The Jaltest JDC122A adapter cable connects a standard 16-pin OBD2 connector to a specific 12-pin Bendix connector. This adapter cable is designed for direct communication with specific trailer diagnostic systems. It enables diagnostic technicians to hardware-connect to the tire pressure monitoring system of towed vehicles.
Within the diagnostic context, the interface acts as a bridge between the Jaltest Link interface and the Bendix control module. This allows current measured values from wheel sensors to be read and specific network parameters to be configured. The integrated electronics module in the wiring ensures correct pin mapping and signal conversion for the required communication protocol.
