Diagnostic Codes Table
J1939 Code and Description Conditions which Generate the Code System Response
4210-5
Engine Pre-lube Drive : Current Below Normal The Electronic Control Module (ECM) detects an open in the circuit for the prelubrication solenoid valve.
The ECM can only detect this condition when the output driver is not activated. The code is logged.
4210-6
Engine Pre-lube Drive : Current Above Normal The ECM detects a short in the circuit for the prelubrication solenoid valve.
The ECM can only detect this condition when the output driver is activated. The ECM can lubricate the engine before cranking begins. This engine prelubrication is used to increase the life of certain engine parts by lubricating these parts before the starting motor is engaged.There are several configuration parameters that define the operation of the prelubrication system. Prior to troubleshooting problems that are associated with the prelubrication system, check the settings of these parameters. Be sure that you understand the proper operation of the system. The charge pressure status of the prelubrication system may be communicated to several different controllers that are on the application. Depending on the status that is communicated there could be an effect on the engine starting. The following status indicators are communicated over the data link:
"Prelube OFF" or "Prelube disabled"
"Prelube waiting for oil"
"Prelube waiting to fill"
"Perlube ready to start"
"Prelube failed"
"Prelube ready to start"
"Continuous prelube"Some of these status indicators report the parameter settings of the prelubrication system. The ECM determines the charge pressure status via the engine oil pressure sensor.The prelubrication system is activated at ECM powerup. The ECM prevents the starting motor from engaging while the pump builds pressure in the lubrication system.Also, a manual prelube switch may be wired to P1-60 terminal at the primary ECM connector. When this ECM input is connected to battery +, the ECM will activate the prelubrication solenoid valve. Refer to Troubleshooting, "Switch Circuits - Test" for information related to troubleshooting this switch circuit.An override for the prelubrication system is available in Caterpillar Electronic Technician (ET). The override allows the technician to activate the prelubrication system for service and testing. The test is functional only when the engine speed is zero rpm. The test is accessed by selecting the following menus on Cat ET:

Troubleshooting Test Steps Values Results
1. Check for Active Diagnostic Codes and Check for Logged Diagnostic Codes
A. Connect Caterpillar Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Product Status Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note. Wait at least 30 seconds in order for diagnostic codes to become active.
D. Select diagnostic tests from Cat ET.
E. Select the "Override Parameters" screen on Cat ET.
F. Activate the override for the circuit that is being tested.
G. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note: Wait at least 30 seconds in order for the diagnostic code to become active.
H. Deactivate the override.
I. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Logged Diagnostic Codes
Or
Active Diagnostic Codes
677-5
677-6
Results: A diagnostic code is logged but is not active.
Repair: Do not troubleshoot a logged code unless the code relates to an operator complaint. If the code is logged and the code does not relate to an operator complaint, clear the code.
If the logged code relates to this procedure, inspect the electrical connectors and the wiring for the circuit. Refer to Troubleshooting, "Electrical Connectors - Inspect"
Results: A -5 diagnostic code is active at this time.
Proceed to Test Step 2.
Results: A -6 diagnostic code is active at this time.
Proceed to Test Step 5.
2. Inspect the Electrical Connectors and the Wiring
A. Check the harness and the wiring for abrasion and for pinch points.
B. Thoroughly inspect all connectors that are in the circuit. Refer to Troubleshooting, "Electrical Connectors - Inspect " for details.
-5 code
Results: The connectors and wiring are OK.
Proceed to Test Step 3.
Results: The connectors and/or wiring are Not OK.
Repair: Repair the connectors or wiring and/or replace the connectors or wiring.
3. Determine if the Solenoid Valve has an Open Circuit Condition
A. Remove the electrical power from the ECM.
B. Disconnect the electrical connector from the solenoid valve of the circuit being tested.
C. Using appropriate terminals, fabricate a jumper wire and short the harness connector.
D. Restore the electrical power to the ECM.
E. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note. Wait at least 30 seconds in order for the diagnostic codes to become active.
F. Select diagnostic tests from Cat ET.
G. Select the "Override Parameters" screen on Cat ET.
H. Activate the override for the circuit that is being tested.
I. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note: Wait at least 30 seconds in order for the diagnostic code to become active.
J. Deactivate the override.
K. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note: Wait at least 30 seconds in order for the diagnostic code to become active.
L. Remove the electrical power from the ECM.
M. Restore the wiring to the original config
