Jaltest Marine (Jetski) Diagnostic Tool

The Jaltest Marine module for personal watercraft (PWC / Jet Skis) is a leading multi-brand and multi-system diagnostic platform, developed for the complex electronics of modern personal watercraft. 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.

Jaltest Marine integrates diagnostics, technical documentation, and repair guidance within a single clear environment. From reading fault codes to programming a new key, the software supports the technician at every step of the process. Thanks to support for brands such as Sea-Doo, Yamaha, Kawasaki, and other PWC manufacturers, Jaltest Marine is an indispensable partner for every professional watersports workshop specializing in jet skis.

Diagnostic functions:

The Jaltest Marine module for personal watercraft offers comprehensive OE-level diagnostics for all electronic systems in modern jet skis. This enables technicians to quickly and accurately diagnose and address faults.

• Reading and clearing fault codes: Detects active, inactive, and permanent fault codes with clear descriptions and original fault code references. After repair, fault codes can be cleared immediately.
• Live data monitoring: Displays real-time sensor values and system parameters, such as engine speed, intake air temperature, GPS speed, and steering angle. Values can be displayed numerically or graphically. Users can create their own monitoring lists.
• Testing actuators: Enables direct control of components such as injectors, the fuel pump, and systems like iBR (Intelligent Brake & Reverse) or RiDE to check correct operation.
• System and ECU information: Provides access to identification data of the control units, including part number, serial number, software version, and the total number of operating hours – essential for maintenance and warranty management.

Maintenance, service & calibration functions:

The Jaltest Marine module for personal watercraft (PWC / Jetskis) offers an exceptionally broad and in-depth package of maintenance, service, and calibration procedures. These functions are equivalent to – or even more advanced than – the capabilities of original dealer diagnostic equipment. They enable maintenance and repair work to be carried out completely independently and according to OE specifications.

Engine maintenance and service:

• Oil and service interval reset: Resets the maintenance indicator in the ECU after an oil change or service based on operating hours.
• Injector coding: Programs the calibration code of new injectors into the ECU for accurate fuel injection and optimal combustion.
• Engine system checks: Performing guided system tests, including cylinder shutdown, which checks for injection, ignition, or compression issues per cylinder.
• Idle speed adjustment: Adjusts the idle speed within factory specifications, for example for tuning after overhaul or for specific operating profile.

System calibrations and learning procedures:

• Key coding (D.E.S.S.): Programming of Digitally Encoded Security System (D.E.S.S.) keys for Sea-Doo. Including adding, removing, or modifying standard, learning, or rental keys.
• iBR / RiDE system calibration: Calibration of the intelligent brake and reverse system of Sea-Doo (iBR) or Yamaha (RiDE) after maintenance or replacement of components.
• Throttle position sensor (TPS) calibration: Calibration of the TPS sensor for correct throttle response and stable engine control.
• Steering calibration: Calibration of the steering angle sensor, necessary for correct steering function and display in combination with iBR.

General service procedures:

• Preparing for winter & preservation: Guided procedure for winter storage, including flushing the cooling system and preserving the fuel system, to prevent freezing and gum formation.
• Reset of engine parameters: Restores the adaptive learning values of the ECU to factory settings, useful after major repairs or reprogramming.

Advanced diagnostics & technical information:

The strength of the Jaltest Marine module for jetskis lies in the integration of specialized technical information into the diagnostic software. This makes the system a full-fledged technical workshop partner for any professional watersport workshop.

• Interactive electrical diagrams: Jaltest offers complete, dynamic diagrams of engine systems and onboard electronics. Users can zoom in and click on components, fuses, ground connections, and wiring. Available per part are:
  • Pin-outs of connectors
  • Test procedures
  • Component photos and location descriptions
  • Nominal measurement values (resistance, voltage, etc.)
• Jetski technical data: Jaltest contains a comprehensive digital knowledge base per jetski model, including:
  • Starting moments for e.g. spark plugs, cylinder heads, and engine mounts
  • Adjustment data for throttle cable, ignition timing, and idle speed
  • Fluid specifications for engine oil, transmission oil, coolant, and brake fluid
  • Component data with characteristics of sensors, actuators, and control modules
• Repair guides by fault code: For a fault code, Jaltest generates a step-by-step guide, including wiring checks, component tests, and targeted solutions by manufacturer and model.
• Symptom-based diagnosis: Without fault codes, a guided test procedure can be initiated based on complaints such as “won't start”, “iBR not working”, or “no power” with a logical cause sequence.
• Technical bulletins and procedures: Direct access to technical bulletins with information about common failures, service notifications, and model-specific repair advice.
• Maintenance data: Automatically generated maintenance schedules based on operating hours, including specific tasks such as replacing impellers, spark plugs, filters, and anodes.
• Service procedures: Clear step-by-step instructions for periodic maintenance, including parts lists, quantities, and adjustment values.

Specialized software modules:

The Jaltest Marine module is fully modular and can be expanded with specialized software modules that significantly improve the functionality, workshop organization, and testing capabilities. These expansions make the system particularly suitable for professional use in the maintenance sector for jet skis and PWCs.

• Jaltest GRP (Garage Resource Planning): An integrated workshop management and CRM system that allows users to centrally manage customers, vessels, work orders, and scheduling. Every diagnostic report generated with Jaltest Marine can be automatically linked to the corresponding work order for a fully digital maintenance history.
• Jaltest Info Online: A comprehensive technical knowledge base that provides access to fault code explanations, electrical schematics, component locations, adjustment data, and maintenance procedures, all linked to jetski models and engine types. This module is continuously updated and fully integrated into the Jaltest diagnostic environment.
• Expert Mode: An optional advanced feature that provides access to deep system configurations, such as calibrations, ECU programming, parameter settings, and advanced testing procedures, intended solely for professional use.
