Inspect Electrical Connectors and Wiring
Turn the keyswitch to the OFF position.
Thoroughly inspect the ECM connector J2/P2. Inspect the injector connectors. Refer to Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the customer connector (allen head screw) for the proper torque of 2.25 0.25 N m (20 2 lb in).
Check the harness and the wiring for abrasion and for pinch points.Expected Result:The connectors and wiring are free of the following problems: damage, corrosion, abrasion and incorrect attachment.Results:
OK - The connectors and wiring are OK. Proceed to Test Step 2.
Not OK - The connectors and/or wiring are not OK.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 2. Check for Active Diagnostic Codes
Connect the electronic service tool to the service tool connector.
Turn the keyswitch to the ON position.
Monitor the active diagnostic code screen on the electronic service tool. Check and record any active diagnostic codes.Note: Wait at least 15 seconds in order for the diagnostic codes to become active.Expected Result:A CID-FMI 1-05 to 16-05 or 1-06 to 16-06 is not active.Results:
OK - A CID-FMI 1-05 to 16-05 or 1-06 to 16-06 is not active. Proceed to Test Step 3.
Not OK - A CID-FMI 1-05 to 16-05 or 1-06 to 16-06 is active. Proceed to Test Step 5.Test Step 3. Perform the Cylinder Cutout Test
Engine power is reduced when a properly functioning cylinder is cut out. Make sure that you will not damage auxiliary or driven equipment if the engine power is suddenly reduced.
Turn the keyswitch to the OFF position.
Turn the circuit breaker for the battery to the OFF position.
Verify that the ECM connector J2/P2 and the injector connectors J4/P4 through J19/P19 are properly connected.
Start Cat ET.
Turn the circuit breaker for the battery to the ON position.
Turn the keyswitch to the ON position.
Start the engine.
Apply a load to the engine.
Use the diagnostic test on Cat ET to initiate the cylinder cutout test.
Check for a difference in the sound, feel, or power of the engine as each cylinder is cut out. The amount of change should be similar for all of the good cylinders. The amount of change should be minimal for a weak cylinder or a bad cylinder.
Disable the override. Repeat the above steps for each cylinder (solenoid).Expected Result:The amount of change is similar for all of the good cylinders. The amount of change is minimal for a weak cylinder or a bad cylinder.Results:
OK - There was a noticeable change in engine performance during the cylinder cutout test.Repair: The change in engine performance indicates that each cylinder is operating correctly. There may be an intermittent problem. If the problem is intermittent, refer to Troubleshooting, "Inspecting Electrical Connectors".STOP
