SLIP JOINT GP 1714695 - Caterpillar

Perform a 45 N (10 lb) pull test on each of the wires in the sensor connector and the ECM connector that are associated with the active diagnostic code.
Verify that the latch tab of the connector is properly latched.
Check the allen head screw on the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the harness and wiring for abrasions and for pinch points from the sensor to the ECM.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 connectors and wiring are 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 Caterpillar Electronic Technician (ET) to the service tool connector.
Turn the keyswitch to the ON position.
Check for active diagnostic codes Cat ET. Record any active diagnostic codes.Note: Wait at least 15 seconds in order for the diagnostic codes to become active.
Determine if the problem is related to an open circuit diagnostic code -03 or a short circuit diagnostic code -04.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 reinspect the connectors and wiring. Refer to Troubleshooting, "Electrical Connectors - Inspect" for additional information.STOP
Not OK - A short circuit diagnostic code -04 is active at this time. Proceed to Test Step 3.
Not OK - An open circuit diagnostic code -03 is active at this time. Proceed to Test Step 4.Test Step 3. Disconnect the Suspect Sensor in Order to Create an Open Circuit
Turn the keyswitch to the OFF position.
Disconnect the suspect sensor from the harness at the sensor connector.
Turn the keyswitch to the ON position. Wait at least 15 seconds for activation of the diagnostic codes.
Check Cat ET for an active open circuit diagnostic code -03 for the suspect sensor.
Turn the keyswitch to the OFF position.Expected Result:An open circuit diagnostic code -03 is now active for the suspect sensor.Results:
OK - A short circuit diagnostic code -04 was active before disconnecting the sensor. An open circuit diagnostic code -03 became active after disconnecting the sensor.Repair: Temporarily connect a new sensor to the harness, but do not install the new sensor in the engine. Verify that there are no active diagnostic codes for the sensor. If there are no active diagnostic codes for the sensor, permanently install the new sensor. Clear any logged diagnostic codes.Verify that the repair eliminates the problem.STOP
Not OK - The short circuit diagnostic code -04 is still present. The short circuit is between the sensor harness connector and the ECM. Leave the sensor disconnected. Proceed to Test Step 7.Test Step 4. Check the
