Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A code is active or logged.
Proceed to Test Step 2.
2. Check the Aftercooler (if equipped)
A. Check for leaks and/or damage to the aftercooler.
Restrictions
Result: The aftercooler is OK.
Proceed to Test Step 3.
Result: The aftercooler is NOT OK.
Repair: Clear the restrictions, replace any damaged lines, or replace the aftercooler.
If the problem is not resolved, proceed to Test Step 3.
3. Check the Operation of the Cooling Fan
A. Verify that the cooling fan that is being used to transfer heat from the ATAAC is working properly.
B. If the fan is belt driven, verify that the belt tension is adequate. Also, verify that the clutch is operating properly.
C. If the fan is hydraulically driven, verify that there is no leakage around the motor and that the pressure for the fan is adequate.
Cooling Fan
Result: The fan drive system is not working properly.
Repair: Make the necessary adjustments to the clutch or the belt tension if the fan is mechanically driven . Refer to the machine Test and Adjust for the proper procedure. Repair leaks or make the necessary adjustments to the motor or the hydraulic pump if the fan is hydraulically driven . Refer to Testing and Adjusting for the proper procedure.
If the problem still exists, proceed to Test Step 4.
Result: The fan drive system is working properly.
If the problem is not resolved, proceed to Test Step 4.
4. Check the Operation of the Charge Air Cooler Outlet Temperature Sensor
A. Remove the charge air cooler outlet temperature sensor. Allow the charge air cooler outlet temperature sensor to rest in ambient air for two minutes.
B. Connect to the engine ECM by using Cat ET.
C. Monitor the value of the charge air cooler outlet temperature sensor on Cat ET.
Sensor
Result: The value of the charge air cooler outlet temperature sensor is within −9° C ( 15° F) of the ambient temperature.
Repair: Reinstall the sensor. Torque the sensor to the proper specifications. Return the unit to service.
Result: The value of the charge air cooler outlet temperature sensor is not within −9° C ( 15° F) of the ambient temperature.
Repair: Replace the charge air cooler outlet temperature sensor. Return the unit to service.
Verify that the repair eliminated the problem.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
