The Jaltest JDC408A is the adapter cable that converts the 16- and 32-pin connectors from the gateway module in Renault and Nissan commercial vehicles to the standard 16-pin OBD2 interface. Rather than connecting to the vehicle's diagnostic port, you attach it directly to the gateway connector in the wiring harness, ensuring diagnostics bypass that module. On the other end, you connect your Jaltest diagnostic cable.
Behind that gateway lies the commercial vehicle network. Once connected, the diagnostic equipment can access the engine control unit EDC MD1, the brake and stability control system ABS/ESP V7.0, the body control module BCM and the exhaust aftertreatment system SCR Gen4. This cable is part of the Jaltest CV (commercial vehicles) range.
