7.1SmarTire® TPMS Gauge Display And SmarTire Trailer-Link™Module Q&A
7.1.1Q: 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.
