EID E017Conditions Which Generate This Code:The Electronic Control Module (ECM) detects engine coolant temperature that exceeds the trip point temperature. Information on default settings and ranges for this event can be found in Troubleshooting, "Event Codes".System Response:The ECM will log the event.Possible Performance Effect:
There are no performance effects.Troubleshooting:There may be a problem with the engine.Test Step 1. Check the Engine's Cooling System
Verify that the cooling system is filled to the proper level. If the coolant level is too low, air will get into the cooling system. Air in the cooling system will cause a reduction in coolant flow.
Check the radiator. If the engine is equipped with a SCAC cooling system or a heat exchanger, check for a restriction to coolant flow in the system.
Check for debris or damage between the fins of the radiator core. Debris between the fins of the radiator core restricts air flow through the radiator core.
Check internally for debris, dirt, or deposits on the radiator core. Debris, dirt, or deposits will restrict the flow of coolant through the radiator.
Check the mixture of antifreeze and water. Ensure that the recommendations in the Operation and Maintenance Manual are followed.
Check the water temperature regulators. A water temperature regulator that does not open, or a water temperature regulator that only opens part of the way can cause overheating.
Check the water pump. A water pump with a damaged impeller does not pump enough coolant. Remove the water pump and check for damage to the impeller.
If the cooling system for this application is equipped with a fan, check the operation of the fan. A fan that is not turning at the correct speed can cause improper air speed across the radiator core. The lack of proper air flow across the radiator core can cause the coolant not to cool to the proper temperature differential.
Check for air in the cooling system. Air can enter the cooling system in different ways. The most common causes of air in the cooling system are the incorrect filling of the cooling system and combustion gas leakage into the cooling system. Combustion gas can get into the system through inside cracks, a damaged cylinder head, or a damaged cylinder head gasket.
Check the cooling system hoses and clamps. Damaged hoses with leaks can normally be seen. Hoses that have no visual leaks can soften during operation. The soft areas of the hose can become kinked or crushed during operation. These areas of the hose can restrict the coolant flow. Hoses become soft and/or get cracks after a period of time. The inside of a hose can deteriorate, and the loose particles of the hose can restrict the coolant flow.
If the cooling system for this application is equipped with an expansion tank, check the shunt line for the expansion tank. The shunt line must be submerged in the expansion tank. A restriction of the shunt line from the expansion tank to the inlet of the jacket water pump will cause a
