Repair: Troubleshoot the code and then reset the histogram.
Result: A diagnostic code is not present.
Proceed to Test Step 2.
2. Visible Faults
A. Check that the fuel supply valve (if equipped) is in the OPEN position.
B. Check for the correct level of fuel, oil, and coolant.
C. Check for water in the primary fuel filter/water separator.
D. If the ambient temperature is below 0 °C (32 °F), check the specification of engine oil and oil for the machine.
E. Visually inspect the engine for the following faults:
Missing components
Damaged components
Damaged electrical cables or loose electrical cables
Oil leaks
Fuel leaks
All fuel filters are correctly installed.
F. Check that the battery voltage is correct.
G. Use the electronic service tool to check the average cranking speed of the engine.
Visible faults
Result: The fuel supply valve (if equipped) is not in the OPEN position.
Repair: Move the fuel supply valve to the OPEN position.
Result: The level of fuel, oil, or coolant is not correct.
Repair: Replenish any fluids with an incorrect level.
Result: Water is present in the primary fuel filter/water separator.
Repair: Drain any water from the primary fuel filter/water separator.
Result: The correct specification of engine oil and oil for the machine is not in use.
Repair: Replenish the system with oil of the correct specification for the ambient conditions.
Result: Battery voltage is low.
Repair: Check the batteries. Refer to Troubleshooting, "Battery Problem".
Result: The cranking speed is less than 150 rpm.
Repair: Investigate the cause of the low cranking speed and rectify, as necessary.
Result: All checks are OK.
Proceed to Test Step 3.
3. Air Intake and Exhaust System
A. Check the air filter restriction indicator, if equipped.
B. Check the air intake and exhaust systems for the following defects:
Blockages
Restrictions
Damage to lines or hoses
Air and Exhaust System restrictions
Result: The air filter is restricted.
Repair: Replace the air filter.
Result: There are system restrictions.
Repair: Refer to Systems Operation/Testing and Adjusting, "Air Inlet and Exhaust System" for additional information on the air inlet and exhaust systems.
Result: The air intake and exhaust system is OK.
Proceed to Test Step 4.
4. Speed/Timing Sensors
A. Crank the engine and observe the engine speed on the electronic service tool status screen. Refer to Troubleshooting, "Speed/Timing - Test" for additional information.
Upon initial cranking, the status for engine speed may indicate that the engine speed signal is abnormal. This message will be replaced with an engine speed once the ECM is able to calculate a speed from the signal.
Speed/timing sensor
Result: The speed/timing sensors are not operating correctly.
Repair: Test the speed/timing sensors. Refer to Troubleshooting, "Speed/Timing - Test".
Result: The speed/timing sensors are operating correctly.
Proceed to Test Step 5.
5. Low-Pressure Fuel System
A. Visually check the fuel tank for fuel.
Note: The fuel gauge may be faulty.
B. If the temperature is below 0 °C (32 °F), check for solidified fuel (wax).
C. Check the primary filter/water separator for water in the fuel.
D. Check for fuel supply lines that are restricted or not correctly installed.
E. Check for air in the fuel system and that the fuel system is primed.
F. Check the diesel fuel for contamination. Refer to Systems Operation, Testing, and Adjusting, "Fuel Quality - Test".
Low-pressure fuel system
Result: The fuel tank level is low.
Repair: Fill the fuel tank.
Result: The fuel contains solidified wax.
Repair: Replace the fuel with fuel of the correct specification for the ambient conditions.
Result: There are fuel supply lines that are restricted or not correctly installed.
Repair: Install the fuel lines correctly. Replace any damaged or restricted fuel lines.
Replace the primary fuel filter and the secondary fuel filters. Refer to the Operation and Maintenance Manual for further information.
Result: There is air in the fuel system.
Repair: Prime the fuel system. Refer to Systems Operation, Testing, and Adjusting, "Fuel System - Prime".
Result: The diesel fuel is contaminated.
Repair: Drain the fuel tank and the fuel system.
Replace the primary fuel filter and the secondary fuel filters. Refer to the Operation and Maintenance Manual for further information.
Fill and prime the fuel system with fuel of the correct specification. Refer to Systems Operation, Testing, and Adjusting, "Fuel System - Prime".
Result: The low-pressure fuel system is OK.
Proceed to Test Step 6.
6. High-Pressure Fuel System
A. Use the electronic service tool to check the absolute fuel rail pressure while the engine is cranking at a minimum speed of 150 rpm.
High-pressure fuel system
Result: The absolute fuel rail pressure is less than 25 MPa (3625 psi).
Repair: Check for fuel leaks in the high-pressure fuel system. Rectify any fuel leaks and then recheck the pressure in the fuel rail.
Use the electronic service tool to perform a solenoid test on the fuel injection pump. Refer to Troubleshooting, "Solenoid Valve - Test".
If the fuel control valve solenoid test fails, replace the high-pressure fuel pump suction control valve and solenoid assembly.
Check the Pressure Limiting Valve (PLV) in the fuel rail for leakage. If the valve is leaking, replace the valve and recheck the pressure in the fuel rail.
Check for fuel in the engine oil system. If fuel is suspected in the oil system, take an engine oil sample for analysis. Refer to the Operation and Maintenance Manual, "Engine Oil Sample - Obtain".
If the analysis confirms that there is fuel in the engine oil system, investigate the cause.
Result: The absolute fuel rail pressure is greater than 25 MPa (3625 psi).
