BENDIX BW2920 manual Trailer Sensor ID Walk-Around Learn Procedure

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.
