Jaltest Marine (Outboard) Diagnostic Tool

The Jaltest Marine is a leading multi-brand and multi-system diagnostic platform, specifically developed for the complex electronics of modern outboard motors. The system consists of two main components: the robust, waterproof and wireless Jaltest Link VCI (Vehicle Communication Interface) and the powerful Jaltest SOFT Marine diagnostic software.

The unique working method of Jaltest integrates diagnosis, technical information and repair guidance into one platform. It is not a simple fault code reader, but a complete workshop partner that guides the technician through the entire process: from fault analysis to calibration after repair – all within one intuitive and user-friendly interface. This makes Jaltest Marine an essential platform for every professional watersports workshop.

Diagnostic functions:

Jaltest Marine offers comprehensive OE-level diagnostics for all electronic systems in outboard motors and marine applications. The functions are designed for quick fault analysis and effective troubleshooting:

• Read and clear fault codes: Detects active, inactive and permanent fault codes with clear descriptions. Fault codes can be cleared immediately after the repair is performed.
• Live data monitoring: Displays real-time sensor values and system parameters, such as engine speed, coolant temperature, oil pressure, trim angle and fuel pressure. Users can create custom lists of parameters to monitor, displayed numerically or in interactive graphs.
• Actuator testing: Enables direct control of components such as injectors, the fuel pump, the trim/tilt motor and other relevant actuators, to verify their correct operation in real time.
• System and ECU information: Provides access to data from the control units, such as part numbers, serial numbers, software versions and the total number of operating hours – information essential for maintenance planning and warranty claims.

Maintenance, service & calibration functions:

Jaltest Marine offers a wide and comprehensive range of maintenance, service, and calibration functions essential for the professional upkeep of modern outboard motors. The available procedures often approach or exceed the level of official dealer diagnostic equipment.

Engine maintenance and service:

• Oil and service interval reset: Resets the maintenance indicator in the engine control unit (ECU) after oil change or a performed periodic service based on operating hours.
• Injector coding: Writes the injector calibration codes to the ECU for accurate fuel injection, optimal combustion and maximum engine power.
• Engine system checks: Performs guided system tests, including cylinder deactivation, to detect problems with injectors, spark plugs or compression.
• Idle speed adjustment: Provides the ability to adjust the idle speed within manufacturer specifications, for example for trolling use.

System calibrations:

• Throttle position sensor (TPS) calibration: Calibrates the throttle position sensor for correct throttle response and stable engine dynamics.
• Trim/tilt sensor calibration: Resets the trim and tilt angle sensor for an accurate instrument display.
• Oil pressure and temperature sensors: Calibrates these critical engine sensors for reliable measurements and fault-free operation.

General service procedures:

• Winterizing & preservation: Starts an automated process to properly prepare the engine for winter storage, including flushing with fuel preservative.
• Bleeding the fuel system: Helps remove air from the fuel system after maintenance on filters or lines.
• Reset of engine parameters: Restores the adaptive learning values of the ECU to factory settings, which is useful after certain overhauls or fault conditions.

Advanced diagnosis & technical information:

The strength of Jaltest Marine lies in the direct integration of specialized technical information into the diagnostic software. This allows the system to evolve from a fault code reader to a complete technical partner for the watersports workshop.

• Interactive electrical diagrams: Fully clickable electrical diagrams of the engine system. Users can zoom in and click on components, fuses, ground connections, and wiring. For each element, the following are displayed:

  • Pin-outs of connectors
  • Test procedures for the specific component
  • Component photos and location descriptions
  • Nominal measurements (resistance, voltage, etc.)
• Engine technical data: Jaltest Marine includes a digital encyclopedia with all relevant engine specifications, including:
  • Torque settings for components such as spark plugs, cylinder head, and oil pan plug
  • Adjustment data for, among others, throttle cable, ignition timing, and idle speed
  • Fluid specifications such as type and amount of engine oil, lower unit oil, and coolant
  • Component data with characteristics of sensors, actuators, and ECUs
• Repair guides per fault code: Each fault code is linked to a step-by-step repair manual, including wiring checks, component tests, and specific solutions per engine model.
• Symptom-based diagnosis: In the absence of fault codes, diagnosis can be performed based on complaints, such as “engine does not start”, “overheating at low RPM”, or “power loss at full throttle”, with a guided test sequence for root cause identification.
• Technical bulletins and procedures: Access to technical bulletins issued by Jaltest, with information about technical bulletins, known failures, common defects, and repair advice for outboard motors.
• Maintenance data: Automatically generated manufacturer-specific maintenance schedules based on operating hours, including tasks such as replacement of impeller, spark plugs, filters, and anodes.
• Service procedures: Clear step-by-step instructions for performing the full service, including required parts, fluids, and adjustment data.

Specialized software modules & expansions:

Jaltest Marine is not just a diagnostic tool, but a modular ecosystem that can be expanded with specialized software modules. These expansions increase efficiency, accuracy, and professionalism within every modern watersports workshop.

Jaltest GRP (Garage Resource Planning):

A fully integrated workshop management and CRM system, enabling users to centrally and efficiently manage their daily processes:

• Customer and vessel management: Manage customer profiles and detailed vessel information, including engine configuration and maintenance history.
• Create and schedule work orders: Prepare digital work orders, schedule tasks per technician and keep an overview of workshop occupancy.
• Synchronize diagnosis: Automatically link diagnostic reports to work orders. This creates a complete administration with a full maintenance history per vessel.
• Billing and quotes: Generate quotes and invoices directly based on used parts and performed work.
