Modern vehicle diagnostics goes far beyond reading and clearing fault codes. After identifying and repairing a problem, technicians may also need to calibrate a sensor, configure a replacement component or adjust a supported ECU parameter.
This is where Jaltest Expert Mode comes in.
Expert Mode provides technicians with access to advanced diagnostic functions across supported vehicles and machinery. But what does it actually allow you to do, and when are these functions useful?
What Is Jaltest Expert Mode?
Jaltest Expert Mode allows technicians to carry out advanced diagnostic procedures that can modify parameters within supported electronic control units (ECUs).
Depending on the vehicle and system, this can include:
- Sensor and actuator calibrations
- Parameter adjustments and configurations
- Injector coding
- ECU replacement procedures
- Maintenance schedule settings
- DPF regeneration and replacement procedures
- Other manufacturer-specific functions
Because these procedures can change ECU settings, Jaltest displays an additional warning before an Expert Mode function is performed.
The exact functions available vary by manufacturer, model and ECU, so technicians should always check the latest Jaltest coverage for the vehicle being diagnosed.
What Is a Jaltest Calibration?
A Jaltest calibration allows a technician to recalibrate or teach a supported component or system after repair or replacement.
Replacing a component does not always complete the job. The vehicle’s ECU may need to learn the position, operating range or characteristics of the replacement part.
Depending on the system, Jaltest calibration procedures can be available for components such as sensors, actuators, injectors and variable geometry turbochargers.
For example, after replacing an accelerator position sensor, the ECU may need to learn its correct operating range. Where supported, Jaltest can provide the necessary calibration procedure.
This allows workshops to go beyond simply identifying the fault and complete more of the repair process themselves.
What Is Jaltest Parameter Adjustment?
Jaltest parameter adjustment allows technicians to modify configurable settings within supported ECUs.
The available parameters depend on the manufacturer, vehicle and electronic system.
A common example is injector replacement. On compatible diesel engines, information relating to a replacement injector may need to be entered into the ECU before the repair is complete.
Expert Mode can also provide access to maintenance schedule settings, ECU replacement procedures and other system configurations.
Importantly, parameter adjustment should not be confused with engine remapping. Jaltest Expert Mode is designed for supported diagnostic, repair and configuration procedures rather than performance tuning.
Practical Uses for Jaltest Expert Mode
The value of Expert Mode becomes clearer when looking at real workshop situations.
A technician could diagnose a fault using Jaltest, examine live data and wiring diagrams, replace the faulty component and then use Expert Mode to carry out the required calibration or configuration.
Another common example involves diesel particulate filters. On supported vehicles, Jaltest can perform DPF regeneration and procedures associated with DPF replacement.
If an ECU has been replaced, Expert Mode may also provide the necessary configuration procedure to help integrate the replacement unit correctly.
This makes Jaltest much more than a fault-code reader. It can support technicians from the initial diagnosis through to the final stages of a repair.

Which Vehicles Support Jaltest Expert Mode?
Expert Mode functionality is available across multiple Jaltest modules, including commercial vehicles, agricultural machinery, off-highway equipment, material handling equipment and marine applications.
However, not every advanced function is available on every vehicle.
Technicians should check the relevant coverage before beginning work to establish which calibrations, configurations and parameter adjustments are supported.

Why Buy Jaltest Diagnostics Through Eclipse?
Eclipse Automotive Technology is the UK’s official distributor and partner for Jaltest diagnostics, with a partnership dating back to 2010.
Buying through Eclipse means workshops receive more than the diagnostic hardware and software alone.
Current Eclipse Jaltest packages include handover training and 12 months of vehicle and IT technical support, alongside software updates and warranty.
Eclipse’s UK-based support team includes experienced vehicle technicians and IT specialists who can assist with diagnostic procedures, fault-code troubleshooting and software-related problems.
Customers using compatible Eclipse Testpad systems can also benefit from Eclipse Assist, which allows the technical support team to remotely access the system, with permission, to help investigate problems.
Eclipse also provides dedicated Jaltest diagnostic training courses for technicians looking to develop their diagnostic knowledge further.
Take Jaltest Diagnostics Further
Jaltest Expert Mode gives technicians the ability to go beyond fault-code reading and perform advanced procedures required during modern vehicle repairs.
From Jaltest calibration and parameter adjustment to ECU configuration, injector coding and DPF procedures, these functions can help independent workshops complete more work in-house.
Combined with Jaltest’s multi-brand coverage and Eclipse’s UK-based training and technical support, it provides workshops with a complete diagnostic solution rather than simply a fault-code reader.
