The Jaltest JDC538A is the diagnostic cable that connects the 6-pin connector of Yanmar industrial engines to the Jaltest Link. On the engine side, you'll find the 6-pin connector; on the interface side, the 16-pin OBD2 connection of your Jaltest diagnostic cable. The connector is engine-specific and located on or near the engine block, not in a fixed position on the machine.
The cable opens the diagnostic line to the engine control units EDC Yanmar Bosch and EMS Yanmar Denso, including their Stage V versions, as well as to the DCU of the exhaust aftertreatment system. With EDC Bosch and EMS Denso, coverage includes not only reading data but also maintenance intervals and additional actions; the Stage V version does not include additional actions. The cable falls under Jaltest OHW (Off-Highway machines) and Jaltest Marine.

Yanmar engines are installed as standalone power units in compact machinery, equipment sets and implements; Jaltest provides diagnostic coverage for these engine series. You'll need to check on-site which connector is fitted to your engine block.
