4.1 Configuring & Customizing Your
SmarTire Trailer-Link ™ System
During the installation process, the default settings for SmarTire Trailer-Link ™
TPMS should be customized to the trailer by the installer. Using the SmarTire
Trailer-Link Diagnostics Software within Bendix ® ACom ® Diagnostics 6.6 (or
higher), alert thresholds can be made more or less sensitive and system
settings can be adjusted to accommodate trailer changes and use.
Replacing trailer tires or installing the system on a new trailer may also require
adjustment of pre-configured settings. The following section describes how
to adjust the pre-configured settings of your SmarTire Trailer-Link TPMS.
4.1.1 Pre-Configured Settings
Generally, the SmarTire Trailer-Link TPMS is pre-configured with the default
settings listed below. Depending on your vehicle, your system may have a
different initial setup.
● Cold Inflation Pressure (CIP):
◊ 4-Wheel (2-axle Configuration)
• Trailer Axle 1&2: 100 PSI (6.89 bar)
◊ 8-Wheel (2-axle Configuration)
• Trailer Axle 1&2: 100 PSI (6.89 bar)
● First Alert Level (FAL) Pressure Deviation Alert: CIP ±15% (temperature
compensated)
● Second Alert Level (SAL) Critical Low Pressure Alert: CIP -20%
● High Temperature Alert: 185°F (85°C)
Default cold inflation pressure settings should always be customized to the
trailer. Check the trailer’s placard or the industry published load inflation
table to determine the recommended cold inflation pressure settings. Bendix
recommends setting the Second Alert Level (SAL) critical low pressure alert
at 20% below the recommended cold inflation pressure for your trailer. Bendix
also does not recommend changing the First Alert Level (FAL) pressure
deviation alert setting as well as the High Temperature Alert setting of 185F.
To make changes to the FAL, SAL, and High Temperature settings refer
to the SmarTire Trailer-Link Diagnostics settings within Bendix ACom
Diagnostics. For programming sensor IDs and changing the axle CIP using
the Maintenance Hand tool, see the instructions that follow. These instructions
can also be found in the Maintenance Hand tool manual (BW2809).
