New diagnostic tool fast-tracks ABS data

There’s so much focus on what an engine can tell you about the performance of the truck, it’s easy to forget about the tails a trailer can tell.

Meritor WABCO now offers a new diagnostic tool — called PLC DataMaster — to tap into your trailer’s anti-lock braking system. Compatible with Meritor WABCO’s Enhanced Easy-Stop ABS, the device uses power line carrier (PLC) communications and a sophisticated memory structure to extract readings from up to 500 trailers. The result: it requires less time for data retrieval than traditional methods and creates less paperwork in the process.
 
The self-contained, hand-held device quickly connects to a parked trailer’s J560 seven-way connector, eliminating the need for cumbersome laptop PC/interface connections.
 
With a few simple keypad commands, the 20-character display shows vital trailer statistics related to ABS status codes, trailer identification, and odometer readings.
