Recommended Actions
Engine Shutdown Switches
The engine shutdown switches should be in the RUN position. Ensure that the shutdown switches are in the proper positions. Use Caterpillar Electronic Technician (ET) to verify the status of the "EMCP" and the "Remote E-Stop Switch" parameters. When a shutdown occurs, the Electronic Control Module (ECM) must be powered down for at least 15 seconds prior to attempting to start the engine.Diagnostic Codes and Event Codes
Connect Cat ET to the service tool connector. Check for active diagnostic codes and event codes.Look for active diagnostic codes and event codes that will prevent the engine from being cranked. During an engine shutdown event, the ECM latches the shutdown until the control system is reset. The ECM prevents the engine from cranking. Cycle the power to the ECM in order to restart the engine.Batteries
Check the charge on the engine's batteries. Charge the batteries, if necessary. Refer to Special Instruction, SEHS7633, "Battery Test Procedure".Load test the batteries. Refer to Special Instruction, SEHS9249, "Use of 4C-4911 Battery Load Tester for 6, 8 and 12 Volt Lead Acid Batteries".Engine Starting System
If the application is equipped with an electric starting system, perform the following procedure:
Check the wiring to the starting motor solenoid. Refer to the vehicle's electrical schematic.
Check the engine start switch and the engine start relay for electrical power.
Check the starting motor cables. If the starting motor cables are corroded, remove the starting motor cables and clean the starting motor cables.
Test the operation of the starting motors.
If the application is equipped with an air start system, perform the following procedure:
Verify that the air start system has an adequate supply pressure for starting.
Check the wiring to the air start relay that is for the air starting motors. Refer to the application's electrical schematic.
Check the engine start switch for electrical power.
Check the air start supply lines. If the supply lines are leaking or damaged, repair the lines.
Test the operation of the air start motors.
If the application is equipped with a hydraulic starting system, perform the following procedure:
Verify that the hydraulic starting system has an adequate supply pressure for starting.
Check the wiring to the start relay that is for the starting motors. Refer to the application's electrical schematic.
Check the engine start switch for electrical power.
Check the hydraulic starting lines. If the supply lines are leaking or damaged, repair the lines.
Test the operation of the hydraulic starting motors. Flywheel Ring Gear
Inspect the flywheel ring gear for damage.Driven Equipment
Verify that the driven equipment is operating correctly.Engine Accessories
Remove engine accessories that may prevent the engine cranking and inspect the accessories.The following accessories may prevent the engine cranking:
Engine oil pump
High pressure fuel pumpHydraulic Cylinder Lock
Check for fluid in the cylinders (hydraulic cylinder lock) by removing the individual injectors.Note: Fuel will flow from the cylinder head into the cylinders when a electronic unit injector is removed.Internal Engine Problem
Disassemble the engine. Refer to the engine's Disassembly and Assembly manual. Inspect the internal components for the following conditions:
Seizure
Broken components
Bent componentsConfiguration Parameters
Use Cat ET to check the settings of the configuration parameters that are related to the engine starting system. Ensure that the configuration of the parameters match the installation.Use Cat ET or the EMCP to view the engine state for the engine, the prelube, and the engine starting system. If necessary, power down the ECM in order to reset the Engine Management System (EMS) for the engine.
