Jaltest Diagnostics

Multi-brand diagnostics tool

Jaltest Diagnostics is a universal diagnostics tool, that provides insight in the failures and maintenance needs of every (heavy duty) vehicle or machine, regardless of the brand or model. The system collects vehicle information based on which it makes a diagnosis of the vehicle status, errors, maintenance needs and service indications. It helps you to locate malfunctions, find its cause(s), and fix the issue(s). For this, Jaltest Diagnostics offers manuals, instruction sheets, pictures, drawings, and all the needed technical information.


The Jaltest Diagnostics system includes some outstanding features:

Modular diagnostics solution

The Jaltest Diagnostics kits consist of a communication interface device, software license specific for the type of vehicles covered, and a selection of connection cables.

Highly customizable system

When you need more than one modular kit you can configure your own diagnostic equipment. You can combine multiple software licenses and extend the selection of connection cables to cover all required vehicles, machines, etc.

User friendly interface

Jaltest Diagnostics has a very user-friendly interface, that makes it easy to operate the system and navigate quickly. The system is specially developed to carry out the most advanced tasks of diagnostics and maintenance in a simple and intuitive manner. The interface is also highly customizable, so that the most important information for you is always visible at a glance. In addition, the responsive design allows for easy control from various devices.

Guided diagnostics

Jaltest Diagnostics provides all necessary information to repair vehicle breakdowns in an easy and effective way. The diagnostic software offers technical information, component information and location, system wiring diagrams, and easy to follow step-by-step troubleshooting guides.

Always up-to-date

The Jaltest Diagnostics software is updated at least three times a year, adding new brands, models and systems, and innovative features. This makes that the system is always up to date and you always have the most recent information at hand.

Reduction of repair time

The wide coverage of the Jaltest Diagnostics software and the guided diagnostics will help you to find and repair errors in the fastest way possible.


The Jaltest Data-Link is a very compact and lightweight communication interface, making it easy to move and take with you. The system offers very fast connection speed and first-class communication options. In addition, the Link-device is very robust, shockproof, and resistant to dirt and water. This makes it very suitable for intensive use in workshops.

Additional modules

Jaltest Diagnostics also offers additional diagnosis modules, making it a very complete diagnosis tool:


The Electronic Test Module (ETM) can be used to verify installed electronic modules and sensors. With this module you can check if a component is damaged, or if an error is caused by other elements, like wiring, control unit, etc. This avoids the faulty replacement of a component, while the problem is actually caused by another component. The ETM module is available for commercial vehicles, as well as agricultural machinery, construction machinery, and vessels.


With the Garage Resource Planning (GRP) module you can organize and manage your daily activity in an agile way. The workshop management software consolidates information about customers, vehicles and reports, efficiently distributes the workload, and can access the whole database from anywhere at any time. The GRP module offers multiple modes, which makes it suitable for small, medium, and large workshops.
