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, configuration, 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.

AUXILIARY I/O

The Standard module provides for one auxiliary I/O function.

The Premium module provides for up to five auxiliary functions and one additional ground. See Chart 3, below.

Bendix® ACOM™ Diagnostic Software (version 4.0 and higher) supports the configuration 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 field to control non-braking functions of the trailer.

For example, ABS Flex™ program can potentially communicate the status of: tire inflation 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).

The TABS-6 module has a Customer Scratch Pad feature which allows the customer, or end-user, to store up to 756 bytes of information. This information can then be read using the Bendix® ACOM™ Diagnostic Software (version 4.0 and higher).

If additional scratch pad space is needed, this storage space can be expanded to 1K (1,008 bytes total of data). Contact Bendix for further details.
