The Jaltest JDC602A is the diagnostic cable for BRP Sea-Doo jet skis; it connects the 6-pin diagnostic connector to the 16-pin OBD2 port of your Jaltest diagnostic device. The 6-pin connector is located in the engine compartment of the jet ski.
With this connection, the Jaltest equipment reads four control units on board: the brake and reverse system iBR, the multiplex module MPEM, the engine control ECM, and the instrument cluster INS. The coverage difference is significant: The iBR and MPEM provide fault codes, live data, component control and parameters — and the iBR also includes calibration — while Jaltest reads only live data and wiring diagrams from the ECM and INS, with no fault codes. The cable falls under Jaltest Marine.
