The Jaltest JDC402A is an Adapter Cable specifically developed for connecting diagnostic equipment to older Volkswagen Delivery vans. This cable bridges communication between the older 2+2-pin OBD1 diagnostic connection of the vehicle and the standardized 16-pin OBD2 connection of modern reading devices. This makes it possible to read and diagnose vehicles that are not equipped with a standard OBD2 port.
The cable not only facilitates data transmission via the K-Line, but also supplies the connected diagnostic device with power from the vehicle's electrical system. The construction is designed for use in a workshop environment and ensures a stable connection during diagnostic tasks. The JDC402A is a component within the Jaltest diagnostic platform, focused on commercial vehicles.
Application and functionality:
This Adapter Cable makes it possible to connect diagnostic systems with a 16-pin OBD2 connector to older Volkswagen vehicles with a 2+2-pin connection.
- Diagnostic connection: Forms a physical and electronic bridge between the vehicle and the diagnostic device, enabling communication with the control units.
- Compatibility: Makes modern diagnostic equipment compatible with older diagnostic protocols that run through the 2+2-pin connector.
- Power supply: Provides the necessary power to the connected reading device, directly from the vehicle's diagnostic port.
Compatible vehicles and Application:
This cable is primarily intended for older Volkswagen delivery vans and light commercial vehicles equipped with the double 2-pin diagnostic connection.
Volkswagen:
- Caddy (9K): (1995-2004)
