A typical example of the lock wedge.
(1) Lock wedge
Ensure that the locking wedge for the connector is installed correctly. Terminals cannot be retained inside the connector if the locking wedge is not installed correctly.
Perform the 45 N (10 lb) pull test on each wire. Each terminal and each connector should easily withstand 45 N (10 lb) of tension and each wire should remain in the connector body. This test checks whether the wire was correctly crimped in the terminal and whether the terminal was correctly inserted into the connector. Expected Result:Each terminal and each connector easily withstands 45 N (10 lb) of pull and each wire remains in the connector body.Results:
OK - All terminals pass the pull test. Proceed to Test Step 5.
Not OK - A wire has been pulled from a terminal or a terminal has been pulled from the connector.Repair: Use the 1U-5804 Crimp Tool to replace the terminal. Replace damaged connectors, as required.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 5. Check Individual Pin Retention into the Socket

Diagram for testing pin retention
Verify that the sockets provide good retention for the pins. Insert a new pin into each socket one at a time in order to check for a good grip on the pin by the socket. Expected Result:The sockets provide good retention for the new pin.Results:
OK - The terminals are OK. Proceed to Test Step 6.
Not OK - Terminals are damaged.Repair: Use the 1U-5804 Crimp Tool to replace the damaged terminals. Verify that the repair eliminates the problem.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 6. Check the Locking Mechanism of the Connectors
Ensure that the connectors lock correctly. After locking the connectors, ensure that the two halves cannot be pulled apart.
Verify that the latch tab of the connector is correctly latched. Also verify that the latch tab of the connector returns to the locked position. Expected Result:The connector is securely locked. The connector and the locking mechanism are without cracks or breaks.Results:
OK - The connectors are in good repair. Proceed to Test Step 7.
Not OK - The locking mechanism for the connectoris damaged or missing.Repair: Repair the connector or replace the connector, as required.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 7. Check the Screws on the ECM Connectors (64 way)Visually inspect the screws for the ECM connectors. Ensure that the threads on each screw are not damaged.
Connect the ECM connectors.
Use a 7 mm Torx screw in order to retain each of the ECM connectors.
Tighten the two Torx screws for the ECM connector to the correct torque of 5.0 1.0 N m (44 9 lb in). Expected Result:The ECM connectors are secure and the Torx screws are correctly torqued.Results:
OK - The ECM connectors are
