This is the Bosch Power Line Carrier (PLC) adapter for the Bosch ESI Truck tool.


  • J2497 Power Line Carrier (PLC) communication compatible.
  • Allows direct connection to trailer.
  • Works with tractor present or without the tractor present (external power supply is necessary without tractor).
  • Bosch ESI[Truck] trailer ABS coverage for Bendix, Haldex, Meritor Wabco, and Wabash systems

You can't always connect to a trailer ABS through the truck, so you would need this adapter to connect directly to the trailer. You would either use this adapter "in-line" with your 7-way plug from the truck or else purchase the extra cable kit to connect to a battery.
