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.

5.3SmarTire Trailer-Link™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.
