the systems and inform you of any potential faults, even minor ones.

If these fault codes are temporary in nature, generally no action is required as they will disappear within a few driving cycles. If not, consider them to be permanent fault codes where complex actions by the Caterpillar diagnostic tool are required to eliminate them and bring your equipment back on the job again.
Highlights of the CAT Digital Diagnostic Tool
The Jaltest Caterpillar diagnostic maintenance tool has a wide range of advanced features and cutting-edge capabilities. On one hand, you can diagnose various components by symptoms such as engine, hydraulic systems, powertrain, instrument cluster, transmission, and more. On the other, you can carry out fault prevention actions by calibrating joysticks and booms, setting up flows and pressures on excavators, performing dump on wheel loaders, calibrating the blade on a motor grader and transmissions, and others.

You thus ensure comprehensive coverage and troubleshooting of your Caterpillar equipment with our Jaltest CAT diagnostic software. Further, it is not only mobile equipment that is covered by the Jaltest diagnostic tool, it is also very effective for stationary equipment with Perkins engines and troubleshooting crushers, screen plants, tower lights, generators, and more.
Caterpillar Engine Diagnostic Codes
Whenever you feel or hear anything out of the ordinary while operating Caterpillar equipment, stop immediately and look for the source of the issue through Caterpillar engine diagnostic codes.
Here are some examples of CAT engine trouble codes.
- P0300: Random or Multiple Cylinder Misfire Code.
- P0301 through P0308: Single-Cylinder Misfire Codes.
- P0446: Evaporative Emissions Control System Codes.
- P0455: Evaporative Emissions Control System Codes - Leaks.
- P0420 or P0430: Catalyst Efficiency Codes.
Another frequently observed issue with CAT diesel-powered engines is the clogging of the Diesel Particulate Filter (DPF). This component is designed to lower the emission of particulate matter which then gets trapped in the DPF, leading to soot accumulation. In severe cases, the engine might seize up or the equipment might go into limp mode.
Here, the Caterpillar engine diagnostic codes will recommend forced regens, an activity that is necessary when passive regens are unable to clear the soot. This requires running the engine on high rev in a stationary position for about 40 minutes or till such time as the rise in temperature of the emission gasses clears away the soot buildup.
There are several other diagnostic codes and rectification actions that need to be taken to keep your Caterpillar engines operating at peak efficiency.
Caterpillar Diagnostic Codes And CAT Hydraulic Systems
Hydraulic systems are key to Caterpillar construction and material handling equipment, whether it is dozers, excavators, and others. Even when you clear Caterpillar skid steer diagnostic codes, hydraulic systems take center stage as here too it is very crucial for smooth operations.
Hydraulics must work to match your needs. Even though they come with factory settings that meet standard operating conditions, our Jaltest CAT digital diagnostic tool will help you to calibrate it as per the demands of your project. For challenging terrain, you can calibrate the hydraulic systems with our powerful CAT diagnostic software to ensure peak performance.

While there are several types of Caterpillar equipment that use state-of-the-art hydraulics, let us take the example of CAT excavators to understand the concept of hydraulics calibration with our Caterpillar computer diagnostic software.
Carrying out CAT excavator hydraulic calibration is a complex task and involves adjusting settings and parameters in the system to ensure peak performance in existing conditions. You must set values like pressure, flow rate, and control response to get the best from your equipment.
Calibrating hydraulic systems of CAT excavators with our Jaltest Caterpillar diagnostic scanner typically requires calibration of key components like attachment controls, position sensors, and solenoid valves. All these in combination prepare your excavators to work in any conditions that you might face.
When using our top-of-the-line Jaltest Cat diagnostic software you will be optimally guided with specialized excavator hydraulic system diagrams so that you will know the precise settings and calibration points that must be implemented in the excavator. All that you must do is connect our CAT diagnostic software laptop to the onboard computer of the excavator to be precisely guided through the parameter setting and calibration process.

The reason for CAT hydraulic calibration is to maintain smooth operations of your equipment. The key components that can be calibrated are the hydraulic cylinders, steering controls, position sensors that monitor attachment positions, and solenoid valves that control specific hydraulic functions like bucket movement in CAT excavators. Further, you can adjust flow rates and pressure levels, and control valve timings and position sensor readings.
Now that you know the intricacies of calibrating CAT hydraulic systems with the Jaltest Caterpillar diagnostic maintenance tool, let us understand why it is so important.
First, hydraulic calibration improves efficiency as the precise controls and settings lead to better productivity and fuel economy. It also results in maximizing operations and reducing wear and tear on the hydraulic systems. Finally, hydraulics calibration makes the machine’s response consistent, dependable, and predictable, thereby increasing driver safety.
