Event Codes
J1939 Codes and Description Conditions which Generate this Code System Response
110-15 Engine Coolant Temperature : High - least severe (1) The engine coolant temperature is above the trip point temperature for the programmed delay time. The code is logged.
110-16 Engine Coolant Temperature : High - moderate severity (2) The code is logged.
Engine power is derated.
110-00 Engine Coolant Temperature : High - most severe (3) The code is logged.
If the ground speed of the vehicle is zero and the parking brake is set, the engine will be shut down.
4193-0 Engine Coolant Pump Outlet Temperature : High - most severe (3) The engine coolant temperature is above the trip point temperature for the programmed delay time. This code is generated by the Temperature Control Module (TCM) (MID No. 094). The code is logged.
The TCM commands the valve to open fully. Probable Causes

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Caterpillar Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Product Status Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Determine if the event code that directed to this story is present.
D. Look for active diagnostic codes that are associated with the system for the event code that directed to this story.
110-0, 110-15, 110-16 or 4193-0
Result: An associated code is present.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A 110-0, 110-15, 110-16 or 4193-0 code is present.
Proceed to the next step.
Result: No active codes
STOP
2. Low Coolant Level
A. Inspect the coolant level.
Coolant
Result: The coolant level is OK.
Proceed to the next step.
Result: The coolant level is NOT OK.
Repair: Add coolant
If the problem is not resolved, proceed to the next step.
3. Radiator
A. Check the cooling fins on the radiator for dirt and/or for debris.
B. Check the cooling fins on the radiator for damage.
C. Check the radiator for internal blockage. Check the temperature difference between the inlet and the outlet of the radiator.
Radiator
Result: The cooling fins are clean.
Continue with this step.
Result: The cooling fins are not clean.
Repair: Remove dirt and/or debris.
Result: The cooling fins are damaged.
Repair: Refer to the Systems Operation/Testing and Adjusting manual for instructions for testing and inspecting the cooling system.
Result: The cooling fins are not damaged.
Continue with this step.
Result: The radiator has an internal blockage.
Repair: Clean the radiator or perform the necessary repairs.
Result: The radiator does not have an internal blockage
If the problem is not resolved, proceed to the next step.
4. Coolant Leak
A. Check the cooling system for leaks.
1. Inspect the coolant for presence of bubbles.
Note: Cavitation will reduce the efficiency of the cooling system.
2. Check the cooling system for combustion gases.
Leak
Result: The cooling system is OK.
Proceed to the next step.
Result: The cooling system is NOT OK.
Repair: Or replace as necessary.
If the problem is not resolved, proceed to the next step.
5. Engine Cooling Fan
A. Check for proper operation of the cooling fan.
Fan
Result: The cooling fan is OK.
Proceed to the next step.
Result: The cooling fan is not OK.
Repair: Repair or replace as necessary.
If the problem is not resolved, proceed to the next step.
6. Pressure Cap for the Radiator
A. Check operation of the pressure relief valve and the radiator cap.
Relief Valve
Result: The pressure relief valve is OK.
Result: The pressure relief valve is NOT OK.
Repair: If necessary, clean the seal and the seating surface in the cap. Check that the seating surface on the fill neck of the radiator is clean and undamaged. If the sealing components of the pressure cap are suspect, replace the cap.

7. Temperature Control Module
A. Perform the following procedure:
1. Visually inspect the wiring from the TCM to the coolant temperature sensor and from the temperature control module to the power supply. Visually inspect the 12-pin connector and the 8-pin connector at the temperature control module. Check for a tight connection at the connectors..
B. Check for proper operation of the electronic fluid temperature control:
1. Ensure that the keyswitch is in the OFF position. Turn the electrical disconnect to the OFF position.
2. Remove cover bolts (4) from the motor assembly. Remove the inspection cover from the motor.
3. Use the appropriate wrench to rotate the main shaft extension. Ensure that the shaft rotates freely. Rotate the shaft in order to ensure that the piston is not positioned at one of the end stops of the valve.
4. Visually inspect main shaft extension (3) for rotation while you establish power to the ECM and to the keyswitch circuit. The shaft will rotate several times during the powerup sequence.
5. During the powerup sequence, listen for the valve to travel to the end stop. Listen for the piston to hammer the end stop in order to establish the valve position.
6. With the electrical disconnect in the ON position, disconnect
