4210-5 Engine Pre-lube Drive : Current Below Normal The engine Electronic Control Module (ECM) detects an open in the circuit for the prelubrication relay.
The ECM detects a short to battery voltage in the circuit for the prelubrication relay. The code is logged.
4210-6 Engine Pre-lube Drive : Current Above Normal The ECM detects a short in the circuit for the prelubrication relay. The ECM can automatically lubricate the engine before cranking. The lubrication may 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"
"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 engine lubrication system.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:

Perform a 45 N (10 lb) pull test on each of the wires in the ECM connectors and the other connections that are associated with the circuit.
Check the allen head screw for each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Check the harness and the wiring for abrasion and for pinch points. Expected Result:All connectors, pins, and sockets are coupled and/or inserted. The harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The connectors and wiring appear to be OK. Proceed to Test Step 2.
Not OK - There is a problem in the connectors and/or wiring.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Active Diagnostic Codes
