The Honda 5-pin to 16-pin OBD2 adapter cable is a specific diagnostic adapter designed to connect modern reading equipment with older Honda passenger cars. Many Honda models produced before the general introduction of the OBD2 standard use a 3-pin or 5-pin diagnostic connector. The 5-pin connector is usually located on the passenger side, hidden under the dashboard.

This adapter functions as an indispensable bridge connecting the pins of the 5-pin port to the corresponding inputs on a 16-pin OBD2 scanner. This allows both the professional mechanic and the do-it-yourselfer to read the onboard computer of these classic Honda vehicles with a suitable, protocol-compatible scanner. This significantly simplifies fault diagnosis compared to older, manual methods.


Application and functionality:

The primary application of this adapter cable is to enable electronic diagnostics on older Honda vehicles. By using this adapter in combination with a scanner that supports Honda-specific OBD1 protocols, the user can access the engine management system.

The functionality includes reading diagnostic trouble codes (DTCs) to determine the cause of a lit engine warning light. Depending on the scan tool used, it may also be possible to clear fault codes after repair.


Compatible with the following vehicle makes and models:

This adapter cable is compatible with a range of older Honda models equipped with the 5-pin diagnostic connector. Examples of compatible models include:

  • Honda Accord: approximately 1992–1995
  • Honda Civic: approximately 1992–1995
  • Honda Prelude: approximately 1992–1995
  • Acura Integra: approximately 1994–1995
  • Acura Legend: approximately 1991–1995

It is strongly recommended to always check the physical connection in the vehicle before purchase to be sure whether the vehicle has a 3-pin or 5-pin connector.
