Jaltest AGV (Agricultural) Diagnostic Tool

The Jaltest AGV (Agricultural) is a leading multi-brand and multi-system diagnostic platform, developed for the complex electronics of modern agricultural vehicles. The system supports a wide range of machines, including tractors, harvesters, combine harvesters, self-propelled sprayers, and other agricultural vehicles. The solution consists of the robust, wireless Jaltest Link VCI (Vehicle Communication Interface) and the powerful Jaltest SOFT AGV diagnostic software.

What sets Jaltest apart is the direct integration of diagnostics, technical documentation, and repair guidance within a single platform. The technician is actively supported at every step of the process – from identifying engine, hydraulic, or electronic faults to post-repair calibration – all within a user-friendly and clear interface. Jaltest AGV is therefore the ideal partner for any workshop working with agricultural equipment from multiple brands.

Diagnostic functions:

The Jaltest AGV module offers comprehensive, brand-independent OE-level diagnostics for all electronic and hydraulic systems in modern agricultural vehicles. This allows technicians to quickly detect, analyze, and resolve faults.

• Reading and clearing fault codes: Detects active, inactive, and permanent fault codes and displays clear fault descriptions. After performing a repair, the fault codes can be cleared immediately.
• Live data monitoring: Real-time display of sensor values and system parameters such as hydraulic pressure, engine speed, turbo pressure, temperatures, and more. The user can create custom monitoring lists and display them numerically, as gauges, or via interactive charts.
• Testing actuators: Allows direct control of components such as hydraulic valves, proportional valves, and engine speed controllers to verify their correct operation during diagnosis.
• System and ECU information: Provides access to important identification data of control modules, such as part number, software version, serial number, and installation data.

Maintenance, service & calibration functions:

The Jaltest AGV module offers a comprehensive and in-depth package of maintenance, service, and calibration procedures for agricultural vehicles such as tractors, harvesters, and self-propelled sprayers. These functions are equivalent to – and in many cases more advanced than – those of original dealer diagnostic tools, enabling technicians to perform complete diagnostic and repair tasks independently.

Engine and exhaust gas aftertreatment:

• DPF service: Support for the diesel particulate filter (DPF), including forced regeneration, resetting soot and ash values, and checking back pressure sensors.
• AdBlue (SCR) system service: Complete diagnosis of the SCR system, including system reset, leak test, checking pump pressure, and control of AdBlue components.
• Injector coding: Learning the unique calibration codes (IMA / C2i / C3i) of new or refurbished injectors in the ECU.
• Engine system checks: Guided tests such as cylinder deactivation, compression test, and turbocharger check (VGT).
• EGR learning: Calibration of the exhaust gas recirculation valve (EGR) after cleaning or replacement.
• Oil service reset: Resetting the maintenance indicator after oil change or scheduled service based on operating hours.

Transmission and drive:

• Transmission calibration: Calibration for various transmission types (hydrostatic, powershift, CVT) for optimal operation after service.
• Clutch learning: Automatic learning procedure of the engagement point of the clutch.
• Drive parameters: Setting parameters such as throttle response and creep speed.

Hydraulic system:

• Hydraulic calibrations: Accurate calibration of:
  • Proportional valves for lift, boom, and auxiliary functions
  • Joysticks and control levers
  • Angle, length, and pressure sensors
  • System pressures and flow settings
• Active hydraulic tests: Direct control of hydraulic valves, pumps, and actuators to verify their operation and locate faults.

Specific agricultural functions:

• Lift calibration (front and rear): Setting lift height, descent speed, pull force control, and dynamic behavior.
• ISOBUS tool diagnosis: Reading, identifying, and configuring ISOBUS-compatible tools via the tractor.
• GPS / steering automation: Diagnosis and calibration of automatic steering systems and associated sensors.
• Braking systems and chassis functions: Maintenance and diagnosis of electronic and hydraulic brakes.
• Suspended front axle: Calibration and adjustment for comfort and stability.
• Steering calibration: Learning of steering angle sensors, including support for four-wheel steering.

Advanced diagnostics & technical information:

The strength of the Jaltest AGV module lies in the direct integration of specialized technical information within the diagnostic software. This transforms the platform from an error code reader to a full-fledged technical workshop partner for agricultural mechanization companies.

• Interactive hydraulic and electrical diagrams: Fully clickable diagrams where components such as pumps, valves, sensors, fuses, and wiring are dynamically displayed. Available per element:
  • Function and operation of the component
  • Test procedures and nominal measurement values
  • Component photos and location descriptions
  • Pin-outs of connectors
• Machine technical data: Jaltest includes comprehensive, vehicle-specific documentation per brand and model, including:
  • Tightening torques for engine and chassis components
  • Hydraulic specifications, such as pressure ranges, flow rates, and adjustment data
  • Fluid specifications for hydraulic oil, engine oil, coolant, and fuel
  • Component data from pressure sensors, proportional valves, and ECUs
• Repair guides by error code: When reading an error code, Jaltest generates a step-by-step repair guide, including wiring inspection, component testing, and targeted solutions, tailored to machine and brand.
• Symptom-based diagnosis: In the absence of error codes, faults can be investigated based on complaints, such as “no hydraulic pressure” or “engine stalls under load”, using a guided diagnostic logic.
• Technical bulletins and procedures: Direct access to technical bulletins issued by Jaltest regarding known failures, recurring issues, and repair procedures per AGV brand or type.
• Maintenance data: Automatically generated manufacturer-specific maintenance schedules based on operating hours, including detailed instructions for replacement timings and checks.
• Service procedures: Fully developed step-by-step work instructions for performing periodic maintenance tasks, including parts lists, fluid quantities, and adjustment values.

Specialized software modules:

The Jaltest AGV module is part of a modular platform and can be expanded with specialized software modules that elevate the functionality, diagnostic capabilities, and workshop organization to a higher level. These extensions are fully integrated into the Jaltest diagnostic environment and aimed at professional use in the agricultural sector.

• Jaltest GRP (Garage Resource Planning): A fully integrated workshop management system that allows users to centrally manage customer management, vehicle registration, work order scheduling, and invoicing. Diagnostic reports are automatically linked to the correct work order, resulting in a complete digital maintenance history per vehicle.
• Jaltest Info Online: A comprehensive technical knowledge base, continuously updated by the manufacturer. This module provides direct access to:
  • Fault code explanations
  • Electrical and hydraulic diagrams
  • Repair manuals
  • Component locations and connection data
  • Technical bulletins by vehicle type

• Jaltest ETM (Electronic Test Module): In combination with the optional ETM hardware, electronic components outside the vehicle can be tested, such as:
  • Pressure and position sensors
  • Electronic valves and actuators
  • Joysticks and control modules
  • Actuators and switches
