Code and Description     Conditions which Generate this Code     System Response    
617-5 Inlet Air Heater Relay : Current Below Normal     The Electronic Control Module (ECM) detects a current flow that is below normal during an attempt to energize the air inlet heater relay.     The code is latched. The code is logged.
The air inlet heater will be disabled if an open has occurred in the wiring in the circuit. The air inlet heater will be energized continuously if a short to the +Battery has occurred in the wiring in the circuit.    
617-6 Inlet Air Heater Relay : Current Above Normal     The ECM detects excessive current during an attempt to energize the air inlet heater relay.     The code is latched. The code is logged.
The air inlet heater will be disabled.
The engine may experience hard starting and/or the engine may emit excessive white smoke.    Use the following information in order to check the operation of the air inlet heater and the air inlet heater relay.The following background information is related to the operation of the air inlet heater:The air inlet heater is used to improve the ability of the engine to start when the engine is cold. A reduction of white smoke and reduced emission levels are also benefits of the air inlet heater.The ECM controls the operation of the air inlet heater and the ECM controls the operation of the lamp for the air inlet heater through the air inlet heater relay.The operation of the air inlet heater is determined by three different cycle times:
Mode of powerup and preheat
Mode of engine cranking
Mode of engine startedMode of Powerup and PreheatRegardless of temperature, the heater and the lamp for the heater will be activated for two seconds when the ECM is first powered (lamp check).The ECM then calculates the sum of the coolant temperature plus the intake manifold air temperature. This sum must be below the following temperature in order for the air inlet heater to be activated prior to engine cranking:

Less than
1675 m (5500 ft)    
25 °C (109 °F)    
Greater than
1675 m (5500 ft)    
53 °C (159 °F)    If the sum of the temperatures is below the temperature that is mentioned in Table 2, the air inlet heater will be activated for a maximum of 30 seconds during the preheat cycle.If the operator attempts to start the engine prior to the completion of preheat, the ECM reverts to the mode of engine cranking.Mode of Engine CrankingDuring engine cranking, the ECM first checks if the coolant temperature is less than 0 °C (32 °F). If this condition is true, the ECM activates the heater during engine cranking.If the preceding condition is false, the ECM calculates the sum of the coolant temperature plus the intake manifold air temperature. This sum must be below the following temperature in order for the air inlet heater to be activated during engine cranking:

63 °C (178 °F)    If either of the preceding conditions are true, the ECM will activate the heater until the engine starter is disengaged. If the engine fails to start, the ECM reverts to the mode of powerup and preheat. If the engine starts, the ECM proceeds to the mode of engine started.Mode of Engine StartedAfter the engine has started, the same combination of intake manifold air temperature and coolant temperature will determine the state of the heater. The cycle has two strategies:
Continuous operation
Intermittent operationContinuous OperationDuring continuous operation of the air inlet heater, the heater may operate continuously for a maximum of seven minutes after the engine has started. The ECM will exit the mode of continuous operation early if the sum of the coolant temperature plus the intake manifold air temperature exceeds the following temperatures:

Greater than
1675 m (5500 ft)    
63 °C (178 °F)    When this temperature is exceeded, the air inlet heater is turned off and the mode of engine started is completed.If the temperatures for the preceding strategy are not met in seven minutes, the strategy for intermittent operation will be performed.Intermittent OperationDuring the strategy for intermittent operation, the ECM cycles the power to the air inlet heater in ten second intervals.This strategy will be effective for a maximum of 13 minutes after the strategy has begun. The ECM will exit the mode of intermittent operation early if the sum of the coolant temperature plus the intake manifold air temperature exceeds the following temperatures:
