Diagnostic Codes Table
Description Conditions which Generate this Code System Response
338-5 Engine Pre-Lube Pump Relay current below normal The engine's Electronic Control Module (ECM) detects an open circuit at the prelube relay.
The ECM detects a short to battery voltage at the prelube relay. The code is logged.
338-6 Engine Pre-Lube Pump Relay current above normal The ECM detects a short circuit at the prelube relay. The ECM has the ability to automatically lubricate the engine before cranking. This may increase the life of certain engine parts by lubricating the parts before the starting motor is engaged.The prelubrication system is activated when the start/run/stop switch is turned to the START position. The ECM prevents the starting motor from engaging while the pump builds pressure in the engine oil system. After a short period of time, the starting motor is allowed to engage. The start/run/stop switch must be left in the START position for the duration of the prelube cycle in order to ensure that the engine is properly lubricated before start-up.A test on Caterpillar Electronic Technician (ET) allows the technician to activate the prelube system. The test is functional only when the engine speed is zero rpm. The test is accessed by selecting the following menus on Cat ET:

Turn the breaker for the ECM to the OFF position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors in the circuit. Refer to Troubleshooting, "Inspecting Electrical Connectors" for the proper procedure for inspecting system wiring.
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 allen head screw for each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Inspecting Electrical Connectors" for details.
Check the harness and the wiring for abrasion and for pinch points. Expected Result:All connectors, pins, and sockets are completely 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 completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. CHECK FOR ACTIVE DIAGNOSTIC CODES
Connect Cat ET to the service tool connector.
Turn the breaker for the ECM to the ON position.
Monitor the active diagnostic code screen on Cat ET. Check the prelube system for an active diagnostic code. Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Select diagnostic tests from Cat ET.
Select the "Override Parameters" screen on Cat ET.
Activate the prelube override.
Monitor the active diagnostic code screen on Cat ET. Check the prelube system for an active diagnostic code. Note: Wait at least 30 seconds in order for the diagnostic code to become active.
Disable the prelube override. Expected Result:No diagnostic codes are active.Results:
OK - No diagnostic codes are active, but a problem is suspected in the prelube system. Proceed to Test Step 6.
Not OK - A -6 diagnostic code is active at this time. Proceed to Test Step 3.
Not OK - A -5 diagnostic code is active at this time. Proceed to Test Step 4.Test Step 3. CREATE AN OPEN AT THE PRELUBE RELAY
Turn the breaker for the ECM to the OFF position.
Disconnect wire F705-PK(Pink) from terminal 86 of the prelube relay.
Turn the breaker for the ECM to the ON position.
Monitor the active diagnostic code screen on Cat ET. Check the prelube system for an active diagnostic code. Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Select diagnostic tests from Cat ET.
Select the "Override Parameters" screen on Cat ET.
Activate the prelube override.
Monitor the active diagnostic code screen on Cat ET. Check the prelube system for an active diagnostic code. Note: Wait at least 30 seconds in order for the diagnostic code to become active.
Turn the breaker for the ECM to the OFF position. Expected Result:A -6 diagnostic code was active for the prelube relay. After creating an open at the prelube relay, a -5 diagnostic code is now active for the prelube relay.Results:
OK - A -6 diagnostic code was active before disconnecting the wire. A -5 diagnostic code became active after disconnecting the wire. The harness and the ECM are OK. The problem may be in the prelube relay.Repair: Verify that wire A268-BK(Black) is not shorted to another wire in the harness. Check wire A268-BK(Black) for continuity to the ECM. If wire A268-BK(Black) is OK, install a new prelube relay. Verify that there are no active diagnostic codes for the prelube relay. Clear any logged diagnostic codes.STOP
Not OK - A -6 diagnostic code remains active. Th
