Jaltest Sweepers Diagnostic Tool

The Jaltest OHW reading module for sweepers is an advanced multi-brand diagnostic platform specially designed for industrial vehicles such as street sweepers and sweepers from, among others, Hako, Schmidt, Boschung, Ravo, Karcher, and Bucher. The system combines the robust Jaltest Link VCI with the powerful Jaltest SOFT OHW diagnostic software, tailored to the specific needs of vehicles with hydraulic, electric, and mechanical subsystems.

Jaltest OHW not only provides access to fault codes and live data but forms a complete solution for fault diagnosis, maintenance, calibration and system management. The intuitive software environment supports technicians in locating and resolving defects in engines, hydraulics, transmission, CAN networks, AdBlue systems, and other essential subsystems used in modern sweepers.

Diagnostic functions:

The Jaltest OHW module for sweepers offers comprehensive OE-level diagnostics for all electronic and hydraulic subsystems found in modern street sweepers. This enables technicians to quickly and accurately locate faults and take targeted action.

• Reading and clearing fault codes: Detects active, inactive, and permanent fault codes with clear descriptions and original OEM references. Fault codes can be cleared after repair.
• Live data monitoring: Real-time display of sensor values and parameters such as engine speed, hydraulic pressure, temperatures, brush motor speed, fuel consumption and more. Values can be displayed numerically, graphically, or in customized views.
• Testing actuators: Enables controlling individual components such as hydraulic valves, brush motors, pumps, fuel systems, fans or sensors to check their operation.
• System and ECU information: Provides direct access to identification data of control units such as part number, software version, serial number, and operating hours, including communication status and network position (e.g., CAN).

Maintenance, service, and calibration functions:

The Jaltest OHW module for sweepers offers an exceptionally broad and in-depth range of maintenance, service, and calibration functions, tailored to the systems of modern street sweepers. These functions are equivalent to – and often even more advanced than – those of original dealer diagnostic equipment. They enable technicians to independently resolve complex faults and perform complete service operations within a single diagnostic environment.

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 backpressure sensors.
• SCR/AdBlue system service: performs system resets, checks pump pressure, performs leak tests, and tests AdBlue pump, injector, and heater.
• Injector coding: encodes IMA, C2i, or C3i injectors in the ECU for precise 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 drivetrain:

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

Hydraulic system functions:

• Hydraulic calibrations: 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 lifting height, lowering speed, traction force, and response speed.
• GPS and steering automation: diagnosis and calibration of automatic vehicle guidance systems.
• 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 the Jaltest OHW module for sweepers lies in the direct integration of specialized technical information within the diagnostic software. This makes the platform not only a fault code reader but a full-fledged technical workshop partner for the maintenance and repair of modern street sweepers and multifunctional cleaning vehicles.

• 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:

  • Torque settings for engine and chassis components
  • Hydraulic specifications, such as system pressures, flow values, 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 manual 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 dates: 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, including parts, specifications, and actions.

Specialized software modules:

The Jaltest platform is modular and can be expanded with additional software modules that significantly increase 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.

Supported vehicle brands:

• Multifunctional vehicles: Aebi, ASH, Ausa, Bobcat, Boschung, Bucher, CMAR, Dulevo, Elgin, Eurovoirie, Hako, Hansa, Johnston, Kärcher, Ladog, Lindner, Macro Clean, Mathieu-YNO, Multicar, Nilfisk, Piaggio, Piquersa, Ravo, Reform, Scarab, Schmidt, Tenax
