This adapter cable connects the 3-pin diagnostic connector of older Honda passenger cars to a diagnostic tool with a 16-pin OBD2 plug. The connector is usually located on the passenger side, under the dashboard compartment or near the centre console.

The 3-pin connector supplies power and earth and carries the K-line for diagnostics. This allows you to read, among other things, the engine management. Next to the 3-pin connector there is often a separate 2-pin plug. That is for flash codes and is not part of this cable. The cable physically converts the connector; the diagnostic tool itself must support the Honda protocol of this generation.

PROS

✔Provides access to the engine management of Honda models without a 16-pin connector.
✔The connector itself provides power; separate battery clips are not required.
✔You use your existing diagnostic tool with a 16-pin OBD2 plug; a separate brand-specific tester is not required.
✔The cable works passively: no software or settings are required.

POINTS TO NOTE

✕Your diagnostic tool must support Honda diagnostics via the 3-pin connector; the cable does not convert protocols.
✕A simple EOBD code reader does not work with this cable; it only reads emissions-related OBD2 data.
✕Not intended for the separate 2-pin plug next to the connector; use that only for flash codes.
✕Not required for Honda models that already have a 16-pin connector; connect those directly.

Applications and functions

This cable is intended for garages and mechanics who read out older Honda models with the 3-pin connector.

Control units you can access

  • Engine management: PGM-FI engine management.
  • Other systems: Varies by model and equipment.

What you can do

  • Fault codes: Read and clear.
  • Live data: Where the diagnostic tool provides it.
  • Fault finding: Check sensors and signals.

How to use it

  1. Finding the connector: Look on the passenger side under the dashboard.
  2. Connecting: Insert the 3-pin plug into the blue connector.
  3. Connecting the scan tool: Connect the 16-pin plug to the cable.
  4. Ignition on: Switch the ignition on without starting the engine.
  5. Reading out: Select Honda, the model and the control unit.

Compatible vehicles and applications

The deciding factor is the 3-pin diagnostic connector, often with a separate 2-pin plug beside it. The cable is suitable for, among others, the following Honda models with that connector:

Honda:

  • Civic (EJ/EK/MA/MB): 1996 to 2000.
  • CR-V (RD1): 1996 to 2001.
💡
Good to know: On most models the connector is located on the passenger side, under the dashboard compartment or near the centre console. On the CR-V (RD1) it is sometimes higher in the dashboard, behind the radio surround. You can recognise it by the small blue plug.
