The OBDSTAR N015A is a connector adapter that bridges the 4-pin Honda OBD diagnostic connector on the engine side and a 16-pin OBD2 port (J1962) on the diagnostic tool side. On the engine side, the adapter connects to the four-pin diagnostic connector found on Honda outboard motors, typically located on or near the engine block.

Honda outboard motors don't have a modern OBD2 port—they use their own four-pin connector instead. The adapter consists of two separate plug components that connect to each other and establish the correct pin connections, including the K-line. This enables communication with the outboard engine's control unit; the adapter itself performs no signal processing or protocol conversion.

The adapter simply makes the four-pin port accessible and does nothing more. What you can read out afterward depends on the marine coverage in your own OBDSTAR diagnostic tool. The product information lists no specific engine models or model years—only outboard motors with the 4-pin connector fall within the scope of use.

KEY BENEFITS

Diagnose outboard engines — Honda outboard motors with 4-pin OBD connectors become accessible to an OBDSTAR diagnostic reader.
Cable-free two-piece design — the two plug components connect directly to each other, providing a short connection in the tight space around the engine block.
K-line correctly routed — the relevant signal lines are mapped to the correct pins, ensuring proper communication with the Honda ECU.
No engine modifications — the adapter uses the existing diagnostic connector; no changes are made to the outboard motor's wiring.

IMPORTANT NOTES

Works only with OBDSTAR — the adapter is designed for OBDSTAR equipment; use with diagnostic tools from other manufacturers is not supported.
No expanded coverage — the adapter doesn't extend your diagnostic capabilities. The marine software in your diagnostic tool determines which engines and functions are available.
Outboard motors only — Honda cars and Honda motorcycles are not supported; they use different diagnostic connectors.
Passive pass-through — the adapter performs no protocol conversion. If your tool doesn't support the engine's protocol, the adapter won't solve that.

Applications and Features

When paired with an OBDSTAR diagnostic tool that includes marine coverage, the adapter provides access to the outboard engine's management system.

Control units you can reach

  • Engine Control Unit (ECU): the outboard engine's ECU is accessed via the four-pin diagnostic connector and K-line.
  • Additional Systems: the product information does not list any further control units on these engines; assume engine management.

What You Can Do

  • Connecting to the 4-pin port: connect the four-pin diagnostic connector to the 16-pin OBD2 input of your diagnostic cable.
  • ECU Communication via K-line: make the K-line of the engine control unit available for the protocols your device supports.
  • Analyze Fault Codes: read and evaluate error codes from the outboard motor's engine management system.
  • Monitor Live Data: retrieve sensor values and engine parameters during operation, as far as your device supports for this engine.
  • Important: the adapter itself performs no measurements and carries out no conversion; everything runs through the connected OBDSTAR device.

Compatible Vehicles and Applications

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

Honda:

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