Information:
Use this procedure to troubleshoot a high aftercooler coolant temperature. Also, use this procedure if one of the following event codes is active or logged.
Table 1
J1939 Code and Description CDL Code and Description Comments
52-0
Engine Intercooler Temperature : High - most severe (3) E771 (3)
High Aftercooler Temperature The ECM may shut down the engine.
The code is logged.
52-15
Engine Intercooler Temperature : High - least severe (1) E771 (1)
High Aftercooler Temperature The code is logged. If the engine is shut down due to a high aftercooler temperature, cycle power to the engine ECM to restart the engine.Probable Causes

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 Coolant Level for the Separate Circuit Aftercooler (SCAC) System
Coolant Level
Result: The coolant level is OK.
Proceed to Test Step 3.
Result: The coolant level is NOT OK.
Repair: Add coolant. Check for leaks.
If the problem is not resolved, proceed to Test Step 3.
3. Inspect the Radiator for the SCAC System
A. Check the radiator fins for dirt, debris, and/or damage.
B. Check for restrictions and internal blockage.
C. Ensure that the radiator size is sufficient. An undersized radiator does not have enough area for the effective release of heat. An undersized radiator may cause the engine to run at a temperature that is higher than normal. The normal temperature is dependent on the ambient temperature.
Radiator
Result: The radiator fins are not damaged and the radiator does not have a blockage.
Proceed to Test Step 4.
Result: The radiator fins are damaged and/or there is a blockage.
Repair: Remove any dirt or debris, straighten any bent fins, and remove any blockage.
If the problem is not resolved, proceed to Test Step 4.
4. Check for Air Leaks into the SCAC System
A. Inspect the cooling system for leakage. Refer to Testing and Adjusting, "Cooling System - Test" for additional information.
Leaks
Result: There is not any leakage.
Proceed to Test Step 5.
Result: There is leakage.
Repair: Repair any leaks immediately.
If the problem is not resolved, proceed to Test Step 5.
5. Inspect the SCAC Piping
A. Perform a visual inspection of the piping for the SCAC system. Look for piping that is damaged, crushed, or bent.
Piping
Result: The piping is OK.
Proceed to Test Step 6.
Result: The piping is NOT OK.
Repair: Repair or replace any damaged piping.
If the problem is not resolved, proceed to Test Step 6.
6. Check for Proper Operation of the Cooling Fan
Cooling Fan
Result: The cooling fan is operating correctly.
Proceed to Test Step 7.
Result: The cooling fan is not operating correctly.
Repair: Repair or replace the cooling fan.
If the problem is not resolved, proceed to Test Step 7.
7. Inspect the Pressure Relief Valve
A. If the SCAC system is pressurized, pressure-test the SCAC system. Refer to Testing and Adjusting, "Testing the Cooling System" for additional information.
B. Check that the seating surfaces of
