The Jaltest JDC108A is the adapter cable for the Haldex EB+/TRS braking system and the Haldex TPMS tire pressure monitoring with the manufacturer-specific 4-pin connector; on the system side sits that connector, on the interface side the 16-pin OBD2 of your Jaltest diagnostic cable. The connection belongs to the Haldex control unit on the trailer chassis, so both systems connect through the same plug.
With this connection, the Jaltest equipment reads out both systems. With EB+/TRS, the coverage goes beyond reading: In addition to fault codes and measured values, you can control components and adjust parameters. With Haldex TPMS, it's limited to reading fault codes. Since trailers have never been required to have a standardized diagnostic connector, this plug remains in use on newer trailers as well. The cable falls under Jaltest CV (commercial vehicles).
