DT Type sealing plugThe 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 is 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 can not 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 connector bolt is properly tightened. Be careful not to tighten the bolt too much. The bolt may break.
Do not exceed 6.0 N m (53.0 lb in) of torque on the connector bolt of the harness when the connector is being installed on the ECM. Expected Result: The harness connector is secure and the connector bolt of the ECM is properly torqued.Results:OK - The harness connector is secure and the connector is properly torqued. Proceed to test step 3.NOT OK - A problem exists with the connector.Repair: Secure the harness connector of the ECM. Ensure that the connector bolt is properly torqued.STOP.
PERFORM A PULL TEST ON EACH CONNECTOR CONTACT.
Each connector contact should withstand 45 N (10 lb) of pull. Each wire should remain in the connector body. This test checks whether the wire was properly crimped in the contact and whether the contact was properly inserted into the connector.
The DT connectors use an orange wedge to lock the terminals in place.
Check in order to ensure that the orange wedge is not missing and that the orange wedge is installed properly on the DT connectors.Note: A crimp tool should "ALWAYS" be used in order to crimp wires on connector contacts. Do not solder the terminals. Use the proper crimp tool.Expected Result: Each connector contact should withstand 45 N (10 lb) of pull. Each wire remains in the connector body. Results:OK - Each connector contact withstands 45 N (10 lb) of pull. Each wire remains in the connector body. Proceed to test step 4.NOT OK - A problem exists with the connector.Repair: Repair the wiring or replace the connector contact.STOP.
CHECK THE WIRES FOR NICKS OR ABRASIONS IN THE INSULATION.
Carefully inspect each wire for signs of abrasion, nicks, or cuts. The following areas are locations that should be checked:
Exposed insulation
Points of rubbing wire
Check all of the hold down clamps for the harness in order to verify that the harness is properly clamped. Also check all of the hold down clamps for the harness in order to verify that the harness is not compressed by the clamp. Pull back the harness sleeves in order to check for a flattened portion of wire. The flattened portion of wire is caused by the clamp that holds the harness. Expected Result: The wires are free of abrasion, nicks, or cuts and the harness is properly clamped. Results:OK - The wires are free of abrasion, nicks, or cuts and the harness is properly clamped. Proceed to test step 5.NOT OK - A problem exists with the wiring.Repair: Repair the wires or replace the wires, as required.STOP.
CHECK THE CONNECTORS FOR MOISTURE OR CORROSION.
Ensure that the connector seals and the white sealing plugs are in place. If any of the seals or plugs are missing, replace the seal or plug. If necessary, replace the connector.
Check all of the wiring harnesses in order to verify that the harness does not make a sharp bend out of a connector. This will deform the connector seal and this will create a path for the entrance of moisture. Refer to Illustration 1.Note: It is normal to see some minor seal abrasion on the ECM connector seals. Minor seal abrasion will not allow the entry of moisture.
Thoroughly inspect ECM connectors for evidence of moisture entry. If moisture or corrosion is evident in the connector, the source of the moisture entry must be found and the source of the moisture entry must be repaired. If the source of the moisture entry is not repaired, the problem will reoccur. Simply drying the connector will not fix the problem. Likely paths for the entrance of moisture are from missing seals, improperly installed seals, nicks in exposed insulation, and improperly mated connectors.Note: Moisture can also travel from one connector through the inside of a wire to the ECM Connector. If moisture is found in the ECM connector, thoroughly check all connectors and wires on the harness that connect to the ECM. The ECM is not the source of the moisture. Do not replace an ECM if moisture is found in either ECM connector. Note: If corrosion is evident on the contacts or the connector, use only denatured alcohol to remove the corrosion. Use a cotton swab or a soft brush to remove the corrosion. Do not use cleaners that contain trichloroethylene because trichloroethylene may damage the connector.Expected Result: All of the connectors should be completely coupled and all of the seals should be completely inserted. The harness and the wiring should be free of corrosion, moisture, abrasion or pinch points. Results:OK - All of the connectors are comp
