4.2.3 Trailer Sensor ID Walk-Around Learn Procedure
The following steps are only to be used for the SmarTire Trailer-Link
™ ECU.
When the tires are rotated or replaced on a trailer equipped with a SmarTire
tire pressure monitoring system, the trailer TPMS module must be taught the
new position of each sensor ID code. The Walk-Around Learn procedure is
used to activate each sensor in its new location, store the sensor information
and download this information into the SmarTire Trailer-Link ECU.
The SmarTire Maintenance Hand Tool (P/N 090.0011) will learn and store the
location of each sensor as the user walks around the trailer in a U-Shaped
pattern, starting at the left side (looking forward) front most tire location (see
Figure 28). If this is a dual tire axle, start with the inner tire location. The new
location information (ID codes) for each sensor collected is then uploaded to
the SmarTire Trailer-Link receiver.
1. Power up the SmarTire Trailer-Link receiver. In most cases the trailer
will need to be connected to a tractor in order to receive power. The
diagnostic LED on the SmarTire Trailer-Link harness can be viewed at
power up to ensure that the ECU has power.
2. Using the Maintenance Hand Tool, press and hold the Setup button
until a list of menu items appear.
3. Select the Walk-Around Learn icon and press the Return button.
4. Use the Up and Down arrow buttons to select the number of tires
on the trailer.

5. When the correct number of tires is selected, press the Return button
to initiate the walk around learn procedure.
