Honda 3-pins OBD1 to 16-pins OBD2 Adapter Cable – Passenger Car
The Honda 3-pin to 16-pin OBD2 adapter cable is a specialized diagnostic adapter designed to connect modern reading equipment with older Honda passenger cars. Many Honda models produced before 1996 use a specific 3-pin or 5-pin diagnostic connector instead of the standardized 16-pin OBD2 port. This connection is usually located on the passenger side under the dashboard.
This adapter cable functions as an indispensable bridge connecting the pins of the 3-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 enables a more efficient fault diagnosis than the traditional "paperclip method".
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 the illuminated check engine light. Depending on the scan tool, it may also be possible to clear the fault codes after repair.
Compatible with the following vehicle makes and models:
This adapter cable is compatible with a wide range of older Honda models equipped with the 3-pin diagnostic connector. Examples of compatible models include:
- Honda Civic (pre-1996)
- Honda Accord (pre-1996)
- Honda CRX / Del Sol
- Honda Prelude (pre-1996)
- Honda Integra
It is strongly recommended to always check the physical connection in the vehicle before purchase.
