16 Cylinder EngineTest Step 1. Check for Connector Damage.
Turn the circuit breaker for the battery to the OFF position.
Turn the keyswitch to the OFF position.
Disconnect the main power.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other 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 pinch points.Expected Result:The connectors and wiring should be free of the following problems: damage, corrosion, abrasion and incorrect attachment.Results:
OK - The connectors and wiring are okay. Proceed to test step 2.
Not OK - The connectors and/or wiring are not okay.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Stop.Test Step 2. Check for LOGGED Diagnostic Codes.
Connect the ET.
Turn the circuit breaker for the battery to the ON position.
Turn the keyswitch to the STOP position.
Observe the diagnostic codes on the ET.Expected Result:A CID-FMI 1-05 to 16-05 or 1-06 to 16-06 should not be logged.Results:
OK - A CID-FMI 1-05 to 16-05 or 1-06 to 16-06 is not logged. Logged diagnostic codes are not present. Proceed to test step 3.
Not OK - A CID-FMI 1-05 to 16-05 or 1-06 to 16-06 is logged. There are logged diagnostic codes. 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/RESET 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.
Turn the circuit breaker for the battery to the ON position.
Install the ET.
Start the engine.
Apply a load to the engine.
Use the diagnostic test on the 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 should be similar for all of the good cylinders. The amount of change should be 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 cylinders are working properly. Stop.
Not OK - There was no noticeable change in engine performance during the cylinder cutout test. Proceed to test step 4.Test Step 4. Check the Adjustment of the Fuel Injector and of the Engine Valve Lash Setting.
Turn the keyswitch to the OFF/RESET position.
Turn the circuit breaker for the battery to the OFF position.
Check the adjustment of the fuel injector and of the engine valve lash setting. Refer to the Systems Operation, "Testing and Adjusting".Expected Result:The engine valve lash setting should be correct. The injectors should be okay.Results:
OK - The engine valve lash setting is correct.Repair: The injectors are okay. Check for any diagnostic codes. Stop.
Not OK - The engine valve lash setting is not correct. The injectors are not okay. A problem is found with the injector.Repair: Adjust the engine valve lash. Refer to the Systems Operation, "Testing and Adjusting". Repair the injector. If the problem is still present, replace the injector. If the new injector has a 4 Digit code that is different from the old injector, change the code in the ECM. Stop.Test Step 5. Check the Resistance of the Harness from the Solenoid to the ECM Connector.
This engine uses high voltage to control the fuel injectors.Disconnect electronic fuel injector enable circuit connector to prevent personal injury.Do not come in contact with the fuel injector terminals while the engine is running.
Turn the keyswitch to the OFF/RESET position.
Turn the circuit breaker for the battery to the OFF position.
Disconnect ECM connector J2/P2 and the injector connectors J4/P4 through J19/P19.
Measure the resistance at the ECM connector P2 between the power output for the individual solenoid and the solenoid return. For the eight cylinder engine, refer to Illustration 1. For the sixteen cylinder engine, refer to Illustration 2.Expected Result:The resistance should be greater than 20,000 Ohms.Results:
OK - The resistance was greater than 20,000 Ohms. Proceed to test step 6.
Not OK - The resistance was less than 20,000 Ohms.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Stop.Test Step 6. Check for a Short Circuit from the Harness to the Engine Ground.
This engine uses high voltage to control the fuel injectors.Disconnect electronic fuel injector enable circuit connector to prevent personal injury.Do not come in contact with the fuel injector terminals while the engine is running.
For the 3508B, measure the resistance between the following sockets at ECM connector P2 and the engine ground: P2-16, P2-5, P2-32, P2-26, P2-11, P2-38, P2-37, P2-27, P2-30, P2-31, P2-39 and P2-36.
For the 3516B engine, measure the resi
