The new Universal J560 PLC Adapter now interfaces with all WABCO PLC trailer brakes. In addition, we've improved communication performance, making the J560 PLC Adapter essential for anyone working with ABS brakes. This product extends the capability of J1708/J1587 diagnostic tools to support J2497 Power Line Carrier (PLC) communication. Basically, it extracts data from the power line and converts it to J1708. You can use the Universal J560 PLC Adapter with a generic ABS diagnostic software application to do the following: Detect ABS warning lamp messages coming from the trailer ECU. Test the in-cab trailer ABS warning lamp. Test SAE J1708 MID 10 and 11 messages. Test SAE J1587 MIDs 136 through 139. In addition, you can connect the Universal J560 PLC Adapter to a vehicle between the tractor and the trailer, or to the trailer alone without the tractor. The Universal J560 PLC Adapter can be used with virtually any heavy-duty vehicle communication interface or scan tool.
