The Universal J560 PLC Adapter, No. 604020, from NEXIQ Technologies now interfaces with all WABCO PLC trailer brakes. In addition, it’s field-updatable. Users can connect the J560 PLC Adapter to a vehicle between the tractor and the trailer, or to the trailer alone without the tractor. The product extends the capability of J1708/J1587 diagnostic tools to support J2497 Power Line Carrier (PLC) communication. It extracts data from the power line and converts it to J1708. It can be used with a generic ABS diagnostic software application to detect ABS warning light messages coming from the trailer ECU, test in-cab trailer ABS warning lamps, and test SAE J1708 MID 10 and 11 messages and J1787 MIDs 136 through 139.
