Troubleshooting Test Steps    Values    Results    
1. Check for Associated Diagnostic Trouble Codes
A. Establish communication between the Caterpillar Electronic Technician (ET) and the ECM. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
Troubleshoot any associated diagnostic codes that are present before continuing with this procedure.
   
Associated Codes    
Result: An associated diagnostic trouble code is not active or logged.
Proceed to Test Step 2.
Result: An associated code is active or logged.
Repair: Troubleshoot the associated codes before continuing with this procedure.
Refer to Troubleshooting, "Diagnostic Trouble Codes" in order to troubleshoot the associated diagnostic code.
   
2. Starting Aids (if applicable)
A. If cold ambient conditions exist, check the operation of the starting aids.
B. Verify that the starting aid is operating correctly.
   
Starting Aids    
Result: The starting aid is operating correctly.
Proceed to Test Step 3.
Result: The starting aid is not operating correctly.
Repair: Refer to the appropriate circuit test in order to troubleshoot the starting aid.
   
3. Excessive Loads
A. Check for an excessive load on the engine.
B. If necessary, disengage the driven equipment and test the engine.
   
Excessive Load    
Result: The are excessive loads on the engine.
Repair: Reduce the load on the engine. Return the unit to service.
Result: The are not excessive loads on the engine.
Proceed to Test Step 4.
   
4. Inspection of the Fuel Supply
A. Visually check the fuel level in the fuel tank. Do not rely on the fuel gauge only.
B. Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
C. Check the fuel quality.
Make sure that the fuel meets the requirements of Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations ".
D. Inspect the fuel system.
Refer to Systems Operation/Testing and Adjusting, "Fuel System" for additional information.
Cold weather adversely affects the characteristics of the fuel. Refer to the engine Operation and Maintenance Manual for information on improving the characteristics of the fuel during cold-weather operation.
   
Fuel Level    
Result: The fuel level is OK.
Proceed to Test Step 5.
Result: The fuel level is not OK.
Repair: Fill the tank.
If necessary, add fuel. If the engine has been run out of fuel, purge the air from the fuel system.
   
5. Worn Battery
A. Verify that the battery is no longer able to hold a charge. Refer to Systems Operation/Testing and Adjusting for the correct procedure.
   
Battery    
Result: The battery will no longer hold a charge.
Repair: Replace the battery. Refer to Disassembly and Assembly for the correct procedure.
Result: The battery will hold a charge.
Proceed to Test Step 6.
   
6. Switched Battery Circuit
A. Inspect the battery cables, wiring, and connections in the charging circuit.
B. Verify that a switched battery circuit drained the battery by being left in the ON position.
C. Charge the battery. Verify that the battery is able to maintain a charge. Refer to Systems Operation/Testing and Adjusting for the correct procedure.
   
Battery Circuit    
Result: The battery circuit is OK.
Proceed to Test Step 7.
Result: The battery circuit is not OK.
Repair: Clean all connections and tighten all connections. Replace any faulty parts, if necessary.
   
7. Alternator
A. Inspect the condition of the alternator. Refer to Troubleshooting, "Alternator Problem" for the correct procedure.
    Alternator    
Result: The condition of the alternator is OK.
Proceed to Test Step 8.
Result: The condition of the alternator is not OK.
Repair: Replace or repair the alternator.
   
8. Starter Engagement
A. Attempt to start the engine while you observe the status of the relay for the starting motor on Caterpillar Electronic Technician.
    Starter Engagement    
Result: The relay for the starting motor indicates that the engine should crank but no cranking occurs.
Repair: Troubleshoot the starting circuit.
Result: The relay for the starting motor indicates that the engine should crank and cranking occurs.
Proceed to Test Step 9.
   
9. Crank Cycle
A maximum of one crank cycle per overcrank is recommended.
A. Make sure that the engine can be cranked for a sufficient amount of time.
    Crank Cycle    
Result: The engine cannot be cranked for a sufficient amount of time.
Repair: Use Cat ET to check the "Cycle Crank Time" and the "Overcrank Time" parameters. Remember that the purge cycle is part of the total crank cycle. Reprogram the parameters, if necessary.
