(1) Integrated Sensing Module (ISM) data linkIf Cat® Electronic Technician (ET) will not communicate with the ECM, refer to Troubleshooting, "Electronic Service Tool Does Not Communicate" before you begin this procedure. The procedure will verify that electrical power is being supplied to the ECM and to the service tool connector.The data links are used to communicate information between the engine ECM and other control modules that are a part of the application. Cat ET also communicates with the ECM via the data links.The service tool connector contains connections for electrical power and for the data links.Cat ET may display the following error message:"The version of the ECM is not recognized and the integrity of the changed parameters and displayed data is not guaranteed."This message indicates one of the following conditions:
The flash file in the ECM is newer than the version of Cat ET.
The latest version of Cat ET has not been installed.

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Determine if a code is active or logged.
Codes
Result: A -9 code is active or logged.
Proceed to Test Step 2.
2. Check the Part Number of the Affected Component
A. Verify that the part number of the affected component is the correct part number for the application.
Part Number
Result: The part number is correct for the application.
Proceed to Test Step 3.
Result: The part number is not correct for the application.
Repair: Replace the affected component with the correct part number for the application.
Proceed to Test Step 6.
3. Ensure that the latest Flash File Software is Installed in the ECM
A. Connect Cat ET.
B. Use Cat ET to verify that the correct flash file is being used.
Note: Some devices on the data link may not be reflashed. If the device cannot be reflashed, the device must be replaced.
Flash File
Result: The latest flash file is installed.
Proceed to Test Step 6.
Result: The latest flash file is not installed.
Repair: Perform the following procedure:
1. Download the latest flash file from SIS Web.
2. Install the software into the ECM.
Refer to Troubleshooting, "ECM Software - Install" for additional information.
If the problem is not resolved, proceed to Test Step 6.
4. Check for Battery Voltage at the Affected Component
A. Turn the power to the ON position.
B. Measure the voltage between the following terminals on the wiring harness connector for the affected component:
- Battery (+) and Battery (-)
Battery Voltage
Result: There was battery voltage between the battery (+) and battery (-) terminals at the wiring harness connector.
Proceed to Test Step 5.
Result: There was not battery voltage between the battery (+) and battery (-) terminals at the wiring harness connector. There is an open or a short in the wiring harness.
Repair: Repair or replace the wiring harness.
Proceed to Test Step 6.
5. Check the Termination Resistors for the J1939 Data Link
A. Turn the main disconnect switch to the OFF position.
B. At the affected component, measure the resistance between the following CAN data link terminals:
- CAN (+) and CAN (-)
60 10 Ohms
Result: The resistance is less than 50 Ohms. There are more than 2 termination resistors installed in the wiring harness or a short circuit has been detected.
Repair: Repair or replace damaged components.
Proceed to Test Step 6.
Result: The resistance is 60 10 Ohms. The termination resistors are OK.
Proceed to Test Step 6.
Result: The resistance is approximately 120 10 Ohms. There is a problem with a termination resistor or a termination resistor is missing.
Repair: Check the resistance on each terminating resistor. Replace the failed termination resistor.
Proceed to Test Step 6.
Result: The resistance is greater than 130 ohms. There is a problem with the wiring harness between the ECM and the next connection point in the data link wiring.
Repair: Repair or replace the wiring harness.
Proceed to Test Step 6.
6. Check for Active CAN Communication
A. Connect Cat ET.
B. Use Cat ET to monitor the following:
- Codes
Codes
Result: A code is not active.
Return to service.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
