FCC Compliance Label The FCC compliance label is located on the back of the Tool as shown in Figure 1. Figure 1 This device complies with part 15 of the U.S. Federal Communications Commission (FCC) Rules and with RSS-210 of Industry Canada. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Introduction The tire pressure monitoring system consists of a tire pressure sensor inside the tire that transmits a radio frequency (RF) signal containing a unique identification number (ID #), actual tire pressure, and sensor battery condition to a module in the vehicle. The vehicle module receives and interprets the RF signal from the sensor and warns the driver of low tire pressure.
Main Menu Figure 3 Initiate Function If the Initiate button is pressed, the Tool retrieves the sensor ID, pressure data and battery status from the sensor which is displayed. Review the Application section of this guide (page 21) for more information. Setup Menu If the Setup button is pressed, the Tool enters the Setup mode. Review the Application section of this guide (page 21) for more information. Learn Function If the Learn button is pressed, the Tool learns/displays the sensor ID.

ICON psi/BAR/kPa/C/F STATE DESCRIPTION Software Update This icon indicates the software update option which allows the user to download the latest software from a personal computer. Measurement Units This option allows the user to change the units of the parameters displayed. See page 10.
Set-up Menu Icon Explanations Software Update The software update function is used to download the latest SmarTire® by Bendix CVS Maintenance Tool software from a personal computer. The current and legacy versions of the SmarTire software are available on the Manuals page of the www.SmarTire.com site and also on www.bendix.com. Refer to update information supplied with future software updates.
Maintenance Tool Software Update Program Figure 5 Updating The Maintenance Tool Figure 6 psi/BAR/kPa/C/F - Measurement Units This function changes the measurement units of the parameters displayed: psi (pounds [pound-force] per square inch), BAR (equal to 100 kilopascals), kPa (kilopascals), C (Celcius), and F (Fahrenheit). Stored Sensor Information Retrieval This function allows the user to refer to sensor information stored in the Tool memory. Up to 100 sensor readings can be stored & retrieved.
Delete Sensors in Memory This function is used to delete all sensor data stored in the Tool memory. Walk-Around Learn Walk-Around Learn Procedure When the tires are rotated or replaced on a vehicle with a tire pressure monitoring system, the vehicle must re-learn the position of each tire. The Walk-Around Learn procedure is used to activate each sensor in its new location, store the sensor information, and download to the vehicle’s tire pressure sensor receiver.
8. After the last tire has been learned, press the down arrow. The Tool is now ready to transmit this information to the vehicle’s tire pressure sensor receiver. 9. Using the supplied cable, connect the Tool to the diagnostic port of the tire pressure sensor receiver. See Figure 8. Figure 8 10. Press the check mark to begin downloading the new tire sensor IDs into the receiver. 11. If there is a communication error, the Tool displays an alert. Check all the connections and try again. 12.
. Make sure the number of tires entered on the Tool matches the number of tires being monitored on the vehicle and then repeat the Walk-Around Learn procedure. Ambient Pressure Sensor Learn Ambient Pressure Sensor Learn is used to activate and store atmospheric pressure information from the ambient sensor to compensate the displayed readings for changes in altitude. Ambient Pressure Compensation 1. Scroll down the Menu and set the Maintenance Tool to Ambient Sensor Learn. 2.
TRAILER COLD INFLATION PRESSURES (CIP) Program CIP of Axles in TrailerLink™ System by Bendix CVS ECU CIP Programming Procedure TPMS pressure warning levels are calculated as a percentage of a tire’s cold inflation pressure (CIP). The default levels are 15% below the CIP (temperature compensated) for the first alert level, and 20% below the CIP (non-temperature compensated) for the second warning level. The default CIP programmed into the TrailerLink™ system ECU is 100psi for all axles.
6. When the CIP values have been adjusted to the desired setting, press and hold the Return button for 3 seconds until the programming screen bellow is displayed. 7. Using the TrailerLink™ system programming cable (Part Number K092501), connect the Tool to the TrailerLink system harness. Refer to the TrailerLink system manual (BW2920) for instructions. ECU HAND TOOL REMOVE LED INSERT HARNESS 8. Press the Check button to initiate programming.
12. In the case of a programming error, the failure screen (shown below). If this occurs, ensure the TrailerLink™ system by Bendix ECU is powered and the connection from the Tool to the TrailerLink system harness is correct. Press the Check button to retry the operation; press the Return button to return to the CIP adjustment screen in step 5; or press the button to abort the programming and return to the main menu.
6. Using the Maintenance Hand Tool, go to the first tire to 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 the outer tire. Work in a U-shaped pattern around the trailer ending with the right side (curb side) forward outer tire.
9. If a sensor failed to activate, this screen will be appear: If this occurs, ensure that the Tool is placed at the correct position around the tire and retry the sensor activation by pressing the Learn button. 10. If, while learning a particular wheel position, a tire pressure sensor ID code is received that is already used in a different position, this "Duplicate ID" error screen is displayed: 11. Pressing the button will delete the received ID and the screen will go to the previously learned position.
14. In the case of a programming error, the following screen is shown. 15. If this occurs, ensure the TrailerLink system ECU is powered and the connection from the Tool to the TrailerLink system harness is correct. Press the Check button to retry the operation; press the Return button to return to the learn procedure screen in step 5; or press the button to abort the learn procedure and return to the main menu. 16.
Battery Initiate Set Up Figure 10 Sensor Learn Screen Execution Icons ICON STATE DESCRIPTION Confirm Good X Cancel Cancels current action. Back Back, Select, Enter, Return to main menu. Scroll Scroll displayed data or selection. Sensor information was not received. Alert If in Walk-Around Learn mode, the sensor ID has already been designated to a tire location. Sensor Maintenance The battery of the tire pressure sensor may be low.
Troubleshooting Examples Figures 11 through 14 show examples of potential screens after activating a sensor (within LF sensor range) using the Initiate command. The received information by the Maintenance Tool is stored in the Tool memory and can be recalled by selecting the Sensor Information Storage command in the menu settings.

Troubleshooting Problem Potential Solution The Tool does not power up or turns off when the Initiate button is pressed. Replace batteries. No tire pressure sensor data is received. Make sure the antenna is held within 22 inches of the tire pressure sensor in position before the Initiate button is momentarily selected. The Tool should be held in that position for at least 3.5 to 5 seconds. If still unsuccessful, try to activate and receive tire pressure sensor data from another tire pressure sensor.
