The Jaltest JDC525A is the adapter cable connecting the 14-pin diagnostic connector on tractors from Claas and Renault to the 16-pin OBD2 port of your Jaltest diagnostic cable. On the vehicle side, the 14-pin connector plugs into the diagnostic port in the cab; on the interface side, the 16-pin OBD2 inlet connects to your diagnostic tool. The same Renault/Claas tractor family also comes with a 4+4-pin diagnostic connector; this is the 14-pin version.
The cable opens the diagnostic line to the tractor's control modules. On the most powerful models, the ATLES 9X5-9X6, you'll find the Deutz engine controllers EMR and EMR2 - EDC, the RCC/RCC2 vehicle control unit, the TC transmission, the ELECTROPILOT valve control, and the TCE lifting systems; on the ARES 7X5, coverage is limited to the QUADRISHIFT/TWINSHIFT gearbox and DBD2 instrument cluster. Since agricultural vehicles aren't subject to OBD requirements, this connector remains in use alongside the 4+4-pin version. The cable falls under Jaltest AGV (agricultural vehicles).
