Configurations of the harnesses for self testThe 7X-1570 Data Link Cable As is cancelled and replaced by the 140-9442 Adapter Cable As . (A) DDT (B) Cat ET
Refer to Illustration 1. Connect the harnesses according to the configuration that is appropriate for the electronic service tool.Note: Leave connector "C" disconnected.
Restore the electrical power to the engine.
Set the engine control to the "STOP" mode.
Verify that the service tool is communicating with the EIS control module.Note: Disregard any diagnostic codes. Clear the codes after you complete this entire procedure.Expected Result:The electronic service tool is communicating with the EIS control module.Results:
OK - The electronic service tool is communicating with the EIS control module. Proceed to Test Step 3.
Not OK - The electronic service tool is not communication with the EIS control module.Repair: Perform the following procedure:
Verify that the harnesses are configured correctly.
Verify that the electronic service tool is receiving electrical power. Refer to Troubleshooting, "Electrical Power Supply".
If the problem persists, connect the harnesses to a different engine. Verify that the harnesses are not the source of the problem. Refer to Troubleshooting, "Electronic Service Tool Will Not Communicate with ECM", if necessary.STOPTest Step 3. Perform Test A
Prepare the electronic service tool for the self test.
For the DDT, scroll to menu 49. The screen on the DDT will display "PRESS <ALT 1> KEY".
For Cat ET, click on the "Diagnostics" menu. Then select "Diagnostic Tests" from the drop-down menu. Then select "ECM Self Test". Cat ET will display the conditions that are required in order to begin the test.
Connect connector "A" to connector "C".
Initiate test A by performing the action that is appropriate for the electronic service tool.
For the DDT, press the "ALT1" key.
For Cat ET, click on the "Start" button.Expected Result:The electronic service tool indicates that test A is in progress. When test A is complete, the electronic service tool will display a prompt.Results:
OK - The control module successfully completes test A. Proceed to Test Step 4.
Not OK - The control module fails test A. The electronic service tool indicates the failure. Proceed to Test Step 5.Test Step 4. Perform Test BNote: Connector "B" must be connected to connector "C" within five minutes or the self test will fail. If this occurs, restart the self test from "Test Step 3. Perform Test A".
Disconnect connector "A" from connector "C".Note: Wait for three seconds after connector "B" is connected to connector "C". Test B will begin automatically.
Connect connector "B" to connector "C".Expected Result:The electronic service tool indicates that test B is in progress. When test B is complete, the electronic service tool indicates that the self test was successful.Results:
OK - The EIS control module successfully completes test B.Repair: Perform the following procedure:
Set the engine control to the "OFF/RESET" mode.
Remove the electrical power from the engine.
Disconnect the test harness from the EIS control module.
Connect the engine harness to the EIS control module.
Restore the electrical power to the engine.
Clear any diagnostic codes. If a different test procedure directed you to this self test, return to that procedure.STOP
Not OK - The EIS control module fails the test. The electronic service tool indicates the failure. Proceed to Test Step 5.Test Step 5. Identify the Fault for the EIS Control Module
Identify the fault that is displayed on the electronic service tool.
Refer to Table 1. Perform the corrective action that applies to the code.
