Information:
Use this procedure in order to troubleshoot low engine coolant pressure. Also, use this procedure if the following event code is active.
Table 1
Event Code
J1939 Code and Description Conditions which Generate this Code System Response
109-17 Engine Coolant Pressure : Low - least severe (1) The engine coolant pressure is below the map-based trip point pressure for the programmed delay time. The code is logged. Probable Causes
Low coolant level
Damaged coolant lines
Radiator blockage
Blockage of the oil cooler heat exchanger
Engine coolant pump outlet pressure sensor
Jacket water coolant pumpRecommended Actions
Table 2
Troubleshooting Test Steps Values Results
1. Check for Codes
A. Establish communication between Caterpillar Electronic Technician (ET) and the Electronic Control Module (ECM).
C. Determine if the diagnostic trouble code that directed to this procedure is present.
D. Look for active diagnostic codes that are associated with the system for the event code that directed to this procedure.
E2112
Result: A diagnostic code is present.
Repair: Troubleshoot any codes before continuing with this procedure.
Verify that the repair eliminated the problem.
Result: A 109-17 code is present.
Proceed to Test Step 2.
Result: No active codes
STOP
2. Check for Low Coolant Level
Level
Result: Coolant level is OK.
Proceed to Test Step 3.
Result: Coolant level is NOT OK.
Repair: Add coolant.
Verify that the repair eliminated the problem.
3. Check for Damaged Cooling System Piping
A. Inspect the piping for the following conditions:
- Damage
- Crushing
- Bending
B. Inspect the rubber boots: Look for signs of cracking, and collapse.
Damage
Result: The system piping is OK.
Proceed to Test Step 4.
Result: The system piping is NOT OK.
Repair: Repair or replace any damaged piping or boots.
Verify that the repair eliminated the problem.
4. Inspect the Radiator for Blockage
A. Check the radiator for internal blockage.
B. Check the temperature difference between the inlet and the outlet of the radiator.
Blockage
Result: The radiator is OK.
Proceed to Test Step 5.
Result: The radiator is NOT OK.
Repair: Clean the radiator or perform the necessary repairs.
Verify that the repair eliminated the problem.
5. Check if the Oil Cooler has a Blockage
A. Inspect the inlet side of oil cooler for debris and blockage.
Blockage
Result: The oil cooler is OK.
Proceed to Test Step 6.
Result: The oil cooler is NOT OK.
Repair: Clean the oil cooler or perform the necessary repairs.
Verify that the repair eliminated the problem.
Steam or hot coolant can cause severe burns.Do not loosen the filler cap or the pressure cap on a hot engine.Allow the engine to cool before removing the filler cap or the pressure cap.

6. Check the Engine Coolant Pump Outlet Pressure Sensor
A. While the engine is off and the cooling system is cool, remove any pressure from the system by carefully removing the pressure cap.
B. Compare the "Engine Coolant Pump Outlet Pressure (Absolute)" to the status of the "Atmospheric Pressure" parameter.
Sensor
Result: For sensors that are working correctly, the pressures will be comparable. The sensor is OK.
Proceed to Test Step 7.
Result: The sensor is NOT OK.
Repair: Replace the damaged components. Refer to the Disassembly and Assembly manual.
Verify that the repair eliminated the problem.
7. Install a Mechanical Gauge to Verify the Coolant Pressure
A. Install a mechanical gauge near the coolant pressure sensor.
B. Use the
