The Electronic Control Module (ECM) has been powered up for at least five seconds. The Integrated Temperature Sensing Module (ITSM) has sent ten consecutive messages to the ECM via the Cat Data Link. None of the messages have been received by the ECM.
Note: This diagnostic code is logged by the ECM only. This code is not activated or logged by the ITSM. Although there is a failure to communicate with the ECM, the ITSM may still be able to communicate with the Caterpillar Electronic Technician (ET).
System Response:
The alarm output is activated. The code is logged.
Note: If Cat ET cannot communicate with the ITSM, the values for the ITSM "Status Parameter" will display "Unavailable".
Troubleshooting:
Test Step 1. Perform the following diagnostic procedure: "Integrated Temperature Sensing Module (ITSM)"
Results:
- OK - STOP
