5.2 Tractor SmarTire
®
TPMS Dash Display Alerts
After the SmarTire Trailer-Link
™
connection has been established, the same
three tire alerts, first level pressure, second level pressure and temperature
alerts will be reported from the trailer that are reported from the tractor-
mounted SmarTire
®
TPMS system. In addition, trailer tire sensor Diagnostic
Trouble Codes (DTCs) and low battery alerts will also be reported. Please
note, alert levels configured in the tractor TPMS ECU do not override the
settings in the SmarTire Trailer-Link ECU. For example, if the tractor has its
first level alert set to 10% -- but the SmarTire Trailer-Link ECU is configured
for a 15% first level alert – the driver will see trailer tire alerts based on the
15% figure stored in the Trailer-link ECU.

To SmarTire TPMS
Dash Display Link-Up Procedure
The SmarTire
®
ECU must be configured to allow SmarTire Trailer-Link
connections. There are three options available and can be configured with
the Bendix ACom 6.6 (or later) diagnostic software.
1.
Disabled: In this mode Trailer Linking is disabled and trailer tires will not
show up on the dash display.
2.
Automatic Learn Mode: In this mode the SmarTire ECU will try and auto
detect the attached trailer. In this mode the SmarTire Trailer-Link should
link up within 30 seconds but could take as long as 5 minutes.
3.
Dedicated Trailer Mode. In this mode the ID code of a particular trailer
can be programmed into the SmarTire ECU. This mode is normally used
if the tow vehicle always pulls the same trailer. Link-up in this mode
should take 30 seconds.
When the tractor drops a trailer, it will unlink from the SmarTire ECU in 9
minutes at which time the dash display will remove the trailer tires.
5.4 Trailer Lamp Blink Codes
If an optional trailer lamp is installed and connected via the lamp output on
the SmarTire Trailer-Link ECU, the following table shows the blink codes that
will be displayed by the system in the event of an active Diagnostic Trouble
Code (DTC) condition. The SmarTire Trailer-Link lamp alerts will be displayed
for one (1) minute after system power-up and then will either show the lamp
on — or off — depending on status of the system.
