Troubleshooting Test Steps Values Results
4. Perform a Pull Test on Each Wire Terminal Connection
A. 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.
B. 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.
Pull test OK Result: A wire has been pulled from a terminal or a terminal has been pulled from the connector in the 45 N (10 lb) pull test.
Repair: Use the 1U-5804 Crimp Tool to replace the terminal. Replace damaged connectors, as required.
Use the electronic service tool to clear all logged diagnostic codes and then verify that the repair eliminates the fault.
Result: All terminals pass the pull test.
Proceed to Test Step 5.
5. Check the Locking Mechanism of the Connectors
A. Ensure that the connectors lock correctly. After locking the connectors, ensure that the two halves cannot be pulled apart.
B. 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.
The connectors are locked and are not damaged
Result: The locking mechanism for the connector is damaged or missing.
Repair: Repair the connector or replace the connector, as required.
Use the electronic service tool to clear all logged diagnostic codes and then verify that the repair eliminates the fault.
Result: The connectors are in good condition.
Proceed to Test Step 6.
6. Check the Screws on the ECM Connectors
A. Visually inspect the screws for the ECM connectors. Ensure that the threads on each screw are not damaged.
B. Connect the ECM connectors.
C. Use a 7 mm screw to retain each of the ECM connectors.
D. Tighten the two screws for the ECM connector to the correct torque of 6.0 N m (53 lb in).
The ECM connectors are secure.
Result: The screws for the ECM connectors are damaged or a threaded hole in the ECM is damaged.
Repair: Repair the connectors or replace the connectors or screws, as required. If a threaded hole in the ECM is damaged, replace the ECM.
Use the electronic service tool to clear all logged diagnostic codes and then verify that the repair eliminates the fault.
Result: The ECM connectors are secured.
Proceed to Test Step 7.
7. Perform the "Wiggle Test" on the Electronic Service Tool
A. Select the "Wiggle Test" from the diagnostic tests on the electronic service tool.
B. Choose the appropriate group of parameters to monitor.
C. Press the "Start" button. Wiggle the wiring harness to reproduce intermittent faults.
If an intermittent fault exists, the status will be highlighted and an audible beep will be heard.
Intermittent faults were indicated.
Result: No intermittent faults were found.
