Toyota 22-pins OBD1 to 16-pins OBD2 adapter cable – Passenger car
The Toyota 22-pin to 16-pin OBD2 adapter cable is a specific diagnostic adapter designed to bridge older Toyota passenger cars and modern OBD2 diagnostic equipment. Many Toyota models from before the general introduction of the OBD2 standard (around 1996) are equipped with a unique, rectangular 22-pin diagnostic port. This connection is usually located in the engine compartment and is physically incompatible with the 16-pin plugs of contemporary scanners.
This adapter is an essential tool for both the professional automotive technician and the do-it-yourselfer who wants to maintain classic or older Toyota vehicles. Using this cable makes it possible to access the vehicle's onboard computer with a suitable, protocol-compatible scan tool. The design focuses on durability and reliable signal transmission, minimizing diagnostic errors caused by poor connections.
Application and functionality:
The primary function of this adapter cable is to establish a stable physical connection between the 22-pin DLC (Data Link Connector) of a Toyota and a standard 16-pin OBD2 diagnostic device. This allows the user, depending on the capabilities of the scan tool:
- Read and clear diagnostic trouble codes (DTCs)
- View live sensor data
- Perform other basic diagnostic functions
This allows the user to efficiently analyze engine management issues and other systems without relying on the outdated "paperclip method" for reading blink codes.
Compatible with the following vehicle makes and models:
This adapter is compatible with a wide range of Toyota passenger cars produced from around the late '80s to the mid '90s. The presence of the 22-pin port is decisive here. Models where this connection is often found include:
- Toyota Camry (pre-1996)
- Toyota Celica (incl. T180, T200)
- Toyota Corolla (e.g. E90, E100)
- Toyota MR2 (e.g. SW20)
- Toyota Land Cruiser (e.g. 80 Series)
- Toyota Supra (e.g. A70, A80 pre-OBD2)
- Toyota Starlet (e.g. P80)
Also compatible with some older Lexus models.
