Jaltest Marine (Inboard) Diagnostic Tool

The Jaltest Marine module is a leading multi-brand and multi-system diagnostic platform, specifically developed for the complex electronics of inboard engines, stern drives (sterndrives) and marine generators. The system combines the robust, waterproof and wireless Jaltest Link VCI (Vehicle Communication Interface) with the powerful and comprehensive Jaltest SOFT Marine diagnostic software.

What sets Jaltest Marine apart is the integration of diagnostics, technical documentation, and repair guidance within a single user-friendly environment. The platform supports technicians throughout the entire diagnostic and repair process – from analyzing faults in engine, drive, or charging systems to calibration after component replacement. Jaltest Marine is thus an essential tool for every professional watersports workshop working with inboard systems and generator sets.

Diagnostic functions:

The Jaltest Marine module for inboard engines, sterndrives, and generators offers comprehensive OE-level diagnostics for all relevant electronic systems on board. These features enable quick detection and targeted resolution of malfunctions.

• Read and clear fault codes: Detects active, inactive, and permanent fault codes with clear descriptions and original fault code references. After a repair is performed, fault codes can be cleared immediately.
• Live data monitoring: Displays real-time sensor values and system parameters such as engine speed, turbo pressure, oil pressure, coolant or transmission temperature, and more. Users can create their own list of values to monitor, which can be displayed numerically or in interactive graphs.
• Actuator testing: Enables direct control of components such as injectors, the fuel pump, and various relays or solenoid valves, to verify their correct operation under real-world conditions.
• System and ECU information: Provides access to all ECU identification data, including part number, serial number, software version and the total running hours, essential for maintenance management and warranty analysis.

Maintenance, service & calibration functions:

The Jaltest Marine module offers a wide and in-depth range of maintenance, service and calibration procedures for inboard engines, sterndrives and marine generators. These functions are equivalent to – or more advanced than – those of original dealer equipment, enabling the technician to perform complete repairs independently and correctly.

Engine maintenance and service:

• Oil and service interval reset: Resets the maintenance indicator in the ECU after oil change or scheduled service based on running hours.
• Injector coding: Programs the calibration codes of new or remanufactured injectors for optimal fuel injection, combustion and power.
• DPF service: Provides full support for the diesel particulate filter (DPF), including forced regeneration, and reset of soot and ash values after filter cleaning or replacement.
• Engine system checks: Performs specific system tests such as cylinder deactivation, to check the contribution per cylinder and isolate problems with injectors, spark plugs or compression.
• Idle speed adjustment: Allows the idle speed to be adjusted within OEM limits, for example for fine-tuning generators or engines in trolling use.

System calibrations:

• Throttle position sensor (TPS) calibration: Calibration of the TPS sensor for correct throttle response and stable engine dynamics.
• Joystick and control calibration: Calibration of electronic control elements such as joysticks, including systems like Volvo Penta IPS, for precise and direct vessel control.
• Transmission calibration: Reset and adjustment of electronically controlled transmissions and clutches, for smooth shifting behavior and correct torque management.
• Calibrating sensors: Calibration of important engine sensors such as those for turbo pressure, oil pressure, coolant temperature and fuel pressure.

General service procedures:

• Winterizing & preservation: Guided procedure for winterizing the engine. Includes flushing the cooling system and preserving the fuel system, to prevent frost and deposit damage.
• Reset of engine parameters: Restores the adaptive learning values of the ECU to factory settings, for example after major repairs or system errors.
• Fuel system bleeding: Start procedure to remove air from the fuel system after filter replacement or when restarting after fuel depletion.

Advanced diagnosis & technical information:

The true power of the Jaltest Marine module lies in the direct integration of specialized technical information into the diagnostic software. This makes the system more than just a scanner – it becomes a full-fledged technical partner for the professional watersports workshop.

• Interactive electrical diagrams: Jaltest offers dynamic, clickable diagrams of the engine system and onboard electronics. Users can zoom in on components, fuses, ground connections, and wiring, with direct access to:
  • Pin-outs of connectors
  • Test procedures for specific components
  • Component photos and location descriptions
  • Nominal measurements (resistance, voltage, etc.)
• Engine technical data: Jaltest contains an extensive digital encyclopedia with engine-specific information, including:
  • Torque settings for parts such as spark plugs, cylinder heads, and exhaust flanges
  • Adjustment data for e.g. valve clearance, ignition timing, or idle speed
  • Fluid specifications for engine oil, coolant, transmission oil, and lubricants
  • Component data with technical specifications of sensors, actuators, and ECU functions
• Repair guides by fault code: When a fault code occurs, Jaltest generates a step-by-step repair manual, including wiring checks, component tests and proposed solutions, tailored to the specific engine model.
• Symptom-based diagnosis: Without fault codes, diagnosis can be started based on complaints such as “engine does not start”, “black smoke” or “vibrations”. Jaltest guides the technician through a guided test procedure with logical checks.
• Technical bulletins & procedures: Access to technical bulletins issued by Jaltest on common problems, recurring faults, and brand-specific maintenance recommendations.
• Maintenance data: Automatically generated, manufacturer-specific maintenance schedules, based on operating hours. The software specifies exact tasks per interval, such as replacement of impeller, filters, V-belts, anodes and other wear parts.
• Service procedures: Detailed, step-by-step instructions for performing periodic maintenance, including an overview of required parts, quantities, torque settings, and adjustment values.

Specialized software modules:

The Jaltest Marine module is part of a modular platform and can be expanded with specialized software modules that elevate diagnostic capability, workshop organization, and technical support to a higher level. These expansions are fully integrated into the Jaltest diagnostic environment and tailored for professional use within the maritime sector.

• Jaltest GRP (Garage Resource Planning): An integrated workshop management system that allows users to centrally manage customers, vessels, work orders, scheduling, and invoicing. Diagnostic reports are automatically linked to the correct work order, resulting in a fully digital maintenance history per vessel.
