The OBDSTAR N015A is a pass-through adapter connecting the 4-pin Honda OBD diagnostic connector on the engine side to a 16-pin OBD2 socket (J1962) on the scanner side. On the engine side, the adapter couples to the four-pin diagnostic connector of Honda outboard motors, typically located on or near the engine block.

Honda outboard motors do not feature a modern OBD2 port, but instead use a proprietary four-pin connector. The adapter comprises two separate plug components that connect together and establish the correct pin connections physically, including the K-line. This enables communication with the engine control unit of the marine motor; the adapter itself performs no signal processing or protocol conversion. The adapter simply makes the four-pin port accessible and does nothing further. What you can subsequently read out depends on the marine coverage in your own OBDSTAR scanner. The product information specifies no individual engine models or production years; only outboard motors with the 4-pin connector fall within the scope of application.

ADVANTAGES

Diagnostics on marine engines possible — Honda outboard motors with 4-pin OBD connector become accessible to an OBDSTAR diagnostic scanner.
Cable-free two-piece design — the two plug components connect directly together, providing a short connection in the confined space around the engine block.
K-line correctly routed — the relevant signal lines are secured to the correct pins, enabling connection to the Honda ECU.
No engine modification — the adapter uses the existing diagnostic connector; the outboard motor wiring remains unchanged.

CONSIDERATIONS

Works exclusively with OBDSTAR — the adapter is designed for OBDSTAR equipment; use with diagnostic scanners from other manufacturers is not supported.
Adds no additional coverage — the adapter does not expand your diagnostic capabilities. The marine software in your own scanner determines which engines and functions are available.
Outboard engines only — Honda cars and Honda motorcycles are not covered; they use a different diagnostic connector.
Passive pass-through — the adapter does not convert protocols. If your device does not support the engine's protocol, the adapter cannot resolve this.

Applications and functionality

When used with an OBDSTAR device that supports marine applications, the adapter provides access to the outboard engine management system.

Control units you can reach

  • Engine control unit (ECU): The boat engine ECU is accessed via the four-pin diagnostic connector and the K-line.
  • Additional systems: The product information lists no further control units on these engines; assume engine management only.

What you can do

  • Connect via the 4-pin port: Link the four-pin diagnostic connector to the 16-pin OBD2 input on your diagnostic cable.
  • ECU communication via K-line: Make the engine control unit's K-line available for the protocols your device supports.
  • Analyse fault codes: Read and evaluate error codes from the boat engine management system.
  • Monitor live data: Request sensor readings and engine parameters during operation, to the extent your device supports this for the engine.
  • Please note: The adapter performs no measurements and carries out no conversion; everything operates through the connected OBDSTAR device.

Compatible vehicles and applications

The determining factor is the 4-pin OBD diagnostic connector on the outboard engine, not the engine type. If there is a four-pin diagnostic connector on or near the engine block, this adapter will connect. Current product information does not provide a detailed list of engine models and production years.

Honda:

  • Outboard engines with 4-pin OBD connector: Consult the OBDSTAR compatibility list for specific engine models and production years.
💡
Good to know: The 4-pin diagnostic port on Honda outboard engines is typically located on or near the engine block; your engine manual specifies the exact location. Verify that the diagnostic connector on your engine has four pins before ordering.
