Troubleshooting Test Steps	Values	Results
1. Check for an Associated -9 Code A. Establish communication between the Cat^® Electronic Technician (ET) and the engine Electronic Control Module (ECM). B. Download the "Product Summary Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes. C. Check the report for a -9 code that is associated to the special instruction that is logged.	A -9 Code	Result: An associated -9 code is not logged. Proceed to Test Step 2. 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.
2. Check the Personality Module Code for Compatibility with the Application A. Connect the appropriate ECM to Cat ET. B. Select the ECM connection that is related to the logged code. C. Check if the personality module code is valid for the application.	Personality Module Code	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. Clear all logged codes and return to service. If the problem is not resolved, proceed to Test Step 3.
3. Check the Configuration Parameters A. Check the configuration parameters in order to ensure that the parameters are programmed correctly.	Configuration Parameters	Result: The parameters are programmed correctly. Proceed to Test Step 4. Result: Program the parameter(s) to function with the other modules on the data link. Clear all logged codes and return to service. Verify that the repair eliminated the problem.
4. Check for Incompatible Control Groups on the Data Link A. Obtain the engine's "As Shipped" data in TMI. B. Check the parts breakdown for the part numbers of the control groups and the monitor groups that are on the data link. C. Confirm that the control groups that are installed on the data link are compatible with the part numbers from the parts breakdown in TMI.	Incompatible Control Groups	Results: One or more control groups are incompatible. Repair: Replace the control group with a control module that is compatible. Verify that the problem has been resolved. Verify that the repair eliminated the problem.
