If a problem is found in the electrical connector, repair the connector and verify that the problem has been corrected.The following background information is related to this procedure:Many of the operational procedures and the diagnostic code procedures in this troubleshooting guide will instruct you to check a specific electrical connector. Intermittent electrical problems are often caused by poor connections. Always check for an active diagnostic code before breaking any connections. Also, always check for an active diagnostic code after the connector is reconnected in order to verify that the problem disappears. Simply disconnecting the connectors and then reconnecting the connectors can temporarily solve a problem at times. If this occurs, likely causes are loose terminals, bent terminals, improperly crimped terminals, corrosion, or harness routing that is improper.The original source of the problem must then be identified in order to ensure that the problem does not reoccur.Follow this procedure to inspect the connectors in order to determine if the connectors are the cause of the problem.

The 8T-8729 Connector Pin (2) and the 8T-8730 Connector Socket (1) is designed to accept only one 16/18 AWG wire. Do not insert multiple wires of a smaller wire size. An incorrect method would be using two 24 AWG wires. The 9W-0852 Connector Pin and the 9W-0844 Connector Socket are designed to accept only one 14 AWG wire. Do not insert multiple wires of a smaller wire size. An example of an incorrect method is the use of two 20 AWG wires.
CHECK THE CONNECTORS.
Ensure that the connector is properly locked. Also, ensure that the two halves of the connector cannot be pulled apart.
Verify that the latch tab of the connector is properly latched. Verify that the latch tab of the connector is fully latched. Expected Result: The connector will securely lock. The connector and the locking mechanism are without cracks or breaks.Results:OK - The connector will securely lock. The connector and the locking mechanism are without cracks or breaks. Proceed to test step 2. NOT OK - A problem exists with the connector.Repair: Repair the connector or replace the connector, as required.STOP.
CHECK THE ALLEN HEAD SCREW ON THE HARNESS CONNECTOR OF THE ECM.
Ensure that the
