Before going into the intricacies of the Jaltest Tractor diagnostic tool and its functioning, let us first understand what a typical tractor scan tool is.
For anyone in the agriculture or construction business, a tractor that is out of action is wasting money for every minute of downtime. Any malfunction has to be immediately diagnosed and rectified to get the tractor back on the job at the earliest. In traditional scenarios, it involved an elaborate process of calling service engineers who would diagnose the issue and carry out the required fixes. This would take days at conservative estimates.
All that has changed now with the advent of onboard computers and tractor diagnostic scanners. All modern equipment and vehicles including tractors are today armed with an onboard computer with the display unit usually tucked away below the dashboard on the driver’s side.
When any issue with the tractor arises a fault code in alpha-numeric format flashes on the display screen, indicating what the problem is. Now, instead of the service engineers, the Jaltest tractor diagnostics tool comes into the picture. Simply connect your software laptop to the onboard computer and you get details and interpretations of the fault codes, what the issue is all about, and the rectification action to be taken.
You therefore save a lot of money and time when you use the tractor diagnostic tool. You do not have to spend on paying for service engineers as the fault clearance is done on your premises only. Further, you save time and can quickly get your tractor back where it is needed the most, the farms or construction projects.

The Scope and Function Of The Jaltest Tractor Scan Tool
The Jaltest tractor diagnostics tool kit is a comprehensive and user-friendly software that is essential on farms and construction projects to read fault codes. Any type of equipment including tractors with electronic systems can be fixed using our tractor diagnostic software.
How to make repairs and fix problems are built into the software using the procedures set by the original equipment manufacturer. While looking for solutions, you have troubleshooting options, regardless of whether it is a simple matter like a loose wire or a more complex issue such as performing forced regens.
While the Jaltest tractor diagnostics scans various makes of tractors, it also seamlessly connects to other types of agricultural equipment such as harvesters, combines, balers, swathers, sprayers, and more. This tractor diagnostic software covers almost 120 different agricultural equipment brands including John Deere, Case IH, New Holland, Kubota, Challenger, Volvo, Caterpillar, and others.
Our Jaltest tractor diagnostic tool is not merely a fault code reader but also carries out advanced diagnostic possibilities. Use the diagnostic menu to navigate various functionalities such as bi-directional controls, code injectors, DPF regens, transmission calibration, rear lift & spool valves, and more. Not only that, you get live technical and maintenance information in a step-by-step guide format that will help you to rectify issues before any issue becomes a full-blown problem.
What is also special is that you get complete wiring diagrams to accurately pinpoint the source of the malfunction in the system. This greatly helps to clear the fault either through the system or by repair and replacement of components. With our tractor diagnostic software, you are always in control of your tractors to get the most out of them.
A cutting-edge benefit of the tractor scan tool is that it is versatile and provides diagnostics across multiple brands on the full range of agricultural and other equipment such as cranes, diggers, and of course tractors.
With wide-ranging technical innovations being implemented in tractors and other AGVs and the introduction of the latest engines with onboard computers, there has been in the near past, a rise in demand for software that can quickly diagnose faults and have them cleared. This space has been more than adequately filled by the Jaltest tractor diagnostic maintenance software.
Let us now analyze some of the benefits that the Jaltest tractor scan tool brings to the table.
ü Component Actuation: Interaction and actuation of various systems that include cylinder cutouts, fan activation, compression test, and checking of various mechanisms.
ü Intuitive and user-friendly tool: You get all the information on connectors as the tractor diagnostic software guides you on which connector to use and the OBD socket location in the vehicle.
ü Diagnosis and clearing fault codes: Finding, interpreting, diagnosing, and rectifying all errors that are registered on the Electronic Control Unit of the tractor.
ü Measuring values: The Jaltest tractor diagnostic tool has the capability to measure and display up to 8 values simultaneously. This helps to clear faults on a wide scale.
ü Calibrating and setting parameters: You can use the Jaltest to calibrate and set parameters of different functions and systems of your tractor that will be better suited to the work being done over factory settings. Access to calibration and parameter setting can be strictly controlled through passwords.
These are some of the functions and scope of the Jaltest tractor diagnostic scanner.

Full System Scans Vs. Scans By Symptoms
Jaltest tractor diagnostics offers several options for tractor maintenance. Typically, owners prefer to have a periodical routine for full system scans that include all key components and systems such as the engines, transmissions, brakes, hitch, and more.
In this activity, all systems are scanned for any malfunction or temporary fault codes that might be minor but have the possibility of becoming full-blown problems if left unattended.
Generally, the fault codes that crop up in routine full system scans are temporary and go away within a few driving cycles. However, care must be taken when this preventive maintenance is not enough, and more in-depth action needs to be taken. This is where you must initiate scans by symptoms for more permanent fault codes.
In this case, the tractor diagnostic will guide you on the particulars of the fault codes and the action to be taken, specific to that symptom only. This covers all components and symptoms and your tractor will soon be back on the job again.
It is always advisable to carry out full system fault prevention and identification scans at regular intervals so that no minor fault not generally detected in driving cycles remains unresolved for long.
Force Regens With The Jaltest Tractor Diagnostic Tool
A very critical and important activity that is performed with the tractor scan tool is force regens, specifically for diesel-powered tractors only. All diesel engines that have a stop-go-stop routine tend to accumulate soot in the diesel particulate filters. When passive regens are unable to control the accumulation, the tractor engine will seize up and the machine will go into limp mode.
It is here that the tractor diagnostic software performs forced regens to clear the accumulated soot in the diesel particulate filter. The process is as follows. The engine is switched on and runs for around 40 minutes at a rev that is automatically calculated by the Jaltest scan tool. At this rev, the temperature of the emission gasses rises sufficiently to burn the accumulated soot off.
This phenomenon is typically not seen in diesel engines that run constantly over long distances.
Examples of Tractor Fault Codes
Here are some tractor fault codes specific to New Holland and Case IH tractors. Please note that these fault codes are not standardized across makes and models of tractors.
