Bluetooth Operator ID and Machine Security System (MSS) Caterpillar

Machine ECM 1

The following is a list of Diagnostic Trouble Codes (DTCs) associated with the bluetooth transceiver of the machine.

Each CAN data link circuit is an input and output of select electronic control modules. The data link is designed to carry communications between the electronic control modules.

Possible Causes for an FMI 9 Diagnostic code are:

• CAN harness wiring failure.

• Connector failure.

• Transceiver failure.

Note: A loss of power in the system to an ECM can cause the ECM to activate this diagnostic code combination. Ensure that ECM modules with this diagnostic code are powered up before proceeding with this procedure.

The FMI 9 code means that the ECM has lost all communication with another control module.

The preceding diagram is a simplified schematic of the data link connections. The schematic is electrically correct. However, not all the possible harness connectors are shown. Refer to the latest revision of the Electrical Schematic to view the entire circuitry of the machine.

Diagnostic Trouble Code Procedure

Prior to beginning this procedure, inspect the harness connectors involved in this circuit. Poor connections are often the cause of problems in an electrical circuit. Verify that all connections in the circuit are clean, secure, and in good condition. Check the wiring for pinch points or abrasions. Look for and repair areas where wires are exposed. If a problem with a connection is found, correct the problem. Verify that this diagnostic code is active before performing a troubleshooting procedure.

1. Identify the active FMI code associated with the components.

2. Determine which code is present and use the list below to determine which procedure to follow.

• FMI 9 Diagnostic code, proceed to Table 2.

Keys do not Populate in Cat App: Fleet Management

1. Check that the MDID in the keys tab of the Cat App: Fleet Management mobile application matches that in Operator Management System (OMS). Ensure that keys were given to that particular user.

2. Check that the key push was done properly and that the update log of that push is completed.

3. Restart the phone and reopen the Cat App: Fleet Management mobile application. Check the keys tab.

Cannot Locate "Security Management" Menu

1. Access the vehicle and connect to the vehicle using Cat^® Electronic Technician (Cat ET).

2. Connect to the Machine Security System (MSS) ECM and go to the configuration page.

3. Find "Security Access Parameters" under the MSS ECM and expand.

4. Locate "Advanced Machine Security System Installation Status" and ensure it is installed.

5. Turn OFF the machine master switch, wait 1 minute, and turn the master switch ON if this status is changed.

6. Move the keyswitch to ON and access Cat ET. Check if the "Security Management" section is available in the Service menu.

Bluetooth Key is not Connecting

1. Check the battery within the keyfob, the battery is CR-2450. Replace the battery if needed.

2. Access the vehicle and connect to the vehicle using Cat ET.

3. Go to configuration, expand the MSS ECM.

   1. Check the "Operator Identification Enable Status" is set to "Enable".

   2. Check the "Operator Management Bluetooth Enable Status" is set to "Enabled".

   3. Check the "Operator Management Passcode Enable Status" is set to "Enabled".

4. Power cycle the machine.

5. Check in Cat ET that there are no diagnostics, especially diagnostics of the form "5874-X". These diagnostics indicates a fault with the Bluetooth transceiver. If the FMI code is 9, proceed through Table 2.

6. Locate the Bluetooth transceiver on the machine. Check that the first three numbers of the serial number are 261 or higher. Any transceiver with a lower value may have a fault and should be replaced.

7. Access WinFlash in Cat ET and check the current software of the Bluetooth transceiver (CATBTNT). Check that the software is up to date, install new software if the software is not up to date.

8. Select "Service", then select "Security Management" at the bottom of the new screen. Click the "View Secure Data" button.

9. Enter the factory password or login with a master level account.

   The current keylist should be displayed.

10. Locate the corresponding keyfob in the list. If the keyfob is not present, refer to the Testing and Adjusting , Key - Program section of this manual.

11. Ensure that the MAC address on the key and the password field for the Bluetooth device in Cat ET match.

12. Download a Bluetooth scanner app.

13. Remove or power down all Bluetooth devices from the immediate vicinity of the vehicle except for the phone running the Bluetooth scanner.

14. Turn ON the vehicle in manual, it is not necessary to crank the engine. Turn OFF any other vehicle in the area. Enter the cab of the vehicle.

15. Start the Bluetooth scanner. Look for a device named either the serial number of the vehicle or CATBTNT. If one of these is found, the vehicle Bluetooth transceiver is operating as intended.

16. Leave the cab with the app still running, go to the key that is not synching. In the app look for the MAC address on the key, it should also be named "KEYFOB". If it is found, then the key is operating as intended.

ECM Replacement if there is ECM Failure

Before completing the ECM replacements, first attempt all other troubleshooting methods associated with the symptom presented. Then attempt to take a machine Product Status Report (PSR), a Fleet/Key Configuration copy, and an ECM configuration copy. Assuming there are not copies already.

Creating a PSR

1. Start Cat ET.

2. Click "Information" in the title bar.

3. Click "Product Status Report".
   Show/hide table

   Illustration 1	g06411974
   PSR

4. Click the "Select All" button in the new window toward the bottom of the screen. Refer to Illustration 1.

5. Click "Create Report" at the bottom left of the window, refer to Illustration 1. Wait for the report to finish. Do not click "Cancel" unless no progress is made in 30 minutes.

   Note:  Messages may appear telling the user that certain data cannot be loaded. Click "OK" at these messages to continue with the PSR. For ECM failure, this notice is normal.

6. A new window will appear, in the bottom right corner click the "Save As" button and save the file to a desired folder.

7. The PSR is pivotal to the Dealer and Dealer Solutions Network (DSN) to identify and resolve issues.

Copying the Fleet/Key Configuration

For the proper way to create copies, refer to the Testing and Adjusting , Configuration section of this manual.

For ECM Copy

1. Go to "Services".

2. Go to "Copy Configuration" then to "ECM Replacement".

3. Click "Yes" on the status message.

4. Select the ECM that has failed and press "OK". Allow the file to finish loading. Do not press "Cancel" unless no progress is made in 15 minutes.

   Note: Messages may appear warning the user that certain information cannot be loaded. Press "OK" on these warnings to continue the process. For a failed ECM, these warnings are normal.

5. Press "OK" when the ECM replacement file is finished. Press the "Save to File" button at the bottom of the Cat ET screen. Save the file to the desired folder.

Software List Creation

1. Connect a comms adapter to the computer and the service port of the machine.

2. Start Cat ET.

3. Connect to the ECM that contains the MSS library/key list.

4. Follow these steps to compile a list of devices/software and the installation status of each prior to the ECM failure. Even if the devices are known, it is useful to check each product to be sure. The devices/software in question are Product Link, MSS, Tamper, and machine immobilizer(s).

   Note: A failed device might not display any information. The owner of the machine may have to find what systems were installed on the ECM through other means.

Flashing an ECM

This procedure will provide a detailed process of flashing an ECM or Router over Ethernet. This flashing process can only be done by the LAN (Local Area Network) side of the device. WAN (Wide Area Network) flashing is not allowed. The Ethernet Device must be powered on by the following:

Machine: Placing the machine into RC Enable then Manual Override with Machine Keyswitch On.

Station: Turning on the Power Converter and Turning the Master Switch On.

Flashing the ECM

Connect the ECM of the Operator Station or Machine to your computer via 538-5051 Communication Adapter Gp.
