Diagnostik Fonksiyonlar ve Yetenekler
When used with Jaltest Diagnostics software, Jaltest Link Kit offers the following comprehensive diagnostic functions:
Fault Code Reading and Clearing (DTC Management)
On all supported vehicle brands you can read active and historic fault codes (DTC), view detailed descriptions and clear them when needed. Thanks to the Jaltest database, fault codes are shown not only as code numbers but together with detailed descriptions and possible causes.
Live Data Monitoring (Live Data / Parameters)
You can monitor engine speed, temperature, pressure, speed, fuel consumption, exhaust gas values, turbo pressure and hundreds more parameters in real time. Data is shown in graph and numeric formats and comparative analysis can be performed.
Actuator Tests (Component Activation)
You can test injectors, EGR valve, VGT turbo, fan clutch, cooling fan, AdBlue pump, retarder, A/C compressor and other components individually or together. It is the most effective way to quickly identify a faulty part.
Calibration and Adjustment Procedures
Injector calibration (IMA/IQA codes), turbo adaptation, starting DPF regeneration, SCR system calibration, transmission adaptation, steering angle calibration and many more adjustment procedures.
Programming and Configuration
Changing ECU parameters, editing vehicle configuration, speed limiter settings, PTO (power take-off) configuration, headlamp settings, instrument cluster configuration and more.
Guided Diagnostics (Guided Diagnostics / GRP)
One of Jaltest’s most unique features, Guided Repair Process (GRP), guides the technician step by step on complex faults. When you enter a symptom (for example "engine power loss"), the software analyzes possible causes and directs you toward the most likely solution. It shows the points you need to measure, provides reference values and determines the next step based on the result.
Wiring Diagrams and Component Locations
You can access detailed electrical wiring diagrams, connector pinouts, component layout diagrams and repair instructions for every vehicle brand and model directly from the software.
