WASHER 6J9747 - Caterpillar

The diagnostic code for the special instruction is logged in order to report the configuration status of the data link. The diagnostic code for the special instruction does not check the physical condition of the data link.The following list identifies possible faults on the data link:
Incorrect personality module code
An invalid configuration parameter
Incorrect module or display on the data link
Damaged data link wiring
Incompatible software in the ECM or ISMUse this procedure in order to troubleshoot a diagnostic code for a special instruction. Also, use this procedure if the following diagnostic code is active.

Troubleshooting Test Steps Values Results
1. Check for an Associated -9 Code
A. Establish communication between the electronic service tool and the Electronic Control Module (ECM) for the engine.
B. Download a "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Check for active diagnostic codes.
Associated Code
Result: An associated -9 code is logged.
Repair: Repair all associated -9 codes before continuing with this procedure. Refer to Troubleshooting, "Data Link - Test".
If a -14 code is still present after resolving the -9 code, proceed to Test Step 2.
Result: An associated -9 code is not logged.
Proceed to Test Step 2.
2. Check the Personality Module Code for Compatibility with the Application
A. Connect to the electronic service tool.
B. Select the ECM or ISM connection that is related to the logged code.
C. Check if the personality module code is valid for the application.
Compatible Personality Module
Result: The code is valid for the application.
Proceed to Test Step 3.
Result: The code is not valid for the application.
Repair: Obtain the correct flash file and update the ECM or ISM. Reset all active codes and clear all logged codes. Return the unit to service.
3. Check the Configuration Parameters
A. Check the configuration parameters in order to ensure that the parameters are programmed correctly. Refer to Troubleshooting, "Configuration Parameters".
B. Select the ECM connection that is related to the logged code.
Correct Configuration Parameters
Result: The configuration parameters are programmed correctly.
Proceed to Test Step 4.
Result: The configuration parameters are not programmed correctly.
Repair: Program the parameters to function with the other modules on the data link. Reset all active codes and clear all logged codes. Return the unit to service.
4. Check for Compatibility with the ECM and the ISM on the Data Link
A. Use the as shipped information found in SIS web TMI to determine if any other ECM or display on the data link are incompatible.
B. Select the ECM connection that is related to the logged code.
Compatible ECM and ISM
Result: The ECM and ISM are not compatible.
Repair: Replace the incompatible ECM or ISM with the correct module. Reset all active codes and clear all logged codes. Return the unit to service.
