Sensor Straps. Sensors are mounted to the surface of the rim using a stainless steel strap, a reliable and universal method of sensor installation. Harness. Designed to not require a separate power supply, the harness supplies trailer ABS system power to the SmarTire Trailer-Link Tire Pressure Monitoring System ECU. 1.2 Maintenance Tool Maintaining tires in the yard is just as important as real-time tire information for the driver, but many TPMS systems don’t include functionality to help...
Page 8 Industrially-designed for the rugged requirements of a commercial trailer chassis, the SmarTire Trailer-Link ECU can monitor up to eight (8) wheel positions when linked with a tractor with SmarTire TPMS, and more when applied as a stand alone trailer TPMS. The total number of tires monitored on both the tractor and trailer cannot exceed twenty.
Page 9 1.4 Fundamentally, Why Is Temperature Monitoring Important? The Pressure/Temperature Relationship Tire manufacturers specify that tire pressures should be checked and adjusted when a tire is “cold”, but most people may not know why, or even what a “cold tire” is. The temperature of a tire actually has a significant impact on its inflation pressure.
Page 10 The charts below illustrate the equivalent inflation values for a series of Cold Inflation Pressures (CIPs) at various temperatures. The temperature values represent the temperature of the air contained inside the tire. This temperature can be estimated for a cold tire using the outside, ambient temperature. Chart 1 Chart 2 The charts above are to be used as a guide only.
Page 11 “Temperature Compensated” pressure deviation values and alerts. By measuring the operating temperature of a tire and comparing it to the CIP value programmed into the system, the SmarTire Trailer-Link system will know what a tire’s pressure is supposed to be in relation to its operating temperature.
Page 12: Tire Maintenance
The advantages of temperature compensation are even more dramatic when a tire has a slow leak. A tire that is constantly losing pressure will not be able to reach thermal equilibrium because the contained air simply cannot expand enough to generate the required pressure, regardless of how hot the tire becomes.
Page 13 IMPORTANT READ THESE INSTRUCTIONS PRIOR TO INSTALLATION ™ This SmartTire Trailer-Link TPMS kit is pre-programmed and ready to use, subject to your application: ● The sensors have been PRE-ASSIGNED TO WHEEL POSITIONS and are identified on each unit with a position label (P1, P2, P3, etc.) – install the sensors as shown in Figure 1.
Page 14: Section B - System Installation - Tire Sensors
Section B - System Installation – Tire Sensors 3.0 System Installation: Tire Sensors 3.1 Sensor Overview ® The SmarTire TPMS sensor monitors tire pressure and temperature every twelve (12) seconds and transmits tire data every three (3) to five (5) minutes. If a pressure change of 3 PSI is detected, the sensor will not wait for the next regular transmission and will transmit tire data immediately.
Page 15 Tire changing equipment Tire balancing equipment 3.3 Tire Sensor Installation Remove the wheel from the vehicle and then remove the tire. Wrap the strap around the rim in the lowest point of the drop center well and mark it 1” (2.5 cm) past the worm gear. Cut the strap at the mark. Excess strap MUST be removed or it will break-off and damage the tire.
Page 16 3.4 Re-mounting Tires After A Sensor Has Been Installed Please read this section carefully and follow each step precisely to ensure you do not damage the sensor when mounting the tire. If steps are not taken to avoid the sensor located in the drop center well of the rim, it can be damaged by tire beads as the tire is mounted.
Page 17 3.4.2 Re-Mounting Tires Using Tire Irons To avoid damaging the sensor, simply mount the tire ensuring that the last part of the bead to slip over the flange happens directly at the sensor. Start at one end of the tire and work towards the opposite end with the tire oriented so that the beads are first pushed under the rim flange directly opposite the sensor (1) and then worked over the flange toward the sensor (2).
Page 18 3.4.3 Re-Mounting Commercial Tires Using a Vertical Tire Machine Place the rim on the machine so that the rim flange clamp is at the 12 o’clock position, the sensor is at the 2 o’clock position and the mounting hook is at the 8 o’clock position. Rim Flange Clamp Sensor Figure 8...
Page 19 Place the tire on the rim with the bottom bead under the flange at the 6 o’clock position with the mounting shoe at the 9 o’clock position. Advance the mounting shoe clockwise to pass the lower bead over the rim flange. Return the mounting shoe to the 9 o’clock position, depress the upper bead under the rim flange at the 6 o’clock position and advance the mounting shoe clockwise until the second bead is completely mounted.
Page 20 Advance the turn-table clockwise using the mount head to guide the rest of the bottom bead over the flange and on to the rim. When assembled correctly, the bead will slip over the flange without contacting the sensor. Repeat for the top bead. Do not allow the pinch point to slip as the rim rotates or the sensor could be broken.
Page 21 3.5.2 Using a Tire Mounting Machine After removing the deflated tire / wheel assembly from the vehicle, unseat the beads directly opposite the sensor and valve stem. The sensor should be located at the valve stem (the rim mounted decal should also indicate the sensor’s location).

Page 30 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.
Page 31 TPMS Maintenance Hand Tool, go to the first tire to ® Using the SmarTire be programmed and proceed to activate each of the trailer’s tire pressure sensors in the proper order. Starting on the left side (road side) of the trailer at the forward axle, begin by activating the inner tire and proceed to work counterclockwise from inner to outer tire.

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: Check to make sure the SmarTire Trailer-Link ECU and vehicle-mounted TPMS ECU power up during start up.
Page 42 A: After the wireless link between the tractor SmarTire TPMS ECU and ™ the SmarTire Trailer-Link module has been established and the gauge has rebooted, trailer tire sensor data will be displayed within five (5) to eight (8) minutes on the gauge.
Page 43 7.1.3 Q: When the Gauge first powers up, the alert lamp is blinking and a triangle with an exclamation mark is displayed. A few minutes later the alert clears and the display returns to normal. Was there an alert? A: During the start up sequence, the Gauge may clear itself of a previous alert condition or issue a momentary alert if a tire sensor has not reported in.
Page 44 7.1.4 Q: What additional diagnostic information is available? A: The external LED part # K075866 is connected via the cable harness as a separate plug. Please refer to Section C, 4.0, step 7 for details on installation and location of this LED. The LED functions as described in the table below. Flashing with pattern will have periods of 0.3 second on and 0.3 second off repeating every 6 seconds.
Page 45 Notes for Table 5 Note 1: This Diagnostic Trouble Code (DTC) occurs when the SmarTire ™ Trailer-Link ECU has not received information from a tire sensor for 35 minutes. Possible causes are: A tire has been replaced and a tire sensor is no longer in range of the ECU and is therefore no longer being received.
Page 46 A: Wheel assemblies may have been relocated/rotated on the trailer without ™ the SmarTire Trailer-Link ECU having been updated. To correct this, follow ® the steps in Section C, 4.2.3 in combination with the SmarTire TPMS Maintenance Hand tool to relearn sensors into their correct tire positions.
Page 47 it may simply be pressed into a new cradle for reuse. Avoid reusing the strap – worm gear could be damaged internally. If points a. and b. did not yield any results, the sensor is either missing or has been damaged. Remove the wheel carefully and inspect the inside tire lining for any damage if the sensor, strap, and cradle are found to have been damaged and non-operational.
