Test Step 1. Check for Connector Damage.
Turn the circuit breaker for the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Check connectors and wiring for the following problems: damage, corrosion, abrasion and incorrect attachment.Expected Result:The connectors and wiring should be free of the following problems: damage, corrosion, abrasion and incorrect attachment.Results:
OK - Proceed to test step 2.
Not OK - Repair: Repair the connectors and/or wiring or replace the connectors and/or wiring. Stop.Test Step 2. Check the ECS.
Verify that the ECS is operating correctly.Expected Result:Results:
OK - Proceed to test step 3.
Not OK - Proceed to test step 4.Test Step 3. Check the Engine Prelube Pressure Switch.
Turn the ECS to the OFF/RESET position.
Disconnect ECM connector J1/P1.
Measure the resistance between the engine prelube pressure switch P1-20 and the Digital Return P1-29.
Reconnect the ECM connector P1.Expected Result:The resistance should be greater than 20,000 Ohms.Results:
OK - The engine prelube pressure switch is not active. Proceed to test step 5.
Not OK - The engine prelube pressure switch is active. Verify that the engine does not have a residual oil pressure that is high enough to activate the switch. If there is no residual oil pressure the switch is not operating correctly or there is a problem with the wiring. Proceed to test step 6.Test Step 4. Perform the following test: Engine Control Switch (ECS)Results:
OK - Stop.
REPAIRED, OK - Stop.Test Step 5. Check the Status of the Switch.
Turn the ECS to the OFF/RESET position.
Turn the circuit breaker for the battery to the ON position.
Turn the ECS to the STOP position.
Connect the ET.
Observe the parameters for the engine prelube and for the ignition switch.Expected Result:The parameter for the engine prelube should display "OFF". The parameter for the ignition switch should display "OFF".Results:
OK - Proceed to test step 7.
Prelube Disabled - Repair: Repair the connectors and/or wiring or replace the connectors and/or wiring. Stop.
Ignition Switch Not OFF - Proceed to test step 4.Test Step 6. Check the Engine Prelube Pressure Switch.
Turn the ECS to the OFF/RESET position.
Disconnect the wires from terminal 1 and terminal 2 of the engine prelube pressure switch.
Measure the resistance between terminal 1 and terminal 2 of the switch.Expected Result:The resistance should be greater than 20,000 Ohms.Results:
OK - Repair: Repair the connectors and/or wiring or replace the connectors and/or wiring. Stop.
Not OK
