Jaltest OHW (Off-Highway) Diagnostic Tool

The Jaltest OHW (Off-Highway) is a leading multi-brand and multi-system diagnostic platform, specifically developed for the complex world of earthmoving machines, agricultural vehicles, stationary engines, and special vehicles. The system consists of a combination of the robust wireless Jaltest Link VCI (Vehicle Communication Interface) and the powerful Jaltest SOFT OHW diagnostic software.

The philosophy of Jaltest is based on the integration of diagnosis, technical information, and repair guidance in one platform. The technician is guided step by step in troubleshooting engine, hydraulic, and electronic systems, including post-repair calibrations, all within one clear and user-friendly interface.

Diagnostic functions:

Jaltest OHW offers comprehensive, brand-independent OE-level diagnostics for all relevant systems within off-highway vehicles, including engine, hydraulic, and electronic systems:

• Reading and clearing fault codes: Detects active, inactive, and permanent faults and provides the option to clear fault codes after repair.
• Live data monitoring: Displays real-time sensor values and system parameters such as hydraulic pressure, engine speed, and turbo pressure. Users can create their own monitoring list. Values are displayed in numeric form, gauges, or interactive graphs.
• Testing actuators: Allows direct control of components such as hydraulic valves, proportional valves, and engine speed controllers to monitor their operation in real time.
• System and ECU information: Provides access to important identification data of electronic control units such as part numbers, serial numbers, and software versions.

Maintenance, service, and calibration functions:

The Jaltest OHW (Off-Highway) module offers an exceptionally wide and in-depth range of maintenance, service, and calibration functions for earthmoving machines, agricultural vehicles and stationary engines. These functions are equivalent to or more extensive than dealer diagnostic equipment and enable the independent resolution of complex faults.

Engine and exhaust gas aftertreatment:

• DPF service: supports static and dynamic regeneration of the particulate filter, including reset of soot and ash values and checking back pressure sensors.
• SCR/AdBlue system service: performs system resets, checks pump pressure, conducts leak tests, and tests AdBlue pump, injector, and heating.
• Injector coding: codes IMA, C2i, or C3i injectors in the ECU for accurate fuel injection.
• Engine condition tests: includes cylinder deactivation, compression tests, and variable turbo control (VGT).
• EGR learning: calibrates the EGR valve after maintenance for correct emission and combustion values.

Transmission and driveline:

• Transmission calibration: supports hydrostatic, powershift, and CVT transmissions with adjustment after repair or component replacement.
• Clutch learning: determines the engagement point of the clutch via a guided learning procedure.
• Drive parameters: sets crawl speed, pedal response, and traction parameters.

Hydraulic system functions:

• Hydraulic calibration: calibration of proportional valves, joysticks, angle, length, and pressure sensors on mast/boom.
• Pressure and flow settings: sets maximum working pressures and hydraulic flow rates.
• Active hydraulic tests: directly controls valves and pumps to quickly locate component failures.

Specific agricultural and earthmoving functions:

• Lifting device calibration: adjustment of lift height, descent speed, pulling force, and response speed.
• GPS and steering automation: diagnosis and calibration of systems for automatic vehicle guidance.
• Chassis and brake systems: maintenance and calibration of hydraulic and electronic brake components.
• Suspended front axle: calibration of spring systems for comfort and stability on rough terrain.

Advanced diagnosis & technical information:

The true power of Jaltest OHW lies in the direct integration of specialized technical information into the diagnostic software. This makes the platform not just a scanner, but a full-fledged technical workshop partner for agricultural and earthmoving applications.

• Interactive hydraulic and electrical diagrams: Fully dynamic diagrams where components such as pumps, valves, and sensors, as well as fuses and wiring, are clickable. Each click immediately shows related information such as:

  • Function and operation of the component
  • Test procedures and nominal measurement values
  • Component photos and location descriptions
  • Pin-outs of connectors

• Machine technical data: Access to an extensive database with specific machine documentation, including:

  • Tightening torques for engine and chassis components
  • Hydraulic specifications, such as system pressures, flow rates, and adjustment data
  • Fluid specifications for hydraulic oil, engine oil, coolant, and more
  • Component data with technical characteristics of, for example, pressure sensors, proportional valves, and all relevant ECUs
• Repair guides per fault code: For each fault code, a step-by-step guide is provided with wiring checks, component and line tests, and specific solutions per brand and model.
• Symptom-based diagnosis: For complaints such as "no hydraulic pressure" or "engine stalls under load", guided diagnoses can be performed, even without present fault codes.
• Technical bulletins and procedures: Direct access to Jaltest information on recurring faults, common repairs, and brand-specific instructions.
• Maintenance data: Automatically generated maintenance schedules based on operating hours, including specified tasks, replacement intervals, and parts lists.
• Service procedures: Clear instructions for periodic maintenance, tailored to machine type, specifying parts, specifications, and actions.

Specialized software modules:

The Jaltest platform is modular and can be expanded with additional software modules that significantly enhance the functionality and efficiency of the diagnostic device:

• Jaltest GRP (Garage Resource Planning): An integrated workshop management system that offers functions for customer management, work order scheduling, quotation creation, repair history, and the automatic linking of diagnostic reports to the work order. Jaltest thus becomes a full-fledged CRM and workshop management platform.
• Jaltest ETM (Electronic Test Module): In combination with the optional ETM hardware, electronic components outside the vehicle can be tested. This is ideal for diagnosing parts such as ABS modulators, brake pedal sensors, pressure sensors, and speed sensors when there is doubt about their operation.
• Jaltest Info: Access to an extensive technical knowledge base with repair manuals, wiring diagrams, adjustment data, fault code explanations and technical bulletins, sorted by vehicle brand and machine type. This digital encyclopedia is fully integrated into the diagnostic environment.
