The PLC TestCon serves as a PLC4TRUCKS to J1708 converter so that J1708 protocol adapters can be used to communicate with Trailer ABS diagnostic applications such as those from Meritor-WABCO, Bendix, Haldex, and Wabash National. It also quickly tests both the Trailer ABS and the Trailer ABS Fault Lamp without the need for a PC.

Trailer ABS Diagnostics Adapter
The PLC TestCon is a low-cost solution for running Trailer ABS diagnostics without having to purchase an additional RP1210-compliant adapter that has PLC4TRUCKS support.
Since most fleet service bays have RP1210-compliant adapters that support the J1708 protocol around the shop, you can simply plug in the PLC TestCon to that adapter and connect your existing cabling to the PLC TestCon. Select the “J1708” protocol in your Trailer ABS diagnostics application and you are ready to run Trailer ABS diagnostics!

Quick Trailer ABS Fault Check (Go/No Go) Without a PC<
In the default mode of operation called “Tractor Mode”, the PLC TestCon simulates a tractor. It listens to the PLC data bus and if a Trailer ABS fault exists, the “Trailer ABS Fault” LED will illuminate.
In this mode, it also “gateways” messages from the PLC to the J1708 data bus and vice versa so that an RP1210 protocol adapter can be used to run PLC-based Trailer ABS diagnostics. This means you do not need to purchase a full-priced PLC/J1708 Adapter.

Quick Tractor “In-Cab Trailer ABS Fault Lamp” Check Without a PC
In “Trailer Mode”, the PLC TestCon sends “Trailer ABS fault messages” on the PLC databus causing the tractor’s “Trailer ABS Fault Lamp” to toggle off and on.
This feature is an excellent choice for tractor, trailer, and Trailer ABS OEMs to use in their end-of-line (EOL) testing without having to use a more expensive PLC solution, custom wiring, and a PC.
