Disconnecting and reconnecting connectors sometimes resolve intermittent electrical problems. Check for diagnostic codes immediately before disconnecting a connector. Also check for diagnostic codes after reconnecting the connector. If the status of a diagnostic code changed due to disconnecting and reconnecting a connector, the likely reasons are:
Loose terminals
Improperly crimped terminals
Moisture
Corrosion
Inadequate mating of a connectionGuidelines
Use a 1U-5804 Crimp Tool (12-GA TO 18-GA) to service Deutsch connector HD and DT connectors. Never solder the terminals onto the wires. Refer to Tool Operating Manual, SEHS9615, "Servicing Deutsch HD and DT style connectors".
To remove the Terminal Position Assurance TPA, insert a small screwdriver and 147-6456 Wedge Removal Tool into each of the slots on the long sides of the connector. Grasp the TPA and pull the TPA away from the plug body.
If a wire is cut, always install a new terminal for the repair.
Do not probe through the wire seals using spoons for troubleshooting. Using probes on the connector will damage the seals. Use the 416-1027 Harness As to troubleshoot the connector.DRCP 80/86 Pin Connector Installation
Insure that the TPA device is correctly installed on the plug body. There should not be any gaps between the plug seal and the TPA.
Place the DRCP connector into the correct receptacle. The connectors are keyed to aid in the assembly to insure correct orientation.
Use a 4 mm (0.16 inch) internal hex drive to tighten the jack screw to a torque of 6 1 N m (4 1 lb ft).
Install the required covers, wire ties and/or supporting devices.Tests
Check the Jack Screw for Proper Installation
Illustration 1 g03583897
Verify that the jack screw has been properly tightened.
Using a 4 mm (0.16 inch) internal hex drive, turn the jack screw counter-clockwise to loosen the connector.
Uninstall the connector.
Inspect the threads on the jack screw for damage. Insure that the retention washer on the mating side of the connector is not damaged.
Reinstall the connector using the 4 mm (0.16 inch) internal hex drive.
Tighten the jack screw to 6 1 N m (4 1 lb ft).Check the Connectors for Moisture and Corrosion
Illustration 2 g03583899The DRCP 80/86 Pin Connector has a seal around the base of the TPA device on the mating plug. This replaceable seal helps prevent moisture and dirt from entering the connector.
Inspect all wiring harnesses. Ensure that the routing of the wiring harness allows the wires to enter the face of each connector at a perpendicular angle. Otherwise, the wire will deform the seal bore. This deformation will create a path for the entrance of moisture. Verify that the seals for the wires are sealing correctly.
Disconnect the suspect connector and inspect the connector seal. Ensure that the
