Gas substitution shuts off.    Use this procedure to troubleshoot the electrical system if a problem is suspected with the CAN data link or the Cat Data Link.Note: This procedure checks for an open or for a short in the data link circuits.If Caterpillar 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.When the keyswitch is in the OFF position, Cat ET may communicate with the ECM. However, the communications may be disrupted and the communications may require frequent reconnection. In order to avoid this problem, place the keyswitch in the ON position when Cat ET is being used.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. Inspect the Electrical Connectors and the Wiring
Note: Carefully follow this procedure in order to identify an intermittent problem.
A. Perform a visual inspection of the wiring between the P1 and P2 ECM connectors, the termination resistors, and the service tool connector. Also, inspect the wiring and the connectors at various controllers and control boxes.
Look for these problems:
- Harness damage that is caused by chafing
- Harness damage that is caused by excessive heat
- Look for moisture on the wiring and in the connectors.
- Pull on the wires that are associated with the data links.
This test verifies that the wire is properly crimped to the terminal and that the terminal is properly inserted into the connector.
   
Connectors    
Result: The wiring and the connectors appear to be OK.
Proceed to Test Step 2.
Result: There is a problem with the wiring or with a connector.
Repair: the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the connector seals are properly in place and ensure that the connectors are coupled.
Verify that the repair eliminated the problem.
   
2. Bypass the Wiring for the Data Link
A. Connect the 217-0113 Wiring Harness (ECM BYPASS) to the J1 connector, to the 332-7381 Data Link Cable As, and to the battery.
B. Restore the electrical power to the ECM.
C. Try to establish communication between Cat ET and the ECM.
