CONNECTOR G 0324223 - Caterpillar

ECM connector and the sensor connector that are associated with the active diagnostic code.
Check the screws for the ECM connectors for the correct torque of 5 N m (44 lb in).
Check the harness for abrasions and for pinch points from the sensors back to the ECM.
Use the electronic service tool to perform a "Wiggle Test". The "Wiggle Test" will identify intermittent connections. Expected Result:All connectors, pins, and sockets should be completely coupled and inserted. The harness should be free of corrosion, abrasions and pinch points.Results:
OK - Proceed to Test Step 3.
Not OK - Repair: Repair the connectors or the harness and/or replace the connectors or the harness. Ensure that all of the seals are correctly in place and ensure that the connectors are completely coupled.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 3. Verify that the Diagnostic Code is Still Active
Turn the keyswitch to the ON position. Wait at least 10 seconds for activation of the diagnostic codes.
Use the electronic service tool to check for active diagnostic codes. Record all active diagnostic codes.
Determine if the fault is related to an open circuit diagnostic code or a short circuit diagnostic code. Expected Result:Either a short circuit diagnostic code is active or an open circuit diagnostic code is active.Results:
OK - Short Circuit - A voltage above normal diagnostic code is active at this time. Proceed to Test Step 4.
OK - Open Circuit - A voltage below normal diagnostic code is active at this time. Proceed to Test Step 5.
Not OK - A short circuit diagnostic code is not active. An open circuit diagnostic code is not active. An intermittent fault may exist.Repair: Use the electronic service tool to perform a "Wiggle Test". If faults are indicated then go to the appropriate procedure. STOPTest Step 4. Disconnect The Sensor In Order To Create An Open Circuit
Turn the keyswitch to the OFF position.
Disconnect the sensor connector.
Turn the keyswitch to the ON position. Wait at least 10 seconds for activation of the diagnostic codes.
Use the electronic service tool to check the "Active Diagnostic Code" screen. Check for an open circuit diagnostic code. Expected Result:An open circuit diagnostic code for the sensor is now active.Results:
OK - A voltage above normal diagnostic code was active before disconnecting the sensor. An open circuit diagnostic code became active after disconnecting the sensor. Proceed to Test Step 6.
Not OK - There is a short circuit between the sensor harness connector and the ECM. Leave the sensor disconnected. Proceed to Test Step 8.Test Step 5. Measure the Sensor Supply Voltage
Turn the keyswitch to the OFF position.
Disconnect the sensor from the engine harness.
Turn the keyswitch to the ON position.
Measure the voltage from terminal A to terminal B on the sensor connector. Expected Result:The voltage from terminal A to terminal B measures 4.84 to 5.16 Volts DC.Results:
OK - The sensor supply voltage is correct. Proceed to Test Step 7.
Not OK - The sensor supply voltage
