Information:
System Operation Description:Many of the troubleshooting procedures direct you to a specific electrical connector. Use the following test steps to help determine whether the connector is the cause of the problem. If a problem is found in a connector, repair the connector and verify that the problem is corrected.Intermittent electrical problems are often caused by poor connections. Always check for an active diagnostic code before you open any connection. Immediately after you reconnect the connector, check for codes again. Sometimes, simply disconnecting a connector and then reconnecting the connector can solve a problem. If this occurs, the following conditions are likely causes:
Loose terminals
Bent terminals
Improperly crimped terminals
Improperly mated connectors
Moisture
Corrosion

MS connectors
The MS connectors have a metal housing. The pins and the sockets are soldered to the electrical wires. The solder connections are usually protected by a chemical potting which prevents access to the solder point.

Deutsch connectors
Deutsch connectors have a plastic housing. The pins and the sockets are crimped onto the electrical wires. The connector has a locking mechanism in order to hold the pins and the sockets. These connectors are repairable without cutting the wires.

70-pin connector for the ECM
Use the following test steps in order to thoroughly inspect the connectors and determine if the connectors are the cause of the problem.Test Step 1. Check the Connectors
Always set the engine control to the OFF/RESET mode before you inspect electrical conductors. Remove the electrical power from the engine.
For the MS connectors, make sure that the receptacle is turned fully in the clockwise direction. Check that the threading is properly aligned and securely mated.
For the Deutsch HD connectors, make sure that the plug and the receptacle are aligned properly with the index markings. Make sure that the receptacle is turned fully in the clockwise direction. Verify that the receptacle is clicked into the locked position. Make sure that the two halves cannot be pulled apart.
For the Deutsch DT style, make sure that the orange wedge is used in order to lock the pins. Check that the receptacle has clicked into the locked position. Make sure that the two halves cannot be pulled apart. Expected Result:All connectors are properly mated and free of damage.Results:
OK - Proceed to test step 2.
Not OK - Repair: Repair the connectors and/or replace the connectors. Reconnect all of the connectors.STOPTest Step 2. Check the Allen Head Screw on the ECM Connector
Ensure that the Allen head screw is properly tightened. Be careful not to overtighten the screw and break the screw.
When you connect the 70-pin connector to the Electronic Control Module (ECM), do not exceed 6 1 N m (55 9 lb in) of torque on the screw. Expected Result:The ECM connector is secure and the Allen head screw is properly torqued.Results:
OK - Proceed to Test Step 3.
Not OK - Repair: Repair the connector or replace the connector, as required.Verify that the repair eliminates the problem.STOPTest Step 3. Perform a Pull Test on Each Wire Connection
Each terminal and each connector should easily withstand 45 N
