Jaltest Marine (Inboard) Readout Device

The Jaltest Marine module is a leading multi-brand and multi-system diagnostic platform specifically designed for the complex electronics of inboard engines , 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 support within a single, user-friendly environment. The platform supports technicians throughout the entire diagnostic and repair process – from analyzing faults in engine, propulsion, or charging systems to calibration after component replacement . This makes Jaltest Marine an essential tool for any professional marine 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 onboard electronic systems. These features enable quick troubleshooting and targeted resolution.

• Read and clear fault codes: Detects active, inactive, and permanent fault codes with clear descriptions and original fault code references. After performing a repair, the fault codes can be cleared immediately.
• Live data monitoring: Displays real-time sensor values ​​and system parameters such as engine speed , boost pressure , oil pressure , coolant or transmission temperature , and more. Users can create a custom 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 field conditions.
• System and ECU Information: Provides access to all ECU identification data including part number , serial number , software version and total operating hours , essential for maintenance management and warranty analysis.

Maintenance, service & calibration functions:

The Jaltest Marine module offers a wide and comprehensive range of maintenance, service, and calibration procedures for inboard engines , sterndrives, and marine generators . These features are equivalent to—or even more advanced than—those of the original dealer equipment, enabling technicians to carry out complete repairs independently and correctly .

Engine maintenance and service:

• Oil and Service Interval Reset: Resets the maintenance indicator in the ECU after an oil change or scheduled service based on operating 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 levels 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 you to adjust the idle speed 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 Steering Calibration: Calibration of electronic controls such as joysticks , including systems like Volvo Penta IPS , for precise and direct vessel control .
• Transmission Calibration: Resets and adjusts electronically controlled transmissions and clutches for smooth shifting and correct torque management.
• Sensor Calibration: 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.
• Engine Parameter Reset: Restores the ECU's adaptive learning values ​​to factory settings, for example after major repairs or system errors.
• Fuel System Bleeding: Starting procedure to remove air from the fuel system after replacing filters or when restarting after running out of fuel.

Advanced diagnostics & 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 fully-fledged technical partner for the professional marine workshop .

• Interactive wiring 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:
  • Connector pinouts
  • Test procedures for specific components
  • Component photos and location descriptions
  • Nominal measured values ​​(resistance, voltage, etc.)
• Engine technical data: Jaltest contains a comprehensive digital encyclopedia of engine-specific information, including:
  • Tightening torques for components such as spark plugs, cylinder heads and exhaust flanges
  • Adjustment data for valve clearance, ignition timing or idle speed, among other things.
  • 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: In the event of a fault code, Jaltest generates a step-by-step repair guide , including wiring checks , component tests and proposed solutions , tailored to the specific engine model.
• Symptom-based diagnosis: Without trouble codes, diagnosis can be initiated based on symptoms such as "engine won't start," "black smoke," or "vibrations." Jaltest guides the technician through a guided test procedure with logical checks.
• Technical Bulletins & Procedures: Access technical bulletins published 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 precise tasks per interval, such as replacing impellers, filters, V-belts, anodes , and other wear parts.
• Service Procedures: Detailed, step-by-step instructions for performing periodic maintenance, including a list of required parts, quantities, tightening torques, 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 enhance diagnostic capabilities, workshop organization, and technical support . 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 for each vessel .
