Linked guided diagnosis
With Jaltest, you don’t need to be an expert on every single brand; it gives you the possible causes of the fault and guides you through a step-by-step path of repair linking directly to the actions to be carried out (testing procedures, component replacement, etc).

Leading technical information
Jaltest is a clear winner when it comes to having the best technical information available. This includes step-by-step troubleshooting guides, interactive wiring diagrams, component locations, test values, system diagrams, vehicle technical data (OEM adjustment torques, reference measurements, parameters, diagrams, etc) and repair times.

Expert mode
Jaltest offers advanced diagnostics functionality for workshops under ‘Expert Mode’. When this mode is active, you will be able to carry out actions that require the modification of parameters in different ECUs, such as sensor and actuator calibration, configuration of operating parameters or DPF replacement and regeneration, among others.
