Illustration 4 g01042439
Schematic diagram of the Cat Data LinkThe engine is configured for Canadian Standards Association (CSA). The engine is equipped with an optional remote control panel with air/fuel ratio control.Test Step 1. Determine the Fault Code
Connect an electronic service tool to the service tool connector.
Look for the following diagnostic codes:
329-11 Communication Fault with Cat A/F Ratio Control
560-02 Cat Data Link fault
770-09 Cat Data Link #2 communicationsResults:
329-11 Code - Proceed to Test Step 2.
560-02 Code - Proceed to Test Step 2.
770-09 Code - Proceed to Test Step 14.Test Step 2. Inspect the Electrical Connectors and Wiring
Set the engine control to the OFF/RESET mode. Remove the electrical power from the engine.Note: For the following steps, refer to Troubleshooting, "Inspecting Electrical Connectors".
Thoroughly inspect each of the following connectors:
Connectors for the EIS control module
Connectors on the ECM (if equipped)
The service tool connectors
The connectors on the harnesses for the service tool

Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit for the Cat Data Link.
Check the terminal strips for corrosion and for mechanical failure.
Check the harnesses and the wiring for abrasion and for pinch points.Expected Result:The connectors, pins, and sockets are connected properly. The terminal strips do not have corrosion or mechanical failure. The connectors and the wiring do not have corrosion, abrasion, or pinch points.Results:
OK - The components are in good condition with proper connections. If you are using the DDT, proceed to Test Step 3. If you are using the Cat ET, proceed to Test Step 5.
Not OK - The components are not in good condition and/or at least one connection is improper.Repair: Perform the necessary repairs and/or replace parts, if necessary.STOPTest Step 3. Check the Software Program Module (SPM) for the DDT
Verify that the SPM that is installed in the DDT is correct for the application. Refer to Tool Operating Manual, SEHS8806 for the correct procedure.Expected Result:The SPM is correct for the application.Results:
OK - The SPM is correct for the application. Proceed to Test Step 4.
Not OK - The SPM is not correct for the application.Repair: Install the correct SPM into the DDT. Verify that the problem is resolved.STOPTest Step 4. Check the DDT for a Diagnostic FaultNote: The DDT provides indications for the following conditions: incompatible software, internal failures and programming errors. These faults are displayed on the DDT.
Connect the DDT to a service tool connector.
Restore electrical power to the engine.
Look for the diagnostic faults that are listed in Table 1. The code for the fault will be displayed on the DDT.
