Test Step 1. Check the Locking of the DT Connector (Deutsch) and Check the Lock Ring of the HD Style Connector (Deutsch)
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. Also verify that the latch tab of the connector returns to the locked position. Expected Result:The connector will securely lock. The connector and the locking mechanism are without cracks or breaks.Results:
OK - Proceed to Test Step 2.
Not OK - Repair: Repair the connector or replace the connector, as required.Verify that the repair eliminates the problem.STOPTest Step 2. Check the Allen Head Screw on the Connector for the Electronic Control Module (ECM)
Ensure that the allen head screw is properly tightened. Be careful not to overtighten the screw and break the screw.
Do not exceed 2.25 N m (20 lb in) of torque on the allen head 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 Terminal Connection
Each terminal and each connector should easily withstand 45 N (10 lb) of pull and each wire should remain in the connector body. This test checks whether the wire was properly crimped in the terminal and whether the terminal was properly inserted into the connector.
The DT connectors use a green wedge to lock the terminals in place. Ensure that the green wedge is not missing and that the green wedge is installed properly on the DT connectors. Note: Terminals should always be crimped onto the wires by using a crimp tool. Do not solder terminals. Use the 1U-5804 Crimp Tool.Expected Result:Each terminal and each connector easily withstands 45 N (10 lb) of pull and each wire remains in the connector body.Results:
OK - Proceed to Test Step 4.
Not OK - Repair: Repair the circuit.Verify that the repair eliminates the problem.STOPTest Step 4. Perform the "Wiggle Test" on the Caterpillar Electronic Technician (ET)
Select the "Wiggle Test" from the diagnostic tests on Cat ET.
Press the "OK" button after you adhere to the warning.
Choose the appropriate group of parameters to monitor.
Press the "Start" button. Wiggle the wiring harness in order to reproduce intermittent problems.
If an intermittent problem exists, the status will be highlighted and an audible beep will be heard. Expected Result:No intermittent problems were indicated during the "Wiggle Test".Results:
OK - Proceed to Test Step 5.
Not OK - Repair: Repair the circuit.Verify that the repair eliminates the problem.STOPTest Step 5. Check Wires for Nicks or Abrasion 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 against the engine
Points of rubbing wire against a sharp point
Check all of
