Check the allen head screw on each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the harness and the wiring for abrasion and for pinch points.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted. The harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The harness and wiring appear to be OK. Proceed to Test Step 2.
Not OK - There is a problem in the connectors and/or wiring.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Active Diagnostic Codes
Connect Cat ET to the service tool connector.
Turn the keyswitch to the ON position.
Monitor the "Active Diagnostic Code" screen on Cat ET. Check and record any active diagnostic codes.Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Select diagnostic tests from Cat ET.
Select the "Override Parameters" screen on Cat ET.
Activate the ether override.
Monitor the "Active Diagnostic Code" screen on Cat ET. Check and record any active diagnostic codes.Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Disable the ether override.
Determine if the problem is related to an open circuit diagnostic code -5 or a short circuit diagnostic code -6.Expected Result:No diagnostic codes are active.Results:
OK - No diagnostic codes are active.Repair: The problem may have been related to a faulty connection in the harness. Carefully inspect the connectors and wiring. Refer to Troubleshooting, "Electrical Connectors - Inspect".STOP
Not OK - A short circuit diagnostic code -6 is active at this time. Proceed to Test Step 3.
Not OK - An open circuit diagnostic code -5 is active at this time. Proceed to Test Step 4.Test Step 3. Disconnect the Connector for the Ether Solenoid in Order to Create an Open Circuit
Turn the keyswitch to the OFF position.
Disconnect the connector for the ether solenoid.
Turn the keyswitch to the ON position.
Monitor the "Active Diagnostic Code" screen on Cat ET. Check and record any active diagnostic codes.Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Select diagnostic tests from Cat ET.
Select the "Override Parameters" screen on Cat ET.
Activate the ether override.
Monitor the "Active Diagnostic Code" screen on Cat ET. Check and record any active diagnostic codes.Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Disable the ether override.Expected Result:An open circuit diagnostic code -5 is now active for the ether solenoid.Results:
OK - A short circuit diagnostic code -6 was active before disconnecting the connector. An open circuit diagnostic code -5 became active after disconnecting the connector.Repair: Temporarily connect a new ether solenoid to the harness, but do not install the new ether solenoid. Verify that there are no active diagnostic codes for the ether solenoid. If there are no active diagnostic codes for the ether
