J1708/J1587 DIAGNOSTIC LINK
The Premium TABS-6 module provides a J1708/J1587
diagnostic link with data and power to communicate with
the vehicle and various diagnostic tools. Diagnostics,
testing, confi guration, data transfer and other functions
can be performed using this link. Diagnostic tools such as
the MPSI Pro-Link
™ device and Bendix ® ACom ® Diagnostic
Software (version 4.0 and higher) support the TABS-6
Module.
Ignition power must be provided to the TABS-6 module for
the diagnostic link to be active.

The Standard module provides for one auxiliary I/O
function.
The Premium module provides for up to fi ve auxiliary
functions and one additional ground. See Chart 3, below.
Bendix ® ACom ® Diagnostic Software (version 4.0 and
higher) supports the confi guration of the TABS-6 module
auxiliary I/O’s.
ABS FLEX ™ PROGRAM
The ABS Flex ™ program uses Auxiliary Design Language
(ADL) to allow customized auxiliary functions to be carried
out by the TABS-6 module. Programs developed in the ABS
Flex
™ program may be downloaded at the production line
or in the fi eld to control non-braking functions of the trailer.
For example, ABS Flex ™ program can potentially
communicate the status of: tire infl ation and/or temperature;
reefer temperature; load presence; slider pin position; lift
axle position; proximity/reverse alarm; and vehicle weight.
ABS Flex ™ programs monitor the auxiliary I/Os and/or the
SAE J1587 diagnostics and SAE J2497 PLC data links.
Contact your Bendix Account Manager to discuss an ABS
Flex
™ program for your vehicle(s).
