(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
™

Flex
™
program for your vehicle(s).
