 Module Q&A

7.1.1  Q:  The  SmarTire  Trailer-Link

™

  module  does  not  connect  to  the 

tractor.    How  can  the  SmarTire  Trailer-Link  module  be  diagnosed 

further? 

A:  In the event that the SmarTire Trailer-Link ECU does not connect with the 
SmarTire vehicle-mounted TPMS system, follow these steps:

1. 

Check to make sure the SmarTire Trailer-Link ECU and vehicle-mounted 

TPMS ECU power up during start up.  The red diagnostics LED (P/N 

K075866) on the SmarTire Trailer-Link harness should light up during 

power-up to confirm that power is being supplied to the SmarTire Trailer-

Link ECU.

2. 

Ensure the SmarTire Trailer-Link Enable function is set in the SmarTire 
tow-vehicle-mounted ECU part number 200.0216 and that the tow-vehicle 

ECU is loaded with TPMS firmware part number is 248.0091 min. version 

1.02 and CAN firmware part number 248.0092 min. version 1.03.  Use 

Bendix ACom 6.6 (or later) Diagnostics to verify the software version on 
the vehicle-mounted ECU.

3. 

Check the SmarTire Trailer-Link harness to ensure all connections are 
secure.  Ensure the locking tab on the ABS-power splice is engaged as 
well as the main connector on the SmarTire Trailer-Link ECU module.

4. 

Cycle power to restart the link-up process and reset the ECUs.

5. 

If the SmarTire Trailer-Link ECU still does not connect with the SmarTire 
vehicle-mounted TPMS system please refer to 7.1.4 for further 
Diagnostics.
