Tire Monitoring System SEA Activation

If the tire monitoring system was "Installed" as part of the check-in step of "Chassis ECM Update", when the machine is powered back ON, the chassis ECM will automatically attempt to detect whether it is communicating with a Cat tire monitoring receiver or a third-party interface ECM. Proceed to Step j in the following procedure to determine if the chassis was able to detect the receiver:

Note: Ensure that the Chassis ECM remains powered during the flashing step.

Perform the following procedure:

1. If the tire monitoring system was "Not Installed", as part of the check-in Step 4of "Determine the Presence of a Cat Tire Monitoring System", the Tire Monitoring System Software Enabled Attachment will need to be installed, as specified in the procedure below.

   1. Turn the key switch to the "ON" position.

   2. Launch Cat ET 2014A or later on the laptop.

   3. Connect to the machine using Cat ET.

   4. At the ECM selection screen, select the Chassis ECM, and click the "OK" button.

   5. Click the Cat ET configuration icon to access the "Configuration Parameter" page.

   6. Select the "Tire Monitoring System Installations" menu item.

   8. If prompted, obtain the necessary factory passwords to install the software enabled attachment. Then click "OK".

      Note: The passwords shown in Illustration 29 are only an example, and will not work on an actual machine.

      Note: An SEA password is not required for 793F CMD (S/N: RBT) machines. Contact your Cat Technical Communicator (TC) for more support.

   9. After the "Tire Monitoring System Installation Status" is set to "Installed", turn the key switch to the OFF position, and wait 30 seconds.

   10. Turn the key switch to the ON position.

       The chassis will attempt to detect automatically whether communication is with a Cat tire monitoring receiver or a third-party interface ECM. This procedure should take between 12 and 25 seconds. After the chassis has detected the tire monitoring receiver, the backup alarm will sound for a two second interval. This action will indicate that the chassis successfully detected a receiver.

   11. After the backup alarm has sounded for the two second interval, turn the key switch to the OFF position. Wait 30 seconds and turn the key switch back to the ON position. The installation process is now complete. The user should now be able to monitor all the available tire monitoring system temperatures, pressure, and events through the monitor display, Cat ET, and the VIMS web interface.

Troubleshooting

If the chassis ECM is unable to detect a Cat tire monitoring receiver or a third-party interface tire monitor ECM, a "3473-9" diagnostic ("Tire Monitoring Module: Abnormal Update Rate") will be created after a 3 minutes interval for TyreSense or 11 minutes interval for B-Tag interface. If the diagnostic occurs, perform the following troubleshooting steps:

• Check the CAN wiring to ensure the health interface module ECM (depending on installation type) is wired correctly to the required CAN bus.

• Check to ensure that the software has been installed correctly on the health interface module ECM. Also, verify that the configuration file has been uploaded to that ECM.

• Check to ensure that the health interface module ECM is connected to the third-party tire monitoring receiver over the correct serial port link. Also, verify that the serial port is wired correctly to the third-party tire monitoring ECM.

• Check to ensure that the third-party tire monitoring receiver is configured to communicate over a serial port to the health interface module ECM.

Operation

Refer to Systems Operation, UENR3676, "Health Interface Module Setup and Configuration Guide" for details on the operation of the health interface module graphical user interface.

User Interface

The "INTERFACE" menu tab is provided to view the tire monitoring system information.

Note: The user interface for the health interface module is only accessed for troubleshooting purposes.

The "INTERFACE" page consists of the following menu items:

• "System Parameters" (TyreSense only)

• "Statistics"

• "Tire Parameters"

• "Tire Events"

• "General Events"

"Statistics"

Illustration 32	g03146850
"Statistics" page

The "Statistics" page provides statistics about the TyreSense data link. The following data is displayed:

"Rx Count" - This value is the number of valid messages that have been received by the health interface module from the machine unit since the last reset.

"Tx Count" - This value is the number of messages that have been sent from the health interface module to the machine since the last reset.

"Rx Error Count" - This value is the number of messages that could not be received by the health interface module from the machine unit since the last reset.

"Tx Error Count" - This value is the number of messages that could not be sent from the health interface module to the machine unit since the last reset.

Note: The "Tx Error Count" value should remain 0. The "Statistics" page displays a default value of 0 for all parameters when the ECM is powered OFF/ON. When data is exchanged between the health interface module and the machine unit, the appropriate count increments by one. If the machine unit stops sending data to the health interface module, the previous values that were displayed remain displayed on the web page. The statistic values are only reset back to 0 if the ECM is power cycled, or the "Clear" button is pressed.
